Who Needs Bariatric Surgery?
Bariatric surgery may be an option for you if you meet the following criteria:
"Extreme obesity" refers to a body mass index (BMI) of 40 or greater.
Obesity is defined as a BMI of 35 to 39.9, and you have a primary weight-related health concern, such as type 2 diabetes, high blood pressure, or severe sleep apnoea. Suppose your BMI is between 30 and 34, and you have significant health issues due to your weight. In that case, you may be eligible for specific weight-loss surgery in some circumstances.
Everyone who is highly overweight may not benefit from bariatric surgery. For weight-loss surgery, you must meet specific medical requirements. You will likely undergo a screening process to determine your eligibility. You must also make long-term changes to live a healthier lifestyle. Long-term follow-up plans involving the observation of your dietary habits, way of life, conduct, and health issues may be expected of you.
How Do You Prepare for Bariatric Surgery?
Your medical team provides you with preparation guidelines for your particular type of surgery if you are a candidate for bariatric surgery. Several lab tests and exams may be required before surgery. There could be limitations on what you can eat, drink and which drugs you can use. You might have to give up smoking and begin an exercise regimen. You might also need to prepare by organising your post-surgery rehabilitation in advance. For example, if you believe you will want assistance at home, make arrangements for it.
What Can You Expect during the process of Surgery?
Bariatric surgery is performed at a hospital under general anaesthesia. This means you are unconscious during the process. Your condition determines the specifics of your surgery, the type of weight-loss surgery you have, and the hospital's or doctor's practices. Traditional extensive abdominal incisions are used for several weight-loss procedures. This is known as open surgery.
The majority of weight loss surgeries are now done laparoscopically or through key-hole procedures. A laparoscope is a small, tubular tool that includes a camera. The laparoscope is placed into the abdomen through tiny incisions. The tiny camera on the tip of the laparoscope lets the surgeon see and operate inside the belly without significant incisions. Read the blog on 'Guide to Weight Loss Surgery' to get a detailed knowledge on the subject.
Treatment and Procedures
The surgical weight-loss technique is known as a sleeve gastrectomy or vertical sleeve gastrectomy. This treatment is usually done laparoscopically, which includes introducing small instruments through several small incisions in the upper belly.
Approximately 80% of the stomach is removed during a sleeve gastrectomy, leaving behind a tube-shaped, banana-sized stomach. Your stomach's capacity for food determines how much you can eat. In addition, the process induces hormonal changes that aid in weight loss. Obesity-related diseases, including high blood pressure and heart disease, are treated with the help of these hormonal adjustments.
The specifics of your sleeve gastrectomy will differ depending on your unique circumstances and the hospital's or doctor's practices. Although sleeve gastrectomy is frequently carried out laparoscopically, some treatments may require conventionally large abdominal incisions. With the help of tiny incisions in the upper belly, the surgeon can introduce tiny instruments using this minimally invasive approach. The average length of the procedure is one to two hours.
Bariatric Surgeons in Millers Road, Bangalore will closely watch you in a recovery room after the procedure while you awaken there. You can be confident that their attentiveness and concern will contribute to your safe recovery and well-being. Your diet after having a sleeve gastrectomy starts with sugar-free, noncarbonated drinks for the first seven days, then shifts to pureed foods for the following three weeks, and eventually, ordinary foods around four weeks after the procedure. For the rest of your life, you must take a multivitamin twice daily, a calcium supplement once daily, and a vitamin B-12 injection once a month.
Mini Gastric Bypass (MGB) is a weight-loss surgery that combines restrictive and malabsorptive techniques to help patients achieve significant weight loss. During the procedure, the surgeon creates a small, tube-like stomach pouch and then connects it directly to the small intestine, bypassing a portion of the stomach and the upper part of the small intestine. This results in reduced food intake and decreased absorption of calories and nutrients.
Mini Gastric Bypass surgery is typically performed laparoscopically, using small incisions and specialised instruments. It offers the advantages of shorter operative time, more superficial anatomy, and potentially more significant weight loss compared to traditional gastric bypass surgery.
You will be administered general anaesthesia before the mini-gastric bypass procedure. Your surgeon makes many small incisions on your abdomen. They will carefully inspect your internal organs on a monitor after inserting a laparoscope, a little instrument with a light and camera on end, into one of the incisions. Tiny surgical instruments are placed via the other incisions to accomplish the surgery. Stapling transforms the stomach into a long, slim pouch up to the antral portion.
Making a bypass so that food can flow from the new stomach pouch is the second part of the procedure. Depending on the surgeon's preference and the patient's metabolic status, a small intestinal loop with a preferred length of 150 to 250 cm is selected for anastomosis. It is known as the "omega loop" because the centre portion of the intestine is connected to the opening in the stomach pouch. Food can go through the loop, bypassing the duodenum, lower stomach, and a section of the small intestine. The incisions are sutured closed at the end of the surgery.
Gastric bypass, sometimes called Roux-en-Y (roo-en-wy) gastric bypass, is a weight-loss procedure that entails cutting a tiny pouch out of the stomach and attaching it straight to the small intestine. Following a gastric bypass, most of your stomach and the first part of your small intestine is bypassed as the food you swallow goes through this tiny pouch of your stomach and straight into the small intestine.
The gastric bypass procedure is used when diet and exercise have failed or when you are experiencing significant health issues due to your weight. Gastric bypass is not appropriate for everyone who is exceedingly overweight. To determine your eligibility, you should go through a thorough scream to determine your eligibility. You must make adjustments to live a healthier lifestyle.
