Severe Obesity

What is Severe Obesity?

Severe obesity (also known as morbid obesity) is a chronic health condition characterized by excessive body fat that significantly increases the risk of serious health problems and reduces quality of life. It is typically defined by a Body Mass Index (BMI) of:

• 40 or higher
• 35 or higher with obesity-related health conditions (e.g., diabetes, high blood pressure)

Severe obesity is not just a cosmetic concern—it is a medical disease that requires long-term management, and in many cases, surgical treatment.

Health Risks of Severe Obesity

Excess weight puts strain on nearly every system in the body. People with severe obesity are at significantly higher risk for:

• Type 2 diabetes
• High blood pressure (hypertension)
• Heart disease and stroke
• Sleep apnea and breathing disorders
• Joint and mobility issues (e.g., osteoarthritis)
• Fatty liver disease (NAFLD and NASH)
• Gastroesophageal reflux disease (GERD)
• Certain cancers (breast, colon, uterine, etc.)
• Depression and anxiety
• Reduced life expectancy

The longer severe obesity goes unmanaged, the greater the impact on daily life, mental well-being, and long-term health.

When is Bariatric Surgery Considered?

Bariatric surgery (also called weight-loss surgery) is a scientifically proven, effective treatment for severe obesity, especially when diet, exercise, and medications have not provided lasting results.

It may be considered for individuals who meet the following criteria:

• BMI ≥ 40, or
• BMI ≥ 35 with obesity-related conditions
• Have tried and failed multiple weight loss attempts
• Are physically and mentally prepared for surgery and lifestyle changes
• Are not dependent on drugs or alcohol
• Are committed to lifelong medical follow-up

Types of Bariatric Surgery

Several safe and effective surgical options are available:

1. Sleeve Gastrectomy (Gastric Sleeve):

Removes a portion of the stomach, reducing its size and limiting food intake. Also affects hunger hormones.

2. Gastric Bypass (Roux-en-Y):

Creates a small stomach pouch and reroutes the digestive tract. Reduces calorie absorption and food intake.

3. Adjustable Gastric Band (Lap Band):

Places a band around the upper part of the stomach to limit intake. But it is less commonly used today.

4. Biliopancreatic Diversion with Duodenal Switch (BPD/DS):

A more complex surgery for very high BMIs, combining restriction and malabsorption.

Benefits of Bariatric Surgery

• Significant and sustained weight loss
• Improvement or resolution of conditions like diabetes, high blood pressure, and sleep apnea
• Lower risk of heart disease and stroke
• Increased energy, mobility, and quality of life
• Reduction in medication use
• Lower long-term mortality rates from obesity-related diseases
   

Most patients lose 50–70% of their excess weight within the first 12–18 months after surgery.

Life After Bariatric Surgery

Bariatric surgery is not a quick fix. It requires:

• Lifelong dietary changes
• Regular exercise
• Vitamin and mineral supplementation
• Ongoing medical follow-up and support
• Psychological readiness and behavioral changes
   

With proper care and commitment, patients can enjoy lasting health benefits and dramatically improved quality of life.
