Obesity surgeries, also known as bariatric surgeries or weight loss surgeries, are medical procedures performed to help individuals who are severely overweight or obese achieve significant and sustained weight loss. These surgeries are typically recommended for individuals with a body mass index (BMI) of 40 or higher, or those with a BMI of 35 or higher who have obesity-related health conditions such as type 2 diabetes, hypertension, or sleep apnea.
There are several types of obesity surgeries, the most popular are:
▶ Gastric Bypass Surgery:
- In this procedure, the surgeon creates a small pouch at the top of the stomach and connects it directly to the small intestine, bypassing a portion of the stomach and the first part of the small intestine.
- Gastric bypass surgery reduces the amount of food the stomach can hold and alters the way nutrients are absorbed, leading to reduced calorie intake and weight loss.
- It also has metabolic effects, such as improving insulin sensitivity and hormone regulation, which can help improve or resolve conditions like type 2 diabetes.
▶ Sleeve Gastrectomy:
- During a sleeve gastrectomy, a large portion of the stomach is removed, leaving a small, sleeve-shaped pouch.
- This procedure restricts the amount of food that can be consumed and reduces hunger by decreasing the production of appetite-regulating hormones.
- Sleeve gastrectomy is less complex than gastric bypass and does not involve rerouting the intestines, but it can still result in significant weight loss.
▶ Gastric Balloon:
- A gastric balloon is a temporary, nonsurgical option for weight loss in which a deflated balloon is inserted into the stomach and then inflated to occupy space and create a feeling of fullness.
- The balloon is typically removed after six months, and its presence helps patients eat smaller portions and make dietary changes to facilitate weight loss.
- Gastric balloons are often recommended for individuals who are not candidates for or do not wish to undergo surgery.
▶ Stomach Botox Injection:
- Stomach botox injection involves the direct administration of botulinum toxin into specific muscles within the stomach wall.
- Botulinum toxin blocks the release of acetylcholine, a neurotransmitter responsible for muscle contraction, inducing temporary relaxation of the stomach muscles.
- This procedure is primarily used to treat gastrointestinal disorders such as gastroparesis, improving gastric motility and alleviating symptoms such as nausea, vomiting, and bloating.

Obesity surgeries are intended to complement lifestyle changes such as diet and exercise and are usually considered as a last resort when other weight loss interventions have been ineffective. These procedures can lead to significant improvements in overall health, including reductions in obesity- related conditions such as diabetes, hypertension, sleep apnea, and joint pain. |
Benefits of obesity surgery are:
▶ Significant Weight Loss: All obesity surgeries are effective in promoting significant and sustained weight loss. Patients typically experience substantial reductions in body weight, which can lead to improvements in obesity-related health conditions and overall quality of life.
▶ Improvement or Resolution of Obesity-related Health Conditions: Obesity surgeries often result in the improvement or resolution of obesity-related health conditions such as type 2 diabetes, hypertension, sleep apnea, high cholesterol, and joint pain. This can lead to reduced medication requirements, better disease management, and lower risk of complications associated with these conditions.
▶ Enhanced Metabolic Health: Many obesity surgeries have metabolic effects beyond weight loss. Procedures such as gastric bypass and sleeve gastrectomy can improve insulin sensitivity, blood sugar control, and hormonal regulation, leading to better metabolic health and reduced risk of metabolic syndrome and cardiovascular disease.
▶ Reduction in Mortality Risk: Obesity surgeries have been associated with reduced mortality risk compared to non-surgical interventions in individuals with severe obesity. By promoting weight loss and improving obesity-related health conditions, these surgeries can lower the risk of premature death from obesity-related causes such as cardiovascular disease, stroke, and certain cancers.
▶ Reduction in Medication Dependence: Following obesity surgery, many patients experience reductions in medication requirements for obesity-related health conditions such as diabetes, hypertension, and hyperlipidemia. Some individuals may even achieve complete remission of these conditions, leading to decreased reliance on medications and associated cost savings.
▶ Long-term Maintenance of Weight Loss: While maintaining weight loss can be challenging, obesity surgeries have been shown to provide long-term benefits for many patients. Studies have demonstrated sustained weight loss and improved weight maintenance over several years following surgery, especially when coupled with lifestyle modifications and ongoing support.
It's essential for patients considering any obesity surgery to consult with a board-certified plastic surgeon experienced in these procedures to discuss their options, expectations, and any potential risks or complications. Obesity surgeries can lead to significant improvements in overall health, including reductions in obesity-related conditions such as diabetes, hypertension, sleep apnea, and joint pain.
