If left untreated, diverticulitis may lead to a collection of pus (called an abscess) outside the colon wall or a generalized infection in the lining of the abdominal cavity, a condition referred to as peritonitis.
In about 95 out of 100 people, uncomplicated diverticulitis goes away on its own within a week. In about 5 out of 100 people, the symptoms stay and treatment is needed.
Intestinal inflammation from diverticulitis can lead to the development of fistulas that connect the large intestine with other organs. Fistulas usually form when an inflamed diverticulum in the large intestine is touching another organ (such as the bladder).
If you don't treat it, diverticulitis can lead to serious complications that require surgery: Abscesses, collections of pus from the infection, may form around the infected diverticula. If these go through the intestinal wall, you could get peritonitis. This infection can be fatal.
In rare cases, an infected diverticulum (pouch in your colon) can split, spreading the infection into the lining of your abdomen (perforation). An infection of the lining of the abdomen is known as peritonitis. Peritonitis can be life-threatening, and requires immediate treatment with antibiotics.
A cohort study including 445,456 Danish adults found that patients with diverticular disease had a 120% higher risk of colon cancer compared to those without diverticulitis after an 18-year follow-up period [2]. This positive association was also revealed in several other observational studies [3,4,5].
Living a Long Life With Diverticulitis. For most people, diverticulitis won't affect their life span. Many people don't even know they have diverticular disease. Only a small percentage will have symptoms, and an even smaller number will have complications.
People with diverticulosis often have no symptoms, but they may have bloating and cramping in the lower part of the belly. Rarely, they may notice blood in their stool or on toilet paper. Symptoms of diverticulitis are more severe and often start suddenly, but they may become worse over a few days.
Complications. About 25% of people with acute diverticulitis develop complications, which may include: An abscess, which occurs when pus collects in the pouch. A blockage in your bowel caused by scarring.
Diverticulosis: You can have it for years and never know — if you take care of yourself. About one or two percent of patients under 30 experience diverticulosis while people age 60 and older have some degree of the condition.
You can have diverticulosis and not have any pain or symptoms. But symptoms may include mild cramps, swelling or bloating, and constipation. These symptoms can also be caused by irritable bowel syndrome, stomach ulcers, or other health problems.
People with diverticulosis might not experience symptoms or complications that require treatment. Patients can learn they have the condition when they get a colonoscopy, X-ray, or CT scan for an unrelated gastrointestinal issue.
Actually, no specific foods are known to trigger diverticulitis attacks. And no special diet has been proved to prevent attacks. In the past, people with small pouches (diverticula) in the lining of the colon were told to avoid nuts, seeds and popcorn.
Mild cases of diverticulitis are usually treated with antibiotics and a low-fiber diet, or treatment may start with a period of rest where you eat nothing by mouth, then start with clear liquids and then move to a low-fiber diet until your condition improves. More-severe cases typically require hospitalization.
In more severe diverticulitis, when a perforation or an abscess is suspected, you may experience significant abdominal pain, an inability to tolerate food, constipation, or fever and chills. In this situation, NYU Langone doctors may recommend hospitalization for treatment and monitoring.
A low-fiber diet leads to constipation, which increases pressure within the digestive tract with straining during bowel movements. The combination of pressure and straining over many years likely leads to diverticulosis.
When stress is added to the overall picture, the problem of diverticulitis becomes an issue. This is due to the body impulses that will immediately address stressful situations by shifting the oxygen and blood from the digestive tract to the brain and muscles.
Contact a GP as soon as possible if you have symptoms of diverticular disease or diverticulitis. If you've already been diagnosed with diverticular disease, you usually do not need to contact a GP – the symptoms can be treated at home. But if you have any bleeding or severe pain, seek immediate medical advice.
If you have diverticulitis, you may need to go into hospital if: your symptoms are really bad. your symptoms don't get better after two days of treating them at home. you have a weak immune system.
Many people know someone who had an operation for diverticulitis and ended up having a colostomy. In most cases of surgery for diverticulitis, a colostomy is not required. However, sometimes this is not the case.
