After countless years of dieting and exercising, the dream of extreme weight loss might still seem very distant. Weight loss through gastric sleeve surgery may be the way of life of obese people, quite literally. Moreover, if you happen to be the one searching for a permanent solution to weight loss, you do not need to spend a fortune. The emergence of medical tourism has opened up the opportunity for you to have a few options in other countries with good hospitals and accomplished surgeons delivering gastric sleeve surgery at a fair price.
What is a Gastric Sleeve?
Gastric sleeve or sleeve gastrectomy is a weight loss bariatric surgery which is done by the reduction of the patient's stomach. The word “gastrectomy” is a medical term that denotes the removal of any part of the stomach. In the gastric sleeve operation, the majority of the stomach, i.e. almost 80 percent is removed and a “sleeve” or a tube which is roughly the size of a banana, is the one that remains.
What Kind of Health Problems Does the Gastric Sleeve Procedure Address?
Gastric Sleeve Surgery is a surgical procedure for weight loss and the treatment of various ailments triggered by obese patients’ overweight status. This surgery is only pursued by qualified candidates having severe health complications or those liable to develop health complications due to morbid obesity. Gastric Sleeve surgery relieves or eliminates various health disorders including:
- Insulin resistance and Type 2 Diabetes.
- Hypertension and heart failure caused by hypertension.
- Hyperlipidemia (excess cholesterol) and atherosclerosis
- Nonalcoholic fatty liver disease and steatohepatitis
- Obesity hypoventilation syndrome and obstructive sleep apnea.
What Requirements Are Needed for a Gastric Sleeve Surgery?
The main criteria for permission to be allowed were:
That you have severe obesity (class III). It is diagnosed according to your BMI (body mass index) based on your weight and height and associated health issues. In class III, you have a BMI of 40 or more, or 35 with an associated health condition and one other associated health issue.
That you have attempted, but were not successful, at losing weight before undergoing the surgery. You might need to follow a medically guided weight loss program for three to six months before insurance will authorize and cover the surgical costs.
To ensure that you are physically and mentally ready to undergo the surgical and post-operation procedures. Prior to becoming eligible for weight loss surgery, you would have to attend counseling sessions conducted by a panel of dietitians, psychologists, and other professionals.
Preparing for a Gastric Surgery
Stop Smoking
There are various ways through which smoking hinders the process of healing. Firstly, the substances in smoke obstruct your circulation, making it difficult for your body to provide oxygen and nutrients in order to heal. Secondly, smoking impedes your immune system in such a way that your body cannot fight germs.
Introduce New Eating Habits
Just like any other form of bariatric surgery, gastric sleeve surgery is known to change your eating habits quite radically. Prior to the surgery, our team of experts usually advise their patients on the need for an alternate eating routine, including the possibility of relying on a specialized diet like a liquid diet for some few weeks prior to the surgery.
Acquaint Yourself with your New Diet Program
Talking about new behaviors related to eating, this would be the best opportunity to carefully go through everything you need to eat after surgery and understand everything about it too. Questioning each and every thing would really help in getting your brain and body ready for this new routine. It is true that you will be on a liquid diet, however, it would be the right moment to start looking into the recipes of someone who has had bariatric surgery.
Prep Your Kitchen
Preparing for the changes in your diet due to the surgery can also be accomplished by filling your pantry with food products that are in line with your new dietary restrictions. You should concentrate on the type of food that you will be able to eat after your operation so that you do not have to think about it at the time of your surgery. You also use this opportunity to get the bad food out of your kitchen when you're not able to eat it anyway.
Prep Your Home
Get all the essentials household tasks out of the way prior to the operation, and if it is feasible, make the arrangement with your family members or friends to help you with the household tasks and anything else you may require during the time of your recovery. Also, be sure that you have ample time after the surgery for rest and recuperation.
Expand Your Wardrobe
A change in the dimensions and the figure of the body is what happens to the body while it is losing weight. Weight loss may occur at different speeds, and if one still has a couple of “flexible” pieces of clothing, there is no need to be in doubt of what to wear when losing weight on the way.
Support and Help Resources
In case your weight is excessively high, a bariatric operation might indeed be a good solution for you, but it also entails major changes. Such groups for bariatric support are a place where you can find people with the same background as you and who have also experienced the same kind of surgery. There is no better psychological support than that from the people who know and understand your difficulties.
What is Expected During the Surgery?
During surgery, you will be under general anesthesia. This will make you very deeply sedated, and you will not be aware of what is going on. The laparoscopic method will usually be the one your doctor will use to do the surgery. There will be a few small cuts made in the upper belly by the doctor. Through these cuts the doctor will insert a thin tube, known as a laparoscope, and other small surgical instruments. In case it is impossible to carry out the surgery with laparoscope in a safe manner, it will have to be done by making an open incision.
The anesthesiologist will then pass a small tube through your mouth down into the stomach. The surgeon will then use a laparoscopic stapler to divide the stomach, leaving a narrowed vertical sleeve. The part of the stomach that was removed is then taken out of the abdomen through an incision. Your surgeon may then test for any leaks in the sleeve using a dye study or an upper endoscopy.
