Anemia Beyond Iron Deficiency: Hidden Causes You Shouldn’t Ignore

Feeling tired all the time, becoming breathless after minor activity, experiencing dizziness, headaches, weakness or a racing heartbeat are symptoms many people casually attribute to stress, poor sleep or nutritional deficiency.

Anemia Beyond Iron Deficiency: Hidden Causes You Shouldn’t Ignore

Anemia is often treated as an iron problem. But what if your iron levels are normal and your hemoglobin is still low?

Feeling tired all the time, becoming breathless after minor activity, experiencing dizziness, headaches, weakness or a racing heartbeat are symptoms many people casually attribute to stress, poor sleep or nutritional deficiency.

Sometimes, however, these symptoms are signs of anemia—a condition in which the blood does not carry enough oxygen to the body's tissues.

Iron deficiency is one of the most common causes of anemia, but it is far from the only one. Anemia can also develop because of vitamin B12 or folate deficiency, chronic kidney disease, inflammation, autoimmune disorders, inherited blood disorders, excessive destruction of red blood cells, blood loss, bone marrow disorders and, in some cases, blood cancers.

This is why repeatedly taking iron supplements without understanding the underlying cause may not solve the problem.

For patients with persistent, unexplained or complex anemia, evaluation by an experienced hematologist can be important. In India, Dr. Rahul Bhargava, Principal Director & Chief – Hematology, Hemato-Oncology & Bone Marrow Transplant at Fortis Memorial Research Institute (FMRI), Gurugram, specializes in complex blood disorders and hematological conditions. Fortis lists his areas of expertise across hematology, hemato-oncology and bone marrow transplantation.

For international patients looking for advanced hematology evaluation and treatment in India, understanding the hidden causes of anemia is an important first step.


What Is Anemia?

Anemia occurs when the blood has fewer healthy red blood cells than normal or when there is not enough hemoglobin to transport oxygen effectively throughout the body.

Hemoglobin is the oxygen-carrying protein inside red blood cells. When hemoglobin is low, tissues and organs may receive less oxygen, which can result in symptoms such as fatigue, weakness, shortness of breath, dizziness and headaches.

Anemia is not a single disease.

It is better understood as a sign or consequence of an underlying problem.

That underlying problem could be relatively straightforward, such as iron deficiency, or more complex, such as:

  • Vitamin B12 deficiency
  • Folate deficiency
  • Chronic kidney disease
  • Chronic inflammation
  • Autoimmune disease
  • Ongoing blood loss
  • Hemolytic anemia
  • Thalassemia and other inherited blood disorders
  • Bone marrow disorders
  • Certain cancers
  • Medication-related effects
  • Nutritional or absorption disorders

The correct treatment depends on identifying why the anemia is occurring.


Is Every Case of Anemia Caused by Iron Deficiency?

No.

Iron-deficiency anemia is common, but a low hemoglobin level does not automatically mean that a person needs iron supplements.

The body needs iron to produce hemoglobin, but red blood cell production also depends on adequate vitamin B12, folate, healthy bone marrow, appropriate kidney function and a number of other biological processes.

Anemia can broadly develop through three mechanisms:

1. The body does not make enough red blood cells

This can occur with:

  • Iron deficiency
  • Vitamin B12 deficiency
  • Folate deficiency
  • Kidney disease
  • Chronic inflammation
  • Bone marrow disorders
  • Certain medications
  • Some cancers

2. The body loses blood

Blood loss may occur through:

  • Heavy menstrual bleeding
  • Gastrointestinal bleeding
  • Ulcers
  • Polyps
  • Certain cancers
  • Surgery or trauma
  • Repeated blood loss from medical procedures

3. Red blood cells are destroyed too quickly

This is known as hemolysis or hemolytic anemia.

