Diverticulosis / Diverticular disease
One of the first things you will notice when this begins to affect you is a change from the usual toilet habit. It becomes irregular and you can have difficulty passing out the stools. You will have a bloated feeling until you are successful in the toilet. Another very common symptom is a pain in your lower abdomen which starts and stops many times. This is usually on the lower left-hand side.
This is already inflammation. So the condition has similar symptoms but much worse. The pain will be more severe and continuous. You will also experience a high fever. You will feel tired, weak, and nauseous (very sick with vomiting). Diarrhea and frequent going to the toilet can happen.
Diverticulitis is a very serious stage of diverticular disease. It has symptoms similar to that of diverticulosis but with the added complications of inflammation.
