What is a clinical manifestation of malnutrition related to skin health?

Skin breakdown or ulceration is a clinical manifestation of malnutrition related to skin health due to the body's impaired ability to repair and maintain skin integrity. Nutritional deficiencies, particularly in protein, vitamins, and minerals, can significantly weaken the skin’s structure and its healing processes. For example, inadequate protein levels lead to reduced collagen synthesis, which is vital for skin integrity and elasticity. Additionally, deficiencies in vitamins such as vitamin C can hinder the formation of new skin cells and impede wound healing. Consequently, individuals experiencing malnutrition may develop compromised skin that is more susceptible to breakdown, leading to ulceration and other skin issues.

In terms of the other choices, thickened skin does not typically result from malnutrition; rather, it can occur due to overgrowth conditions or pressure-related injuries. Increased hair growth is not a sign related to malnutrition; instead, malnutrition often leads to hair thinning and loss. Improved wound healing contradicts the effects of malnutrition, as adequate nutrition is essential for timely and effective healing processes.
