What are Different Types of Bariatric Surgeries? 

Bariatric Surgery is one of the most popular options for obese people looking for a way to control their weight. To get bariatric surgery, one has to qualify for certain criteria like BMI (Body Mass Index), associated comorbidities like Diabetes, Hypertension, sleep apnea, infertility, hypercholesterolemia etc. There are many kinds of bariatric surgeries or weight loss surgeries, different surgeries work differently in order to give the desired effect, which is why it is important to understand these surgeries thoroughly. 

Weight loss surgeries are divided into different categories like - 

  Restrictive surgeries: Some bariatric surgeries are focused on limiting the amount of food that can be stored in the stomach. This allows a person to eat less than they used to, because of the limited capacity of the stomach. Sleeve gastrectomy, Adjustable gastric banding, Gastric imbrication, Gastric balloon surgery are examples of restrictive procedures. In sleeve gastrectomy, the stomach is divided into two halves first, then one half of the stomach is completely removed. The remaining part of the stomach is formed into a tube-like structure. This tube-like structure cannot hold enough food and restricts excessive food intake. It also limits the secretion of an appetite hormone called Ghrelin which limits the desire of a person to eat. 

  Malabsorptive procedures: In this procedure, a large segment of the small intestine is bypassed i.e the food is not allowed to enter a large segment of the small intestine and hence malabsorption will be there. Duodenal switch is a malabsorbtive surgery. 

To Summarize: The weight loss procedures that suit our Indian population are the Roux en Y gastric bypass and the sleeve gastrectomy. We do not come across any sign of malnutrition in patients who have undergone these procedures. For successful outcomes, vitamin, calcium and protein supplements are required. 

There are certain myths about bariatric surgery --- life will never be normal after the surgery, pregnancy is a problem after this surgery, one will never be able to eat after this surgery, marriage is a problem after this surgery etc. All these are incorrect as one live a better life after the surgery as one has shed the extra kilos, one is cured of existing problems like diabetes, high cholesterol, hypertension, obesity induced infertility and sleep apnea extra. IN FACT, the quality of life is phenomenal after this surgery. CHOICE of surgery depends on the existing BMI, existing associated problems and results of the investigations that are done prior to the surgery. Your surgeon is the best to decide the right procedure for you. As the procedure which your friend has undergone might not be good for you. Choice of procedure and proper follow up are the key points for a successful surgical outcome. 

  Combination of restrictive and Malabsorptive surgeries: In these procedures, the surgery is done on the stomach as well as the small intestine. It involves creating a small stomach pouch which is attached to the small intestine, thus bypassing a small segment of the small intestine to get the desired effect if the person has diabetes associated. The rest of the stomach produces important digestive juices and is also connected to the intestine so that it can transfer these digestive juices in it. As a part of the stomach and few centimetres of the small intestine are bypassed i.e food does not enter this part, the surgery is called the gastric bypass. The Roux en Y gastric bypass and the Mini Gastric bypass surgeries are examples of these combination procedures.

Bariatric Surgeries - Know Forms Of Them!

Bariatric surgery is unlike other surgeries, as its effects are not instant but gradual and are seen over the months. Like any other surgery, it is not without complication. But again unlike all other surgeries, the complication rate can be negligible if a strict protocol is followed. Moreover, the factors like technology advancements, development in the field of advanced laparoscopy, enhanced skillset of the bariatric surgeon, dedicated management of bariatric and metabolic surgeries by bariatric surgeons, play a vital role in the reduction of complication rate which eventually results in safe surgery.

As the procedure is done laparoscopically, the pain is just for a day and is minimally managed by analgesics.

The fear of increasing incidence of incisional hernias while operating an obese patient is so negligible or nil, as the procedure is performed through tiny key holes and all precautions are taken to suture the sheath through which the ports are put to perform the surgery.

Reduced hospital stay and early resuming to work is one of the biggest benefits of this laparoscopic bariatric procedure.

Sometimes, problems that may be faced are:- 

Post-operative bleeding: Normally, this a nearly bloodless surgery involving 5 to 10ml loss of blood. However bleeding from the staple edges is known, but this can be managed well by the surgeon, by choosing the right size of the cartridge as well the right technique of application of the cartridge.

