Several conditions can mimic the symptoms of diverticulitis, leading to potential misdiagnosis. These include appendicitis, Crohn’s disease, irritable bowel syndrome (IBS), peptic ulcer disease, a small bowel obstruction, gastroenteritis, urinary tract infections (UTI), and ovarian cysts or pelvic inflammatory disease (PID).
- Irritable bowel syndrome (IBS): IBS shares some similar symptoms with diverticulitis, such as abdominal pain, bloating, and changes in bowel movements. Proper evaluation is necessary to differentiate between the two conditions.
- Inflammatory bowel diseases (IBD): Conditions like Crohn’s disease or ulcerative colitis can present symptoms similar to diverticulitis, including abdominal pain, diarrhea, and rectal bleeding. Medical examinations, imaging studies, and laboratory tests are crucial for an accurate diagnosis.
- Gastroenteritis: Also known as the stomach flu, gastroenteritis can cause abdominal pain, diarrhea, nausea, and vomiting. Differentiating between gastroenteritis and diverticulitis may require a thorough medical evaluation.
- Urinary tract infection (UTI): In some cases, a UTI can cause lower abdominal pain that may be mistaken for diverticulitis. An assessment by a healthcare professional can help identify the underlying cause.
- Ovarian cysts or pelvic inflammatory disease (PID): Women may experience lower abdominal pain due to conditions such as ovarian cysts or PID, which can be mistaken for diverticulitis. Appropriate evaluation, including imaging and gynecological examination, is essential for accurate diagnosis.
- Appendicitis: Appendicitis is a condition in which the appendix, a small, finger-shaped pouch that projects from the colon, becomes inflamed or infected. Appendicitis can cause similar symptoms to diverticulitis, such as pain in the lower right abdomen, fever, nausea, and vomiting. However, appendicitis is usually more sudden in onset and more severe than diverticulitis.
- Crohn’s disease: Crohn’s disease is a chronic inflammatory bowel disease that can affect any part of the digestive tract, from the mouth to the anus. Crohn’s disease can cause symptoms similar to diverticulitis, such as abdominal pain, fever, diarrhea, and weight loss. However, Crohn’s disease is usually more severe than diverticulitis and can cause other symptoms, such as mouth sores, joint pain, and skin problems.
- Peptic ulcer disease: Peptic ulcer disease is a condition in which the lining of the stomach or small intestine becomes damaged, forming an ulcer. Peptic ulcer disease can cause symptoms similar to diverticulitis, such as abdominal pain, indigestion, and heartburn. However, peptic ulcer disease is usually not as severe as diverticulitis and does not cause fever or other systemic symptoms.
- Small bowel obstruction: A small bowel obstruction is a blockage in the small intestine. A small bowel obstruction can cause symptoms similar to diverticulitis, such as abdominal pain, nausea, vomiting, and constipation. However, a small bowel obstruction is usually more sudden in onset and more severe than diverticulitis.
Get A Proper Diagnosis
If you have any of the symptoms of diverticulitis, it is important to see a doctor to get a diagnosis. Your doctor will likely ask you about your symptoms and medical history. They may also perform a physical exam and order tests, such as a blood test, urinalysis, and imaging tests, such as a CT scan.