It can occur because of:

  • Autoimmune conditions
  • Inherited disorders
  • Certain infections
  • Some medications
  • Transfusion-related complications
  • Other diseases affecting red blood cells

The National Heart, Lung, and Blood Institute notes that anemia may result from insufficient red blood cell production, excessive blood loss or increased destruction of red blood cells.


Hidden Cause #1: Vitamin B12 Deficiency

Vitamin B12 is essential for healthy blood cell formation as well as normal neurological function.

A person can develop B12-deficiency anemia because they do not consume enough B12, but inadequate intake is not the only explanation.

The body may also have difficulty absorbing vitamin B12.

Potential causes include:

  • Pernicious anemia
  • Certain gastrointestinal disorders
  • Crohn's disease
  • Ulcerative colitis
  • Previous stomach or intestinal surgery
  • Some medications
  • Problems affecting the stomach or intestines
  • Certain autoimmune conditions

Vitamin B12 deficiency can produce typical anemia symptoms such as tiredness, weakness, dizziness and shortness of breath. However, it may also cause neurological symptoms including tingling, difficulty walking, memory problems, confusion or changes in mood.

Why this matters

If a person assumes that every low hemoglobin result is caused by iron deficiency, a B12 deficiency may be missed.

In such cases, the treatment needs to address the B12 deficiency and, importantly, determine why the vitamin is deficient.


Hidden Cause #2: Folate Deficiency

Folate, also known as vitamin B9, plays an important role in producing healthy red blood cells.

Low folate levels can occur because of:

  • Poor dietary intake
  • Increased nutritional requirements
  • Certain gastrointestinal conditions
  • Alcohol-related nutritional problems
  • Some medications
  • Problems with absorption

Folate deficiency may lead to a type of anemia in which red blood cells are abnormally large.

Because B12 and folate deficiencies can produce similar blood-test patterns, doctors may evaluate both when investigating unexplained anemia.


Hidden Cause #3: Chronic Kidney Disease

The kidneys do more than filter waste from the blood.

They also produce erythropoietin (EPO), a hormone that signals the bone marrow to produce red blood cells.

When kidney function becomes impaired, the kidneys may produce less EPO. As a result, the bone marrow receives a weaker signal to make red blood cells.

This can contribute to anemia.

Anemia associated with chronic kidney disease often develops gradually and may initially produce few symptoms. As it becomes more significant, patients may experience fatigue, weakness, shortness of breath, dizziness or difficulty concentrating.

Importantly, anemia in kidney disease can have multiple causes at the same time, including inflammation, nutritional deficiencies and blood loss.

Therefore, treating it may require more than simply prescribing iron.


Hidden Cause #4: Chronic Inflammation

Anemia can occur in people living with long-term inflammatory conditions.

This is commonly called anemia of inflammation or anemia of chronic disease.

Conditions associated with this type of anemia include:

  • Rheumatoid arthritis
  • Lupus
  • Chronic infections
  • Inflammatory bowel disease
  • Chronic kidney disease
  • Cancer
  • Other long-term inflammatory disorders

One important feature is that the body may have iron stored in its tissues while having difficulty making that iron available for red blood cell production.

In other words, the problem may not simply be "not enough iron."

The problem may be that the body is unable to use its stored iron effectively because of inflammatory changes.

NIDDK notes that chronic inflammation can alter iron handling, reduce EPO production and affect the bone marrow's response to EPO.


Hidden Cause #5: Autoimmune Diseases

The immune system normally protects the body from infections.

In autoimmune disease, however, the immune system can mistakenly attack the body's own tissues.

Some autoimmune diseases can contribute to anemia through chronic inflammation.

In other situations, the immune system may directly attack red blood cells, causing autoimmune hemolytic anemia.

Possible clues may include:

  • Rapidly falling hemoglobin
  • Jaundice
  • Dark urine
  • Unusual fatigue
  • Enlarged spleen
  • Recurrent episodes of anemia

This type of anemia requires a different diagnostic and treatment approach from simple nutritional anemia.


