Marasmus is a severe form of malnutrition that occurs due to a deficiency in both protein and calories. This condition is most commonly observed in infants and young children, particularly in areas with inadequate nutrition. Marasmus is characterized by a significant loss of muscle mass and body fat, resulting in a very emaciated appearance.
Symptoms of Marasmus:
Causes of Marasmus:
Marasmus occurs due to an insufficient intake of protein and calories over an extended period. This deficiency leads to the body breaking down its own muscle and fat tissue to meet energy needs. The most common causes of Marasmus include:
Difference between Marasmus and Kwashiorkor:
While both conditions are caused by protein deficiency, they have distinct characteristics. Marasmus is primarily caused by both protein and calorie deficiency, leading to extreme weight loss, whereas Kwashiorkor results from protein deficiency alone, causing symptoms like edema (swelling), fatty liver, and changes in skin and hair color.
Treatment of Marasmus:
Marasmus requires medical intervention that includes providing the affected infant with sufficient calories, protein, and micronutrients to restore normal growth and development. Nutritional rehabilitation and gradual refeeding are key aspects of treatment. In severe cases, the infant may require hospital care, including intravenous fluids and nutrients.

Digestion can be defined as the process of breakdown of large, insoluble and complex food molecules into smaller ones for its absorption and circulation in the body. This process involves the usage of a variety of digestive fluids and enzymes, including saliva, mucus, bile and hydrochloric acid, among others.

The alimentary canal is mainly referred to as the pathway by which food enters our body and moves out through the anus after digestion. It is a tube-like structure that starts from the mouth and ends in the anus. The alimentary canal plays a primary role in human digestion and is also termed as the digestive tract.
Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract.
