Weight Drugs Fail Many: The Hidden Side
19 Feb
Summary
- 9-15% of users see no significant weight loss from drugs.
- Side effects include nausea, vomiting, and constipation.
- Some individuals found traditional methods more effective.

Injectable weight-loss drugs, including Ozempic, Wegovy, and Mounjaro, have gained significant traction, with an estimated 1.6 million people in the UK reportedly using them. Despite their efficacy for many, studies reveal that 9-15% of participants do not achieve significant weight loss due to genetics, hormones, or side effects. Boris Johnson and Prue Leith are among those who have spoken about adverse reactions or lack of results.
Miranda Levy shared a brutal experience with Mounjaro, suffering severe nausea and constipation, leading her to abandon the drug. She later found success with the Mediterranean diet and exercise, losing half a stone. Clare Martin also experienced persistent sickness and even fainted after taking Mounjaro, ultimately deciding to stop the medication. Annelies Bristow found Ozempic ineffective, losing only a stone over several months before quitting due to a shortage and achieving greater success with Slimming World.
Suzanne Young struggled with Wegovy, finding it destroyed her relationship with food and led to weight regain. She returned to a high-protein diet and exercise, which had worked for her previously. Dr. Kieran Seyan from Lloyds Pharmacy Online Doctor advises that side effects like nausea and dizziness can occur, especially with rapid dose increases or low calorie intake. He stresses the importance of consulting a doctor if side effects are intolerable or progress is slow, noting that underlying conditions can also impact weight loss.
