If your problem with obesity has gotten to the point where health problems are piling up, and you are starting to worry about your future, it’s time to be honest with yourself and do something about your weight. You may feel like the deck is stacked against you. You may have a family history of being overweight. Between working a full-time job and caring for your family, you may feel like there’s no time left to take care of yourself.

No matter what, don’t give up on your dream for a better future. If you are ready to turn your life around, laparoscopic Roux-en-Y gastric bypass surgery can give you the chance to finally lose that weight and discover what it’s like to live free from obesity.

How Gastric Bypass Surgery Works

If you are considering laparoscopic gastric bypass surgery to combat obesity, it is important to understand both how gastric bypass surgery works and the lifestyle changes needed after your weight loss surgery.

Gastric bypass surgery is a serious operation, and our board-certified bariatric surgeon Dr. Shyam Dahiya will help you feel comfortable and confident in your decision. He will explain all the possible risks and complications of weight loss surgery as well as the recovery time for gastric bypass surgery.

Gastric Bypass Surgery Helps You Eat Less

Have you tried to lose weight before, but just couldn’t stick to a diet? Part of the difficulty people with obesity have in losing weight is that years of bad eating habits make dieting a difficult, frustrating process.

You try to eat smaller portions and healthier food, but you just feel hungry all the time. You may do well for several days, then break down and stuff yourself just to finally feel satisfied. It’s a vicious cycle, but you can break it. Laparoscopic gastric bypass surgery can help you actually feel full after eating a small, healthy meal without that irresistible desire to overeat.

The way gastric bypass surgery works is by drastically shrinking the size of your stomach to around 10% of its original size. Your gastric bypass surgeon Dr. Dahiya creates a small pouch at the top of your stomach, which fills up after you eat about half a cup of food. Once that pouch fills, it sends a signal to your brain that your stomach is full, which takes away the feeling of hunger.

Gastric Bypass Surgery Helps You Lose Weight

In addition to helping you limit your portion size, laparoscopic gastric bypass surgery keeps your body from absorbing all the fat and calories in your food. After creating the pouch, Dr. Dahiya connects it directly to the small intestine using an advanced Roux-en-Y gastric bypass surgery technique that is now named after him, the Dahiya Vertical Micropouch™.

Because food passes through your small intestine more quickly, your body has less time to absorb the calories and fat before the food enters the large intestine. This effect is called malabsorption, and further contributes to weight loss.

While both portion restriction and malabsorption are definitely helpful for losing weight, getting to a healthy Body Mass Index (BMI)requires more than bariatric surgery alone. Before you can have gastric bypass surgery, you must already be committed to cultivating healthy habits, especially good nutrition and plenty of exercise. In other words, your goal must be to get healthy, not just to get thin.

Gastric Roux-en-Y Surgery Recovery Time

Deciding to change your lifestyle in order to lose weight with laparoscopic Roux-en-Y gastric bypass surgery or any type of bariatric surgery is a huge and important decision. Naturally, you want to research all your options and find out everything you can about the bariatric surgery process.

One concern that many of our patients have is how long their gastric bypass surgery will take. When you come in for your bariatric surgery consultation at our LA area office, our board-certified Roux-en-Y gastric bypass surgeon Dr. Shyam Dahiya will explain each part of the surgery process and how long it will take.

Recovering After Your Laparoscopic Gastric Roux-en-Y Surgery

To ensure that your recovery time after laparoscopic gastric Roux-en-Y surgery goes quickly and involves less pain, Dr. Dahiya uses the very latest laparoscopic surgery techniques. Laparoscopic surgery uses small, targeted incisions to get your bariatric surgeon’s instruments where they need to go instead of the large, open incisions used in the past. This drastically reduces the risks and complications of weight loss surgery, especially the risk of surgical site infection and hernia.

