Eating, Diet, & Nutrition

Can my eating, diet, and nutrition help prevent bladder infections?

Experts don’t think eating, diet, and nutrition play a role in preventing or treating bladder infections. Although some research shows that cranberry juice, extract, or pills may help prevent these infections, not enough evidence shows this. Research shows that cranberry products are not effective in treating a bladder infection if you already have one.2

Can drinking liquid help prevent or relieve bladder infections?

Yes. Drink six to eight, 8-ounce glasses of liquid a day. Talk with a health care professional if you can’t drink this amount due to other health problems, such as urinary incontinence, urinary frequency, or kidney failure. The amount of liquid you need to drink depends on the weather and your activity level. If you live, work, or exercise in hot weather, you may need more liquid to replace the fluid you lose through sweat.
