While UC patients are often considered "cured" by creating a pouch, there are still many complications that can arise. While it is a significant improvement compared to living with UC or other related diseases, patients living with a pouch may still face daily pains and discomforts as their body compensates for the loss of such an important organ. Many patients experience the inability to sleep through the night, a drastically changed diet, severe and frequent gas pain, nutrient deficiencies, and the inability to digest certain foods. In some cases where the pouch was formed to manage colitis, inflammation can return to the pouch in a similar way to the original inflammation in the colon. This is known as pouchitis.