Dehydration: We are normally accustomed to drinking water at long intervals (a few hours) as we can consume nearly 200 to 400ml at one go. Following bariatric surgery, gulping or drinking water in one go is not possible in the first 2 to 4 weeks, due to reduced capacity of the gastric pouch. Hence, care needs to be taken to drink small quantities of water at frequent intervals to avoid dehydration. This is possible only if the patient is counselled about this prior to surgery and is fully aware of this. Also, the patient needs to be given good and clear post operative instructions regarding the quantity and frequency of liquid consumption, not forgetting the type of liquids. Coffee taken frequently could be another cause for dehydration. Family members and colleagues and friends at work play a major role in reminding tthe patient about consuming water frequently. Special care needs to be taken in people who are not accustomed to consuming adequate quantities of water prior to surgery as a general habit.

Vomiting/Fullness/ Discomfort/Indigestion: Following bariatric surgery, soft food is introduced in the diet in the third week, after the first 2 weeks of taking liquids. Due to the reduced capacity of the gastric pouch, the morsel size is significantly reduced and one has to chew the morsel well and eat slowly, giving a gap of 40 to 50 seconds between the morsels. This prevents distension or overdistension of the gastric pouch and thus avoids vomiting. This again requires good counselling prior to the surgery and on the follow up visit too before stating soft food. There is a subjective difference when we say small morsels and we cannot reach a standardization as the morsels size of each individual varies prior to the surgery itself. The best way to avoid this confusion is to make the person have the first soft food meal before you where in you can physically show the way food is expected to be eaten. However, by mistake, there is a chance that one can have a regular sized morsel as over years one is used to eating in that manner. If this happens, the person will vomit , and this will be a reminder to gauge the morsel size the next time the person eats. Following the vomiting, there could be a burning sensation in the stomach which will subside afer taking an antacid. If one follows the instructions of small morsel size, chewing properly and eating slowly, there is no chance that there will be vomiting. Another reason for vomiting could be keeping the stomach empty for a longer duration or having sicy food on an empty stomach. Avoid nuts, seeds, fried foods and processed foods. Very rarely vomiting could be due to reduced size of the joint between the gastric pouch and the small intestine. This could require an Endoscopy and necessary treatment.

Vitamin and mineral deficiency: It is seen that many of the obese patients are seen to have vitamin B12, vitamin D, iron and protein deficiencies in their blood tests that are done prior to surgery. With the significant reduction in the amount of food consumed after bariatric surgery, the existing deficiencies are bound to increase. Hence, it is necessary to do these tests, before surgery and rectify the deficit prior to the surgery.  

Gall bladder stones: Significant weight loss which is consistant over a short duration could lead to the formation of gall bladder stones, be it with or with out surgery in a small percentage of patients. To avoid this there are two schools of thought, one is have a prophylactic removal of the gall bladder along with the bariatric surgery and another is to put the patient on ursodeoxycholic acid (a tablet) for the first few months after surgery during which there is significant weight loss.

Skin sagging: In the morbidly obese, when the skin is overstretched beyond a certain point, it tends to sag once significant weight is lost. This sagging is influenced by a number of factors like age of the patient, the BMI, pre existing sagging, pre-existing muscle tone and protein supplements taken during weight loss and exercises done during the weight loss period. Skin sagging is less if the age is less than 45, BMI less than 45, good protein intake during weight loss and good toning exercises done during the weight loss period.

Hairfall: Significant weight loss either by diet and exercise, aerobics, bariatric surgery, will entail hair loss. But this can be minimised to a greater extent by ensuring good protein intake during the weight loss period and adequate supplements in terms of vitamins and minerals.

Dumping syndrome: With a reduced size of the stomach, the food moves from the stomach into the smaller intestine much faster. This causes the pancreas to release excessive amount of insulin, leading to very low blood sugar levels , producing various symptoms like abdominal cramps, bloating, diarrhoea, sweating, dizziness, nausea, weakness, and anxiety. This is managed by eating less amount of sugars and fats and spacing out the meals through the day, having four to five small meals compared to  2 to 3 large meals. Having a high protein diet and avoiding liquids during meals is also an option.

Bariatric Surgery - Know Problems Of It!

Bariatric surgery is a surgery performed on the stomach and is usually recommended for people who are obese. If you have a BMI value more than 40, then this surgery is a very good option. Along with those having an obesity problem, this surgery is also said to be ideal for those people who are suffering from type 2 diabetes and having a BMI value between 35 to 40.

There are many studies which show that there is a great improvement in people with type 2 diabetes after bariatric surgery. Even the cholesterol and blood pressure levels can also be controlled with the help of this surgery. Post-surgery, you will have to take fewer medicines or in some cases, you need not have to take medicine at all.

