Obesity & Weight Management

Doctors often use Body Mass Index (BMI) to determine if someone is underweight, at a healthy weight, overweight, or obese. BMI is calculated by dividing weight in kilograms by height in meters squared. According to the World Health Organization (WHO), a BMI between 25 and 29.9 indicates overweight, while a BMI of 30 or higher denotes obesity. 

If your BMI falls into the overweight or obese categories, it's advisable to consult a healthcare professional. Obesity increases the risk of serious health issues such as type 2 diabetes, heart disease, certain cancers, and can lead to a shorter lifespan compared to individuals with a healthy weight. 

Successful weight loss typically involves a combination of dietary changes and increased physical activity. It's essential to adopt a sustainable approach rather than relying on short-term diets. Studies have shown that various diets, such as the Atkins, Zone, or Weight Watchers, can be effective if they result in a calorie deficit and are maintained over time. Similarly, increasing physical activity—like walking, dancing, or gardening—helps burn more calories and supports weight loss 

In some cases, healthcare providers may recommend weight loss medications or surgery, especially if lifestyle changes alone haven't been effective. Medications may work by reducing appetite or altering how the body processes food. These are typically considered for individuals with a BMI of 30 or higher, or 27 and above with related health conditions .

Weight loss surgeries, such as gastric bypass or sleeve gastrectomy, are more effective for long-term weight loss compared to medications and lifestyle changes alone. Studies have found that bariatric surgeries result in about 30% weight loss one year post-operation, with patients maintaining a 25% weight loss up to 10 years

Considerations Before Surgery

Before opting for weight loss surgery, it's crucial to discuss with your doctor:

• The expected amount of weight loss and the timeline.
   
• Potential risks and complications associated with the procedure.
   
• Necessary lifestyle and dietary changes post-surgery.
   
• The need for lifelong nutritional supplementation, as some surgeries can affect nutrient absorption.

Remember, a comprehensive approach involving medical guidance, lifestyle changes, and, when appropriate, medical treatments can help achieve and maintain a healthy weight.
