Lymphocytic duodenitis is a mild inflammation of the duodenum (the first part of the small intestine) caused by an excess buildup of lymphocytes in the intestinal lining. Although the mucosa may look normal on endoscopic exam, biopsy reveals increased intraepithelial lymphocytes. When it leads to malabsorption, it's often coded as ICD-10 K90.41.
He asks about your symptoms, dietary habits, and any family history of gut problems.
These check for celiac disease markers (eg, tissue transglutaminase antibodies) and assess key nutrient levels.
A tiny camera examines the duodenal lining and Dr. Chadha takes a small tissue sample. The lab then counts lymphocytes-fewer than 25 per 100 cells is normal.
He reviews your biopsy results in detail, explains what they mean, and answers all your questions to guide treatment.

Celiac disease (even without full villous damage), autoimmune disorders, gut infections, certain medications (NSAIDs or PPIs), or sometimes no clear trigger is found.
It's generally mild but can lead to malabsorption and fatigue if untreated.
Under 25 lymphocytes per 100 epithelial cells is considered normal.
Yes. Many patients show early celiac changes without complete villous atrophy.
ICD-10 code K90.41 is used when lymphocytic duodenitis is associated with malabsorption.
Yes. Adopting a gluten-free or gluten-light diet, eating lean proteins and cooked vegetables, and staying hydrated often improves symptoms.
