Iron Deficiency Anemia

 

What Is Iron Deficiency Anemia?

Iron deficiency anemia occurs when the body doesn’t have enough healthy red blood cells or hemoglobin to carry oxygen to body tissues. This leads to general weakness and fatigue. The condition can range from mild to severe and may sometimes indicate an underlying health problem.

The Role of Red Blood Cells

Red blood cells contain a protein rich in iron called hemoglobin, which gives blood its red color. Hemoglobin enables red blood cells to transport oxygen from the lungs to all parts of the body and to carry carbon dioxide back to the lungs for exhalation. Without sufficient hemoglobin, the body’s organs and tissues receive less oxygen, causing fatigue and other symptoms.

Common Causes of Anemia

• Iron deficiency: The body can’t produce enough hemoglobin for red blood cells.

• Pregnancy: Women who don’t take iron and vitamin supplements are more likely to develop anemia.

• Blood loss: Heavy menstrual bleeding, ulcers, cancers, or prolonged use of painkillers like aspirin can lead to anemia.

• Vitamin deficiency: A diet lacking essential vitamins and nutrients can cause anemia.

• Chronic diseases: Conditions like cancer or HIV/AIDS can prevent the body from producing enough red blood cells.

• Inherited disorders: Sickle cell anemia and other genetic blood disorders can lead to chronic anemia.

Risk Factors

Several factors can increase your risk of developing anemia:

• Poor diet lacking in iron, vitamin B12, or folic acid

• Medical conditions that reduce nutrient absorption in the intestines

• Heavy menstrual bleeding

• Pregnancy without iron or folic acid supplements

• Chronic illnesses such as kidney disease, diabetes, or cancer

• Family history of hereditary anemia (e.g., sickle cell anemia)

• Age — people over 65 are more likely to develop anemia

Possible Complications

If left untreated, anemia can lead to:

• Severe fatigue: Making daily tasks difficult to perform.

• Pregnancy complications: Such as premature birth.

• Heart problems: Including irregular heartbeat, heart enlargement, or heart failure.

• Eat a balanced diet rich in iron, folic acid, and vitamin B12.

• Consult your doctor if you experience heavy menstrual bleeding.

• Seek medical advice immediately if symptoms of anemia appear.

• Maintain good hygiene to prevent infections.
