Anemia is a common blood disorder that affects a significant portion of the global population. It occurs when the body lacks enough healthy red blood cells to carry sufficient oxygen to the tissues. The prevalence of anemia varies across different regions and populations.
Globally, anemia affects approximately 1.62 billion people, which accounts for around 24.8% of the world's population. This makes anemia a major public health concern.
In developing countries, anemia is more prevalent due to factors such as poor nutrition, limited access to healthcare, and higher rates of infectious diseases. It affects around 43% of children under the age of five, 38% of pregnant women, and 29% of non-pregnant women.
In developed countries, the prevalence of anemia is generally lower. However, certain populations may still be at risk, including infants, young children, pregnant women, and older adults. In the United States, for example, an estimated 5-6% of the population has anemia.
It is important to note that anemia can have serious health consequences if left untreated. It can lead to fatigue, weakness, impaired cognitive function, and increased risk of infections. Therefore, early detection, proper diagnosis, and appropriate treatment are crucial in managing this condition.
