What are the weight loss options for a 43-year-old?

Question

Hi doctor,

I am a 43-year-old man who has struggled with obesity most of my adult life. My BMI is 36, and despite multiple attempts at dieting and exercising, I lose some weight but gain it back. I am considering medical weight-loss options like GLP-1 agonists or even bariatric surgery, but I am not sure which approach is more sustainable. How do doctors determine the right treatment plan for someone like me, and what health checks should I undergo before starting?

Thanks.

Hi,

Welcome to icliniq.com.

I can understand your concern.

For someone with a BMI (body mass index) of 36 who has struggled with long-term obesity despite diet and exercise, it is understandable to explore medical and surgical weight loss options. Doctors usually take a personalized approach when deciding the best treatment plan. The first step is a comprehensive medical evaluation to identify underlying causes or complications of obesity, such as hypothyroidism, sleep apnea, type 2 diabetes, hypertension, or metabolic syndrome.

This typically involves blood tests for fasting glucose, HbA1c, lipid profile, thyroid function, liver and kidney function, and possibly hormonal assessments if indicated. If you have obesity related conditions like diabetes or prediabetes, medications such as GLP-1 receptor agonists (e.g., Semaglutide or Tirzepatide) are often considered first, as they can lead to significant weight loss, improve metabolic health, and may be more sustainable with ongoing use.

However, suppose your weight has been resistant to medical therapy or you have severe obesity with multiple comorbidities. In that case, bariatric surgery (such as gastric sleeve or gastric bypass) is a more effective long-term option, offering durable weight loss and improvement in metabolic diseases.

Before surgery, you will need a comprehensive physical evaluation, psychological assessment, nutritional counselling, and sometimes a cardiac or pulmonary evaluation. Discussing your goals, medical history, and readiness for lifestyle change with your doctor or a bariatric specialist will help determine whether medication, surgery, or a combination approach is best suited for you.

I hope this information is helpful to you.

Thanks.
