Bariatric Surgery - Causes, Symptoms, Diagnosis

Bariatric surgery is often recommended for individuals struggling with severe obesity when lifestyle changes and traditional weight-loss methods have proven ineffective. The primary causes of severe obesity include genetic factors, hormonal imbalances, and metabolic disorders. In some cases, psychological factors such as emotional eating and stress can contribute to excessive weight gain. Chronic conditions like Type 2 diabetes, heart disease, and sleep apnea may also exacerbate the need for surgical intervention. Bariatric surgery addresses the

Symptoms and Diagnosis

Patients seeking bariatric surgery typically present with symptoms such as excessive weight gain, difficulty in performing daily activities, and obesity-related health conditions like hypertension, diabetes, and joint pain. A thorough diagnostic evaluation is essential to determine the appropriateness of surgical options. This assessment usually includes a comprehensive medical history, physical examination, and diagnostic tests such as blood work and imaging studies. Additionally, psychological evaluations and consultations with nutritionists may be conducted to ensure that patients are prepared for the lifestyle changes post-surgery. This multi-faceted approach helps in tailoring a personalized treatment plan and maximizing the long-term success of bariatric procedures.

Procedures & Interventions

Gastric Bypass (Roux-en-Y)

This procedure involves creating a small stomach pouch and rerouting the small intestine to connect to the pouch. By reducing the stomach size and bypassing a significant portion of the intestine, it limits food intake and reduces nutrient absorption. This leads to substantial weight loss and improved control of obesity-related conditions like diabetes.

Sleeve Gastrectomy

In sleeve gastrectomy, approximately 75-80% of the stomach is removed, leaving a tube-like structure or "sleeve." This significantly reduces the stomach's capacity, resulting in reduced food intake and hunger. The procedure also impacts hormones that regulate appetite and metabolism, contributing to effective weight loss.

Adjustable Gastric Band (Lap-Band)

This method involves placing a silicone band around the upper part of the stomach to create a small pouch. The band can be adjusted to control the stomach's size and restrict food intake. While it is less invasive, it requires regular adjustments and is less commonly performed compared to other procedures due to lower weight loss outcomes.

Biliopancreatic Diversion with Duodenal Switch (BPD/DS)

This complex procedure involves removing a large portion of the stomach and rerouting the small intestine to reduce nutrient absorption. It combines both restrictive and malabsorptive elements, resulting in significant weight loss and improvement in obesity-related conditions. Due to its complexity, it is typically reserved for patients with severe obesity.

Intragastric Balloon

An intragastric balloon is a non-surgical option where a deflated balloon is inserted into the stomach and then inflated. This device helps to induce a feeling of fullness and limits food intake. It is often used as a temporary solution or as a pre-operative measure to aid weight loss before other surgical procedures.
