What Is Gastroplasty? Pros, Cons and Recovery Explained

If you're looking for a safe, effective way to lose weight without undergoing a major surgery, you may have come across the term gastroplasty. But what is gastroplasty, and more importantly, is it the right option for you?

When talking about gastroplasty, we refer to Endoscopic Sleeve Gastroplasty (ESG). It is a non-surgical solution with real, sustainable results. We will go through what ESG is and the key pros and cons to consider before you make your decision.

What is Gastroplasty?

Gastroplasty is a general term used to describe procedures that reduce the size of the stomach to help limit food intake and promote weight loss. As we've already mentioned, one of the most innovative forms is ESG.

ESG is a minimally invasive, non-surgical procedure performed through the mouth using an endoscope. No incisions, no hospital stay, and significantly less risk than traditional weight loss surgery.

5 Pros of Endoscopic Sleeve Gastroplasty

1. Minimally Invasive and potentially reversible

One of ESG's biggest advantages is that it's done without any incisions or cuts. The procedure is performed entirely through the mouth using an endoscope - a flexible tube with a camera.

• Having a minimally invasive procedure means:
• No visible scars (aesthetic and psychological benefit)
• No removal of stomach tissue
• Reduced risk of surgical complications
• Less post-op pain and faster healing

ESG is a great option if you're anxious about going "under the knife" or want to avoid the risks that come with more invasive procedures.

ESG is also potentially reversible. Unlike sleeve gastrectomy, where part of your stomach is permanently removed, ESG reshapes the stomach with internal sutures that can be undone or revised in the future if needed.

2. Short Recovery Time

Because there's no cutting or stapling of the stomach, you can go home the same day. Most people return to normal activities within 2 to 4 days.

Compared to the 2- to 6-week recovery period that follows surgical options, ESG gives you a chance to get back to life (and work) much faster and with fewer disruptions.

3. Impressive Weight Loss Results

Even though ESG is less invasive than traditional bariatric surgery, it still delivers impressive weight loss results. On average, patients lose up to 28% of their total body weight.

Some studies show comparable results to more invasive procedures, especially when patients are consistent with lifestyle change, get the right post-procedure support, and follow their nutritionist's instructions.

4. Improvement in Obesity-Related Medical Conditions

Beyond its direct impact on weight loss, ESG plays an important role in improving or resolving numerous health conditions that you might face and are associated with obesity:

• Heart disease
• High blood pressure (hypertension)
• Severe sleep apnea
• Type 2 diabetes
• Gastroesophageal reflux disease (GERD)
• Joint pain

5. Lower Risk of Nutritional Deficiencies

Since  ESG doesn't involve bypassing the intestines or removing part of the stomach, your body continues to absorb nutrients the same way it has before the procedure. This reduces the risk of:

• Vitamin and mineral deficiencies
• Malabsorption issues
• Lifelong supplement dependency

You still need to be mindful of the portion size when eating, but there is no need to worry about complex supplementation routines.

5 Challenges of Gastroplasty

Despite its many advantages, ESG still presents several challenges that you should be aware of and consider before making the decision.

1. Limited Insurance Coverage

Can I afford it? is one of the most common concerns patients have when it comes to the procedure. Not all insurance companies cover ESG, because they still perceive it as a relatively new weight loss procedure.

Check with your insurance carrier and explore payment plans before deciding on the procedure.

2. Strong Commitment to Lifestyle Changes

What your doctor will constantly repeat and what you will hear most often from people who have had ESG is that the surgery is just the beginning.

• For long-term success, you'll need to:
• Follow a structured eating plan and fluid management
• Incorporate physical activity
• Attend regular follow-up visits

Weight loss is a team effort. Make sure you find a team where you will feel fully supported, preferably in as many areas as possible, among your friends, family, and of course, healthcare professionals.

3. Less Dramatic Weight Loss Compared to Surgery

While ESG results are impressive, they're typically a bit more moderate than those from sleeve gastrectomy or gastric bypass.

With every weight loss, there is always a risk of weight regain, but it is completely in your hands and under your control. You can avoid it by following the recommendations we listed in the previous section.

4. Short-Term Side Effects Are Common

While many have positive outcomes, the initial recovery and ongoing physical adjustments can be challenging. Patients frequently discuss the pain and discomfort, particularly from gas, and the big changes in their dietary habits.

These are some of the most frequent side effects:

• Nausea
• Vomiting
• Cramping
• Fatigue
• Bloating

They are usually manageable with medications and hydration, but in rare cases, complications like bleeding or infection can occur—especially if post-op guidelines aren't followed.

5. Still Considered "New" by Medical Standards

Although ESG has been performed successfully for over a decade and has FDA authorization for the tools used, some still view it as experimental.

Why?

• Long-term data is still emerging.
• It's not as widely practiced as surgery
• Not all bariatric centers offer ESG yet

That said, newer doesn't mean unproven. Recent studies show excellent results in both safety and effectiveness.

Is ESG the Right Kind of Gastroplasty for You?

If you're considering a procedure and wondering what is gastroplasty  and how ESG fits into your options, remember that this is your personal decision. ESG gives you a powerful blend of non-surgical convenience and real weight loss, without the downtime or permanent changes of surgery.

But like any medical procedure, it has its trade-offs. And the best thing you can do, when considering if ESG is right for you, is book a personalized consultation with a bariatric specialist who will go through your medical history, goals, and preferences.

FAQ

How long does it take to recover after ESG, and when can I return to work?

You can expect to go home the same day and return to normal activities within 2 to 4 days. This is much faster than surgical options, which often require from 2 to 6 weeks of recovery.

‍

How much weight can I realistically expect to lose with ESG?

On average, patients lose up to 28% of their total body weight within the first year. Results depend on your commitment to healthy eating, regular exercise, and follow-up care.

‍

What lifestyle changes will I need to make after ESG to get the best results?

You’ll need to strictly follow a structured eating plan, stay hydrated, avoid overeating, and include regular physical activity. Beside that, ongoing support from healthcare providers, nutritionists, and a strong personal support system is also very important to have.
