کم خونی (kam-khooni) is the Persian word for anemia, a condition in which the blood does not have enough healthy red blood cells or hemoglobin to carry oxygen efficiently around the body. It commonly causes tiredness, pale skin and breathlessness. Anemia is diagnosed with a simple blood test and is usually treatable once the cause, most often iron deficiency, is identified.
Many of my patients and their families first hear the diagnosis in their own language, then search for reliable information in English. This guide explains what the term means and what to expect from assessment and treatment.
What Is کم خونی (Anemia)?
Healthy red blood cells contain hemoglobin, an iron-rich protein that picks up oxygen in the lungs and releases it to tissues. When hemoglobin falls below the normal range, organs receive less oxygen and the body has to work harder, especially the heart.
Doctors define anemia by the hemoglobin level. Widely used cut-offs are shown below.
| Group | Anemia if hemoglobin is below |
|---|---|
| Adult men | 13.0 g/dL |
| Non-pregnant adult women | 12.0 g/dL |
| Pregnant women | 11.0 g/dL |
| Children 6 months to 5 years | 11.0 g/dL |
Anemia is one of the most common medical conditions worldwide. Young children, women of reproductive age, pregnant women and older adults are affected most often.
Symptoms of Anemia
Mild anemia may cause no symptoms at all and is found only on a routine blood test. As it becomes more severe, or develops quickly, symptoms appear:
- Fatigue, low energy and difficulty concentrating
- Pale skin, pale inner eyelids or pale nail beds
- Shortness of breath on exertion
- A fast or irregular heartbeat
- Dizziness, headaches or light-headedness
- Cold hands and feet
- Brittle or spoon-shaped nails and cravings for ice or non-food items, which suggest iron deficiency
- Yellowish skin or eyes (jaundice), which can point to red cells being destroyed too quickly
In children, anemia can affect growth, learning and behavior. In older adults, it may worsen heart or lung disease and increase the risk of falls.
Main Causes and Types
Anemia is a sign of an underlying problem rather than a disease on its own. Causes fall into three groups: blood loss, reduced production of red blood cells, and increased destruction of red cells.
| Type | Common causes | Typical clue on blood tests |
|---|---|---|
| Iron deficiency anemia | Heavy periods, pregnancy, gut bleeding, low dietary iron | Small red cells, low ferritin |
| Vitamin B12 or folate deficiency | Diet, pernicious anemia, gut disease, some medicines | Large red cells |
| Anemia of chronic disease | Kidney disease, inflammation, infection, cancer | Normal or slightly small cells, normal or high ferritin |
| Hemolytic anemia | Autoimmune disease, inherited red cell defects, some drugs | Raised bilirubin and reticulocytes |
| Inherited hemoglobin disorders | Thalassemia, sickle cell disease | Abnormal hemoglobin studies |
| Marrow failure | Aplastic anemia, leukemia, myelodysplasia | Low counts of several cell types |
Thalassemia deserves a special mention for families of Iranian, Middle Eastern, Mediterranean and South Asian heritage, where carrier status is relatively common. Thalassemia trait can look like iron deficiency on a basic blood count, so iron should not be given without checking iron levels first.
How Anemia Is Diagnosed
The starting point is a complete blood count (CBC), which measures hemoglobin and hematocrit, red cell size (MCV) and the other blood cells. Depending on the results, a doctor may add:
- Iron studies, including ferritin, the best single measure of iron stores
- Vitamin B12 and folate levels
- Reticulocyte count, which shows whether the marrow is responding
- Blood film, looking at red cell shape under a microscope
- Hemoglobin electrophoresis to look for thalassemia or sickle cell disease
- Kidney and liver tests, and tests for bleeding in the gut when appropriate
If several blood counts are low, or the cause remains unclear, a bone marrow test may be needed to examine the bone marrow directly.
Treatment Options
Treatment depends on the cause:
- Iron deficiency: oral iron tablets, or intravenous iron if tablets are not tolerated or absorbed, plus finding and treating the source of iron loss.
- B12 deficiency: B12 injections or high-dose tablets; pernicious anemia usually needs lifelong treatment.
- Folate deficiency: folic acid tablets and dietary improvement.
- Anemia of chronic disease: controlling the underlying illness; in kidney disease, medicines that stimulate red cell production.
- Hemolytic anemia: depends on the cause, and may include steroids or stopping a triggering drug.
- Bone marrow disorders: specialist treatment, which may include transfusions, medicines, or stem cell transplantation.
Blood transfusion is reserved for severe or symptomatic anemia, or for significant bleeding.
Following Up on Treatment
Treatment is not finished when you start the tablets. I usually repeat the blood count after a few weeks to confirm hemoglobin is rising, then again once it has normalized. If the count does not improve as expected, that is a signal to look again at the diagnosis, check whether the medicine is being absorbed, or search for ongoing blood loss.
Side effects are worth mentioning to your doctor rather than stopping treatment. Iron tablets often cause constipation or stomach upset, and a change of dose, timing or preparation usually helps.
Complications and Prevention
Untreated anemia can cause severe fatigue, worsen heart conditions, and in severe cases contribute to heart failure. In pregnancy, it is linked with premature birth and low birth weight, and in children it can affect development.
Prevention focuses on the common causes:
- A diet with iron-rich foods such as meat, fish, lentils, beans and leafy greens
- Vitamin C-rich foods with meals to improve iron absorption
- Avoiding tea with meals, as it reduces iron absorption
- Iron and folic acid supplements in pregnancy when advised
- Carrier screening before pregnancy for families at risk of thalassemia
When to See a Doctor
See a doctor if you have tiredness that does not improve with rest, breathlessness, palpitations or pale skin. Seek urgent help for chest pain, fainting, black stools or vomiting blood.
Frequently Asked Questions
What does کم خونی mean in English?
It translates directly as “low blood” and is the Persian term for anemia. It refers to a low level of hemoglobin or red blood cells, not a low volume of blood.
Is anemia dangerous?
Mild anemia is usually not dangerous, but it should always be investigated because it can signal an underlying problem such as hidden bleeding. Severe anemia can strain the heart and needs prompt treatment.
How long does it take to recover from iron deficiency anemia?
Hemoglobin often begins to rise within a few weeks of starting iron. Doctors usually continue treatment for a few months after levels normalize to rebuild iron stores.
Can thalassemia trait be mistaken for iron deficiency?
Yes. Both cause small red blood cells. Checking ferritin and, when needed, hemoglobin electrophoresis tells them apart.
