Acidic and Alkaline Foods for a Balanced Interstitial Cystitis Diet

Page content

There has always been a very direct link between IC (also known as Interstitial Cystitis) and diet.

Interstitial Cystitis is a hardening of the bladder and the eroding of the bladder lining wall.

What you eat has a direct result on how bad you’ll feel and how long your flares (or increased symptomatic days) will be. There are some foods that are more acidic than others, these should be decreased in the diet, while some foods are more alkaline and can decrease the acid in your urine. Knowing what foods are what will help you have more good days and less flare days.

Some patients will want to buy pH strips and test their urine to see how acidic it is. Others can just try to drink enough water to keep their urine as close to clear as it can be, this will cut down on the uric acid concentration in your output. Either method will be fine, doing BOTH will help you out more than you’ll realize.
