Bariatric Surgery in Noida, India

Bariatric surgery, also known as weight loss surgery, encompasses various procedures designed to help individuals with obesity lose weight. These surgeries alter the digestive system to limit food intake or nutrient absorption. Bariatric surgery is often considered when diet and exercise alone have not been successful, and the patient has serious health issues related to obesity, such as diabetes, hypertension, or sleep apnea.

Signs and Symptoms Indicating the Need for Bariatric Surgery

• Severe Obesity: Typically defined as a body mass index (BMI) of 40 or higher.
• Obesity-Related Health Conditions: Such as type 2 diabetes, high blood pressure, heart disease, sleep apnea, or severe joint pain.
• Inability to Achieve a Healthy Weight Loss Sustained for a Period of Time: Despite dietary and lifestyle changes.

Why is Bariatric Surgery Performed?

Bariatric surgery is considered the most effective long-term treatment for class III obesity. The National Institutes of Health (NIH) states that individuals with class III obesity find it nearly impossible to maintain weight loss through diet and exercise alone. Once the body has adjusted to a higher weight as its “normal” state, it strives to return to that weight. Bariatric surgery modifies how the body processes food, making it easier for healthy dietary and lifestyle changes to lead to sustained weight loss and improved health.

Types of Bariatric Surgery

• Gastric Bypass (Roux-en-Y Gastric Bypass): This procedure involves creating a small stomach pouch and rerouting the small intestine to this pouch. It reduces the amount of food one can eat and decreases nutrient absorption.
• Sleeve Gastrectomy: In this surgery, a large portion of the stomach is removed, leaving a tube-like structure. This limits the amount of food one can consume and helps reduce hunger.
• Adjustable Gastric Band: A band is placed around the upper part of the stomach, creating a small pouch to hold food. The band can be adjusted to control food intake.
• Biliopancreatic Diversion with Duodenal Switch (BPD/DS): This complex surgery involves a sleeve gastrectomy followed by rerouting the intestines, which reduces both food intake and nutrient absorption.

What Conditions Can Bariatric Surgery Treat?

Obesity is linked to many chronic, potentially life-threatening diseases. Bariatric surgery and subsequent weight loss can significantly improve these conditions and risk factors, which include:

• High cholesterol: Excess lipids in the blood can lead to blockages in blood vessels, increasing the risk of stroke or heart attack.
• High blood pressure: Hypertension damages blood vessel walls, raising the risk of heart attack and stroke.
• High blood sugar: Hyperglycemia is associated with insulin resistance and can lead to diabetes and various complications.
• Type 2 diabetes: Excess fat can cause insulin resistance, significantly increasing the risk of developing type 2 diabetes.
• Heart disease: Obesity can impair cardiac function and lead to heart failure, plaque buildup in arteries, and increased risk of heart attack and stroke.
• Kidney disease: Obesity-related metabolic syndromes contribute to chronic kidney disease and kidney failure.
• Obstructive sleep apnea: This condition reduces oxygen flow to vital organs during sleep, endangering the heart.
• Osteoarthritis: Excess weight puts additional pressure on joints, leading to or worsening osteoarthritis.
• Non-alcoholic fatty liver disease (NAFLD): Excess fat in the liver can cause chronic inflammation and long-term liver damage.
• Cancer: Obesity is correlated with an increased risk of over a dozen types of cancer and higher cancer mortality rates.

Diagnosis and Evaluation

• Medical History and Physical Examination: Assessing the patient's weight history, health conditions, and previous attempts at weight loss.
• BMI Calculation: Determining the patient's body mass index to assess eligibility.
• Nutritional and Psychological Evaluation: Ensuring the patient is mentally and physically prepared for the surgery and its lifestyle changes.
• Laboratory Tests: Blood tests and other diagnostics to evaluate overall health and readiness for surgery.

Treatment

Preoperative Preparation

• Diet and Lifestyle Changes: Patients may need to lose some weight before surgery and adopt a healthy eating and exercise routine.
• Counseling and Support: Psychological counseling to prepare for the emotional aspects of weight loss and postoperative life.

Surgical Procedures

• Laparoscopic Surgery: Most bariatric surgeries are performed laparoscopically, involving small incisions and a camera to guide the surgery, resulting in faster recovery and fewer complications.
• Open Surgery: In some cases, an open surgery may be necessary, involving a larger incision in the abdomen.

Postoperative Care

• Dietary Changes: Gradual transition from liquids to solid foods, with a focus on nutrient-rich, low-calorie foods.
• Physical Activity: Incorporating regular exercise into daily routines.
• Regular Follow-Ups: Monitoring progress, managing any complications, and ensuring nutritional needs are met.

Common Myths About Bariatric Surgery

• Surgery is a Last Resort: Contrary to this belief, bariatric surgery is the most effective long-term treatment for class III obesity. Scientific studies have shown that diet and exercise—whether alone or combined with medications—are significantly less effective over the long term.
• Surgery is the “Easy Way Out”: Bariatric surgery should be seen as a tool that enables a healthy diet and lifestyle to result in sustained weight loss. Many patients have attempted these changes before without achieving long-term success. The surgery helps make these lifestyle changes more effective.

Risks of Bariatric Surgery

Consider the risks of the surgery itself and potential postoperative side effects:

Surgical Complications

• Bleeding
• Infection
• Blood clots
• Hernias
• Small bowel obstruction
• Anastomotic leaks

Surgery Side Effects

• Dumping syndrome: Symptoms like nausea, diarrhea, and abdominal cramping occur when food moves too quickly into the small intestine. These symptoms usually diminish over time, and dietary guidelines can help manage them.
• Malabsorption and malnutrition: Reduced nutrient absorption can lead to loose stools and nutritional deficiencies. Supplements will be prescribed to prevent this.
• Bile reflux: Malfunction of the pyloric valve can cause bile to backwash into the stomach, leading to gastritis and ulcers.
• Gallstones: Rapid weight loss can result in cholesterol buildup in the gallbladder, forming gallstones. Medication may be prescribed to prevent this.

Advantages of Bariatric Surgery

• Significant, sustained weight loss: The only proven long-term treatment for class III obesity.
• Reduced hunger hormones and improved metabolism: Surgery rewires the body’s metabolic programming, preventing weight regain.
• Cholesterol and blood sugar management: Often leads to diabetes remission and discontinuation of medications for metabolic syndromes.
• Longer, healthier life: Reduces risks of death from various causes by over 40%, in addition to alleviating obesity-related diseases and discomforts.
