Common Causes and Risk Factors

  • Smoking
  • Use of certain medications (NSAIDs, steroids)

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.

Treatment

Our Team offers a full range of care for diverticulitis.

1. Lifestyle and Diet Changes

  • Initial bowel rest followed by gradual reintroduction of low-residue foods
  • High-fiber diet recommendations: oatmeal, beans, vegetables
  • Adequate hydration to support bowel function
  • Avoidance of nuts, seeds, or other trigger foods if intolerance occurs
  • Gentle physical activity such as walking to stimulate gut motility

2. Medications

  • Targeted antibiotics to treat and resolve infection
  • Acetaminophen for pain control
  • Avoidance of NSAIDs (ibuprofen, naproxen) and high-dose steroids unless specifically directed

3. Minimally Invasive or Advanced Procedures

  • Image-guided drainage of any abscess using a small catheter
  • Laparoscopic resection of diseased colon segment when surgery is required

Frequently Asked Questions

Does diverticulitis go away?

Yes. Many people recover with rest, antibiotics, and diet modifications. Long-term fiber adjustments can help prevent future flare-ups.

How long does recovery take?

Most patients feel better within about a week. If surgery is required, full healing may take several additional weeks.

What is the ICD-10 code for diverticulitis?

The ICD-10 code for diverticulitis is K57.x, covering various types with or without complications.

What does poop look like with diverticulitis?

Stools may be loose or coated, contain mucus, and in severe inflammation there can be blood.

Which drugs should I avoid?

Avoid NSAIDs like ibuprofen or aspirin, and high-dose steroids unless directed by your doctor, as they can worsen colon irritation.

Can I stop this from happening again?

Yes. A high-fiber diet, adequate hydration, and regular exercise significantly lower the risk of another attack.
