Will metabolic surgery help my health issues (BMI 48.2, A1c 8.9 %)?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I need advice about metabolic surgery options. I have struggled with my weight for 22 years. I am 41 years old, weigh 297 lbs, and have a BMI of 48.2. Recently, I was diagnosed with sleep apnea (AHI 37), and my blood pressure stays around 158/92 mmHg despite taking 40 mg of Lisinopril daily. My A1c jumped to 8.9 % last month, and my doctor put me on metformin, but I am experiencing severe diarrhea from it. My knees hurt so much that I had to quit my job as a delivery driver.

I have tried several weight loss methods, including Weight Watchers, keto, intermittent fasting, and even Phentermine, but nothing has worked long-term. My cousin had gastric sleeve surgery two years ago and lost 118 pounds, but she now has vitamin deficiencies.

Would metabolic surgery help with my health problems, or would it only address the weight? Is the sleeve better than bypass? My insurance might cover the surgery, but I am concerned about the complications I have read about online. Please help.

Thank you in advance.

Hi,

Welcome to icliniq.com.

I read your query and can understand your concern.

I have reviewed your case and understand your concerns. Given that you are 41 years old with a BMI (Body Mass Index) of 48, which falls under class 3 obesity (most severe form of obesity), and have uncontrolled diabetes (high blood sugar levels) and hypertension (high blood pressure), you are a strong candidate for bariatric or metabolic surgery (weight loss surgery).

In such cases, the risks of not opting for surgery, including the continued progression of diabetes (high blood sugar levels), cardiovascular (heart) disease, and kidney damage, can outweigh the risks of the surgery itself, especially if medications and lifestyle changes have not been effective.

Metabolic surgery (a procedure to help with weight loss by altering the digestive system) can significantly improve blood sugar and hypertension, with around 60 to 70 % of patients achieving remission of diabetes and hypertension (high blood pressure), depending on the type of procedure.

Types of bariatric surgeries:

Sleeve gastrectomy (weight-loss surgery where about 75-80% of the stomach is removed, leaving a small, tube-shaped stomach):

  1. Up to 80 % of the stomach is removed.
  2. Highly effective for weight loss and improving diabetes.

Roux-en-Y gastric bypass (RYGB): A weight-loss surgery where a small pouch is created at the top of the stomach, which is then connected directly to the small intestine, bypassing part of the stomach and duodenum.

  1. Creates a small stomach pouch and reroutes part of the small intestine.
  2. Most effective for type 2 diabetes remission.

Mini gastric bypass (one anastomosis bypass): A type of weight-loss surgery that involves creating a small stomach pouch and rerouting a portion of the small intestine to connect to it.

  1. Shorter surgery with fewer complications.
  2. Effective for weight loss and diabetes improvement.

Adjustable gastric banding: A weight-loss surgery where a band is placed around the upper part of the stomach to create a small pouch

  1. High long-term complication rates and need for reoperations.

Biliopancreatic diversion with duodenal switch (BPD-DS): A weight-loss surgery that combines two procedures. First, a large portion of the stomach is removed (sleeve gastrectomy), leaving a small pouch.

  1. Highest weight loss and diabetes remission rates.
  2. Higher risk of malnutrition, requiring lifelong vitamin and protein supplementation.

Key differences between sleeve gastrectomy and Roux-en-Y gastric bypass:

Sleeve gastrectomy:

  1. 75 to 80 % of the stomach is removed.
  2. No intestinal bypass; only restrictive.
  3. Reduces stomach volume and decreases the hunger hormone (ghrelin).
  4. Minimal malabsorption, lower risk of deficiencies.
  5. Weight loss: 60 to 70 %.

Roux-en-Y gastric bypass (RYGB):

  1. A small stomach pouch is created and connected directly to the jejunum.
  2. Bypasses part of the stomach and duodenum.
  3. Both restrictive and malabsorptive alterations affect gut hormones.
  4. Significant malabsorption with a higher risk of deficiencies in iron, B12, and calcium.
  5. Weight loss: 65 to 80 %.

Complications:

  1. Bleeding, infections, and anastomosis (surgical connection made between two structures) leakage.

Recovery period:

  1. Hospital stay: one to three days.
  2. Full activity: four to six weeks.
  3. Gradual reintroduction of food, starting with liquids, soft foods, and then regular meals.

Most patients lose 60 to 80 percent of their excess weight and maintain long-term improvements in blood sugar and blood pressure. Regular follow-up, nutritional counseling, and possibly lifelong vitamin supplementation are required.

For more personalized advice, consulting with a bariatric surgeon will help you choose the best option for your needs.

I hope this helps.
