The use of GLP-1 medications like Ozempic for weight loss is sparking intense debate, as many users report 'absolutely horrid' side effects like nausea, constipation, and constant vomiting, yet insist the significant weight loss results are worth the suffering. However, not everyone is convinced, with nearly half of users seeing no weight loss despite drastic appetite changes, and concerns raised over serious risks like dehydration and blood loss.

Why it matters

This controversy highlights the ethical dilemma of promoting drugs that deliver dramatic weight loss results at such a high cost to users' well-being. It raises questions about whether the long-term benefits outweigh the short-term misery, and whether it's appropriate to market these medications given the potential dangers.

The details

Despite reports of debilitating side effects, two-thirds of users who experienced weight loss, suppressed appetite, or reduced food cravings gave GLP-1 medications high marks. However, nearly everyone faced at least one of the five most common side effects - nausea, stomach pain, vomiting, diarrhea, or constipation. Some even saw these effects as a silver lining, claiming they helped break bad habits. Yet, about half of users noticed drastic appetite changes but saw no weight loss, prompting them to quit. Researchers have also flagged more serious risks like dehydration and blood loss among users who gave lower ratings.

  • A study on the effects of GLP-1 medications was published in the Journal of Medical Internet Research in 2026.
