The primary risk factor for diverticulitis is increasing age, with most cases occurring in individuals over 50. Other factors that increase your risk include specific lifestyle choices, genetic predisposition, and certain medications.
While no specific foods are proven to trigger diverticulitis attacks, a diet rich in high-fiber foods can help maintain digestive health and reduce the risk of complications. High-fiber foods soften waste, decreasing pressure in the digestive tract. Examples include: Fruits.
The most important risk factor is age. After the age of 40 they become more common. With increasing age about 2 out of 3 people will develop diverticula during their lifetime. More people are being diagnosed, especially people under 45 years of age.
Other symptoms of diverticulitis can include: a high temperature (fever) of 38C (100.4F) or above. a general feeling of being tired and unwell. feeling sick (nausea) or being sick (vomiting)
What is diverticular bleeding? Diverticular bleeding occurs when pouches ( diverticula ) that have developed in the wall of the large intestine (colon) bleed. If you have these pouches, you have a condition called diverticulosis . Diverticular bleeding causes a large amount of blood to appear in your stool.
Diverticulitis perforation is a medical emergency with symptoms like sudden, severe abdominal pain (often lower left), high fever, chills, rapid heart rate, nausea, vomiting, and a rigid, tender abdomen, as bowel contents leak into the abdominal cavity (peritonitis). It requires immediate medical attention, with signs of worsening infection like difficulty breathing or confusion signaling sepsis.
The worst things for diverticulitis during a flare-up are high-fiber foods, red/processed meats, sugar, fat, alcohol, and NSAIDs like ibuprofen, as they can worsen inflammation and symptoms; instead, focus on a temporary low-fiber diet (liquids/soft foods) and gradually reintroduce fiber after healing to prevent future attacks, consulting your doctor for personalized advice.
Other signs and symptoms of diverticulitis may include:
When diverticulitis leads to sepsis, look out for these specific symptoms:
The duration of a diverticulitis flare-up can vary. A mild flare-up can last from a few days to a week, while more severe cases may take longer to subside. The duration can also depend on your overall health, any underlying conditions and timing of treatment.
Men are more likely to have bleeding from diverticular disease. Other risk factors for diverticular disease include use of NSAIDS, aspirin, steroids, opioids, smoking and sedentary lifestyle. Family history and genetics is also an important risk factor for development of diverticulitis.
Symptoms of a bowel perforation include:
Laboratory Tests: Blood tests may be ordered to help assess inflammation, infection, and other markers of diverticulitis. Common blood tests used in the diagnosis of diverticulitis include: Complete blood count (CBC): Elevated white blood cell count (leukocytosis) may indicate an inflammatory response or infection.
Causes of diverticular disease and diverticulitis
It's unclear why some people develop diverticula, or go on to get diverticular disease or diverticulitis. But increasing age and having a diet that's low in fibre are the main risk factors.
Stage I: Diverticulitis with phlegmon or localized pericolic or mesenteric abscess. This means there are inflammatory masses or abscesses in the fat surrounding the colon or the folds of the small intestine. Stage II: Diverticulitis with walled-off pelvic, intra-abdominal, or retroperitoneal abscess.
Treatment may consist of measures including: Taking painkillers to reduce discomfort. These may be over-the-counter pain medicines such as paracetamol or stronger medicines that require a prescription. Taking Buscopan may help with cramping abdominal pain.
Diverticulitis comes from infection and inflammation within small pouches (diverticula) that form in the colon wall, often due to high pressure from straining to pass hard, low-fiber stools, trapping bacteria and food, leading to blockage and infection. Risk factors include a low-fiber diet, constipation, obesity, lack of exercise, smoking, red meat, and age, though doctors don't know the exact cause.
Common alternative conditions that can clinically mimic diverticulitis include small bowel obstruction, primary epiploic appendagitis, acute cholecystitis, appendicitis, ileitis, ovarian cystic disease, and ureteral stone disease.
Diverticulitis perforation is a medical emergency with symptoms like sudden, severe abdominal pain (often lower left), high fever, chills, rapid heart rate, nausea, vomiting, and a rigid, tender abdomen, as bowel contents leak into the abdominal cavity (peritonitis). It requires immediate medical attention, with signs of worsening infection like difficulty breathing or confusion signaling sepsis.
Diverticulitis is diagnosed primarily with a CT scan (often with contrast), the most precise tool to see inflammation and complications, along with a doctor's review of your medical history, physical exam (checking for tenderness), and blood tests for infection. Other tests, like colonoscopy (to rule out cancer), ultrasound, or X-rays, might also be used to confirm the diagnosis and check for other issues.
Complications of diverticular disease
Perforation – a weakened pocket of bowel wall may rupture. The contents of the bowel can then seep into the abdominal cavity. Symptoms include pain, high fever and chills. A perforated bowel is a medical emergency.
However, you should seek immediate medical attention if your symptoms are not going away or you are feeling worse, such as having increasing pain, fever, bloody stools, or abdominal bloating with vomiting. Treatment depends on whether you have uncomplicated or complicated diverticulitis.
You should seek emergency medical attention for diverticulitis if you experience one or more of the following: Blood in stool. Excessive vomiting or severe nausea. Fever over 100.4 F.
Alternative medicine. A few small clinical trials found evidence that probiotic supplements to increase good bacteria in the colon may reduce risk of new episodes of diverticulitis.
