What are common signs and symptoms of hyperthyroidism?

1. Fatigue, weight gain, and depression

2. Tachycardia, weight loss, and hyperactive reflexes

3. Slow heart rate, cold intolerance, and heavy menstrual periods

4. Constipation, dry skin, and hair loss

The correct answer is: Tachycardia, weight loss, and hyperactive reflexes

The signs and symptoms associated with hyperthyroidism often stem from an overproduction of thyroid hormones, which can lead to an increased metabolic rate. Common manifestations include tachycardia, which is an elevated heart rate that can lead to palpitations and a feeling of racing heart. Weight loss is another frequent symptom, as the body's metabolism is accelerated, causing it to burn calories more quickly than usual. Hyperactive reflexes are also indicative of this condition, as the nervous system is often excitable due to the excess thyroid hormones, resulting in increased responsiveness to stimuli. The other choices provided include symptoms that are more characteristic of hypothyroidism or are not directly linked to an overactive thyroid. Therefore, the options that describe fatigue, weight gain, and depression are more aligned with hypothyroidism, while the presence of slow heart rate, cold intolerance, and heavy menstrual periods also indicate thyroid hormone deficiency rather than excess. Lastly, symptoms such as constipation, dry skin, and hair loss further suggest a lower level of thyroid hormone activity, which does not align with hyperthyroidism.
