Thiazide diuretics and the risk of hip fracture.

Thiazide diuretics are one of the most commonly prescribed antihypertensive agents worldwide. Thiazides reduce urinary calcium excretion. Chronic ingestion of thiazides is associated with higher bone mineral density. It has been suggested that thiazides may prevent hip fracture. However, there are concerns that diuretics, by increasing the risk of fall in elderly, could potentially negate its beneficial effects on hip fracture.
