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

Thiazide diuretics are a class of medications commonly used to treat hypertension and edema. They primarily work by promoting the excretion of sodium and water through the kidneys. While thiazide diuretics can lead to various side effects, not all conditions associated with these medications are considered direct side effects.

Hyperglycemia may occur because thiazide diuretics can impair insulin release and increase insulin resistance, potentially leading to elevated blood glucose levels. Hypercalcemia is another potential side effect, as thiazides can increase calcium reabsorption in the renal tubules, causing elevated calcium levels. Pancreatitis, although not typical, could theoretically occur in some cases due to electrolyte imbalances or other factors, making it more of an uncommon adverse event linked to thiazide use.

Diarrhea, on the other hand, is not a common side effect of thiazide diuretics. These medications typically do not cause gastrointestinal disturbances like diarrhea; rather, they might lead to issues such as constipation due to altered fluid and electrolyte balance. Therefore, when assessing the side effects commonly attributable to thiazide diuretics, diarrhea stands out as not being associated with them, making it the correct choice for this question.
