A Taichung man taking incretin injections for diabetes developed dehydration, low blood pressure and dangerously low sodium after adding slimming pills containing a diuretic and thyroid hormone.
A diabetic man in Taichung almost traded one health problem for another after taking slimming medication on top of his existing treatment, according to a report from Newtalk and comments from physician Chang Chun-cheng of Dajia Li General Hospital.
The patient, who is in his forties, weighs more than 100 kilogrammes and stands over 180 centimetres tall, had previously brought his blood sugar under control with incretin-based injections, which help slow stomach emptying and reduce appetite, together with diabetes medicines. His condition had been stable for around two years, with regular blood tests showing normal readings, until he sought additional weight-loss pills from a neighbourhood clinic.
That decision led to dizziness, low blood pressure, low sodium levels and a renewed spike in blood sugar. Chang found that the slimming pills contained a diuretic and thyroid hormone, which increased fluid loss and triggered diarrhoea, leaving the man dehydrated and short of sodium. He was admitted to hospital with an electrolyte imbalance and hyponatraemia, the medical term for abnormally low sodium in the blood.
The hospital stopped the weight-loss drugs and treated him with intravenous fluids and medication to correct the imbalance. After discharge, he was told to focus on diet control rather than relying on pills, and his blood sugar gradually returned to normal.
Chang warned that combining so-called “slimming injections” with weight-loss tablets can be highly risky. Incretin medicines are widely used in diabetes care and can support weight reduction, but adding pills that contain diuretics or thyroid hormone can raise the danger of dehydration, abnormal heart rhythms, heart failure and, in severe cases, sudden death.
Independent medical guidance backs up that warning. The U.S. National Library of Medicine says diuretics and laxatives are not approved for rapid weight loss and can cause dangerous dehydration and electrolyte problems. The Mayo Clinic likewise says liotrix, a thyroid-hormone combination, should not be used to treat obesity or to lose weight, while Drugs.com warns that using thyroid hormone such as Tirosint for weight loss in people with normal thyroid levels can be life-threatening.
Chang said the case underlined a broader point: safe weight loss depends on long-term changes in eating habits and exercise, not on chasing the quickest result on the scale.
