I have become tummy speialist after answering so many tummy questions. Why do people gain weight in this part only? Well, our lifestyle is responsible. Well, Meenakshi there are many cosmetic surgery procedures for this. So, you dont have to worry much. However, these are quite expensive things. But there are simple methods too to losew eight. Join a gym, go for swimming etc. Also, leave high carb foods and have light food, less calories can help you.
