In adults, what are common symptoms of hyperthyroidism?

1. Weight gain and lethargy

2. Anxiety, weight loss, and tremors

3. Cold intolerance and constipation

4. Dry skin and depression

The correct answer is: Anxiety, weight loss, and tremors

In adults, hyperthyroidism is characterized by an overproduction of thyroid hormones, which can lead to a variety of symptoms linked to an increased metabolism. The correct symptoms include anxiety, weight loss, and tremors. Anxiety arises from the heightened metabolic state associated with hyperthyroidism, which can cause increased nervousness and agitation in patients. Weight loss occurs because the excess thyroid hormones accelerate the metabolic rate, leading to an increase in energy consumption despite the individual’s appetite potentially remaining unchanged or even increased. Tremors, or fine shaking, are often observed due to increased sympathetic nervous system activity, further contributing to the overall restlessness and hyperactivity commonly seen in these patients. Other options describe symptoms associated with conditions that are the opposite of hyperthyroidism. For example, weight gain and lethargy are typically linked to hypothyroidism, where reduced thyroid hormone levels slow metabolism. Cold intolerance and constipation, along with dry skin and depression, are also indicative of hypothyroidism, highlighting the decrease in metabolic processes and energy levels. Understanding these differences is crucial for recognizing and diagnosing hyperthyroid conditions effectively.