How does the doctor decide if you need bariatric surgery?
Basically, there are two things that will be considered by the doctor. The first one is the BMI value, which should be above 35. And the second parameter to consider is if you have tried any other methods to lose weight but did not succeed. Based on these and if you are ready to face the mental and physical challenges after the surgery, you will be advised to go through this surgery. You should make sure that you are doing regular exercise and also eat less.

Types of bariatric surgeries for type 2 diabetes

Gastric bypass: In this kind of surgery, the stomach is divided into two parts. One small part at the top is separated from the lower part of the stomach. Whatever you eat, will go into this small part of the stomach and that makes you feel full faster. Also, fewer nutrients and calories are absorbed into the body. After this kind of surgery, more than 80 percent of diabetes patients showed no signs of diabetes at all.
Gastric sleeve: In this surgery, a large portion of the stomach is removed and hence you will be able to eat less. This also reduces the amount of ghrelin, the hormone responsible for making you feel hungry, produced. This is successful in 60 percent of people with type 2 diabetes.
Adjustable gastric band: A small inflatable band is placed around the stomach. This will look like a small pouch at the place where the food goes in. This pouch will get full a lot quicker and hence you will not be able to eat too much.
Does it help?
Some surgeries show 80 percent success rate and some show 60 percent success rate, but that is in terms of diabetes levels. Due to less food, the body will not get the required minerals and vitamins, which will result in other health complications. Some surgeries are also irreversible. So, it is your doctor who understands the surgery and your health better and they will always suggest the best option for you.

Bariatric Surgery For Type 2 Diabetes - Does It Help?

Being overweight is becoming a common sight. However, opting for bariatric surgery is not the first option for everyone who is obese. Also to remember is that morbid obesity is not an isolated condition. It affects a person s overall physical and mental health in various ways, and therefore bariatric surgery becomes an option only as a last resort. 

Some defining criteria for this surgery would be:

A male who is at least 100 pounds overweight for his height or a female who is at least 80 pounds overweight for her height. This puts them at a body mass index (BMI) of more than 40.
If the BMI is in the range of 35 to 39 and if there are significant health issues like metabolic syndrome, then bariatric surgery can be done. For BMI less than 35, other conservative measures are usually tried before resorting to a surgical approach.
Most people with BMI in the range of 35 and above will have health issues like sleep apnoea, heart disease, lipid disorders, and metabolic syndrome.
Conservative measures to lose weight including diet changes and exercise have failed to produce any desired results.
The person, in addition to physical health, should also be emotionally strong to undergo the demands of bariatric surgery. There are changes involving almost all body systems including digestive, respiratory, cardiac, and musculoskeletal, and so the person needs to be prepared for a lifestyle change.
Strict lifestyle changes including diet and exercise are required, so the person needs to be counseled and convinced about these. A person who can see the long-term benefits will be willing to take the effort.
It is also essential that the person has a strong social support system. For immediate post-op care when skin flaps need to be managed, and for long-term emotional support to manage emotional issues, it works wonders if there is a strong social network. The results are usually better in such people.
A person s overall health would be screened to make sure the lab tests are well within acceptable limits before surgery. It would be unreasonable to get these numbers within limits, if they are way too beyond acceptable limits.
Not the least consideration, but bariatric surgery is an expensive affair. It requires not just surgical costs, but also post-op costs. The good thing, however, is that overall healthcare costs would come down, once the results are visible.
Identifying the right candidate for a bariatric surgery is very essential, as doing this extensive surgical approach on an unsuitable candidate would be a failure.

Bariatric Surgery - Who Is Eligible For The Same?

Is there a relation between weight loss surgery and type 2 diabetes? Yes, there is and a very promising one. Many diabetics may not know this but a key hole procedure called metabolic/ bariatric surgery can help resolve type 2 diabetes.

It s scientifically proven that these surgeries can normalize blood sugar levels and control diabetes in most patients. This means that you may not need any medicines post such a surgery. One long-term study which tracked 400 people with type 2 diabetes showed that six years after bariatric surgery, 62% diabetics showed normal blood sugar levels. Apart from this, they also showed better blood pressure, cholesterol and blood triglyceride levels that can cause heart disease.

Should you get a metabolic/bariatric surgery done? You are a fit candidate for bariatric surgery if your:

BMI is 27.5 or higher
And if are finding it difficult to maintain blood sugar with medicines & lifestyle changes.
Your doctor will give you a physical exam to check whether you are fit for a major surgery and if you are emotionally ready to commit to necessary lifestyle changes like eating healthy and exercising regularly.

