Is metabolic surgery helpful at 38 with a BMI of 42?

Question

Hello doctor,

I am a 38-year-old woman with a BMI of 42, and I have been struggling with obesity and related health issues like sleep apnea and PCOS for years. I have tried every diet and medication, and I am still not seeing meaningful progress. My primary care doctor is now suggesting metabolic surgery, like a gastric bypass or sleeve gastrectomy. I am very nervous about undergoing surgery, especially the risks and how much it will change my life long-term. Will I have to be on supplements forever? How much weight can I realistically lose and keep off? Is it worth it?

Please help.

Hello,

Welcome to icliniq.com.

I understand your concern.

As you mentioned, you are 38 years old with a BMI (body mass index) of 42, which falls into class three obesity, with uncontrolled diabetes and hypertension, so you are a strong candidate for bariatric or metabolic surgery.

In such cases, the risk of not opting for surgery, continued progression of diabetes, cardiovascular disease, and kidney damage, can outweigh the risks of surgery itself, especially if medications and lifestyle changes have not been effective.

Metabolic surgery can really help to improve both blood sugar and hypertension, depending on the type of surgical procedure. With around 60 to 70 percent inducing remission for diabetes.

There are different types of bariatric surgeries:

Sleeve gastrectomy (up to 80 percent of the stomach is removed) is very effective for weight loss, diabetes improvement.
Roux-en-y-gastric bypass (RYGB) creates a small stomach pouch and reroutes the small intestine to bypass part of the stomach and duodenum. Most effective for type 2 diabetes remission.
Mini gastric bypass (one anastomosis bypass) is a shorter surgery, has fewer complications, and is effective for weight loss and diabetes.
Adjustable gastric banding has a high rate of long-term complications and reoperations.
Biliopancreatic diversion with duodenal switch (BPD-DS) has the highest weight loss and diabetes remission rates, and a high risk of malnutrition. It requires lifelong strict vitamin and protein supplementation.

The main difference between sleeve gastrectomy and Roux-en-Y gastric bypass is :

Sleeve gastrectomy:

About 75 to 80 percent of the stomach is removed, leaving a narrow gastric "sleeve."
No intestinal bypass; only restrictive.
Reduces stomach volume and decreases ghrelin (hunger hormone).
Malabsorption, lower risk of deficiencies.
Weight loss is around 60 to 70 percent.

Roux-en-y gastric bypass (RYGB):

A small stomach pouch is created and connected directly to the jejunum.
Bypasses the duodenum and part of the jejunum.
Both restrictive and malabsorptive.
Reduces intake and nutrient absorption, also alters gut hormones.
Significant malabsorption; higher risk of deficiencies in iron, vitamin B12, and calcium.
Weight loss is around 65 to 80 percent, slightly more than sleeve gastrectomy.

Complications include:

Bleeding, infections, and anastomosis leakage.

Recovery period:

Usually, hospital stay is one to three days.
Can do full activity within four to six weeks.
You will follow a structured plan starting with liquids, then soft foods, then regular meals over a few weeks.

Most patients lose 60 to 80 percent of excess weight and maintain long-term improvements in blood sugar and pressure.

You will need to commit to regular follow-up, nutritional counseling, and possibly vitamin supplements for life.

I hope this has helped you.
