Dr. Rishi Chadha, MD is a board‑certified gastroenterologist who specializes in preventive gastroenterology, colorectal cancer screening, and minimally invasive endoscopic procedures. He completed his fellowship at Sunrise Health GME in Las Vegas and previously trained in internal medicine at St. Vincent’s Medical Center in Connecticut.
A granuloma is a small lump made of immune cells that forms when the body fights infection or inflammation. In the intestines-either the small or large bowel-granulomas are benign but can mimic other conditions such as Crohn's disease.
He reviews your symptoms, medical and family history, and risk factors, then performs a focused abdominal and rectal exam.
We check for markers of inflammation or infection, including complete blood count (CBC), C-reactive protein (CRP) and tests for TB or parasites.
This is the gold standard. During colonoscopy, Dr. Chadha takes targeted tissue samples to confirm granulomas under the microscope (ICD-10 Code: K63.5).

It's a small lump of immune cells that forms in the intestine when the body fights infection or inflammation.
Most often Crohn's disease, but also infections (like TB or parasites), certain medications, or autoimmune diseases such as sarcoidosis.
Many people have no early signs. When symptoms occur, they may include stomach pain or cramps, ongoing diarrhea or constipation, blood or mucus in stool, unexplained weight loss, fatigue, or low-grade fever.
Through a detailed health history and exam, blood tests, CT or MRI imaging, followed by colonoscopy and biopsy, which is the definitive test for granulomas.
Granulomas themselves are not cancerous. However, they can signal a more serious condition like Crohn's disease or an infection that requires treatment.
No. Granulomas are benign. But long-term intestinal inflammation may slightly increase the risk of colon cancer over time.
Only a tissue biopsy from the colonoscopy can confirm that the lesion is a granuloma and not cancer.
Some patients feel relief within a few weeks of starting therapy, but others-especially those with underlying conditions-may need longer-term management.
Yes. A soft, low-fiber diet during flare-ups, good hydration, probiotics, stress-reduction techniques like yoga or deep breathing, and other lifestyle adjustments can ease symptoms.