Gastric bypass surgery is a complex procedure that involves various stages. Before the surgery, you will receive general anaesthesia to ensure you are unconscious and comfortable throughout the operation. The specifics of the surgery will depend on your circumstances and the surgeon's practices.
While some surgeries may involve large incisions, most gastric bypass procedures are performed laparoscopically using small incisions. During the surgery, the surgeon creates a small pouch at the top of your stomach by sealing it off from the rest of the stomach. This pouch can hold only a tiny amount of food. Next, a portion of the small intestine is cut and attached to the pouch, bypassing the more significant part of the stomach and the initial section of the small intestine. This allows food to enter the middle part of the small intestine.
The surgery typically lasts a few hours after which you will awaken in a recovery room where medical professionals will monitor you for any complications. The post-surgery period gradually transitions from liquids to pureed foods to softer and firmer foods as your body heals. You must follow dietary restrictions and may require vitamin and mineral supplements to ensure proper nutrition.
After gastric bypass, your body may undergo various changes as it adapts to rapid weight loss, including body aches, fatigue, coldness, dry skin, hair thinning, hair loss, and mood changes. Regular checkups, laboratory testing, and medical examinations will be necessary to monitor your health and ensure a successful recovery. It is very crucial to discuss all aspects of the surgery, including potential risks and long-term commitments, with your healthcare provider to make an informed decision and receive appropriate post-operative care.
Revisional Bariatric Surgeries
When further intervention is needed after bariatric surgery due to certain complications or not up to the mark results, the surgeons may perform revisional bariatric surgeries. These procedures aim to address the specific problems or concerns faced by patients who have previously undergone bariatric surgery. More complex than typical bariatric surgeries, these require careful assessment and personalised planning. If you are considering a weight loss surgery, Please go through the guidelines documented by our specialists.
Some common revisional procedures performed include the following:
Stomach Pouch Resising - If the stomach pouch has stretched over time, the surgeons may suggest resizing it to restrict food intake and improve weight loss.
Stoma or Anastomotic Revision - If the opening connecting the stomach pouch to the small intestine has become too wide, revisional surgery may be needed to enhance weight loss.
Correction of Anatomical Abnormalities - Revisional surgeries may address anatomical issues contributing to complications or inadequate weight loss, such as hernias, bowel obstructions, or intestinal strictures.
Addressing Nutritional Deficiencies - Some revisional surgeries may involve interventions to address nutritional deficiencies. These deficiencies may result from the initial bariatric procedure, such as improving nutrient absorption or supplementation strategies.
Bariatric Reversal Surgeries
Bariatric reversal surgeries are performed to reverse or undo a previous bariatric procedure. The surgeons recommend these for individuals who have experienced significant complications, intolerable side effects, or unsatisfactory weight loss after their initial weight loss surgery. Such surgeries aim to restore the normal anatomy and functionality of the gastrointestinal tract.
Commonly performed bariatric reversal procedures include the following:
Removal of the Adjustable Gastric Band
The gastric band placed initially by the surgeon is removed. The complications like band slippage, erosion, or inadequate weight loss may necessitate this procedure.
Conversion to a Different Bariatric Procedure
This involves converting one bariatric weight loss surgery to a different type of bariatric procedure. For example, gastric bypass, sleeve gastrectomy, etc., are the procedure that can be performed.
Gastrectomy or Partial Gastrectomy
This type of reversal surgery can entail removing a portion of the stomach or converting it back to its former properties. This procedure is recommended if there’s significant weight regain in a patient who had previously gone through sleeve gastrectomy.
Intestinal reconnection or reconstruction
Such procedures are typically done to restore the normal flow of food and digestive juices. The surgeon reroutes or bypasses a section of the small intestine.
Removal of Gastric Bypass Components
The surgeon reverses the gastric bypass either by removing a gastric bypass pouch or reattaching the small intestine to the stomach.
After Bariatric Surgery
You will not be able to eat for 1 to 2 days after weight-loss surgery to allow your stomach and digestive system to heal. After that, you will adhere to a strict diet recommended by our dietician for a few weeks.
The diet starts with simple liquids, then moves on to pureed diet and highly soft foods, and then to ordinary foods. There may be several restrictions or limits on how much and what you can eat and drink. In the first few months after weight-loss surgery, you will also have regular medical exams to monitor your health which includes laboratory testing, blood work, and other exams.
Long-term weight loss can be achieved with gastric bypass and other bariatric operations. The type of surgery you have and the modifications you make to your lifestyle will determine how much weight you lose. Losing half or more of your excess weight in two years is feasible.
Gastric bypass surgery has the potential to alleviate or treat several conditions that are associated with morbid obesity, such as:
High blood pressure
Obstructive sleep apnoea
Type 2 diabetes
Nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH)
Gastroesophageal reflux disease (GERD)
Joint pain, also called osteoarthritis
Polycystic Ovarian Syndrome (PCOS).
In addition to enhancing your ability to carry out daily tasks, gastric bypass surgery may also enhance your quality of life.
When Weight-loss Surgery Isn’t Helping
It is possible that you will not lose weight and that you are likely to experience severe health issues if a weight-loss surgery doesn't work or stops working. Maintain all planned follow-up appointments following weight-loss surgery. Consult your doctor immediately if you are not losing weight or if you experience issues.
Tracking your weight loss enables you to look into problems that may keep you from losing weight. Any weight-reduction surgery has the risk of inadequate weight loss or weight gain even when everything goes according to plan. You may gain weight if you do not make the essential lifestyle changes, such as getting regular physical activity and eating healthy meals.
