Pros And Cons Of Weight Loss Surgery

Pros and Cons of Weight Loss Surgery

Surgery has historically remained the greatest tool of medical science that has saved lives for eons, even though it carries some risk of complications. This foundational principle also applies to bariatric surgery. According to the CDC, obesity is a leading cause of numerous chronic as well as life-threatening diseases. The golden news is that obesity can be treated with bariatric surgery.

When you consider the pros and cons of weight loss surgery, its benefits in terms of your health, longevity and quality of life will far outweigh the risk of temporary side effects and complications. For this reason, the medical community worldwide now encourages patients to consider the pros and cons of bariatric surgery and choose this procedure to eliminate obesity.


Is weight loss surgery safe?

It is important to know what are the pros and cons of bariatric surgery and whether it is safe for you. In general, the two primary forms of weight loss surgery – gastric sleeve and gastric bypass – are both considered highly safe. But two vital pre-requisites to a safe procedure are that you should be an eligible candidate and the bariatric surgeon you work with should be qualified to perform the type of surgery you are choosing.

Lower Risk with Laparoscopic Surgery

Bariatric surgery risks over the years have dramatically reduced with the introduction of laparoscopic technique. When you are considering the pros and cons of weight loss surgery, you should look at whether your surgeon will perform the procedure laparoscopically. This technique is less invasive compared to open surgery, requiring very small incisions. As the surgeon is able to view the underlying structures on a monitor outside, they can perform the procedure with higher precision, causing less tissue trauma.

Gastric Sleeve has a Higher Safety Profile

You should evaluate different types of bariatric surgery pros and cons because the safety profile in each case differs. In comparison to gastric bypass and duodenal switch procedures, gastric sleeve surgery is considered much safer with minimal risk of complications. Gastric sleeve does not involve any changes to the small intestine, and it will only require partial stomach tissue removal. Therefore, the healing is faster and the risk of complications during and after the surgery is substantially lower.

Pros and Cons of weight loss surgery – An overview

Weight loss surgery risks and benefits must be objectively considered for each patient individually in order to determine whether they are a good candidate for it. If your bariatric surgeon finds that you do not suffer from any such medical conditions that will increase your risk of surgery, they may recommend a weight loss procedure for you.

Surgery vs. Lifestyle Interventions

If you are body mass index (BMI) is below 35 and you do not have any obesity-related medical conditions, you may benefit more from lifestyle interventions such as diet control and a fitness regimen to reduce weight. But if your BMI is above 35 with co-morbidities or above 40 without co-morbidities, a bariatric surgery may work ideally to reduce your risk of diabetes, cardiovascular disease, and other conditions. You need to critically evaluate the pros and cons of weight loss surgery in your individual context.


Age, Health, and Personal Goals

The pros and cons of bariatric surgery must also be considered in the context of your age, medical history, and your personal goals. In younger patients, the bariatric surgery risks are lower because their body is more resilient and will recover faster. The medical record of past surgeries and pre-existing ailments will also impact your risk profile. Finally, your surgeon will assess the pros and cons in the backdrop of your personal goals and commitment to follow the post-op diet restrictions for a lifetime.

Benefits of bariatric surgery

An objective analysis of the pros and cons of weight loss surgery will focus equally on the benefits and downsides. The benefits of this surgery are primarily related to your physical health, but you will also achieve indirect benefits in terms of your mental health, self-confidence, and experience an overall improvement in your quality of life.

  • Diabetes: Type 2 diabetes and insulin resistance syndrome are commonly seen among patients with obesity. Weight loss, fatty tissue loss, and increased physical activity following the surgery may lead to diabetes remission.
  • Heart Disease: Obesity is a key risk factor for heart disease and OSA (obstructive sleep apnea). Weight loss, improvement in vascular health, and reduction of neck fat will help reduce the symptoms of heart disease and OSA.
  • Kidney Disease: Patients with obesity-related diabetes and high blood pressure may sometimes suffer from renal failure. This is one of the major indirect bariatric surgery risks, which can be diminished with elimination of obesity.
  • Fatty Liver: NAFLD or non-alcoholic fatty liver disease is frequently found in patients suffering from obesity. Among the pros and cons of bariatric surgery, this is an important ‘pro’ for people who are struggling with poor liver function.
  • Osteoarthritis: This is a severely limiting condition that may be caused or worsened by obesity. Functional and muscoskeletal challenges due to knee, hip and back degeneration can be reversed or controlled with weight loss surgery.
  • Feminine Health: Polycystic ovarian syndrome (PCOS), infertility, menstrual disorders, and female urinary incontinence are some of the conditions women with obesity have to face. Bariatric surgery can resolve these symptoms.
  • Mental Health: People with obesity often suffer from psychosocial, behavioral and mental health issues, such as depression, anxiety, binge eating, and substance abuse, among others. Weight loss surgery promotes their resolution.
  • Longevity: Perhaps the most important benefit to consider when looking at bariatric weight loss surgery pros and cons is its impact on longevity. With resolution of obesity, increased physical activity, healthy diet, and lower co-morbidities, you can expect to live longer.
  • Economic Impact: Patients with obesity and related diseases often suffer from limitations at the workplace, having higher absenteeism, and may be unable to earn to their full potential. Bariatric surgery may indirectly benefit your economic position.

Bariatric surgery risks

Potential risks and limitations should be carefully considered while you are evaluating the different types of bariatric surgery pros and cons. As long as you choose a skilled and experienced surgeon, your physiological weight loss surgery risks will be minimal. However, even then you must be prepared for various potential downsides.

  • Medical Complications: Bariatric surgery is a major procedure, which could potentially cause complications during or after the surgery. Complications may be both short-term and long-term, and may require medical or surgical intervention. You can minimize these bariatric surgery risks when you conscientiously follow your surgeon’s pre- and post-op care guidelines.
  • Weight Loss Failure: While bariatric surgery has a high success rate, a few patients may still experience weight loss failure or weight regain at some stage after the procedure. As long as your surgeon has performed the procedure correctly, you can reverse weight loss failure by strictly adhering to your post-op diet plan. In rare cases, you may require a revision surgery.
  • Loose Skin Tissue: A massive weight loss following your bariatric surgery may sometimes result in excess loose and hanging skin in certain areas of the body. This risk is higher if your skin is less elastic or you undergo the surgery at a later age. If you are bothered by the appearance of loose skin, you may undergo a body lift or skin removal surgery at a later stage.
  • Strained Marriage: While it seems counter-intuitive that a life transforming weight loss surgery can cause marital conflict, it is always possible that you or your spouse may find it hard to cope with the new situation. A therapist can provide you professional counseling, or you may seek help from family or join support groups to limit the emotional impact on your marriage.
  • Mental Health Issues: Although most people will have a stronger mental and emotional health following bariatric surgery, a few people may have an opposite effect, particularly if they encounter weight loss failure. Alcohol or drug abuse, mood swings and depressive disorders, and suicidal thoughts may occur in rare cases. It’s best to see a mental health professional in this situation.