Dr. Dahiya performs gastric Roux-en-Y surgery at various leading hospitals in the Los Angeles metropolitan area, and you will stay in the hospital for a few days after your weight loss surgery to monitor your healing progress. In order to protect your sensitive digestive system from damage, your diet will be restricted to small amounts of liquid immediately after your gastric bypass procedure.

As your body heals, you will be able to progress from your liquid diet to pureed foods, then to soft foods. It may be several months before you are able to eat solid food, depending on how quickly your body heals. During this time, Dr. Dahiya will check on you regularly for one-on-one follow up care and advise you on how much physical exertion your body can handle. Everyone’s body is unique and may have special challenges, but most patients can return to normal activities within 6-8 weeks.

Diet and Exercise After Your Laparoscopic Gastric Roux-en-Y Surgery

You will continue to have monthly checkups at our office in Lakewood, California for at least a year after your surgery. This not only lets your gastric bypass surgeon Dr. Dahiya check on your healing and weight loss progress, but also allows us to motivate and guide you in sticking to your post-surgery weight loss program.

Successful weight loss with laparoscopic gastric Roux-en-Y surgery depends on your commitment to healthy eating habits and regular exercise. Like they say on The Biggest Loser, you have to decide to change your life in order to save your life. Our nutrition specialist Dr. Jose Mari-Elacion will help you plan healthy, nutritious meals and find time in your schedule for an active lifestyle. With our help and your dedication to healthy habits, gastric Roux-en-Y surgery can be the start of a journey to a brighter, happier future for you and your family.

Common Questions About Gastric Bypass Surgery

What are the age and BMI requirements for gastric bypass surgery in Los Angeles?

While there is no specific age limit for laparoscopic gastric bypass surgery, the risks and complications of weight loss surgery increase with age, especially for patients older than 65. Gastric bypass surgery for patients under 18 is controversial, but may be appropriate for teenagers with morbid obesity.

To qualify for laparoscopic gastric bypass surgery, you must have a Body Mass Index (BMI) of 40 or higher or a BMI of 35-39.9 combined with a serious obesity-related health problem like diabetes or hypertension. However, the FDA may soon expand the requirements for LAP-BAND® surgery to patients with a BMI over 30 and weight-related health problems.

How long does the recovery time for gastric bypass surgery take?

Most gastric bypass patients are able to resume their daily activities in 6-8 weeks. However, the length of recovery time for laparoscopic gastric bypass surgery depends significantly on your overall health and your body’s ability to heal. Dr. Dahiya uses the latest in laparoscopic surgery techniques to make bariatric surgery less invasive, which helps to reduce the recovery time for gastric bypass surgery. Nonetheless, you should plan on having at least two months before vigorous activity and on following post-surgery dietary restrictions on solid foods.

What are the differences between LAP-BAND® surgery and gastric bypass surgery?

LAP-BAND® surgery and gastric bypass surgery use different methods, but both are designed to reduce food intake and encourage weight loss. LAP-BAND® surgery uses a gastric band, which cinches around the stomach to create a small section that fills up quickly and empties slowly. This is how LAP-BAND® surgery works to help you feel full faster and eat less.

In laparoscopic gastric bypass surgery, on the other hand, Dr. Dahiya seals off a small pouch of your stomach, then connects it directly to your small intestine via an opening called a stoma. Dr. Dahiya uses an innovative technique for Roux-en-Y gastric bypass surgerythat is actually named for him, the Dahiya Vertical Micropouch™. In your bariatric surgery consultation, Dr. Dahiya can explain in detail exactly how gastric bypass surgery works.

What lifestyle changes are needed after gastric bypass surgery?

Laparoscopic gastric bypass surgery helps you feel full after eating smaller portions, which can help you lose weight. However, you must also be committed to a healthy diet and plenty of exercise if you want to be successful in reaching your goal weight and staying there. Dr. Dahiya and our nutrition specialist Dr. Jose Mari-Elacion will help you stick to your post-surgery weight loss program with monthly follow-up sessions for a year after your surgery.