Hidden Cause #6: Hemolytic Anemia

Normally, red blood cells circulate for approximately 120 days before being removed from the bloodstream.

In hemolytic anemia, red blood cells are destroyed faster than the body can replace them.

This is known as hemolysis.

Potential causes include:

  • Autoimmune disorders
  • Inherited blood disorders
  • Certain infections
  • Some medications
  • Transfusion-related complications
  • Other disorders affecting red blood cells

Doctors may look for evidence of increased red blood cell destruction through tests such as reticulocyte count, bilirubin, LDH, haptoglobin and peripheral blood smear, depending on the clinical situation.

The NHLBI notes that hemolytic anemia may be mild or severe and can sometimes require medicines, transfusion or other specialist treatment depending on its cause.


Hidden Cause #7: Thalassemia and Other Inherited Blood Disorders

Not every patient with small red blood cells has iron deficiency.

Inherited disorders such as thalassemia can cause microcytic anemia and may sometimes be mistaken for iron deficiency.

This is particularly important in patients who:

  • Have had anemia for many years
  • Have a family history of anemia
  • Have normal or relatively preserved iron stores
  • Have abnormal red blood cell indices
  • Have required repeated evaluations for unexplained anemia

Thalassemia and other inherited blood disorders require appropriate hematological evaluation rather than automatically increasing iron intake.

Taking unnecessary iron when iron stores are already adequate is not an appropriate strategy.


Hidden Cause #8: Blood Loss You Cannot See

Some bleeding is obvious.

Other bleeding can remain hidden for months.

For example, gastrointestinal bleeding may occur because of:

  • Peptic ulcers
  • Gastritis
  • Polyps
  • Inflammatory bowel disease
  • Certain medications
  • Gastrointestinal cancers
  • Other gastrointestinal conditions

A person may not notice visible blood in the stool but may gradually lose enough blood to develop anemia.

In adults with unexplained iron-deficiency anemia, doctors may therefore investigate possible sources of blood loss rather than simply prescribing iron indefinitely.

Heavy menstrual bleeding is another important cause of blood loss, particularly in women.

The NHLBI identifies menstrual and gastrointestinal bleeding among important causes of anemia.


Hidden Cause #9: Bone Marrow Disorders

The bone marrow is the body's blood-cell production centre.

It produces:

  • Red blood cells
  • White blood cells
  • Platelets

When a disorder affects the bone marrow, production of one or more blood cell types may become abnormal.

This can result in anemia that does not respond as expected to routine nutritional treatment.

Bone marrow disorders can include conditions such as:

  • Myelodysplastic syndromes
  • Aplastic anemia
  • Bone marrow failure disorders
  • Leukemia
  • Other hematological diseases

A particularly important warning sign is when anemia occurs together with abnormalities in other blood-cell counts.

For example:

Low hemoglobin + low white blood cells + low platelets

may require a more detailed hematological evaluation.

This is one reason persistent unexplained anemia should not always be treated as a simple nutritional deficiency.


Hidden Cause #10: Blood Cancers and Other Serious Conditions

Anemia can sometimes accompany blood cancers and other serious diseases.

Cancer may contribute to anemia through:

  • Chronic inflammation
  • Blood loss
  • Nutritional problems
  • Effects on bone marrow
  • Kidney-related changes
  • Treatment-related effects

The presence of anemia does not mean that a person has cancer.

However, persistent unexplained anemia, particularly when accompanied by other abnormal blood counts or systemic symptoms, deserves appropriate medical evaluation.

This is where specialist hematology becomes particularly important.

A hematologist can determine whether the anemia is nutritional, inflammatory, inherited, immune-related, marrow-related or associated with another underlying condition.


What Symptoms Should You Never Ignore?

Mild anemia can sometimes produce few symptoms.

