Gastric Bypass Surgery: Considering the Pros and Cons

The alarming rise of obesity has become a dire threat to public well-being. Its damaging impact on both physical and mental health highlights the urgent necessity for successful intervention strategies. Gastric bypass surgery offers hope of sustainable weight loss that improves health outcomes, and each year, thousands of people undergo this life-altering procedure.

This post is for anyone considering bariatric surgeries for themselves or someone they love and explores both the advantages and drawbacks associated with gastric bypass procedures. By considering both sides, you can make an informed decision on whether a gastric bypass procedure is suitable for you on your journey toward better health.

What Exactly Is Gastric Bypass Surgery?

Gastric bypass surgery is a medical procedure designed to help individuals struggling with obesity successfully lose weight over time. This procedure modifies the digestive system—particularly the stomach and small intestine—to limit food intake while altering the body’s absorption capabilities.

Gastric bypass surgery entails creating a small pouch at the top of the stomach by dividing it. This pouch then becomes the primary location for food consumption, significantly decreasing how much can be eaten at once. Furthermore, part of the small intestine is rerouted directly into this new pouch, thus bypassing much of the stomach and upper intestine altogether.

Gastric bypass surgery works to achieve weight loss through two primary mechanisms. First, this method limits how much food can be eaten at once while simultaneously bypassing parts of the digestive tract where calories tend to accumulate.

Advantages of Gastric Bypass

Gastric bypass promotes weight loss by restricting how much food your stomach stores and by altering how your digestive tract absorbs nutrients and calories from food, both of which increase satiation levels in your stomach. This process essentially helps you shed those unwanted pounds.

Gastric bypass surgery affects hormones that control feelings of fullness and hunger. It also changes the brain’s response when you eat. Gastric bypass patients feel fuller for longer, enjoy eating less, and are less prone to emotional eating.

Individuals who undergo gastric bypass surgery report that they often notice a change in their eating habits, such as:

  • They have fewer cravings for high-fat and sugary foods.
  • They don’t crave carbohydrates and sugars.
  • They have reduced tolerance to specific foods/beverages such as dairy products, sweets, meat, or carbohydrates.

Medical Benefits

Gastric bypass surgery can reduce the risk of obesity and health problems such as:

  • Gastroesophageal reflux disease
  • Heart disease
  • High blood pressure
  • Hyperlipidemia, or high cholesterol
  • Pain relief for musculoskeletal disorders
  • Obstructive sleep apnea
  • Type 2 diabetes
  • Stroke
  • Cancer
  • Infertility

It’s also reported that 74.8% to 79.4% of patients experienced complete T2DM remission at 1 year and 3 years after bariatric surgery. 

Disadvantages of Gastric Bypass

Short-Term Complications of Gastric Bypass Surgery

  • Excessive bleeding
  • Infection
  • Anesthesia adverse reactions
  • Blood clots
  • Perforation
  • Strictness
  • Lung or breathing problems
  • Leaks in your digestive system

Long-Term Complications

Gastric bypass patients may find that the foods they used to enjoy now taste bitter or have an unpleasant consistency. They may also smell bad. Some gastric bypass patients also experience “dumping syndrome” due to hormonal changes. This condition causes food to be absorbed into the small bowels too quickly, especially after eating high-carbohydrate and/or sugary meals. Dumping syndrome is a condition that can lead to several unpleasant symptoms, such as:

  • Constipation
  • Confusion
  • Diarrhea
  • Changes in mood
  • Nausea
  • Sweating
  • Vomiting

Patients with dumping syndrome learn quickly which foods they can tolerate and which ones they cannot. The way they feel following a meal can also help them control what they eat and how much.

Malnutrition and Nutrient Deficiencies after Gastric Bypass

Once surgery has taken place, nutritional deficiencies are possible, with B12, folate, iron, calcium, thiamine, and vitamin D levels possibly falling below pre-surgery levels. Zinc, copper, selenium, and Vitamin C levels may also experience slight decreases, although no serious concerns should arise from them.

Due to reduced absorption, surgery increases your risk of nutritional deficiency. To protect yourself from deficiencies following surgery and minimize nutritional deficiency risks, you must continue taking vitamin and mineral supplements for the rest of your life. You must also continuously keep in touch with both your surgeon and dietitian so they can monitor your nutritional status closely.

In Closing

Gastric bypass surgery should be approached carefully, taking into account many different aspects. While it can be successful at treating obesity, you must carefully weigh any possible side effects or risks that come with this form of procedure. We advise speaking to a doctor and exploring all available options before making your final decision about this method of weight loss.

Eating right and exercising regularly should always be the first avenue explored for attaining desired health outcomes. If all other efforts have failed, gastric bypass surgery could be your answer. Be sure that you fully comprehend its scope and implications prior to proceeding with surgery. If this option seems suitable to you, talk with your physician immediately about undergoing one.
