What is the primary consequence of marasmus in infants?

Marasmus is a form of severe malnutrition that occurs primarily in infants and young children, typically caused by a deficiency in calories and protein. The primary consequence of this condition is malnutrition, which leads to significant weight loss and a decrease in muscle mass and body fat. Infants with marasmus appear very thin and frail, and their growth is severely stunted, impacting their physical and cognitive development.

In the context of marasmus, other choices like severe dehydration, obesity, and gastroenteritis do not accurately represent the primary outcome of this condition. Severe dehydration can occur in various health conditions, but it is not specific to marasmus. Obesity is characterized by an excess of body fat, which is the opposite of what occurs in marasmus. Gastroenteritis refers to inflammation of the stomach and intestines, which can lead to diarrhea and vomiting, but it is not a direct consequence of marasmus. Instead, malnutrition is at the core of the condition, highlighting the critical need for adequate nutrition during early stages of life.
