Bariatric Surgery

Last Update Date: 9/2/2025 2:10:29 AM

What is Bariatric Surgery?

Bariatric surgery changes the stomach’s capacity and/or intestinal absorption to support long term weight loss. You take in fewer calories, feel full sooner, and experience hormonal shifts that reduce hunger. It works best alongside nutrition counseling, activity planning, and regular medical follow up.

Metabolic effects: Improved insulin sensitivity and reduced hunger.

Comorbidity improvement: Type 2 diabetes, sleep apnea, hypertension, and fatty liver often improve.

Quality of life: Mobility, energy, and confidence commonly increase.

Bariatric Surgery

Types of Bariatric Surgery for Obesity

We choose the type of surgery based on your health, eating habits, reflux, diabetes, and safety needs. Our goal is to find the option that works best and is safest for you.

Types of Bariatric Surgery Include Gastric Bypass and More 

Sleeve gastrectomy: Removes part of the stomach; reduces volume and ghrelin (hunger hormone).

Gastric bypass (Roux en-Y): Creates a small stomach pouch and reroutes the intestine; reduces intake and absorption.

Other options Include One Anastomosis gastric bypass and revisional procedures in selected patients.

H3: Best Bariatric Surgery for Morbidly Obese Patients

There is no one size fits all procedure. Your BMI, reflux, diabetes, medications, and past surgeries all play a role in the decision. Your care team will help you choose the safest and most effective option for you. 

Bariatric Surgery vs Non Surgical Treatment for Obesity

For people with severe obesity or obesity and diabetes, surgery often leads to more lasting weight loss than lifestyle changes alone. It can also help improve or even reverse diabetes and other health problems. Support with healthy habits is still important before and after surgery.

Bariatric Surgery Versus Medical Therapy for Obese Diabetic Patients

Surgery usually helps people reach better blood sugar levels, need fewer medications, and lose more weight than medical treatment alone. Your doctors will work together to adjust your care and medications after surgery.

Bariatric Surgery for Obesity and Metabolic Conditions in Adults

Type 2 diabetes: Improved control or remission in many patients

Blood pressure and lipids: Frequently improve

Sleep apnea: Often reduced or resolved

Joint pain and mobility: Commonly improved

Fertility and PCOS: May benefit from weight loss 

Surgery is not just about size, it's about changing how your body processes food, regulates hunger and supports lasting change. Make sure you understand how the chosen procedure works, its risks, benefits and the commitment required afterwards.

Risks and Safety

Potential Health Risks and Side Effects of Bariatric Surgery

Every surgery has risks, such as bleeding, infection, blood clots, leaks, reflux, gallstones, or narrowing. Over time, some people may have vitamin shortages or gain weight back. Careful planning, skilled surgeons, and regular follow up visits help keep you safe and support your recovery.

Nutritional Deficiencies After Bariatric Surgery: What to Know

You will need to take vitamins and minerals, get regular blood tests, and meet with a nutritionist to avoid shortages like iron, B12, vitamin D, or calcium. Dietitians will help you move from liquid foods to solids and set goals for portions and protein.

Frequently Asked Questions for Bariatric Surgery

How can bariatric surgery overcome obesity?

Bariatric surgery changes the digestive system to help you lose substantial weight and keep it off. It reduces stomach size and affects gut hormones, lowering hunger and improving fullness and blood sugar control. With nutrition, activity, and follow up care, many patients see remission or improvement of diabetes, sleep apnea, high blood pressure, and fatty liver disease.

Which statement about bariatric surgery in obese adults is false?

False: “Bariatric surgery is a quick fix.” Truth: Surgery is a powerful medical tool, not a shortcut. Success requires lifelong healthy eating, activity, vitamins, and regular follow up. Most patients achieve significant weight loss and health improvements when they follow the program their care team recommends.

Can you get bariatric surgery without being obese?

No. Bariatric surgery is intended for patients who meet medical criteria for obesity. Typical guidelines include BMI ≥40, or BMI ≥35 with obesity related conditions (such as type 2 diabetes or sleep apnea). In select cases, BMI 30–34.9 with uncontrolled metabolic disease may qualify after specialist evaluation.

Is bariatric surgery the answer to obesity?

It’s the most effective treatment for severe obesity and for obesity with metabolic disease when lifestyle and medications aren’t enough. Surgery supports large, durable weight loss and improves many conditions. It’s not the only “answer” it works best within a comprehensive program that includes nutrition, activity, behavioral support, and ongoing medical care.

Is bariatric surgery good for those who are slightly obese?

Generally, no. For people who are overweight or have mild (class 1) obesity without major health issues, non surgical treatments are recommended first: personalized nutrition, physical activity, behavioral therapy, and, when appropriate, anti obesity medications. Surgery may be considered in select cases of class 1 obesity with significant metabolic disease after specialist review.

Are you obese and diabetic? Consider bariatric surgery.

If you live with obesity and type 2 diabetes, bariatric surgery can improve blood sugar control, reduce medications, and, in many cases, lead to diabetes remission. Outcomes are best with a coordinated team (surgeon, endocrinologist, dietitian) and long-term follow up. Ask about your eligibility and the procedure that best fits your health profile.

Can I get bariatric surgery if I’m not obese?

No. You must meet medical criteria for obesity based on BMI and health conditions. Your care team can guide you to effective non surgical options if you do not qualify.
