What is Bariatric Surgery?

Bariatric surgery, also referred to as weight loss surgery, is a medical procedure designed to help individuals who are struggling with obesity and have not achieved long-term results through conventional weight loss methods. It is an effective weight loss operation that alters parts of the digestive system to limit food intake, reduce nutrient absorption, or both.

What Kind of Conditions can Bariatric Surgery Treat?

Bariatric surgery is more than just a weight loss operation. It plays a key role in managing and improving various health conditions that are linked to obesity. Here are the conditions that bariatric surgery can help treat or improve:

  • Type 2 Diabetes: Weight loss surgery helps lower blood sugar levels and improve insulin sensitivity. Many patients experience complete remission or better control of diabetes after surgery.
  • High Blood Pressure (Hypertension): A surgery to reduce fat can ease pressure on the arteries, improving blood flow and helping manage or reduce dependence on hypertension medications.
  • High Cholesterol (Hyperlipidaemia): With weight loss and lifestyle changes, cholesterol levels tend to improve significantly, reducing the risk of heart disease and stroke.
  • Heart Disease: Obesity-related heart conditions such as coronary artery disease, heart failure, and stroke risk factors can all improve with sustained weight loss after stomach surgery to reduce weight.
  • Obstructive Sleep Apnoea (OSA): Excess fat around the neck and chest can block airways during sleep. Weight loss operations often lead to dramatic improvement or complete resolution of OSA symptoms.
  • Non-Alcoholic Fatty Liver Disease (NAFLD) & NASH: Gastrointestinal sleeve and other procedures help reduce fat deposits in the liver, lowering inflammation and halting disease progression.
  • Osteoarthritis: Carrying extra weight puts strain on the joints, especially knees and hips. Losing weight can reduce pain and improve joint mobility.
  • Polycystic Ovary Syndrome (PCOS): For women, weight loss can improve hormonal balance, regularise periods, and boost fertility.
  • Chronic Kidney Disease (CKD): Obesity is a known risk factor for kidney disease. Bariatric surgery may lower this risk by improving blood pressure and blood sugar control.
  • Certain Types of Cancer: Obesity has been linked with increased risk of several cancers. While not a cancer treatment, weight loss can help reduce this risk.
  • Gastroesophageal Reflux Disease (GERD): Some procedures, especially gastric bypass, can reduce acid reflux symptoms, although not all surgeries are suitable for GERD patients.

Are you going through any of these symptoms?

Diagnosis Before Bariatric Surgery

Before undergoing a bariatric surgery or weight loss operation, a detailed evaluation is essential to ensure you are medically and mentally prepared for the procedure.

You will meet the following healthcare professionals:

  • Internist: They will take your complete medical history, perform a physical examination, and recommend blood tests to evaluate conditions like diabetes, high blood pressure, or sleep apnoea, which are often linked to obesity.
  • Dietician: A registered dietician will review your eating habits and guide you through the necessary lifestyle changes. You will receive a tailored bariatric diet plan, which you will be expected to follow before and after the surgery to support healthy weight loss.
  • Psychiatrist or Psychologist: Mental wellbeing plays an important part of your journey. A psychological evaluation ensures you are emotionally ready to cope with the changes after the surgery to lose weight and can maintain the required long-term adjustments.
  • Bariatric Surgeon: The surgeon will assess your eligibility and may advise a short-term preoperative weight loss through diet and exercise to lower blood sugar levels and reduce surgical risks.

Tests Done Before Bariatric Surgery

Several diagnostic tests are carried out to ensure your safety and to plan the most appropriate weight loss surgery, such as a gastric sleeve surgery or other common procedures. These include:

  • Complete Blood Tests

To check for anaemia, infection, blood sugar levels, and nutritional deficiencies.

  • Abdominal Ultrasound

To examine the liver, gallbladder, pancreas, and kidneys, and detect any potential issues like gallstones or fatty liver.

  • Electrocardiogram (ECG/EKG)

This test helps evaluate your heart’s condition, especially if you have a history of high blood pressure, diabetes, heart disease, or impaired lung function.

  • Chest X-ray

To assess your lungs and overall respiratory health before anaesthesia.

  • Sleep Study (if needed)

For individuals suspected of sleep apnoea, this test helps evaluate breathing patterns during sleep.

  • Upper Endoscopy or Barium Swallow Test (if advised)

These help in identifying any abnormalities in the stomach or oesophagus that may affect the surgery plan.

Types of Bariatric Surgery

Bariatric surgery, also called weight loss surgery, includes a variety of procedures designed to help individuals with obesity lose weight and reduce their risk of serious health conditions. Here are the most common bariatric surgery types available:

1. Gastric Sleeve Surgery (Sleeve Gastrectomy)

One of the most common bariatric surgeries performed today, this procedure involves removing nearly 80% of the stomach. The remaining portion is shaped like a tube or “sleeve”, limiting how much food you can eat and reducing hunger by lowering the production of the hunger hormone ghrelin.

