Should you fast during Ramadan if you are taking GLP-1 medications for weight loss or diabetes?

UAE doctors say you can fast in some cases, but only with medical supervision, because GLP-1 therapies can suppress appetite and thirst, slow digestion and, when combined with fasting and other glucose-lowering drugs, may increase the risk of hypoglycaemia, dehydration and muscle loss; specialists recommend a pre-Ramadan consultation, adjusting dose and timing (weekly injections are generally better taken after iftar once rehydrated and fed, while oral forms are usually taken at suhoor on an empty stomach), focusing on protein-rich meals, steady hydration between iftar and suhoor, and breaking the fast immediately if blood sugar drops too low or severe symptoms like dizziness, vomiting or abdominal pain occur — in some cases, patients may be advised not to fast at all for safety. Do you think more people should get a medical check before fasting while on weight-loss or diabetes medications?
