Is gastric bypass safe to treat obesity with comorbidities?

Question

Hello doctor,

My health has spiraled out of control due to my weight. I currently weigh 341 pounds at 5 feet 7 inches, with a BMI of 53.4, and I am struggling with multiple obesity-related health issues. My diabetes is completely unmanaged, with an A1c of 10.3, despite taking Metformin 2000 mg daily, Glipizide 10 mg twice daily, and weekly Ozempic injections. My blood pressure averages 178/98 even while on three medications. I have severe sleep apnea that requires a CPAP at the highest setting, yet I still wake up gasping for air. My joints are rapidly deteriorating. I had a right knee replacement last year, my left knee is now bone-on-bone according to X-rays, and I am experiencing such severe lower back pain that I can barely walk 50 feet without stopping. Most concerning is a recent cardiology evaluation that revealed moderate heart failure, with an ejection fraction of 38 percent and an enlarged left ventricle. Over the past 20 years, I have tried every diet imaginable, losing some weight only to regain even more. A dietitian had me track my intake for three months, but even consuming just 1500 calories a day led to minimal weight loss. I am constantly exhausted, unable to play with my grandchildren, and was recently forced to retire early from my teaching job because I could no longer stand long enough to lead a class. My primary care doctor has now referred me to a bariatric surgeon, who recommends a gastric bypass. I am desperate enough to consider it, but terrified of the potential complications. How risky is this surgery, given my heart condition? Can it realistically improve my diabetes and heart failure? And how much weight could I expect to lose?

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern.

It is truly admirable that you are so proactive about your health. As you rightly pointed out, obesity presents significant systemic health risks, including cardiovascular problems, endocrine disorders such as uncontrolled diabetes, and joint issues. Specifically, it affects your cardiovascular health by, among other things, placing undue strain on your heart and contributing to uncontrolled hypertension, atherosclerotic heart disease, obesity hypoventilation syndrome, pulmonary hypertension, and cor pulmonale.

Given the wide range of health concerns associated with obesity, addressing it is of paramount importance. Bariatric surgeries have become remarkably safe, and with the advent of advanced techniques, they are highly successful procedures.

Effective management of obesity leads to significant improvements in overall health. Weight loss can reduce insulin resistance, resulting in better blood sugar control. Similarly, blood pressure often improves, and blood lipid levels tend to fall within a healthier range. Furthermore, it lowers the risk of atherosclerotic heart disease progression and ischemia, consequently decreasing the likelihood of stroke, heart failure, and sudden cardiac death.

The risks associated with bariatric surgery vary depending on the specific type of surgery and the patient's overall health status. These risks can include infection, bleeding, leakages, perioperative cardiac events, arrhythmias, and potential long-term complications such as bowel obstruction, electrolyte imbalances, acidity and acid reflux, incisional hernias, and hypoglycemia. Considering your moderate left ventricular systolic dysfunction, the risk is slightly elevated. However, the overall risk-versus-benefit profile generally favors undergoing bariatric surgery if your physician recommends it after a comprehensive evaluation of your overall health and fitness.

The degree of weight loss achieved can be substantial, although individual responses may vary. When bariatric surgery is combined with a tailored diet and medication, all under the supervision of an experienced healthcare professional, the outcomes are typically very positive.

I hope this helps.
