All are true about marasmus except: March 2011
**Core Concept**
Marasmus is a form of severe malnutrition characterized by energy deficiency, leading to muscle wasting and loss of body fat. It is one of the two main forms of malnutrition, the other being kwashiorkor. Marasmus is typically seen in children who are not consuming enough calories to meet their energy needs.
**Why the Correct Answer is Right**
Marasmus is caused by a severe deficiency of energy, leading to the breakdown of muscle tissue and loss of body fat. This condition is often seen in children who have limited access to food and are not consuming enough calories to meet their energy needs. The energy deficiency leads to a catabolic state, where the body breaks down its own tissues to meet its energy requirements. This results in muscle wasting, edema, and a range of other systemic complications.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because marasmus is indeed characterized by a severe deficiency of energy, leading to muscle wasting and loss of body fat.
**Option B:** This option is incorrect because marasmus is a form of malnutrition that is primarily caused by energy deficiency, not necessarily by a lack of protein.
**Option C:** This option is incorrect because marasmus is typically seen in children who are not consuming enough calories to meet their energy needs, not necessarily in adults.
**Clinical Pearl / High-Yield Fact**
Marasmus is often seen in children who are experiencing famine or food insecurity, and it is essential to provide these children with adequate nutrition to prevent the development of this condition.
**Correct Answer:** B.
