Symptoms of Diverticulitis That Should Not Be Ignored
Some symptoms of diverticulitis may suggest more significant inflammation or a complication and should be assessed promptly by a healthcare professional. The following table lists symptoms of diverticulitis that should not be ignored:
| Symptom | What It May Indicate |
| Persistent or worsening abdominal pain | Ongoing inflammation of a diverticulum |
| Severe abdominal tenderness | Significant inflammation in the colon. |
| High fever or chills | Infection or a strong inflammatory response. |
| Repeated vomiting | Significant gastrointestinal irritation or obstruction |
| Blood in the stool or rectal bleeding | Bleeding from the digestive tract. |
| Increasing abdominal swelling or bloating | Reduced bowel movement or intestinal inflammation. |
| Inability to pass stools or gas with increasing pain | Possible blockage of the bowel |
| Persistent symptoms despite initial improvement | Ongoing or recurrent inflammation |
Why Do Diverticulitis Symptoms Occur?
Diverticulitis symptoms develop when one or more small pouches, known as diverticula, in the wall of the colon become inflamed. In some cases, infection may also be present. The body's immune response to inflammation can increase blood flow and cause swelling around the affected area, leading to abdominal pain and tenderness.
The exact symptoms depend on the extent and location of inflammation. The sigmoid colon, which is the lower part of the large intestine, is a common location of diverticula in many people. As a result, pain is usually felt in the lower-left abdomen. However, pain may occur elsewhere depending on the location of the affected diverticulum.
It is also important to distinguish diverticulitis from diverticulosis. Diverticulosis means diverticula are present but are not inflamed. Hence, many people with diverticulosis have no symptoms. On the other hand, diverticulitis refers to the inflammation of one or more diverticula and is more likely to cause acute abdominal pain and other symptoms.
Symptoms of Diverticulitis That Require Immediate Medical Attention
Get urgent medical help if you experience the following symptoms:
-
Severe or rapidly worsening abdominal pain
-
A rigid, very swollen or extremely tender abdomen
-
High fever accompanied by worsening abdominal symptoms
-
Persistent vomiting or inability to keep fluids down
-
Inability to pass stools or gas, especially with abdominal swelling and pain
-
Heavy or persistent rectal bleeding
-
Fainting, severe weakness or signs of circulatory problems
-
Confusion or a significant deterioration in overall condition
-
Difficulty breathing or a rapid worsening of general health
These symptoms may indicate a serious complication or another acute abdominal condition. Prompt assessment is particularly important when severe pain occurs with fever, vomiting or marked changes in bowel function.
Symptoms of Diverticulitis Based on Type
Symptoms of uncomplicated and complicated diverticulitis can overlap. A healthcare professional may need imaging and other investigations to determine whether complications are present. Check out the symptoms of different types of diverticulitis:
| Type | Symptoms |
| Uncomplicated acute diverticulitis | Localised abdominal pain, abdominal tenderness, fever, nausea, constipation or diarrhoea |
| Complicated diverticulitis | Severe or persistent abdominal pain, high fever, worsening tenderness, vomiting, abdominal swelling or symptoms related to an abscess, perforation, fistula or obstruction. |
| Recurrent diverticulitis | Repeated episodes of abdominal pain and tenderness, sometimes accompanied by fever and changes in bowel habits. |
| Chronic symptomatic diverticular disease without acute diverticulitis | Recurrent lower abdominal pain, bloating, constipation or diarrhoea without the typical acute inflammatory picture. |
Symptoms of Diverticulitis-Specific Conditions
The following conditions are complications of diverticular disease and may require urgent medical assessment. The presence of rectal bleeding should also be evaluated because it can have several possible causes. Common symptoms of various diverticulitis-specific conditions are:
| Condition or Presentation | Common Symptoms |
| Diverticular abscess | Persistent abdominal pain, fever, tenderness and symptoms that may not improve as expected. |
| Perforated diverticulitis | Severe abdominal pain, marked tenderness, fever and possible signs of widespread abdominal inflammation. |
| Diverticular fistula | Symptoms vary according to the organs involved and may include recurrent urinary or bowel-related problems. |
| Diverticular bowel obstruction | Abdominal swelling, cramping, vomiting and difficulty passing stools or gas. |
| Diverticular bleeding | Passage of bright red or maroon blood from the rectum, often without abdominal pain. |
Can You Have Diverticulitis Without Symptoms?
Acute diverticulitis usually causes noticeable symptoms, particularly abdominal pain and tenderness. However, some people may have relatively mild symptoms, and the severity of symptoms does not always reflect the extent of inflammation.
It is also possible to have diverticulosis without symptoms. Many people have diverticula in the colon without knowing they are present, and these may be discovered incidentally during investigations for another reason.
Some people may also experience chronic abdominal symptoms such as bloating, constipation, diarrhoea or cramping without having an acute episode of diverticulitis. These symptoms can overlap with conditions such as irritable bowel syndrome (IBS), so they should not be used alone to diagnose diverticulitis.
When Can Diverticulitis Symptoms Become Life-Threatening?
Most cases do not lead to life-threatening complications, but severe or complicated diverticulitis can require urgent medical care. Some of these life-threatening symptoms include:
| Symptoms | What can happen |
| Perforation | A hole may develop in the colon, allowing bowel contents to leak into the abdominal cavity and potentially causing serious infection. |
| Peritonitis | Infection or inflammation of the lining of the abdominal cavity can occur following a perforation and requires urgent treatment. |
| Abscess | A collection of pus can develop near the inflamed diverticulum and may cause persistent pain, fever and worsening illness. |
| Bowel obstruction | Severe inflammation or scarring can interfere with the movement of bowel contents, causing pain, swelling, vomiting and inability to pass stools or gas. |
| Heavy gastrointestinal bleeding | Significant rectal bleeding can result in substantial blood loss and requires urgent medical assessment. |
| Severe infection | Infection associated with complicated diverticulitis can spread and lead to a serious systemic response. |
How are Diverticulitis Symptoms Diagnosed?
Diagnosis of diverticulitis is based on the person's symptoms, physical examination and appropriate investigations. The following table lists the tests used to diagnose diverticulitis:
| Diagnostic Test or Assessment | Purpose |
| Medical history and physical examination | Assesses the pattern and location of pain, bowel symptoms, fever and abdominal tenderness. |
| Blood tests | May help identify inflammation, infection or other abnormalities. |
| CT scan of the abdomen and pelvis | Can help confirm acute diverticulitis and identify complications such as abscess or perforation. |
| Stool tests | May be considered when diarrhoea or another gastrointestinal infection needs to be investigated. |
| Urine tests | May help assess urinary causes of abdominal symptoms or identify other conditions that can mimic diverticulitis. |
| Colonoscopy | May be recommended at an appropriate time in selected patients to investigate other bowel conditions; it is generally not used during an acute attack unless specifically indicated. |
| Other imaging tests | Ultrasound or other imaging may be used in selected situations depending on clinical circumstances and local practice. |
