Overview

Anemia is not just “low iron” — the cause matters.

Anemia means your blood does not have enough healthy red blood cells or hemoglobin to carry oxygen efficiently. This can leave you feeling tired, weak, dizzy, short of breath or unable to exercise as usual.

Many people assume anemia is always caused by low iron, but anemia can also be related to vitamin B12 or folate deficiency, chronic inflammation, heavy menstrual bleeding, digestive blood loss, kidney disease, poor absorption or other medical conditions.

At Apgujeong Hana Clinic, we evaluate anemia by looking beyond one number. We review your CBC, iron stores, symptoms, diet, medication history, menstrual history and possible digestive causes to build a clear treatment and follow-up plan.

CBC & Hemoglobin Review
We review hemoglobin, red blood cell size, hematocrit and other CBC markers to understand the pattern of anemia.
πŸ”¬
Iron, Ferritin & Nutrient Testing
Testing may include ferritin, iron studies, vitamin B12, folate and related markers based on your symptoms and CBC pattern.
πŸ”Ž
Cause-Focused Assessment
We look for why anemia happened — diet, bleeding, absorption problems, chronic disease or other medical causes.
πŸ’¬
English Explanation
Your results, possible causes and treatment options are explained clearly in English for international patients.
Low hemoglobin should be explained, not ignored.
Anemia may be mild, but it can also be a sign of iron deficiency, hidden blood loss, vitamin deficiency or another condition that needs follow-up. Early evaluation helps prevent symptoms from becoming chronic.
Fatigue
Dizziness
Low ferritin
Abnormal CBC
When To Check

Symptoms and situations that may need anemia evaluation.

Anemia can develop gradually, so symptoms are often mistaken for stress, poor sleep or overwork. Evaluation is especially helpful if symptoms are persistent, new, worsening or connected with abnormal blood test results.

😴
Fatigue & Low Energy
Persistent tiredness, reduced stamina, weakness, brain fog or feeling exhausted despite normal sleep.
πŸ’¨
Shortness of Breath
Breathlessness during stairs, walking, exercise or daily activities that previously felt easy.
πŸŒ€
Dizziness or Lightheadedness
Feeling faint, dizzy on standing, reduced concentration or frequent headaches with low blood counts.
❀️
Palpitations
Fast heartbeat, pounding heartbeat or chest discomfort can occur when the body is working harder to deliver oxygen.
πŸ“‹
Abnormal Health Checkup Result
Low hemoglobin, low hematocrit, small red blood cells, high MCV, low ferritin or abnormal CBC markers.
🌿
Diet or Absorption Concerns
Vegetarian or vegan diet, low iron intake, stomach surgery history, digestive symptoms or long-term acid medication use.
Testing Approach

We check the pattern of anemia — then look for the cause.

The first step is usually a complete blood count. A CBC helps show whether hemoglobin is low and whether red blood cells are small, normal-sized or large. This pattern helps guide the next tests.

Iron deficiency anemia often requires iron studies such as ferritin, serum iron and transferrin saturation. If red blood cells are larger than expected, vitamin B12 and folate testing may be important.

In some patients, anemia is not simply nutritional. We may consider inflammation markers, kidney function, liver function, thyroid function, stool blood testing or gastroenterology referral depending on your results and history.

Possible Tests

Blood tests commonly used for anemia workup.

βœ“ Complete blood count / CBC
βœ“ Hemoglobin and hematocrit
βœ“ MCV / red blood cell size
βœ“ Ferritin and iron studies
βœ“ Vitamin B12 level
βœ“ Folate level
βœ“ Inflammation markers
βœ“ Kidney and liver function
βœ“ Thyroid function if indicated
βœ“ Stool blood test if needed
Possible Causes

Common reasons adults develop anemia or low ferritin.

Finding the cause is the most important part of anemia care. Treatment is different for iron deficiency, B12 deficiency, chronic inflammation or blood loss — so we avoid guessing and use test results to guide the plan.

🩸
Iron Deficiency
Low iron stores may come from low intake, poor absorption, heavy menstrual bleeding or chronic blood loss.
🌱
Vitamin B12 or Folate Deficiency
Deficiency may be related to diet, absorption problems, stomach conditions or certain long-term medications.
♀️
Heavy Periods
Recurrent heavy menstrual bleeding is a common reason for low ferritin and iron deficiency in women.
πŸ”¬
Digestive Blood Loss
In some adults, anemia may be related to stomach or intestinal bleeding that needs further evaluation.
πŸ”₯
Chronic Inflammation
Long-term inflammatory conditions can affect how the body uses and stores iron.
🧬
Other Blood Conditions
Less common causes include inherited blood disorders, bone marrow issues or red blood cell breakdown.

FAQ

The basic test is usually a complete blood count, or CBC. Depending on the result, your doctor may also check ferritin, iron studies, vitamin B12, folate, inflammation markers, kidney function, liver function or stool blood testing.
No. Iron deficiency is common, but anemia can also be caused by vitamin B12 or folate deficiency, chronic inflammation, kidney disease, digestive blood loss, heavy menstrual bleeding, medication effects or other blood conditions.
Some patients feel tired, weak or less able to exercise when iron stores are low, even before hemoglobin becomes clearly low. Your doctor can interpret ferritin together with CBC, symptoms and other iron markers.
Not everyone needs endoscopy. However, if iron deficiency anemia suggests possible digestive blood loss, or if there are symptoms such as black stool, weight loss, abdominal pain or persistent digestive issues, your doctor may recommend further gastroenterology evaluation.
