Introduction
Anemia is one of the most common health conditions worldwide, especially among women. It occurs when the body does not have enough healthy red blood cells to carry oxygen to tissues. This makes a person feel weak, tired, and low in energy.
What Causes Anemia?
- Iron Deficiency: The most common cause, often due to heavy menstrual cycles or poor diet.
- Vitamin Deficiency: Lack of vitamin B12 or folate can also lead to anemia.
- Chronic Diseases: Conditions like kidney disease can affect red blood cell production.
- Genetic Causes: Some people inherit conditions like sickle-cell anemia.
Biology Behind Anemia
Red blood cells contain hemoglobin, a protein that binds oxygen. When there is not enough hemoglobin, tissues and organs do not get the oxygen they need. This is why people with anemia often feel tired or dizzy.
Symptoms of Anemia
- Fatigue and weakness
- Pale skin
- Shortness of breath
- Headaches and dizziness
- Cold hands and feet
How to Prevent Anemia?
The best way to prevent anemia is to eat a balanced diet with iron-rich foods like spinach, red meat, lentils, and fortified cereals. Doctors may also recommend iron supplements or vitamins when needed.
Conclusion
Anemia is not just a medical condition — it’s a biological problem at the level of red blood cells and hemoglobin. Understanding the biology helps us take care of health in daily life.
