Bariatric Surgery Pros

Obesity rates are out of control in the United States and have been getting worse year over year. There are many factors contributing to this decline in our Nation’s health but fortunately, due to advancements in medical technology, obese individuals have several surgical and non-surgical choices that can help them lose weight.

1. Losing Weight Can Help You Live Longer

Bariatric surgery can save or extend a patient’s life. Many patients suffer from weight-related diseases and disorders that can be alleviated through bariatric surgery.

The Journal Of The American Medical Association published a study contrasting patients who had weight loss surgery with those that did not, taking into consideration their age, gender, BMI, and obesity-related conditions. The study concluded that those who lost weight after having bariatric surgery had a longer lifespan.

2. Reduces Risks For Heart Disease, Hypertension, and Diabetes

A study presented by The American Society for Metabolic Surgery reported that Individuals who underwent bariatric surgery experienced a 40% reduction in potential risk for coronary artery disease and one year later 40% of the patient group experienced the complete remission of type 2 diabetes, and 44% of these patients no longer exhibited any symptoms of high blood pressure.

Type II Diabetes
The Journal of Clinical Endocrinology & Metabolism (JCEM)published the results of a study that further established a link between obesity and type II diabetes and the effect that losing weight plays on the disease. According to the study, over 50% of adults with the disease experienced remission after undergoing gastric bypass surgery and losing weight.
High Blood Pressure
Hypertension is another common comorbidity of obesity and has been the subject of many obesity-related studies that monitor the effects of bariatric surgery on a patient’s blood pressure. Often after losing weight patients need to adjust the strength of their blood pressure medication because as their BMI comes down, so does their blood pressure. One study reported over 30% of the participants had to make medication adjustments and some patients experienced remission.
Sleep Apnea
Obesity and sleep apnea have also been connected in previous studies but a study in Sweden showed that 66% of the patients who lost weight after having gastric bypass surgery showed remission of the condition in a two-year follow-up.
Non-Alcoholic Fatty Liver Disease (NAFLD)
Excess fat can create imbalances in our vital body functions, one of which is insulin resistance. When the pancreas has to work extra hard to manufacture enough insulin to maintain our body’s blood sugar levels, it can result in diabetes. A 2019 study showed that NAFLD is a condition experienced by somewhere between 50% and 75% of all obese individuals and they are 2 ½ times more at risk for heart disease.
Carrying excess weight causes wear-and-tear on our joints and many times it can affect an individual’s mobility. Osteoarthritis is the term that is used to describe this condition. A study that observed patients who were suffering from obesity-related health conditions and lost weight after bariatric surgery reported that even a small loss of weight (10%) can go a long way in reducing the symptoms related to osteoarthritis.
A woman’s fertility can be affected by obesity in many ways. Excess fat that is stored produces estrogen and excess estrogen can disrupt the reproductive cycle. Many women have resumed normal cycles of menstruation and ovulation after undergoing bariatric surgery and losing weight.
Promotes Sustained Weight-loss
The American Society for Metabolic and Bariatric Surgery (ASMBS) reported that individuals who undergo bariatric surgery to lose weight can maintain at least half their weight loss long-term.
Depression and Self Esteem
Most patients develop a more positive body image after losing weight after bariatric surgery. Patients who underwent cosmetic surgery to repair loose skin and other obesity-related damage reported feeling more self-assured and had a more positive outlook. Continuing to follow the lifestyle changes that led to their weight loss after surgery including eating a healthy balanced diet and exercising also promotes feelings of positivity and fulfillment.

Bariatric Surgery Cons

Even with the advancements in bariatric surgery such as laparoscopic procedures, there are still associated risks. Some of the risks that surround bariatric surgery are common and well-known while, others may come as a surprise. Some patients experience some downsides of bariatric surgery that they were not expecting. Having an idea of some of the cons associated with bariatric surgery can help patients to set expectations for their “new normal” after bariatric surgery.

General surgical risks:

  • Side effects from general anesthesia;
  • Excessive bleeding;
  • Infection of incisions or internal infections;
  • Risk of DVT (Blood Clots).

Downsides Of Life After Bariatric Surgery

When researching the pros and cons of bariatric surgery, most of the results you will find regarding the cons are surgical complications that may arise during or after the surgery. But have you thought about what your life might look like after your bariatric surgery? There may be some discouraging things that occur that you have not considered, but if you have a plan in place for how to address them if they arise, you are more likely to persevere through to success. Some of the downsides of bariatric surgery to consider include:

Having weight loss surgery and going through the recovery is just the beginning of a life-long journey and will require a significant amount of hard work. The surgery is just a tool to help your hard work pay off and to ensure success, you will be required to make and follow significant lifestyle changes. Making all these changes can be physically and emotionally exhausting for many patients.
Alterations To Your Social Life
Many individuals who undergo bariatric surgery have unhealthy eating habits and must make significant changes to their diet and behavior patterns. To be successful in losing weight it may be necessary to steer clear of social situations that are centered around eating. For instance, you meet a group of friends every Friday night after work for tacos and beer. Your new lifestyle does not support taco and beer night, so can you go and spend time with your friends without making unhealthy choices or would it be easier for you to avoid the situation entirely?

Friends and family who have never experienced weight loss surgery often do not understand what you are going through and do not know how to best support you. This can be a sticky situation because friends may become frustrated with you and it may come down to a choice between you staying on track with your weight loss or socializing with these friends.

Many weight loss patients join support groups to help them get through tough situations like this. These groups are offered both in-person and online and can provide a forum of like-minded people who are experiencing the same issues or have been where you now find yourself.

Psychological Issues Have Remained
Many patients who struggle with obesity have underlying psychological issues that cause them to eat to gain emotional comfort or relieve stress. Undergoing bariatric surgery is not a magic cure and if a patient has unrealistic expectations in thinking otherwise, it may result in disappointment. While losing weight will ultimately give these patients energy to function and can improve their body image and self-esteem, it is not able to address deep-rooted issues that may have contributed to their obesity. Patients are encouraged to work with a professional during their weight loss journey. One who can help support and provide guidance in addressing issues where behavior modification is necessary so they can achieve physical and emotional wellness.
Body Image
After undergoing bariatric surgery many patients are anticipating wearing new cute clothing, social outings where they feel good about themselves Etc. Reality is sometimes the complete opposite and they may feel like they traded one embarrassing issue for another as they worked so hard just to feel worse about the way they look.

Most weight loss patients have carried extra weight for years and the sudden loss of a significant amount leaves behind stretch marks, sagging breasts, and a tremendous amount of loose skin causing anxiety and perhaps more emotional distress than their previous weight.

Knowing these issues may arise can help patients create a long-term plan of care for themselves after their bariatric surgery. Cosmetic procedures can correct, eliminate or reduce the visibility of many issues that arise after a massive weight loss. Most cosmetic surgeons have flexible financing programs to help make these procedures affordable for their patients.

Reduced Tolerance To Alcohol
AUD or alcohol use disorder affects some patients long-term after undergoing bariatric surgery. It is a condition that occurs because of the changes made to the body during certain types of bariatric surgery. The body processes alcohol differently than it had previously and the patient can become drunk much faster than they would have before their surgery. It can also influence and promote addiction to alcohol. In some cases, doctors recommend patients totally abstain from alcohol use.
Hair Loss
Patients often experience hair loss after undergoing any type of major surgery. This occurs for many bariatric surgery patients as well and can come as quite a shock. Hair grows in cycles; it has a growth phase, a resting phase, and a shedding phase. Surgery often interrupts this process and causes the shedding phase to linger. This is usually temporary and will resolve itself but can be concerning.
