Anemia is a condition where there is a shortage of red blood cells or a decrease in the amount of hemoglobin in the blood. Red blood cells and hemoglobin are crucial for carrying oxygen from the lungs to the rest of the body. When someone has anemia, they may feel tired or weak because their body is not getting enough oxygen. Other symptoms can include pale skin, shortness of breath, dizziness, and cold hands and feet. Anemia can be caused by various factors, such as blood loss, not enough production of red blood cells, or loss or damage to red blood cells. Treatment depends on the underlying cause and may involve iron supplements, changes in diet, medications, or addressing any underlying health conditions contributing to the anemia.
