Çölyak Hastalığı Olan Bir Kadında Tirzepatid Tedavisi Sonrası Gelişen Şiddetli Diyare

Year 2026, Volume: 10 Issue: 1 , 112 - 115 , 30.04.2026

Abstract

Glukagon benzeri peptid-1 (GLP-1) ve glukoz bağımlı insülinotropik polipeptid (GIP) reseptörlerinin dual agonisti olan Tirzepatid,
glisemik kontrol ve kilo kaybında belirgin etkinlik göstermiştir ancak sıklıkla gastrointestinal yan etkilerle ilişkilendirilmektedir.
Çölyak hastalığı olan hastalarda kullanımına ilişkin güvenlik verileri sınırlıdır. Kilo yönetimi amacıyla başlanan 2,5 mg'lık ilk tirzepatid
dozundan hemen sonra şiddetli sulu diyare gelişen, sıkı bir glutensiz diyetle kontrol altında olan 40 yaşında bir kadın çölyak hastasını
sunuyoruz. Hasta, dehidrasyon ve halsizliğin eşlik ettiği, intravenöz sıvı replasmanı gerektiren, günde on keze varan diyare atakları
yaşamıştır. Laboratuvar değerlendirmesinde hafif hipokalemi ve yüksek AST saptanmıştır. Herhangi bir enfeksiyöz veya diyetsel
tetikleyici tanımlanmamıştır. Tirzepatid tedavisi sonlandırılmış ve semptomlar tamamen düzelmiştir. Gastrointestinal intolerans,
tirzepatidin bilinen ve doza bağlı bir yan etkisidir ancak başlangıç dozunda bu denli akut ve şiddetli reaksiyonlar nadirdir. Mevcut çölyak
hastalığı, değişmiş bağırsak mukozası veya immün mekanizmalar yoluyla enterik yan etkilere duyarlılığı artırmış olabilir. Bu olgu, çölyak
hastalarında düşük dozlarda bile tirzepatide karşı şiddetli gastrointestinal intolerans potansiyelini vurgulamaktadır. Önceden var olan
gastrointestinal bozukluğu olan hastalara tirzepatid reçete edilirken dikkatli izlem ve bireyselleştirilmiş risk değerlendirmesi önerilir.

Severe Diarrhea Following Tirzepatide Therapy in a Woman with Celiac Disease

Year 2026, Volume: 10 Issue: 1 , 112 - 115 , 30.04.2026

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.
