My colleague experience an episode of pain due to rheumatoid arthritis maybe because she's overweight and her legs can’t take the weight of her body. I was wondering if mefenamic acid or any forms of pain relievers can predispose obesity. What are the long term effects of taking such drugs? Can I possibly request for a liposuction because I tried it before and I don't want to recommend it to a friend without thinking on her safety it might cause complications, if yes. What is the best form liposuction indicated for her? I need your suggestions, thank you.
