What is a diverticulitis flare-up?

A diverticulitis flare is an episode in which a person experiences active symptoms of diverticulitis. Diverticulitis is a condition marked by inflammation or infection of pockets, medically called diverticula, that form in the digestive system. When symptoms of infection and inflammation are evident, a person is said to have a flare. There are many symptoms that can mark an outbreak of this condition. Among the most common, however, are those such as pain in the abdominal region, fever, difficulty urinating, upset stomach and changes in bowel habits; a person with this condition may also experience bleeding in the gastrointestinal tract.

One of the common signs of a diverticulitis flare-up is pain in the abdominal region. A person having a flare-up of symptoms may notice a sudden onset of pain in the lower left section of their abdomen. Along with this pain, you may experience tenderness when your abdomen is touched. The sudden onset of pain that accompanies a diverticulitis flare-up is very common, but some people have pain that starts gradually and increases in intensity over days.

An individual may also experience nausea and vomiting when having a diverticulitis flare-up. These symptoms may or may not occur along with constipation and diarrhea. It's important to note that a severe case of nausea and vomiting during a diverticulitis flare-up may be a sign of a complication of the condition. For example, symptoms of severe stomach upset can occur when an individual has an intestinal obstruction.

A fever can also develop during a diverticulitis flare-up. Usually, the high body temperatures present during a diverticulitis flare-up develop as a result of an infection in the pouches that have formed in the digestive tract. If the fever is high, this may be a sign of a serious infection that may require the patient to be hospitalized.

When a person has a flare-up of diverticulitis, they may also develop problems related to urination. For example, a person with this condition may have to urinate more often than usual during a flare of symptoms. Sometimes urination can even be accompanied by pain. However, it is worth noting that urinary symptoms do not develop in all patients with diverticulitis.

An outbreak of diverticulitis can also be accompanied by bleeding in the digestive tract. This can happen when a blood vessel bursts in one of the inflamed or infected bursae. In many cases, bleeding caused by a ruptured blood vessel goes away on its own. If not, doctors may perform a colonoscopy to find the source of the bleeding and stop it.
