Diverticulitis, a condition arising from inflamed pouches in the intestine, can manifest in various noticeable changes in your bowel movements. These changes, ranging from consistency to color and odor, are crucial indicators that can prompt timely diagnosis and management. Diverticulitis itself stems from diverticulosis, where small pouches called diverticula form in the digestive tract, most commonly in the colon. When these pouches become inflamed or infected, diverticulitis develops.
Understanding what your poop looks like when you have diverticulitis is essential for early detection. This condition significantly impacts digestive health and is a common reason for outpatient visits. Recognizing the alterations in stool, alongside other symptoms, can empower you to seek medical attention promptly.

Symptoms of Diverticulitis and Stool Changes
While diverticulosis, the presence of diverticula without inflammation, often shows no symptoms, diverticulitis presents a range of symptoms, including noticeable changes in stool. These stool alterations are often a direct result of the inflammation and infection affecting the colon. Key symptoms of diverticulitis, beyond stool changes, include:
- Sudden and Severe Abdominal Pain: Typically located in the lower left abdomen, this pain can be persistent and intense.
- Fever and Chills: Indicating an infection, fever is a common sign of diverticulitis.
- Nausea and Vomiting: Digestive upset is a frequent symptom accompanying the inflammation.
- Changes in Bowel Habits: This includes both constipation and diarrhea, often alternating as the condition progresses.
The changes in stool associated with diverticulitis are diverse and reflect the various ways the inflammation impacts the digestive system. These changes can include:
- Diarrhea (Loose, Watery Stools): Inflammation can irritate the colon, leading to increased bowel motility and watery stools.
- Constipation (Hard, Pellet-like Stools): Conversely, inflammation and potential narrowing of the colon can also cause constipation, resulting in hard, difficult-to-pass stools.
- Pencil-Thin Stools: If diverticulitis causes a stricture, or narrowing of the intestine, the stool may become thin and ribbon-like, often referred to as “pencil stools.” This narrowing obstructs the normal passage of stool, altering its shape.
- Mucus in Stool: Inflammation and infection in the bowel can lead to increased mucus production. Seeing mucus coating the stool can be a sign of diverticulitis or other bowel issues.
- Bright Red or Maroon Stool (Rectal Bleeding): Bright red blood in the stool usually indicates bleeding in the lower colon or rectum, often due to diverticular bleeding. Maroon-colored stool can also indicate lower gastrointestinal bleeding.
- Black, Tarry Stool (Melena): Black, tarry stools, known as melena, suggest bleeding higher up in the digestive tract, such as the upper colon or small intestine. The blood becomes darkened as it travels through the digestive system. This type of stool change requires immediate medical attention.
- Foul-Smelling Stool: An unusually strong and unpleasant odor in stool can be due to infection within the diverticula or the presence of blood.
When to Seek Immediate Medical Attention for Diverticulitis Symptoms
Regardless of whether you have a prior diagnosis of diverticulitis, certain symptoms warrant immediate medical evaluation. These are warning signs that could indicate a severe complication or require urgent treatment:
- Rectal Bleeding or Blood in Stool: Any visible blood, especially bright red, maroon, or black tarry stools, is a serious symptom.
- High Fever: A fever above 100.4°F (38°C) can indicate a worsening infection.
- Persistent Nausea and Vomiting: Inability to keep food or fluids down can lead to dehydration and requires medical intervention.
- Severe or Worsening Abdominal Pain: Intense, sudden, or increasing pain, especially if localized to the lower left abdomen, is a hallmark of diverticulitis and potential complications.
Complications of Diverticulitis
While many cases of diverticulitis are manageable with medication and dietary changes, complications can arise in a significant percentage of individuals, ranging from 15% to 20%. Some of these complications can be severe and even life-threatening:
- Abscess: Infection can lead to the formation of a pus-filled pocket, or abscess, near the inflamed diverticula.
- Perforation: In severe cases, an inflamed diverticulum can rupture, leading to a hole in the colon wall and leakage of intestinal contents into the abdominal cavity. This is a surgical emergency.
- Peritonitis: If perforation occurs, it can cause peritonitis, an infection of the abdominal lining, which is a life-threatening condition.
- Fistula: An abnormal connection, or fistula, can form between the colon and other organs, such as the bladder, vagina, or skin.
