A 37-year-old mortuary technician, Hayleigh Davis, has been diagnosed with anorexia following an addiction to weight-loss injections. Davis, who lost eight stone after beginning the regimen in November 2024, reports that the misuse of the medication led to severe physical complications, including gallbladder issues and kidney damage, ultimately requiring professional intervention at an eating disorder clinic.
How weight-loss injection misuse leads to clinical eating disorders
The transition from medical weight management to psychological dependency often begins with the rapid suppression of appetite. According to Davis, the injections initially served as a tool for weight loss, but the fixation on the scale soon replaced healthy nutritional habits. By increasing her dosage to two or three times the recommended weekly frequency, she entered a cycle of restrictive eating. Medical experts at Beat Eating Disorders note that such behaviors can trigger or exacerbate underlying predispositions to anorexia, as the brain struggles to recalibrate hunger cues even after the medication is discontinued.
Clinical guidelines for GLP-1 receptor agonists emphasize that these medications are intended as an adjunct to diet and exercise, not a replacement for caloric intake. Misuse, defined as exceeding prescribed doses, significantly increases the risk of metabolic crash and electrolyte imbalances.
The physical and mental toll of rapid weight loss
Davis experienced a range of severe side effects that serve as a warning to prospective users. Beyond the mental health impact, she suffered from extreme hair loss, recurrent urinary tract infections that compromised her kidney function, and painful gallbladder flare-ups. These physical symptoms are consistent with rapid, medically unmonitored weight loss. According to accounts provided by Davis, she currently experiences significant anxiety surrounding food, limiting her intake to ice cubes, tuna, and yogurt as part of her recovery process.

What are the long-term risks of off-label medication use?
The primary risk associated with weight-loss jabs is the lack of clinical supervision when individuals source the medication through non-traditional channels. Davis admitted to sourcing the injections through friends to bypass standard medical oversight. Healthcare professionals warn that without a GP monitoring blood work and mental health markers, users may fail to recognize the signs of malnutrition or psychological distress until they are in a “very poor way physically,” as Davis described her own experience of fainting and illness.
Pro tips for safe weight management
- Consult a GP: Never start weight-loss injections without an official prescription and regular follow-ups.
- Monitor Mental Health: If you find yourself fixating on the scale or feeling extreme anxiety about food, seek support immediately.
- Follow Prescribed Dosages: Increasing frequency does not speed up healthy fat loss; it only increases the risk of severe side effects.
- Set Exit Strategies: Discuss a clear plan with your doctor for when to stop the medication once target goals are reached.
