Diverticulitis occurs when small pouches in the colon, called diverticula, become inflamed or infected.Â
When untreated, diverticulitis can lead to abscesses, perforation or bleeding, especially in severe cases such as perforated diverticulitis. With early treatment, most people recover well and avoid long-term complications.
Symptoms often appear suddenly and range from mild discomfort to severe pain.
A proper diagnosis confirms whether symptoms are due to inflammation alone or complications such as abscess, obstruction or perforated diverticulitis. Because diverticulitis can mimic other abdominal conditions, accurate testing is essential before starting treatment. Early diagnosis helps prevent severe infection, bowel rupture and repeated flare-ups.
Diverticulitis varies widely in severity. The type diagnosed directly influences treatment decisions, recovery time and long-term risks. Some patients experience mild, self-limiting inflammation, while others develop serious, life-threatening complications.Â
Identifying the correct type early helps specialists determine whether home care, hospital treatment or surgery is required.
This is the most common form, where inflammation is limited to the diverticula without spread to nearby tissues. Symptoms typically include lower abdominal pain (often on the left side), fever, bloating, nausea and mild changes in bowel habits.Â
Most patients recover well with oral antibiotics, bowel rest, hydration and short-term dietary adjustments. Hospital admission is usually not required unless symptoms worsen or oral intake is poor.
This occurs when inflammation extends beyond the diverticula and leads to serious complications such as abscess formation, perforated diverticulitis, bowel obstruction or fistula formation between the bowel and nearby organs (such as the bladder or skin).Â
Patients often develop severe pain, high fever, persistent vomiting or signs of sepsis. Management usually requires hospitalisation, intravenous antibiotics, possible image-guided drainage, and, in some cases, emergency surgery. Delayed treatment increases the risk of life-threatening infection and long-term bowel damage.
This refers to repeated flare-ups over time, sometimes occurring multiple times within a year. Ongoing inflammation can lead to bowel wall scarring, narrowing (strictures), chronic pain and impaired bowel function.Â
Frequent recurrences may significantly affect quality of life and increase the risk of complications. Specialists may recommend regular monitoring, long-term dietary strategies or elective surgery in patients with repeated or severe episodes.

Without timely care, diverticulitis may lead to:
These steps reduce pressure on the colon and improve long-term outcomes.
Daily habits can help manage symptoms and prevent flare-ups.
Diverticulitis occurs when small pouches in the colon become inflamed or infected, leading to abdominal pain, fever and changes in bowel habits. While many cases are mild, some patients develop serious complications such as abscesses or perforation. Diverticulitis may present as uncomplicated, complicated or recurrent, depending on disease severity and frequency of flare-ups.Â
Uncomplicated cases involve localised inflammation and usually respond well to medical treatment. Complicated diverticulitis occurs when infection spreads beyond the colon and may require hospital care or surgery. Recurrent diverticulitis in Singapore can disrupt daily life and requires long-term prevention planning.
Management of diverticulitis begins with a consultation at a gastroenterology clinic or hospital emergency department for severe symptoms. A specialist assesses symptom severity and orders scans such as CT imaging to confirm the diagnosis and rule out complications. Once the type of diverticulitis is confirmed, treatment may include antibiotics, bowel rest and pain control, depending on severity.Â
Patients with complicated diverticulitis in Singapore may require hospitalisation, intravenous antibiotics or drainage procedures. After recovery, a colonoscopy is often advised to assess the colon and exclude underlying conditions such as cancer. Long-term care focuses on preventing recurrence through diet changes, hydration and regular monitoring.
You should seek medical attention if you develop persistent lower abdominal pain, fever, nausea or changes in bowel habits. These symptoms may indicate diverticulitis in Singapore and require prompt assessment to avoid complications. Seek urgent help if pain becomes severe, accompanied by vomiting or if you are unable to pass stool or gas.Â
Immediate medical care is also needed if there is rectal bleeding or signs of perforation, such as sudden worsening pain and abdominal rigidity. Delaying treatment increases the risk of abscess formation, bowel obstruction or perforated diverticulitis. Early diagnosis and structured treatment help reduce hospitalisation and protect long-term bowel health.
