Severe Diarrhea Following Tirzepatide Therapy in a Woman with Celiac Disease
Abstract
Tirzepatide, a dual agonist of glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptors, has
demonstrated marked efficacy in glycemic control and weight reduction but is frequently associated with gastrointestinal adverse effects.
Data on its safety in patients with celiac disease are limited. We describe a 40-year-old woman with well-controlled celiac disease
on a strict gluten-free diet who developed severe watery diarrhea immediately after the first 2.5 mg dose of tirzepatide, initiated for
weight management. She experienced up to ten diarrheal episodes per day with dehydration and fatigue, requiring intravenous fluid
replacement. Laboratory evaluation revealed mild hypokalemia and elevated AST. No infectious or dietary triggers were identified.
Tirzepatide was discontinued, resulting in complete symptom resolution. Gastrointestinal intolerance is a known dose-dependent adverse
effect of tirzepatide; however, such acute and severe reactions at the starting dose are uncommon. The coexistence of celiac disease may
have increased susceptibility to enteric side effects through altered intestinal mucosal or immune mechanisms. This case highlights the
potential for severe gastrointestinal intolerance to tirzepatide, even at low doses, in patients with celiac disease. Careful monitoring and
individualized risk assessment are recommended when prescribing tirzepatide to patients with pre-existing gastrointestinal disorders.
