I have ibs-c and increased rectal pressure what can i do to lower the rectal pressure and maybe help the constipation?

Take care.: You will relieve the pressure when you start having regular bowel movements. The most important thing to do is to watch your lifestyle. Eat healthy whole high fiber foods. Drink a lot of water to stay hydrated. Get good bacteria into your system by eating fermented foods or by taking a good quality probiotic. You can also take vitamin C and magnesium citrate to help alleviate the constipation.
