Which factor is directly linked to poor wound healing in patients?

Low protein intake is directly linked to poor wound healing in patients because proteins are vital for various physiological processes, including the repair and regeneration of tissues. Protein is a crucial building block for the formation of new cells, which are necessary for healing wounds. When a patient has insufficient protein in their diet, their body may struggle to produce collagen and other essential components needed for tissue repair, resulting in delayed healing and increased risk of complications.

While high blood pressure, excessive sugar consumption, and dehydration can also impact overall health and may contribute to slower healing, they do not have the same direct relationship to the specific mechanisms of wound healing as protein intake does. Protein not only plays a critical role in cell growth and repair but also helps in the functioning of the immune system, which can influence the healing process.