Benefits of this weight loss operation:

  • Helps you feel full sooner, reducing overall food intake
  • Improves blood sugar control and insulin sensitivity
  • Supports long-term weight loss with fewer complications
  • Often considered the most common bariatric surgery globally

2. Gastric Bypass (Roux-en-Y Gastric Bypass)

This advanced weight loss procedure combines stomach reduction with an intestinal bypass. Surgeons create a small stomach pouch and reroute part of the small intestine to it. As a result, both food intake and calorie absorption are reduced.

Key benefits of this bariatric surgery:

  • Significant and sustained weight loss
  • Improves or resolves type 2 diabetes, high blood pressure, and other metabolic conditions
  • Reduces absorption of calories and nutrients, which contributes to weight loss

3. Mini Gastric Bypass

A simpler version of the traditional gastric bypass, this procedure reduces both the size of the stomach and the length of the digestive tract involved in nutrient absorption. It’s a less invasive alternative with excellent outcomes for many patients.

Benefits of this procedure:

  • Requires shorter operation time
  • Promotes effective weight loss
  • Has a lower risk of complications compared to the standard bypass

4. Biliopancreatic Diversion with Duodenal Switch (BPD/DS)

This complex procedure is generally reserved for patients with a very high BMI or severe metabolic disease. It involves a gastric sleeve followed by a bypass of a large portion of the small intestine.

Benefits of this operation:

  • One of the most effective options for long-term weight loss
  • Greatly improves conditions like diabetes and high cholesterol
  • Strong appetite control due to hormone regulation

 

Surgery Type What It Involves Key Benefits Who It’s For
Gastric Sleeve (Sleeve Gastrectomy) Removes about 80% of the stomach, leaving a sleeve-shaped pouch – Feel full faster- Better blood sugar control- Long-term weight loss with fewer complications Most common choice worldwide
Gastric Bypass (Roux-en-Y) Small stomach pouch created, intestine rerouted to reduce calorie absorption – Significant, lasting weight loss- Helps diabetes & blood pressure- Cuts calorie & nutrient absorption For those needing stronger results
Mini Gastric Bypass Smaller stomach and shorter digestive tract than traditional bypass – Shorter surgery time- Effective weight loss- Lower complication risk Less invasive option with good results
Biliopancreatic Diversion with Duodenal Switch (BPD/DS) Sleeve gastrectomy plus bypass of a large part of small intestine – Very effective long-term weight loss- Improves diabetes & cholesterol- Strong appetite control For very high BMI or severe metabolic issues

Preparation for Bariatric Surgery

Preparing for bariatric surgery is an important step to ensure your weight loss operation is safe and effective. Here’s what to expect before your stomach reduction operation:

  • Medical evaluation: You will undergo a full medical assessment to determine if you are fit for surgery. This includes blood tests, imaging studies, and sometimes an endoscopy. If you have any pre-existing conditions like diabetes, high blood pressure, or sleep apnoea, they will need to be managed before your surgery to lose weight.
  • Nutritional counselling: A tailored bariatric diet will be provided to help you prepare your body for surgery. You may be asked to lose a small amount of weight beforehand to reduce fat around the stomach and liver, making the stomach surgery to reduce weight safer and more efficient.
  • Lifestyle adjustments: If you smoke, consume alcohol excessively, or use recreational drugs, you will need to quit well in advance of surgery. These habits can increase the risk of complications and delay recovery.
  • Mental health support: Emotional readiness is just as important as physical health. You may be referred to a psychologist or counsellor to assess your mental preparedness and ensure you have a strong support system in place.
  • Pre-surgery instructions: In the weeks leading up to your gastrointestinal sleeve or gastric bypass, you will receive clear instructions regarding medications, fasting, and hydration. Following these guidelines will help minimise surgical risks.

Post Operative Care

After undergoing bariatric surgery, proper postoperative care is key to ensuring long-term success and avoiding complications. Here is what to expect in the months following your surgery to reduce fat:

  • Regular follow-up appointments: You will have scheduled check-ups with your surgeon and care team to track weight loss, evaluate healing, and identify any nutritional deficiencies. These visits are most frequent during the first year after your surgery.
  • Nutritional support and supplements: Because your body will absorb fewer nutrients after procedures like gastric sleeve surgery or other stomach reduction operations, you will need lifelong vitamin and mineral supplements. Our nutritionists will also help you follow a proper bariatric diet suited to your body’s new needs.
  • Monitoring for side effects: We closely watch for any signs of dumping syndrome, nausea, fatigue, or vitamin deficiencies. If issues arise, your treatment plan will be adjusted to help manage symptoms and keep you healthy.
  • Physical activity guidance: Light physical activity is usually encouraged within a few weeks of surgery. Over time, we will help you incorporate safe, regular exercise to support your progress and maximise the benefits of bariatric surgery.
  • Long-term care planning: After a year, if you have lost a significant amount of weight, you may consider body contouring procedures to remove loose or excess skin.