As anemia becomes more significant, symptoms may include:

  • Persistent fatigue
  • Weakness
  • Shortness of breath
  • Dizziness
  • Headaches
  • Pale skin
  • Reduced exercise tolerance
  • Fast heartbeat
  • Difficulty concentrating
  • Chest discomfort in severe cases

Some symptoms may also provide clues about the underlying cause.

For example:

Anemia + tingling or numbness

May raise suspicion of vitamin B12 deficiency.

Anemia + kidney disease

May suggest anemia related to reduced kidney function.

Anemia + jaundice or dark urine

May indicate increased red blood cell destruction.

Anemia + abnormal white cells or platelets

May require investigation of the bone marrow.

Anemia + chronic inflammation

May be associated with an underlying inflammatory or autoimmune condition.

Anemia + unexplained weight loss or persistent fever

Requires medical evaluation for a broader range of possible causes.

These combinations do not establish a diagnosis by themselves, but they can help guide further testing.


How Is Unexplained Anemia Diagnosed?

A complete blood count, commonly called a CBC, is usually one of the first investigations.

However, a CBC is only the beginning.

A hematologist may consider:

1. Complete Blood Count

A CBC provides information about:

  • Hemoglobin
  • Red blood cell count
  • Mean corpuscular volume (MCV)
  • White blood cells
  • Platelets

The MCV can help classify anemia as:

  • Microcytic
  • Normocytic
  • Macrocytic

2. Iron Studies

Depending on the situation, testing may include:

  • Ferritin
  • Serum iron
  • Transferrin
  • Total iron-binding capacity
  • Transferrin saturation

3. Vitamin Testing

Doctors may assess:

  • Vitamin B12
  • Folate

4. Reticulocyte Count

Reticulocytes are young red blood cells.

The reticulocyte count can help doctors determine whether the bone marrow is responding appropriately to anemia.

5. Peripheral Blood Smear

A blood smear allows specialists to examine the appearance of blood cells under a microscope.

It can provide important clues in certain types of anemia and blood disorders.

6. Kidney and Liver Tests

Kidney and liver function may be evaluated when the clinical picture suggests an underlying systemic condition.

7. Tests for Hemolysis

Depending on the suspected diagnosis, doctors may evaluate:

  • Bilirubin
  • LDH
  • Haptoglobin
  • Reticulocyte count
  • Direct antiglobulin testing

8. Additional Specialized Testing

Depending on the findings, further investigations could include:

  • Hemoglobin electrophoresis
  • Autoimmune testing
  • Gastrointestinal evaluation
  • Genetic testing
  • Bone marrow examination
  • Imaging
  • Other specialized hematology investigations

NIDDK notes that evaluation of anemia may include medical history, physical examination, CBC, red-cell indices, reticulocyte testing, iron studies and vitamin B12/folate testing, with further investigation or hematology referral when the cause remains unclear.


Why the MCV Matters in Anemia

One of the simplest but most useful clues in a CBC is the mean corpuscular volume (MCV).

It describes the average size of red blood cells.

Microcytic anemia

Red blood cells are smaller than normal.

Possible causes include:

  • Iron deficiency
  • Thalassemia
  • Some chronic inflammatory conditions
  • Certain less common disorders

Normocytic anemia

Red blood cells are generally normal in size.

Possible causes include:

  • Chronic kidney disease
  • Chronic inflammation
  • Acute blood loss
  • Hemolysis
  • Bone marrow disorders

Macrocytic anemia

Red blood cells are larger than normal.

Possible causes include:

  • Vitamin B12 deficiency
  • Folate deficiency
  • Alcohol-related effects
  • Certain medications
  • Liver disease
  • Some bone marrow disorders

MCV does not diagnose the cause by itself, but it helps doctors decide what to investigate next.


Why Taking Iron Without a Diagnosis Can Be a Mistake

Iron supplements are valuable when iron deficiency is confirmed or strongly suspected.

But iron is not a universal treatment for every type of anemia.

