You may have just started to think about weight-loss surgery. Or you may have already made the decision to have surgery. Weight-loss surgery can help you:
It is important to understand that there will be many other changes in your life. These include the way you eat, what you eat, when you eat, how you feel about yourself, and much more.
Weight-loss surgery is not the easy way out. You will still need to do the hard work of dieting and exercising.
Weight-loss surgery can help train you to eat less. But surgery is only a tool. You still have to make the right food choices.
As you lose weight quickly over the first 3 to 6 months, you may feel tired or cold at times. You may also have:
These problems should go away as your body gets used to the weight loss and your weight becomes stable. It is important that you follow your doctor's recommendations on eating enough protein and taking vitamins.
You may become sad after having weight-loss surgery. The reality of life after surgery may not exactly match your hopes or expectations before surgery. You may be surprised that certain habits, feelings, attitudes, or worries may still be present.
Complications, or a slow recovery from surgery, or all the follow-up visits may conflict with the hope that everything was going to be better and easier afterward.
You will be on a liquid or puréed foods diet for 2 or 3 weeks after surgery. You will slowly add soft foods and then regular foods to your diet. You will likely be eating regular foods by 6 weeks.
At first, you will feel full very quickly, often after just a few bites of solid food. The reason is that your new stomach pouch will hold only a tablespoonful of food soon after surgery. Even when your pouch is larger, it will not hold more than about 1 cup of chewed food. (A normal stomach can hold up to 4 cups of chewed food.)
Once you are eating solid food, each bite must be chewed very slowly and completely, up to 20 or 30 times. Food must be smooth or puréed before swallowing.
You will need to drink up to 8 glasses of water or other liquids that do not have calories every day.
After surgery, your doctor, nurse, or dietitian will teach you about foods you can eat and foods to avoid. It is very important to follow your diet. Eating mostly protein, fruits, vegetables, and whole grains will still be the best way to lose weight and keep it off.
You will still need to stop eating when you are full. Eating more after you are full will stretch out your pouch and reduce the amount of weight you lose.
You will still need to avoid foods that are high in calories. Your doctor or dietitian will likely tell you:
It is important to get all of the nutrition you need without eating too many calories. Because of the quick weight loss, you will need to be careful that you get all of the nutrition and vitamins you need as you recover.
If you have gastric bypass surgery, you will need to take extra vitamins and minerals for the rest of your life.
You will need regular checkups with your doctor to follow your weight loss and make sure you are eating well.
After losing so much weight, you can expect changes in your body shape and contour. These changes may include excess or saggy skin and loss of muscle mass. The more weight you lose, the more excess or saggy skin you will have. Excess or saggy skin tends to show most around the belly, thighs, buttocks, and upper arms. It may also show in your chest, neck, face, and other areas as well.
