Which of the following is a known cause of hypoalbuminemia?

Hypoalbuminemia, defined as low levels of albumin in the blood, can occur due to various reasons, but starvation is a well-established cause. During periods of starvation, the body begins to break down its own proteins, leading to decreased synthesis of albumin, as the amino acids necessary for its production become limited. Additionally, inadequate nutritional intake fails to meet the body’s protein and caloric needs, further contributing to decreased albumin production in the liver.

In contrast, while obesity, hypertension, and hyperlipidemia can influence overall health and may be associated with various metabolic issues, they do not directly cause hypoalbuminemia in a straightforward manner like starvation does. Obesity often entails increased protein stores, hypertension may not notably affect serum albumin levels, and hyperlipidemia primarily concerns lipid metabolism without a direct link to albumin production. Therefore, starvation stands out as a definitive cause of this condition.
