What impact does protein deficiency have on pulmonary edema?

• A. It decreases the risk of cardiopulmonary diseases
• B. It has no effect on edema
• C. It increases the risk due to decreased oncotic pressure
• D. It promotes healthy lung function

Answer: (C)

The impact of protein deficiency on pulmonary edema is closely linked to the concept of oncotic pressure, which is the pressure exerted by proteins in the blood plasma that helps to keep fluid balanced within the vascular system. Protein deficiency, particularly a lack of albumin and other plasma proteins, leads to a reduction in oncotic pressure. This decrease impairs the ability of blood vessels to retain fluid, resulting in fluid leaking into the surrounding tissues and contributing to the development of conditions like pulmonary edema. When the oncotic pressure is insufficient, the fluid accumulates within the lungs, making it difficult for the respiratory system to function effectively. This can exacerbate respiratory diseases and can be particularly detrimental to the elderly, who may already be at higher risk for pulmonary complications. Thus, protein deficiency is associated with an increased risk of pulmonary edema due to this loss of oncotic pressure, making the option highlighting this relationship the correct choice.
