Documented weight effects of Lumigan
Whether Lumigan causes weight gain, loss or no meaningful change depends on Bimatoprost and how it acts.

Practical management
Modest weight changes (±1–3 kg) over the first months on Lumigan at 0.01%, 0.03% 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 Lumigan — diet, activity, sleep and addressing the underlying condition all matter.