Types of weight loss/diabetes surgery:

The most popular type of weight loss surgery is one in which the size of your stomach is reduced so that you feel full even after small meals. Other types of bariatric surgeries change the way your body absorbs calories and nutrients and vitamins. A few other types of bariatric surgeries do both.

Gastric Bypass: In this surgery, your surgeon makes a small stomach pouch by dividing the top of the stomach from the rest. This small pouch is connected to intestine so other part of stomach is bypassed. So, when you eat, food goes into this small pouch, which makes you feel full faster and also makes it possible for your body to absorb fewer calories. This is a very promising type of bariatric surgery for diabetics as up to 80% of people have normal blood sugar after it. And they also lose 60% to 80% of their extra weight on an average.
Gastric Sleeve: In this surgery, your surgeon will remove a major part of your stomach. When your stomach is small, you will feel full faster. It also reduces hunger pangs. This type of surgery is also very effective in reducing diabetes and losing weight.
Adjustable Gastric Band: In this surgery, your surgeon puts an inflatable band around the top of your stomach. This forms a small pouch which makes you feel full faster. The good point is that your stomach is not cut and your intestines are not shifted. There are thus lesser complications. It also helps in controlling diabetes. The con is that you lose less weight in this type of surgery.
Biliopancreatic Diversion: This is an uncommon surgery but most effective for diabetics. In this the doctor removes a large part of your stomach and also changes the way the food goes to your intestines. This helps in losing weight but also affects digestion long term.
As with any major operation, all bariatric surgeries come with potential risks of bleeding, infection, and leaks in the digestive system. It is necessary to change lifestyle to avoid weight regain.

Is There A Relation Between Weight Loss Surgery & Type 2 Diabetes?

Obesity can make life miserable. From unhealthy eating habits to unhealthy lifestyles and medical conditions, obesity can be an amalgamation of many factors. Obese people are a greater risk of suffering from many serious health complications like type-2 diabetes, mood swings, and depression, cardiac problems, high blood pressure and high cholesterol, to name a few. It does not stop there. More alarming is the fact that obese people are an increased risk of suffering from different types of cancer.

Bariatric surgery comes as a saviour for highly obese people (with a BMI over 40), who have tried every possible treatment under the sun to lose weight without any success. Bariatric surgery has helped many severely obese people attain a healthy weight. Bariatric surgery can be of three types;

Gastric bypass surgery (Roux-en-Y): This is one of the most common types of weight-loss surgery practised worldwide. The procedure involves rearranging (dividing) the stomach into a smaller upper pouch and a larger lower part. The smaller pouch is then connected to the small intestine. The food consumed will pass into the small intestine through the pouch. The idea is to rearrange the stomach in such a way that a person consumes a lesser quantity of food.
Gastric banding (Laparoscopic Adjustable Gastric Band): In this procedure, the surgeon creates a small pouch at the upper part of the stomach by placing a band (lap band or A-band) around it. The pouch, true to its name, is used to hold the food consumed. The purpose of placing a band around the stomach (upper part) is to reduce the intake of food.
Sleeve Gastrectomy (Gastric Sleeve surgery): In Sleeve Gastrectomy, surgeons remove a large portion of the stomach, leaving behind only a small sleeve-like pouch (hence the name). Like the other two surgeries, sleeve gastrectomy also aids in limiting the consumption of food.
Duodenal switch: The fourth type of bariatric surgery, Duodenal switch with biliopancreatic diversion, is not very commonly used. Bariatric surgery has several health benefits. In addition to the weight loss, it plays a pivotal role in lowering the incidences of Type-2 Diabetes, depression, anxiety, coronary artery problems, sleep apnea cardiovascular diseases.
Research also suggest that bariatric surgery has been instrumental in reducing the chances of cancer (especially colon and breast cancer) by as much as 60%. The correlation between weight loss and reduced cancer instances is still a debatable topic. Some researchers and oncologists believe that the weight loss (bariatric surgery) brings about a hormonal modification which prevents the growth of tumour cells. Another study links obesity with an increased inflammation. In many cases, inflammation acts as a catalyst, accelerating the growth of cancer cells. Research is still going on to understand this correlation (obesity and reduced cancer rates) better.

Bariatric surgery has its share of risks and demerits. Consult your physician and get yourself thoroughly examined before opting for the surgery.
