15 Unexpected Twists Your Body Takes With Diuretics

8. Low Blood Pressure (Hypotension)

By reducing blood volume, diuretics can cause blood pressure to drop too low, leading to hypotension. Symptoms include dizziness, blurred vision, fainting, fatigue, and confusion—especially when standing up too quickly. This is known as orthostatic hypotension. Patients experiencing these symptoms should rise slowly from sitting or lying positions and discuss dosage adjustments with their doctor. In some cases, electrolyte rebalancing or switching to a different class of medication may be required to avoid further episodes.