If anemia is caused by:

  • Vitamin B12 deficiency
  • Folate deficiency
  • Kidney disease
  • Chronic inflammation
  • Hemolysis
  • Thalassemia
  • Bone marrow disease

then simply taking more iron may not correct the underlying problem.

In some patients, unnecessary supplementation can also complicate the clinical picture.

The better approach is:

Find the cause → confirm the diagnosis → treat the underlying problem.


When Should You See a Hematologist?

You may benefit from specialist evaluation when:

  • Hemoglobin remains low despite treatment
  • Anemia keeps returning
  • Iron levels are normal but hemoglobin remains low
  • There is anemia without an obvious cause
  • Several blood-cell counts are abnormal
  • There is a family history of inherited blood disorders
  • There are signs of hemolysis
  • There is unexplained weight loss, fever or night sweats
  • There is suspected bone marrow disease
  • You have a known blood disorder
  • You have anemia associated with cancer or cancer treatment
  • Your doctor recommends a bone marrow evaluation

A hematologist specialises in disorders affecting blood cells, bone marrow and the blood-forming system.


Dr. Rahul Bhargava: Specialist Hematology Care at Fortis Gurugram

For patients with unexplained or complex blood disorders, choosing the right hematology specialist can make a significant difference in the diagnostic journey.

Dr. Rahul Bhargava is Principal Director & Chief – Hematology, Hemato-Oncology & Bone Marrow Transplant at Fortis Memorial Research Institute (FMRI), Gurugram.

According to Fortis Healthcare, Dr. Bhargava has 16 years of experience and holds MBBS, MD and DM qualifications. His clinical areas include hematology, hemato-oncology and hematology/BMT. Fortis describes his experience in managing complex blood disorders including leukemia, lymphoma and thalassemia, along with extensive experience in bone marrow transplantation.

His role is particularly relevant for patients whose anemia may be part of a more complicated hematological condition rather than an isolated nutritional deficiency.

For international patients, specialist evaluation can help answer an important question:

Is the low hemoglobin really an iron problem—or is something else happening inside the blood or bone marrow?


Fortis Memorial Research Institute, Gurugram: Advanced Hematology Care

Fortis Memorial Research Institute in Gurugram has a dedicated hematology and bone marrow transplantation service.

Fortis lists Dr. Rahul Bhargava as Principal Director & Chief of Hematology, Hemato-Oncology & Bone Marrow Transplant at FMRI Gurugram. The hospital's hematology services include specialist care for blood disorders and hematological malignancies.

The hospital also has access to multidisciplinary expertise across hematology, hemato-oncology, transplantation and related specialties.

In June 2026, Fortis Gurugram announced the launch of its Centre of Excellence for Myeloma & Lymphoma, bringing together advanced diagnostics, genomics, bone marrow transplantation, cellular therapies, precision medicine and multidisciplinary blood-cancer care. Dr. Rahul Bhargava was among the experts involved in the initiative.

While most cases of anemia are not blood cancer, the availability of advanced hematology expertise is particularly valuable when routine investigations fail to explain persistent or complex abnormalities.


Why International Patients Consider India for Hematology Treatment

Patients travelling from Africa, the Middle East, Central Asia, Southeast Asia and other regions may consider India when they require specialist evaluation for complex blood disorders.

India has developed advanced centres for:

  • Hematology
  • Hemato-oncology
  • Bone marrow transplantation
  • Cellular therapy
  • Blood cancer treatment
  • Genetic and molecular diagnostics
  • Multidisciplinary cancer care

Another important advantage is the ability to coordinate multiple diagnostic and treatment services within a single healthcare ecosystem.

For an international patient, this can reduce unnecessary delays between consultation, diagnostic testing and treatment planning.


Why Choose Dr. Rahul Bhargava for Complex Blood Disorders?

Patients seeking specialist hematology care may consider Dr. Rahul Bhargava when they require evaluation for complex blood-related conditions.

