Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain it seems that you are suffering from excess intestinal gas formation and can be due to causes like excess intake of fatty foods, lack of physical activity, eating too fast, smoking, frequent chewing of chewing gums and sucking candies,constipation, food intolerance, diseases like Crohn s disease, Irritable bowel syndrome, lactose intolerance etc.. As your ultrasound report is normal you need not to worry as you will get relieved soon.. Yo can take Simethicone as it helps in reducing excess intestinal gas. You should take small portions of food every 2 hours and avoid eating fatty meals and in bulk.. You should always take walk after meals.. You should start doing moderate workout.. Eat slowly and chew well.. You should drink plenty of water.. Seep atleast 2 hours after meals.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
