Can Spironolactone Cause Weight Gain? Let’s Clear It Up
Spironolactone is widely prescribed for hormonal acne, PCOS symptoms, and even hair loss—but many women pause before starting it, wondering: Can spironolactone cause weight gain?
At Oana Health, we believe in empowering women with facts—not fear. Let’s break down what spironolactone really does in your body, and whether it’s likely to affect your weight.
What Is Spironolactone and How Does It Work?
Spironolactone is a potassium-sparing diuretic—meaning it helps your body get rid of excess sodium and water, without losing potassium. But in women’s health, it’s most often used off-label to block androgens (male hormones like testosterone) that can contribute to:
- Hormonal acne
- Unwanted facial hair
- Scalp hair thinning
- PCOS-related symptoms
By blocking androgen receptors, spironolactone reduces oil production and helps balance hormone-driven skin and hair issues.
