This condition refers to changes in your small intestine after surgery. During an intestinal bypass, part of the intestine is removed or skipped. Doctors then connect the remaining segments with a new link called an anastomosis. It's often done to treat disease or aid in weight loss. (ICD-10 code: Z98.84)
He reviews your surgical records, current symptoms (pain, diarrhea, weight changes) and examines your abdomen for tenderness or distension.
Panels check for anemia, vitamin D, B12 and iron deficiencies, protein levels and electrolyte imbalances that often accompany malabsorption.
Analysis for infection, inflammation markers, and fecal fat helps rule out bacterial overgrowth and quantify malabsorption.
An upper endoscopy or balloon-assisted enteroscopy allows direct visualization of the anastomosis site, helping identify ulcers, strictures or marginal leaks.
