Documented weight effects of Glucophage
Whether Glucophage causes weight gain, loss or no meaningful change depends on Metformin and how it acts. Some medications in Diabetes Treatment affect appetite directly; others alter fluid balance, metabolic rate, or sleep — all of which can shift weight. The prescribing information lists weight effects observed in clinical trials.
Practical management
Modest weight changes (±1–3 kg) over the first months on Glucophage at 500mg, 850mg, 1000mg are common and often resolve without intervention. Larger or distressing changes deserve a discussion with the prescriber. According to general clinical guidance, the right response is not always to stop Glucophage — diet, activity, sleep and addressing the underlying condition all matter.
