What’s the Average Weight Loss After Gastric Bypass Surgery?

Thousands of Americans have had bariatric surgery to rapidly reduce weight and keep it off for good. When it comes to helping obese individuals shed pounds, surgery has proven to be more beneficial than diet and exercise alone. Some patients considering gastric bypass want to know the approximate weight loss that can be expected.

The average weight loss with gastric bypass surgery after the first year, patients should anticipate losing between 50 and 60 percent of their extra weight. The difference between your present and goal weight is your excess weight. During the first year, a patient who starts at 400 pounds but wants to go down to 200 might expect to drop between 100 and 120 pounds. Patients often lose the most weight in the first month following gastric bypass. However, the amount lost may vary depending on the patient’s starting weight. Following surgery, weight loss typically levels out between the 18th and 36th month. 

The Mechanics of Gastric Bypass

In the middle of the 20th century, surgeons invented gastric bypass surgery, also called roux-en-Y gastric bypass (RYGB), to treat obesity. While not a cure, they found a surgical therapy for persistent obesity that works well if the patient follows post-operative care guidelines. With gastric bypass surgery, a patient’s stomach is surgically divided in half, creating a smaller pouch restricting the patient’s food intake. The surgeon then attaches the bottom half of the small intestine to the stomach, limiting the food the body can digest and absorb. 

Overall, the patient’s eating capacity decreases, and the calories they ingest are of worse quality. Therefore, patients consume far fewer calories than they expend, leading to fast weight reduction. Although, certain patients have reported even early weight reduction plateaus. But why do they hit a wall and even gain weight?

The Causes of Weight Loss Stagnation

It’s Difficult To Break Established Routines

Most people who are very obese and want to have bariatric surgery also struggle with food addiction. Or they resort to other unhealthy practices concerning food, such as binge eating. Consistent repetition of these actions over time can cement them into habits. Patients undergoing bariatric surgery are strongly encouraged to get mental health therapy before and after the procedure to ensure they are emotionally and psychologically ready to make the lifelong commitment required to eliminate unhealthy eating practices.

Insufficient Physical Activity

As an alternative to exercise, many patients choose the operation in the hopes of achieving weight loss. Patients who have gastric bypass surgery don’t need to exercise to shed pounds, although doing so has been demonstrated to increase the procedure’s effectiveness. Exercising is an excellent alternative to certain unhealthy eating habits and can help a patient lose weight more quickly. It’s also great for bulking up lacking muscle, which may aid in reducing overall body fat and tightening saggy skin.

Some Patients May Need Revision Surgery

While many people reach a plateau after surgery because they revert to their previous, unhealthy ways of living, others are unhappy with the results. It is because some people require bariatric revision surgery. A patient could require revision surgery for a variety of reasons. A consultation with a bariatric surgeon is recommended if you suspect you need revision surgery.

Why Do People Have Gastric Bypass Surgery?

Individuals who are morbidly obese and have failed to lose weight with diet and exercise should consider gastric bypass surgery. Patients who make the life-changing decision to have gastric bypass surgery must:

  • Make significant adjustments to how they live.
  • Reduce the serving sizes.
  • Consider exercising a regular part of your routine.

Patients with a high BMI (Body Mass Index) and other obesity-related health problems may be candidates for this surgery.

Progress Months After Surgery

3 Months After the Surgery

Rapid weight loss is expected within the first three months following surgery. The liquid diet and the modifications to the digestive system sustain rapid weight loss. A patient can lose about 25-35% of extra weight if a patient loses 30-40 pounds.

6 Months After Surgery

After around three months, the weight reduction may slow, but most patients will still lose 1-2 pounds each week. Most people lose about 45 percent of their excess weight after six months.

18 Months After Surgery

According to statistical norms, patients who stuck to their weight-reduction plans should have reached or surpassed their target weight by now. By the 24-month mark, most patients had lost 60% of their excess weight, and some had lost as much as 70% to 80%.

Pros of Gastric Bypass Surgery

1. Many patients who have gastric bypass surgery lose a lot of weight quickly after the operation and often keep losing weight for months or even years afterward.

2. Reducing or eliminating several diseases associated with obesity, such as diabetes, hypertension, and sleep apnea.

3. Many persons who have gastric bypass surgery report increased happiness and general improvement in their mood after the procedure.

Dumping Syndrome

The dumping syndrome is one of the potential complications that might arise after gastric bypass surgery. It’s common after consuming sugary or fatty foods when the stomach’s contents are pushed through the small intestine too rapidly.

The effects of dumping syndrome include:

• Cramps

• Diarrhea

• Lightheadedness

• Nausea

• Puking

• Sweating

• Weakness

Before gastric bypass surgery, you and your bariatric surgeon will discuss all potential risks, consequences, and other weight reduction surgical choices. We suggest consulting with your surgeon if you have any concerns or questions regarding gastric bypass.

Keep In Mind

Remember that the typical range is 50-60%. Some people suffer significantly more severe losses than others. Setting realistic goals, resolving to alter one’s lifestyle, and maintaining motivation are the three pillars of gastric bypass success.

Do not be disheartened if your total turns out to be smaller than you had hoped. Many people are shocked to learn that weight loss surgery cannot magically transform them from 250 to 120 pounds. Although gastric bypass isn’t a silver bullet, surgery can help you reach a healthy weight. You’ll be able to exercise more, remain on your feet for longer, take more pleasure in life, and keep the weight off far more quickly after you reach your goal weight.

Dropping that first fifty pounds is the most challenging. When you see the scale moving in the right direction, it will urge you to keep making healthier food choices and to boast about your achievements to your friends and family. All the best!
