Diverticulitis is an inflammatory condition involving diverticula, small sacs that form in the wall of the colon. This condition can occur in association with diverticulosis, a condition in which diverticula develop in the colon. While many individuals with diverticulosis experience no problems, diverticulitis can cause severe symptoms that require appropriate treatment. In this article, we will explore the symptoms, causes and treatment options for diverticulitis. Diverticulitis manifests itself with a range of symptoms, which can vary from mild to intense. Abdominal pain is one of the most common symptoms, usually located in the left side of the lower abdomen. This pain may be continuous or intermittent and may be accompanied by sensitivity to touch. Other symptoms include fever, nausea, vomiting, diarrhea or constipation, and changes in normal bowel rhythm. In some cases, rectal bleeding may also occur. The exact causes of diverticulitis are not yet fully understood, but it is believed to be related to several factors. The formation of diverticula in the colon is attributed to a combination of intestinal wall weakness and increased internal pressure. Risk factors include older age, a low-fiber diet, obesity and physical inactivity. In addition, genetic predisposition may increase the risk of developing diverticulitis. Treatment of diverticulitis depends on the intensity of symptoms and the presence of complications. In mild cases, it may be sufficient to follow a low-residue diet and take antibiotics to fight the infection. The low-residue diet involves eating easily digestible, low-fiber foods in order to reduce stress on the inflamed colon. Bed rest can help relieve pain and allow the colon to heal. In severe cases, hospitalization may be necessary. During hospitalization, patients may receive antibiotics through an IV and intravenous fluids. In some cases, percutaneous drainage may be necessary to remove pus accumulation in the presence of diverticular abscesses. If complications such as perforation or bowel obstruction occur, surgery may be required to remove the affected part of the colon.