His profile at Fortis highlights experience in:

  • Hematology
  • Hemato-oncology
  • Bone marrow transplantation
  • Leukemia
  • Lymphoma
  • Thalassemia
  • Complex blood disorders

Fortis lists him as Principal Director & Chief – Hematology, Hemato-Oncology & Bone Marrow Transplant at FMRI Gurugram.

For a patient with persistent anemia, the key benefit of seeing a hematologist is not simply receiving another prescription.

It is understanding why the anemia exists.


What International Patients Should Bring to Their Consultation

If you are travelling to India for anemia or a suspected blood disorder, bring as much previous medical information as possible.

Useful documents include:

  • Recent CBC reports
  • Previous CBC reports
  • Hemoglobin history
  • Ferritin and iron studies
  • Vitamin B12 and folate results
  • Kidney function reports
  • Liver function tests
  • Peripheral smear reports
  • Reticulocyte count
  • Previous bone marrow reports
  • Genetic testing, if available
  • Previous imaging
  • Medication list
  • Previous treatment records
  • Blood transfusion history
  • Family history of blood disorders

A timeline of previous hemoglobin values can also be extremely useful.

For example:

Hemoglobin 9.8 → 9.2 → 8.7 → 9.0 g/dL

is more informative than seeing only one isolated result.


Medical Treatment for Anemia Depends on the Cause

There is no single treatment for anemia.

Treatment may include:

Iron replacement

Used when iron deficiency is confirmed or clinically indicated.

Vitamin B12 replacement

Used when B12 deficiency is identified.

Folate supplementation

Used for appropriate folate deficiency.

Treatment of chronic disease

When anemia is caused by inflammation, autoimmune disease, infection or another chronic condition, treating the underlying disease may improve the anemia.

Kidney-related treatment

Patients with anemia related to chronic kidney disease may require a combination of approaches depending on their kidney function, iron status and overall clinical condition.

Treatment for hemolysis

Management depends on why red blood cells are being destroyed.

Blood transfusion

May be considered in selected patients with severe or symptomatic anemia, depending on the clinical situation.

Bone marrow-directed treatment

If anemia is caused by a bone marrow disorder, treatment must be directed at the specific marrow condition.

This is why diagnosis comes before treatment.


Can Anemia Be Prevented?

Some forms of anemia can be prevented or reduced by addressing nutritional deficiencies and underlying health problems.

However, not every type can be prevented.

You can reduce your risk by:

  • Maintaining a balanced diet
  • Addressing nutritional deficiencies
  • Managing chronic diseases
  • Seeking evaluation for persistent symptoms
  • Investigating unexplained blood loss
  • Following recommended screening
  • Avoiding unnecessary self-medication
  • Seeking specialist advice when anemia persists

Inherited blood disorders cannot simply be prevented through diet, but appropriate diagnosis and genetic counselling may help families understand their risks.


When Low Hemoglobin Is More Than "Just Anemia"

One of the biggest mistakes patients can make is focusing only on the hemoglobin number.

For example:

Hemoglobin is low → take iron → repeat test.

Sometimes this works.

But if the hemoglobin remains low, the next question should be:

Why isn't it improving?

That question can open the door to a more complete investigation.

The answer may involve:

  • Nutrient absorption
  • Kidney function
  • Chronic inflammation
  • Autoimmune disease
  • Genetic factors
  • Blood loss
  • Red blood cell destruction
  • Bone marrow function
  • Another underlying medical condition

A persistent abnormal blood count deserves an explanation.


Frequently Asked Questions About Anemia

1. Is every anemia caused by iron deficiency?

No. Iron deficiency is common, but anemia can also result from vitamin B12 or folate deficiency, chronic kidney disease, inflammation, blood loss, hemolysis, inherited disorders and bone marrow conditions.

