Losing weight is never easy. For many people, diets and exercise may not work in the long run. That’s when medical support becomes necessary. One of the most effective treatments available today is the gastric sleeve surgery.
This procedure has helped thousands of people manage their weight and health. It’s not a shortcut, but it is a medically proven method. Consulting an experienced bariatric surgeon is the first and most important step in the process. Let’s take a closer look at how this surgery works and what to expect before, during, and after the procedure.
Understanding How Gastric Sleeve Surgery Works
Gastric sleeve surgery is a type of weight-loss procedure. It reduces the size of your stomach to help you eat less and feel full faster. It also leads to reduction in the hunger hormone- Ghrelin and increase in other hormones like GLP 1, GIP and PYY
Here’s how it works:
- Around 75-80% of your stomach is removed.
- What remains is a narrow “sleeve” that looks like a banana.
- The surgery is done laparoscopically or robotically with small cuts.
- It does not involve rerouting the intestines like other surgeries.
This reduction limits food intake and lowers the hunger hormone (ghrelin), making you feel less hungry.
Who Should Consider This Procedure
This surgery is not for everyone. It’s recommended for those who meet the following:
- Have a Body Mass Index (BMI) of 35 Kg/m2 or higher.
- Have a BMI of 30+ with health issues like type 2 diabetes or high blood pressure.
- Are unable to lose weight through lifestyle changes alone.
- Are mentally and physically ready for long-term changes.
Doctors also assess your commitment to change, as this is a lifelong adjustment.
Preparing for the Surgery
Preparation is a key part of the success of gastric sleeve surgery. Here’s what patients usually go through:
- Initial Consultation: Your medical history and lifestyle will be reviewed.
- Tests and Screening: Blood tests, scans, enodscopy and sometimes sleep studies.
- Dietary Changes: You may be asked to follow a special pre-surgery diet for 1 to 2 weeks prior to surgery.
- Lifestyle Counseling: Nutritional and psychological support is often provided.
- Meeting an Expert: Consulting an experienced bariatric surgeon ensures you’re well-informed about every step.
Preparing properly increases the chances of a smooth recovery and better results.
What to Expect on the Day of Surgery
On the day of the surgery:
- You’ll be given anesthesia, so you’ll be asleep during the procedure.
- The surgery typically takes 1 to 2 hours.
- You’ll stay in the hospital for 1-2 days for observation.
Doctors monitor your health closely before sending you home.
Post-Surgery Recovery and Lifestyle Changes
Recovery from gastric sleeve surgery is relatively quick if instructions are followed.
After the surgery:
- First 15 days: Only liquids are allowed.
- Next 2 weeks: You move to pureed, then soft foods.
- Later on: You begin solid foods with a focus on nutrition.
- Activity: Gentle walking is encouraged early on.
Important habits to follow:
- Eat slowly and chew well.
- Avoid sugary and processed foods.
- Stay hydrated, but not during meals.
- Take prescribed vitamins and supplements daily.
- Attend follow-up visits to monitor progress.
It’s a journey that needs patience and consistency.
Benefits That Go Beyond Weight Loss
While weight loss is the goal, many patients see other improvements too:
- Better control of type 2 diabetes
- Lower blood pressure
- Improved sleep patterns
- Relief from joint pain
- Increased energy levels
- Boosted confidence and self-image
These benefits greatly improve daily life and overall health.
Risks and Considerations You Should Know
All surgeries carry some risk. Though gastric sleeve surgery is considered safe, patients should be aware of the following:
- Nausea or acid reflux in the initial weeks or even later sometimes
- Risk of leaks at the staple line (though rare)
- Risk of bleeding
- Possible vitamin or nutrient deficiencies
- Need for long-term follow-up
That’s why it’s essential to work with an experienced bariatric surgeon who can guide you throughout the process.
Long-Term Success Depends on You
The surgery is just one part of the solution. Success depends on how committed you are to lifestyle changes.
Here are some key steps to ensure long-term results:
- Join support groups or therapy sessions if needed.
- Track your food intake and exercise.
- Continue seeing your doctor regularly.
- Don’t skip supplements or medications.
- Set small goals to stay motivated.
The more effort you put in, the better your outcomes.
What Others Should Know Before Considering It
