Anaemia

What is Anaemia? Anaemia is a common medical condition that affects millions of people worldwide. It occurs when the body does not have enough healthy red blood cells to carry oxygen to the tissues. Red blood cells contain a protein called hemoglobin, which binds to oxygen in the lungs and transports it to various parts of the body. When the level of hemoglobin is low, the body does not receive enough oxygen, leading to symptoms such as weakness, fatigue, and shortness of breath. Anaemia can be caused by various factors, including a lack of essential nutrients such as iron, vitamin B12, and folic acid. These nutrients are crucial for the production of red blood cells, and their deficiency can impair the body's ability to generate an adequate supply. In some cases, anemia may also be a result of an underlying medical condition or chronic disease. Types of Anaemia There are several different types of anemia, each with its own unique characteristics and challenges. One of the most c...
