Which of the following is NOT a common side effect of diuretics?

Diuretics are well-known for their ability to promote the excretion of water and electrolytes through urination, which can lead to several common side effects. Dehydration, electrolyte imbalance, and hypotension are all frequently observed when patients are on diuretics due to the increased fluid and electrolyte loss.

Dehydration occurs because diuretics increase urine production, which can result in a reduction of total body fluids if fluid intake does not compensate adequately. Electrolyte imbalances, particularly low levels of potassium (hypokalemia), sodium, and magnesium, are common as diuretics can wash out these essential electrolytes. Hypotension can also be a side effect as the loss of fluid volume can decrease blood pressure.

In contrast, increased appetite is not associated with diuretics. In fact, many patients may experience a decrease in appetite, especially if they suffer from the potential side effects of discomfort or nausea due to changes in electrolyte levels or dehydration. Therefore, the option that states increased appetite is not a common side effect of diuretics, making it the correct answer.
