Question: can diazepam make you lose weight?
Answer: Other research has suggested that when taken in the longer term, a change in the dosage of diazepam (Valium) does affect weight (Frisbie, & Aguilera, 1995). Specifically, the research found that taking diazepam (Valium) for up to 10 months led to weight gain while cessation of diazepam (Valium) led to weight loss.
