My friend name is deepa.. she is also syuding 2nd year bcom.. she is suffering from night bedwet.. she needs some solution... can you help her

Are there medical conditions involved here? Does she bedwet all the time?

There are a lot of factors which can cause this. Some medications, but also lifestyle. If she was out drinking, bed wetting would not be a surprise. Some people find that diet drinks with aspartame cause leaking. Other people find that coffee can be a problem.

Has she had a baby? That can also be a factor.

If she has tried modifying her diet and has done her pelvic floor exercises and still has a problem, then she should speak to her doctor. There are medications which help, and there is an operation which can fix this.
