What condition can lead to hypocalcemia due to low intake?

Hypocalcemia refers to a lower-than-normal level of calcium in the blood, which can result from various factors, including dietary intake. Alcoholism is a condition associated with malnutrition and lower dietary intake of essential nutrients, including calcium. Chronic alcohol consumption can lead to dietary deficiencies, as alcohol can suppress appetite and result in poor nutritional choices. Additionally, alcohol can impair the absorption of calcium from the gastrointestinal tract and affect vitamin D metabolism, which is crucial for calcium regulation.

In contrast, hypertension, heart failure, and obesity do not typically lead directly to hypocalcemia due to low intake. These conditions may have other associations and implications for calcium levels but are not primarily linked to dietary deficiencies of calcium. Therefore, alcoholism is the most relevant condition in this context for inducing hypocalcemia through inadequate intake.
