You have a certain amount of fat around your organs inside your belly. You also have an apron of fat that goes over your organs and around your intestines called the omentum. This is made up mostly of fat. If you carry excess weight, often the omentum and the fat around your organs become larger and more fatty. If you have any gas in your stomach or intestines during the day, it can push on that fat and make your abdomen protrude. The best way to deal with this problem is not surgical. it is best to find a good healthy diet and exercise plan. This will help reduce the content of fat inside your abdomen so that your belly will not protrude as much when you have a little extra gas in your intestine or soon after you eat a meal.The best way to diet is to keep a journal and write down everything you eat and drink during the day. Ask you doctor for some healthy meal plans and a healthy daily calorie intake for your current height and weight. Many family practice doctors are more than happy to help with weight loss. Avoid fads and find a buddy that will help you in the times of temptation!!Good luck!! I hope this helps!!
