What is a common symptom of hypocalcemia?

• A. Muscle cramps
• B. Fatigue
• C. Weight gain
• D. Excessive thirst

Answer: (A)

Muscle cramps are a common symptom of hypocalcemia, which is a condition characterized by low levels of calcium in the blood. Calcium plays a crucial role in muscle contraction and nerve function. When calcium levels drop, nerve excitability increases, leading to muscle spasms and cramps. This heightened excitability is associated with neuromuscular irritability, which explains why muscle cramps are frequently reported in individuals with hypocalcemia.

In contrast, fatigue can result from various conditions and is not specific to low calcium levels. Weight gain typically relates to other metabolic or hormonal issues and is not directly connected to hypocalcemia. Excessive thirst, or polydipsia, can indicate an array of issues, such as diabetes or dehydration, but is not a primary symptom of low calcium levels.
