Tirzepatide use in non-diabetic obese patients can induce severe ketoacidosis, primarily through starvation ketosis driven by gastrointestinal side effects and reduced caloric intake, rather than diabetic mechanisms.

If you are using tirzepatide for weight loss, do not buy it over the counter without medical oversight. Be aware that severe nausea, vomiting, or diarrhea combined with low food intake can lead to dangerous acid buildup (ketoacidosis), even if you do not have diabetes. Seek immediate medical attention if you experience abdominal pain, vomiting, and rapid breathing.

We report the first case of ketoacidosis after the use of tirzepatide in an obese non-diabetic patient, secondary to the possibility of starvation ketoacidosis and insulin resistance.
