Introduction:
Marasmus is a severe form of malnutrition that results from a deficiency of both protein and calories in the diet. It is a life-threatening condition that primarily affects children in developing countries who do not have access to adequate food and clean water.

Cause:
The main cause of marasmus is a deficiency of both protein and calories in the diet. When the body does not receive enough protein and calories, it begins to break down muscle tissue and other organs to provide energy. Over time, this can lead to severe wasting of the body, which is a hallmark of marasmus.

Deficiency:
Marasmus is caused due to deficiency of both carbohydrate and protein. Carbohydrates are the primary source of energy for the body, while proteins are essential for the growth and repair of tissues. When the body does not receive enough of these nutrients, it cannot function properly, and a range of symptoms can occur.

Symptoms:
The symptoms of marasmus include severe wasting of the body, muscle atrophy, weakness, and lethargy. Children with marasmus may also have a weak immune system, making them more susceptible to infections and other illnesses. In severe cases, marasmus can lead to death.

Treatment:
The treatment for marasmus involves providing the body with adequate amounts of protein and calories through a balanced diet. In severe cases, hospitalization may be necessary to provide the child with proper nutrition and medical care. Once the child's condition improves, a long-term plan for proper nutrition and follow-up care is essential to prevent the recurrence of marasmus.

Conclusion:
Marasmus is a severe form of malnutrition that primarily affects children in developing countries. It is caused by a deficiency of both protein and calories in the diet and can lead to severe wasting of the body, weakness, and lethargy. Treatment involves providing the body with proper nutrition and medical care, followed by a long-term plan for prevention.
