9 Interesting Facts About Weight Loss Surgery
Obesity has existed throughout human history — there are records of obesity even in medieval times. But in the past 20 years, it has grown into a global health epidemic, recognised by the international medical community as a chronic disease that requires proper medical treatment.
Weight loss (bariatric) surgery is the most effective medical treatment for obesity today. Here are 9 interesting facts about weight loss surgery that many people don’t know.
1. Bariatric surgery has ancient roots
Although modern bariatric surgery began in the 1950s, historical evidence shows that early forms of weight-loss surgical techniques were being attempted as early as the 10th century.
The first modern laparoscopic gastric bypass was performed in 1994 by Dr. Alan Wittgrove in the United States, marking a huge leap in minimally invasive weight-loss surgery.
2. Over half a million weight-loss surgeries were performed in 2021
According to the IFSO Global Registry, more than 598,000 bariatric surgeries were performed worldwide in 2021 — and the number continues to rise each year as obesity rates increase. The IFSO Global Registry aggregates data from contributing national/regional registries; not all countries participate fully, so totals may be underestimates.
3. Most patients undergoing bariatric surgery are women
Globally, women represent the majority of bariatric surgery patients.
However, men who choose surgery often report higher rates of:
- Type 2 diabetes
- Obstructive sleep apnoea (OSA)
- High cholesterol
- Hypertension
While women more often report depression as a co-existing condition.
4. Gastric sleeve is the most common weight-loss surgery recent years
In 2021:
- ~60% of bariatric surgeries worldwide were sleeve gastrectomies, rates are growing year by year,
- followed by Roux-en-Y gastric bypass procedures.
- Both surgeries are considered highly effective and safe.
5. Weight-loss surgery can resolve or dramatically improve many obesity-related health problems
Including:
- Type 2 diabetes
- High blood pressure
- Sleep apnoea
- Asthma
- PCOS
- Joint and back pain
- High cholesterol
Many patients reduce or stop medications within months after surgery.
6. Bariatric surgery is the most effective obesity treatment available today
Neither diets, medications, injections, nor exercise alone come close to the long-term weight loss outcomes of bariatric surgery — especially for individuals with severe obesity stage 3.
7. Weight loss surgery improves mental health and quality of life
Research shows improvements in:
- self-confidence
- mobility
- emotional wellbeing
- energy levels
- social functioning
Many patients describe it as “getting their life back”.
8. Weight loss surgery can extend life expectancy
Recent studies show that bariatric surgery can prolong life by an average of 9 years compared to individuals with severe obesity who do not receive any treatment.
9. Bariatric surgery is extremely safe
Bariatric surgery today has a very low mortality rate: 0–0.11% (IFSO Global Report 2022).
This makes it as safe or safer than many common surgeries, including gallbladder removal and hip replacement.
