GLP-1 receptor agonists (semaglutide, tirzepatide) can cause excessive appetite suppression leading to restrictive eating behaviors, severe caloric restriction, dehydration, and acute kidney injury, particularly in unmonitored or high-risk populations.

If you are prescribed a GLP-1 agonist (like Ozempic or Mounjaro), do not use it without medical supervision. Ensure you are screened for eating disorders and receive dietary counseling. Watch for signs of extreme food aversion or dehydration, and stop the medication if you lose weight too rapidly or feel severe nausea/diarrhea, seeking immediate medical attention if you experience kidney issues.

ModerateQualifiesMEDIUM confidence
These cases highlight the complexity of appetite regulation and the need for careful monitoring when using these medications... [Case 3] reported severe diarrhea and reported the loss of almost all sense of hunger and thirst, stopping nearly all liquid intake... Laboratory evaluation of renal function revealed their creatinine had increased from 0.6 to 3.6 mg/dL, prompting hospitalization for acute kidney injury and treatment for dehydration and electrolyte deficiencies.
