Which one of these is a common symptom of hyperthyroidism?

• A. Frequent bowel movements
• B. Chronic fatigue
• C. Hypotension
• D. Loss of appetite

Answer: (A)

Frequent bowel movements are a common symptom of hyperthyroidism due to the increased metabolic rate associated with the condition. Hyperthyroidism leads to an overproduction of thyroid hormones, which can speed up the body's metabolism, affecting various bodily functions, including digestion. This acceleration can cause a person to experience more frequent bowel movements, resulting in changes to their normal bathroom habits.

In contrast, chronic fatigue is generally associated with hypothyroidism, where the body's metabolism slows down, leading to a lack of energy. Hypotension, or low blood pressure, is not characteristic of hyperthyroidism; instead, individuals often experience increased heart rate and may have elevated blood pressure. Loss of appetite might occur due to anxiety or other psychological factors linked to hyperthyroidism, but it is not a predominant symptom of the condition, which often leads to increased appetite owing to heightened metabolic activity.
