Pain or cramping in the lower left abdomen
Fever or chills

Constipation or diarrhea
Bloating or excessive gas
Blood in the stool (in more severe cases)
How Dr. Scott Diagnoses This Condition?
Dr. Scott uses a step-by-step approach:
Medical History and Physical Exam
He reviews your symptom timeline-especially epigastric and lower-left abdominal pain-along with your bowel habits, dietary triggers, and any past episodes of diverticulitis.
Blood Tests
We check white blood cell count (WBC) and C-reactive protein (CRP) to detect infection or inflammation.
Imaging Studies
CT scan of the abdomen and pelvis to visualize inflamed or perforated diverticula and identify any abscesses.
Abdominal ultrasound as an alternative for patients who cannot undergo CT, to spot fluid collections or thickened colon walls.
Colonoscopy (After Acute Episode)
Once the inflammation subsides, a colonoscopy is performed to confirm the diagnosis, assess healing, and rule out other colonic diseases.

The most commonly used code is K57.32 for diverticulitis of the sigmoid colon without perforation. Dr. Scott's team will verify the exact code for your records.

Mild cases sometimes improve with rest, dietary adjustments, and antibiotics. Always consult Dr. Scott before self-managing to prevent complications.
What does stool look like with diverticulitis?