- Stricture: As mentioned earlier, repeated inflammation can lead to scarring and narrowing of the colon, resulting in a stricture and potentially causing chronic bowel obstruction.
- Bleeding: Diverticular bleeding can occur when blood vessels near the diverticula become weakened and rupture.
Causes and Risk Factors for Diverticulitis
Diverticulitis typically begins with diverticulosis. The development of diverticula is strongly linked to:
- Low-Fiber Diet: A diet lacking in fiber contributes to constipation. Straining during bowel movements increases pressure in the colon, potentially leading to the formation of diverticula over time.
- Age: Diverticulosis is more common in adults over the age of 40, and the risk of diverticulitis increases with age.
Other factors can increase the risk of developing diverticulosis and subsequently diverticulitis:
- Genetics: A family history of diverticular disease may increase your susceptibility.
- High Red Meat Consumption: Diets high in red meat have been associated with an increased risk.
- Obesity: Excess weight, particularly abdominal obesity, is a risk factor.
- Smoking: Tobacco use increases the risk of diverticulitis and its complications.
- Excessive Alcohol Consumption: Heavy alcohol intake is linked to an elevated risk.
- Lack of Exercise: Physical inactivity can contribute to constipation and increase the risk.
- Certain Medications: Regular use of NSAIDs (nonsteroidal anti-inflammatory drugs) like aspirin and ibuprofen can increase the risk of diverticulitis and bleeding.
How Diverticulosis Progresses to Diverticulitis
The inflammation in diverticulitis is often triggered by:
- Trapped Stool: Hardened stool can become lodged in the diverticula, irritating the pouch walls and leading to inflammation.
- Bacterial Overgrowth: Trapped stool can also foster bacterial growth within the pouches, resulting in infection.
- Weakened Diverticula Walls: Over time, the walls of the diverticula can thin and become more susceptible to inflammation and rupture.
Diagnosis of Diverticulitis
Diagnosing diverticulitis involves a comprehensive evaluation:
- Medical History and Physical Exam: Your doctor will inquire about your symptoms, medical history, diet, and family history. A physical exam will include abdominal palpation to check for tenderness and listening to bowel sounds.
- Imaging Tests:
- CT Scan: A CT scan of the abdomen and pelvis is the most common and effective imaging technique for diagnosing diverticulitis. It can visualize the inflamed diverticula and any complications like abscesses or perforations.
- Colonoscopy or Sigmoidoscopy: While not typically used during an acute diverticulitis flare-up due to the risk of perforation, these procedures may be performed after the inflammation subsides to rule out other conditions, such as colon cancer.
- Blood Tests: Blood tests can help assess for signs of infection, such as elevated white blood cell count.
Treatment for Diverticulitis
Treatment strategies for diverticulitis depend on the severity of the condition:
- Antibiotics: Antibiotics are the cornerstone of treatment for most cases of diverticulitis, targeting the bacterial infection. They can be administered orally or intravenously, depending on the severity.
- Dietary Modifications:
- Clear Liquid Diet: Initially, a clear liquid diet is often recommended to rest the bowel and reduce inflammation.
- Low-Fiber Diet: Following the clear liquid diet, a low-fiber diet is typically advised to minimize bowel movements and allow the colon to heal.
- High-Fiber Diet: Once the acute inflammation resolves, a gradual transition to a high-fiber diet is crucial for long-term management. Fiber helps promote regular bowel movements and prevent constipation, reducing the risk of future diverticulitis flares.
- Pain Management: Pain relievers may be prescribed to manage abdominal pain.
- Surgery: Surgery is reserved for severe cases with complications like perforation, abscess, fistula, or recurrent diverticulitis that doesn’t respond to conservative treatment. Surgical options may include bowel resection to remove the affected segment of the colon.
Summary: Recognizing Stool Changes in Diverticulitis
Diverticulitis can significantly impact bowel movements, leading to changes in stool consistency, color, and odor. Recognizing what poop looks like with diverticulitis – including diarrhea, constipation, pencil stools, mucus, and bloody or tarry stools – is vital for early detection and seeking prompt medical care. Understanding these stool changes, along with other symptoms like abdominal pain and fever, empowers individuals to take proactive steps towards diagnosis and effective management of diverticulitis, ultimately promoting better digestive health.
