Does Hydrochlorothiazide Cause Weight Loss?

Hydrochlorothiazide is a medication used to treat hypertension or high blood pressure. It is a diuretic drug that acts by inhibiting the kidneys' ability to retain water. This reduces the volume of the blood, decreasing blood return to the heart and thus cardiac output. It also can help the body get rid of excess water while still keeping calcium. So, does hydrochlorothiazide cause weight loss?

Losing water weight

Because the product is a diuretic, losing "water weight" is possible. The drug does not allow your body to retain water, so this fluid is passed out of the body through additional urination. The weight lost through this process is usually not a significant amount in most users, but it is noticeable. Rapid weight loss while taking hydrochlorothiazide is not common and is possibly a sign of a more serious medical condition. Consult a doctor as soon as possible if weight loss is significant.

Other side effects

All medicines may cause side effects, but many people have no, or minor, side effects when taking hydrochlorothiazide. Check with your doctor if any of these most common side effects persist or remain bothersome when using this drug: constipation, diarrhea, dizziness, light-headedness, loss of appetite, nausea or temporary blurred vision. This is not a complete list of side effects that may occur. If you have questions about specific side effects, it is smart to contact a medical professional.

As a safe, effective drug for treating hypertension, hydrochlorothiazide has few side effects. If you are suffering significant weight loss while taking the drug, seek medical help as soon as possible.