2. Can anemia occur when iron levels are normal?

Yes. Anemia can occur for many reasons unrelated to iron deficiency, including B12 deficiency, kidney disease, inflammation and bone marrow disorders.

3. Why does anemia keep coming back?

Recurrent anemia may indicate that the underlying cause has not been identified or treated. Ongoing blood loss, chronic disease, nutritional absorption problems or inherited disorders are among the possibilities.

4. Should I take iron if my hemoglobin is low?

Do not assume that low hemoglobin automatically means you need iron. Iron studies and the overall clinical picture should guide treatment.

5. Can vitamin B12 deficiency cause neurological symptoms?

Yes. B12 deficiency can cause neurological symptoms such as tingling, difficulty walking, confusion and memory problems in addition to anemia symptoms.

6. Can kidney disease cause anemia?

Yes. Damaged kidneys may produce less erythropoietin, reducing the signal to the bone marrow to make red blood cells.

7. What is anemia of chronic disease?

It is anemia associated with chronic inflammation or long-term diseases. The body may have stored iron but have difficulty using it effectively for red blood cell production.

8. What is hemolytic anemia?

Hemolytic anemia occurs when red blood cells are destroyed faster than the body can replace them.

9. Can anemia be a sign of leukemia or lymphoma?

Anemia can occur with blood cancers, but anemia alone does not mean a person has leukemia or lymphoma. Persistent or unexplained anemia should be evaluated in its broader clinical context.

10. When should I see a hematologist?

Consider specialist evaluation when anemia persists, repeatedly returns, does not respond as expected to treatment, occurs with other abnormal blood counts or has no clear cause.

11. What tests are usually performed for unexplained anemia?

Depending on the patient, doctors may order CBC, red-cell indices, iron studies, vitamin B12 and folate, reticulocyte count, peripheral smear, kidney and liver tests and tests for hemolysis. Additional investigations may be needed based on the findings.

12. Can children have anemia from causes other than iron deficiency?

Yes. Children can develop anemia because of nutritional deficiencies, inherited blood disorders, chronic disease, hemolysis and other conditions. Persistent or unexplained anemia in a child should be evaluated by an appropriate specialist.

13. Can thalassemia be mistaken for iron-deficiency anemia?

Yes. Some forms of thalassemia can cause small red blood cells and may resemble iron deficiency on a basic CBC. Additional testing may be needed.

14. Does anemia always cause symptoms?

No. Mild or slowly developing anemia may cause few symptoms, while more significant anemia may cause fatigue, weakness, breathlessness, dizziness or other symptoms.

15. Can anemia be treated permanently?

That depends on its cause. Some forms, such as nutritional deficiencies, may resolve once the underlying deficiency is corrected. Other forms related to chronic, inherited or bone marrow conditions may require long-term management.


Final Takeaway: Don't Treat the Number—Find the Cause

Anemia is common, but "low hemoglobin" is not a diagnosis.

Iron deficiency is only one piece of the puzzle.

If your hemoglobin remains low despite iron treatment, if your iron levels are normal, or if anemia is accompanied by other abnormal blood counts or unexplained symptoms, it may be time for a more detailed hematological evaluation.

The right approach is to identify whether the body is:

not producing enough red blood cells, losing blood, or destroying red blood cells too quickly.

For patients with persistent or complex blood abnormalities, consultation with an experienced hematologist can help uncover the underlying cause and guide appropriate treatment.

Dr. Rahul Bhargava, Principal Director & Chief – Hematology, Hemato-Oncology & Bone Marrow Transplant at Fortis Memorial Research Institute, Gurugram, is an experienced specialist in complex hematological disorders, hemato-oncology and bone marrow transplantation.

For international patients considering treatment in India, a specialist evaluation can be coordinated with the appropriate diagnostic investigations and treatment planning based on the individual medical history.

Do not ignore persistent anemia. And do not assume every low hemoglobin result is simply an iron deficiency.