Risk and Complications of Bariatric Surgery

Like any major weight loss procedure, bariatric surgery carries certain risks. Here are the possible risks and complications you should be aware of:

Short-term risks (immediately after surgery)

  • Bleeding: Excessive bleeding during or after surgery.
  • Infection: Risk of infection at the surgical site.
  • Reactions to anaesthesia: Includes nausea or allergic responses.
  • Blood clots: Especially in the legs (deep vein thrombosis).
  • Breathing problems: Difficulty breathing post-anaesthesia.
  • Leaks in the gastrointestinal tract: Can occur at the staple line in surgeries like gastric sleeve surgery.

Long-term risks (weeks to years after surgery)

  • Dumping syndrome: A common condition after weight loss operations, causing nausea, diarrhoea, dizziness, or vomiting after eating.
  • Gallstones: Often form due to rapid weight loss.
  • Hernias: Can develop at or near the incision site.
  • Low blood sugar (hypoglycaemia): May occur if your blood sugar drops too quickly.
  • Malnutrition: Especially if the bariatric diet is not followed or supplements are not taken.
  • Ulcers: May develop in the stomach or small intestine.
  • Vomiting: Especially after eating too quickly or too much.
  • Acid reflux: Common after certain types of bariatric surgery.
  • Bowel obstruction: Blockages in the intestines can occur.
  • The need for revision surgery: A second operation to reduce fat may be needed if complications arise or weight regain occurs.

Benefits of Bariatric Surgery

Bariatric surgery is a clinically proven, long-term solution for people struggling with obesity when diet, exercise, and non-surgical weight loss procedures have not been effective. Key benefits of bariatric surgery:

  • Long-term, sustainable weight loss

Bariatric surgery helps individuals lose a large amount of excess weight and maintain it long term, especially in cases of class III obesity.

  • Improved metabolism and reduced hunger

Procedures like the gastrointestinal sleeve can alter gut hormones, leading to reduced appetite and better metabolic control.

  • Better control of blood sugar and cholesterol

Many patients experience remission of type 2 diabetes and reduced dependence on medication after their weight loss operation.

  • Lower risk of obesity-related conditions

These surgeries reduce the risk of serious health problems such as heart disease, high blood pressure, stroke, sleep apnoea, and joint pain.

  • Enhanced quality of life

Weight loss can lead to improved mobility, better mental health, increased energy levels, and greater self-confidence.

  • Potential increase in life expectancy

Research shows that people who undergo bariatric surgery may live longer, with up to a 40% reduction in the risk of death from obesity-related causes.

  • Support for healthy lifestyle changes

After bariatric surgery, patients follow a structured bariatric diet and receive long-term guidance, helping them adopt and maintain a healthier lifestyle.

  • Minimally invasive procedures with quicker recovery

At Pristyn Care, we offer laparoscopic and laser-assisted options for surgery loss weight, which reduce hospital stay and speed up healing.

Frequently Asked Questions on Bariatric Surgery

Why do people usually need bariatric surgery?

It is recommended when someone has severe obesity and hasn’t been able to lose enough weight through diet or exercise alone.

Who can get bariatric surgery?

You may be eligible if your BMI is 35 or higher with related health issues or over 40 without them, and other weight loss methods haven’t worked.

Is it true that weight loss surgery is the easy way out?

No, that is a myth. Bariatric surgery is a tool, not a shortcut. It still requires major changes to your lifestyle and eating habits after the procedure.

How is bariatric surgery actually done?

At Pristyn Care, we use minimally invasive methods like gastric sleeve surgery or other stomach reduction operations, which involve making the stomach smaller to reduce food intake.

How much weight can someone expect to lose after the surgery?

Most people lose between 50 to 70% of their excess weight within one to two years after the operation.

What’s the usual recovery time after bariatric surgery?

Recovery generally takes about 2 to 4 weeks, depending on the type of weight loss procedure and how well you follow the post-op guidelines.

How successful is bariatric surgery in the long run?

When paired with a proper bariatric diet and medical follow-up, the results are long-lasting and highly effective for most patients.

What if someone doesn’t lose weight after the surgery?

Weight regain can happen if the recommended lifestyle changes are not followed, but support from doctors and dieticians helps keep patients on track.

How much does bariatric surgery cost in India?

The cost for a weight loss operation in India usually ranges from ₹2.8 lakh to ₹6 lakh, depending on the type of surgery.

Will insurance cover the cost of bariatric surgery?

Yes, many insurers do cover bariatric surgery, but it usually depends on your BMI. If your BMI is over 40, you are more likely to be eligible. For those with a BMI between 35 and 40, coverage might still be possible, but there are certain terms and conditions involved. If your BMI is below 35, insurance won’t cover the surgery at all.
