In the case of anaemia, the amount of haemoglobin in the blood becomes very less than normal (5-9 grams per 100 ml of blood), which reduces the ability of the body’s cells to take up oxygen. As a result, the cells do not get enough oxygen. It is caused by an insufficient supply of one or more nutritional elements like iron, protein, vitamin B12, folic acid, vitamin B6, and vitamin C. in India, it poses a huge health burden. Iron deficiency anaemia was the leading cause of years lived with disability among young adult girls. In India, 86.0% of girls are suffering from anaemia in 2019-20 and Bihar, 63.6% of girls are suffering from anaemia according to NFHS. The main reason for the study is that India has the largest number of anaemia in girls. Anaemia is considered an important health problem because of the adverse effects on mental and physical development during a girl’s development. Many nutritional surveys see that most girls do not take sufficient nutritional supplements. Most of the girls are not aware that they are affected by anaemia which was a reason increasing anaemia number. They are headed for malnutrition.
