ProLon appears to affect each person a bit differently. Most people will not experience any significant or lasting changes in their bowel habits during or after ProLon. Indeed, no big changes in bowel habits were observed during clinical trials. However, any substantial change in eating habits or diet can result in changes in frequency, consistency and/or timing of bowel movements, so some variation is to be expected. If you’re concerned about changes in your bowel habits during ProLon, please discuss it with your healthcare provider.
