Only a few effective medications exist, and they should be managed by healthcare professionals. There are no over-the-counter.
weight loss drugs that are medically safe, so it’s crucial to avoid self-medicating.
&nbsp;

<ul>

<li>BMI: Greater than 37.5 kg/m²</li>

&nbsp;
<h2>How Does Weight Loss Surgery Work?</h2>
Weight loss surgery operates on three main principles:
<ol>
<li>Reducing Food Intake: The size of the stomach is reduced, leading to quicker feelings of fullness.</li>
<li>Decreasing Nutrient Absorption: The surgical alteration of the digestive tract reduces the time food spends in contact with digestive enzymes and absorption sites.</li>
<li>Hormonal Adjustment: Surgery can help regulate hormones that control hunger and satiety, improving overall metabolic function. 
</li>
</ol>
These mechanisms collectively lower the caloric intake significantly more than traditional methods of dieting alone. As a result, the body begins to burn stored fat, leading to weight loss and improvement in various health functions. Many patients even find that they no longer suffer from obesity-related conditions.
 
In today&#8217;s world, two standard and globally recognized methods of weight loss surgery are gaining popularity:
<ul>
<li>Laparoscopic Sleeve Gastrectomy: This procedure involves reducing the size of the stomach significantly while keeping enough stomach tissue to meet the body&#8217;s needs. By removing the part of the stomach that produces hunger hormones, this surgery effectively decreases both food intake and hormonal signals related to appetite.</li>
<li>Laparoscopic Gastric Bypass: This method combines stomach size reduction with rerouting the digestive tract. It skips most of the stomach and parts of the small intestine responsible for high nutrient absorption. While it requires more steps and takes longer to perform, it can lead to more significant weight loss and better resolution of obesity-related diseases, especially diabetes.</li>
</ul>
Some may worry about long-term nutritional deficiencies post-surgery. However, as long as patients take prescribed vitamins and minerals, they should not experience any deficiencies. 
 
In the initial weeks after surgery, patients can lose nearly ten kilograms, with a total weight loss of 50-80% of excess weight or 18-40% of their current weight within the first 6 to 12 months. After this peak, weight may stabilize or fluctuate slightly based on individual lifestyle choices and behaviors. Thus, surgery serves as a powerful tool to jumpstart the weight loss journey. 
 
Both surgical methods are less intimidating than they may seem. They are performed laparoscopically under general anesthesia, resulting in small incisions, minimal pain, and quick recovery. The sleeve surgery typically lasts 1-2 hours, while the bypass takes about 3-5 hours. Most patients spend only 2-3 days in the hospital before returning home. 
 
The risk of complications is low, ranging from 0-7%. The choice of surgical method is tailored to each individual, taking into account their unique circumstances. Post-surgery, patients should rest at home for about 2-4 weeks to adapt to their new digestive system. Rapid weight loss can lead to improvements in various health conditions, often allowing patients to reduce their medication for chronic illnesses.

<h2>Ongoing Support and Care</h2>
Weight loss surgery is just the beginning of a transformative journey. It simplifies dietary control, particularly for individuals with significant obesity or related health conditions that make weight loss challenging. Long-term success in maintaining weight loss relies on ongoing commitment to self-care.
&nbsp;
Each person&#8217;s health status, lifestyle, and preferences vary, which is why a multidisciplinary healthcare team—including specialists, dietitians, and physical therapists—provides continuous support and guidance throughout the surgical process and recovery.
