Bariatric Surgery

Obesity has become an epidemic of global proportions. Many people are living with a high risk of dying from complications of their obese status, or living with a disability and/or a psychosocial stigma that prevents them from enjoying a satisfying life. The general recommendation to morbidly obese patients to lose 10% of their initial body weight, is well known to have a positive impact and therefore reducing their cardiovascular risk.

Conventional obesity management such as diet

control and exercise has limitations in patients with morbid obesity. Weight loss surgery, therefore, is another

option to lose weight in morbidly obese patients. Weight loss surgery, also

known as bariatric surgery, can lead to significant weight loss and help

improve or even cure many obesity-related conditions, such as type 2 diabetes or high blood pressure.

What is bariatric surgery?


Gastric bypass and other weight-loss surgeries — known collectively as bariatric surgery — involve making changes to your digestive system to help you lose weight. Bariatric surgery is done when diet and exercise haven’t worked or when you have serious health problems because of your weight. Some procedures limit how much you can eat. Other procedures work by reducing the body’s ability to absorb nutrients. There are also other procedures which can do both.


It is now clear that caloric restriction per se does not explain all the reduction in stored fat mass after surgery. A number of gastrointestinal hormones, including glucagon-like peptide (GLP)-1, peptide YY, oxyntomodulin, GLP-2, glucose-dependent insulinotropic polypeptide, ghrelin etc., can play roles in energy homeostasis and could be involved in bariatric surgery-related weight loss and weight loss maintenance.


Who is a candidate for weight loss surgery?


Indications for bariatric surgery for people with Asian ethnicity is BMI >37 or BMI >32.5 with T2DM or two significant obesity related co-morbidities.

Qualifications for bariatric surgery in people with European or American descendents include:



  1. BMI ≥ 40, or more than 100 pounds overweight.
  2. BMI ≥ 35 and at least one or more obesity-related co-morbidities such as type II diabetes (T2DM), hypertension, sleep apnea and other respiratory disorders, non-alcoholic fatty liver disease, osteoarthritis, lipid abnormalities, gastrointestinal disorders, or heart disease.
  3. Inability to achieve a healthy weight loss sustained for a period of time with prior weight loss efforts.

For example, an adult who is 5’11″ tall and weighs 290 lbs would have a BMI over 40. Calculate your BMI. – https://asmbs.org/patients/who-is-a-candidate-for-bariatric-surgery


How to diagnose obesity?

Ovarian Cysts: A Hidden Threat Every Woman Should Know

These days, who would have thought that “ovarian cysts” would become a silent danger women need to be aware of? What’s even more concerning is that ovarian cysts often present no clear warning signs. Many women may be unaware that they have an ovarian cyst until they experience severe symptoms such as intense menstrual cramps, irregular periods, abdominal bloating, noticeable lumps in the pelvic area, or severe pain during intercourse. If left untreated, this condition can potentially be life-threatening. Unveiling the Secrets of Ovarian Cysts with a Specialist Professor Emeritus Dr. Sangchai Preutthipan, a specialist in reproductive medicine and laparoscopic surgery from Praram 9 Hospital, explains that the “ovaries” are small, thumb-sized organs responsible for producing eggs each month. With each ovulation, a fluid-filled sac forms around the egg. Sometimes, these sacs don’t dissolve as they should, leading to cyst formation. There are several types of ovarian cysts, including those caused by ovarian dysfunction, tumor-related cysts, endometriosis cysts (also known as chocolate cysts), cysts resembling other body tissues, and even cancerous cysts. Dr. Sangchai further notes that women of reproductive age up until menopause are at risk for ovarian cysts. Around 30-35% of women develop cysts due to ovarian dysfunction, while 20% develop tumor-related or chocolate cysts. Approximately 15% may have cysts that resemble other tissue types, and 1-5% are diagnosed with cancerous cysts. Each type of cyst carries different health risks.
