Proton Pump Inhibitor (PPI)-Domperidone Induced Anemia and Galactorrhea: A Case Report
Abstract
Gastrointestinal disorders are increasingly common among young adults, particularly medical students exposed to chronic stress and irregular dietary habits. Proton pump inhibitors (PPIs) are widely prescribed for the management of gastroesophageal reflux disease (GERD), gastritis, and related acid-peptic disorders. However, prolonged PPI therapy has been associated with impaired iron absorption and may contribute to iron deficiency anemia (IDA). We report the case of 26-year-old female, unmarried, postgraduate medical student with iron deficiency anaemia and galactorrhea. The patient presented to gastroenterology clinic with a complaint of mild non-colicky epigastric pain, nausea, fatigue and shortness of breath. Comprehensive evaluation included complete blood count with peripheral smear, iron profile study, stool routine and stool for occult blood, serum IgA anti TTG, viral markers, upper gastro intestinal endoscopy (UGIE) & biopsy, H. Pylori ammonia breath test, gastric emptying scintigraphy, USG abdomen and pelvis, and serum prolactin levels. Based on the clinical, laboratory, and radiological findings, a diagnosis of iron deficiency anemia secondary to long-term PPI use and domperidone-induced galactorrhea was established. The patient was treated with intravenous ferric carboxymaltose (1500 mg), advised discontinuation of PPI-domperidone therapy, and initiated on a low-FODMAP diet. Significant clinical and hematological improvement was observed on follow-up, along with…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
