Anemia - Symptoms, Causes & Treatment
Anemia is a condition where the blood lacks enough healthy red blood cells or hemoglobin to carry adequate oxygen to the body's tissues, causing fatigue, weakness, and other symptoms.
Overview
Anemia is one of the most common blood disorders, affecting approximately 1.6 billion people globally. In India, it is particularly prevalent, affecting about 50% of women and 23% of men.
Iron deficiency anemia is the most common type, but there are many forms including vitamin B12 deficiency, folate deficiency, and anemia of chronic disease. Proper diagnosis of the type is important for effective treatment.
Symptoms of Anemia
- FatiguePrimary
Fatigue is a feeling of persistent tiredness or exhaustion that does not improve with rest. It can be physical, mental, or both, and may indicate an underlying health condition.
- DizzinessPrimary
Dizziness is a feeling of lightheadedness, unsteadiness, or a sensation that the room is spinning. It is a common symptom that can have many underlying causes.
- Headache
A headache is pain or discomfort in the head, scalp, or neck. Most headaches are not serious and can be treated with lifestyle changes and medication.
- Shortness of Breath
Shortness of breath (dyspnea) is a feeling of not being able to get enough air, or difficulty breathing. It can be caused by various heart, lung, or other conditions.
