Hi
She is having symptoms of pcos.That is why she is obese.
You can get your sister examined by an endocrinologist also to rule out other causes for obesity like
thyroid problems etc.
Regarding loosing weight she should modify her food habits along with exercises.she can take the help of a dietician and join a gym or yoga centre.
You can discuss this with your gynaecologist or endocrinologist. all the best
