How Dr. Nghia Nguyen Diagnoses Diverticulitis?
Dr. Nguyen uses a step-by-step approach:
Medical History and Physical Exam
He reviews your symptoms—changes in bowel habits, episodes of lower-left abdominal pain, fever—and discusses diet, activity level, and risk factors. He then performs a focused abdominal exam to check for tenderness, guarding, or masses.
Laboratory Tests
He orders blood work to look for elevated white blood cells and C-reactive protein, markers of inflammation. Occasionally, stool studies are done to rule out infectious causes.
Imaging Studies
CT Scan of the Abdomen - The gold standard to identify inflamed or perforated diverticula, abscesses, or fistulas.
Abdominal Ultrasound - A radiation-free option to detect abscesses or fluid collections, especially useful in patients who can't have a CT scan.
Colonoscopy (After Acute Episode)
Once the inflammation resolves, he may recommend a colonoscopy to evaluate the entire colon, confirm diverticular disease, and exclude malignancy or other conditions.
