Which condition is often associated with weight loss and increased appetite?

1. Addison's disease

2. Hyperthyroidism

3. Cushing's syndrome

4. Hypothyroidism

The correct answer is: Hyperthyroidism

Hyperthyroidism is characterized by an overactive thyroid gland, which produces excessive amounts of thyroid hormones. These hormones significantly influence metabolism, increasing the body's metabolic rate. As a result, individuals with hyperthyroidism often experience significant weight loss despite having an increased appetite. This paradox occurs because the body burns energy at a much faster rate due to the elevated hormone levels, leading to weight loss even when caloric intake is higher. In contrast, conditions like Addison's disease, Cushing's syndrome, and hypothyroidism generally lead to weight gain or difficulty maintaining a healthy weight due to their effects on metabolism and hormonal balance. Addison's disease can cause weight loss, but it is more commonly associated with decreased appetite and fatigue. Cushing's syndrome is often linked to increased weight gain, particularly around the abdomen and face. Hypothyroidism, on the other hand, typically results in weight gain due to a slowed metabolism. These distinctions highlight why hyperthyroidism is the condition that aligns with the symptoms of weight loss and increased appetite.
