Gastric Bypass Surgery

What is Gastric Bypass Surgery?

Gastric Bypass Surgery includes gastric bypass surgery. It is also known in French as "Roux-en-Y." During gastric bypass surgery, your doctor alters how your stomach and small intestine absorb and digest food.

Gastric bypass helps in weight loss by:

• Limiting the amount of food that your stomach can hold
• Limiting the number of calories and minerals absorbed by your body
• Changing your gut hormones, which help you feel fuller for extended periods, can help with appetite suppression and reversing obesity-related metabolic syndrome.

What is Roux-en-Y Gastric Bypass Surgery?

The Roux-en-Y gastric bypass is regarded as the 'gold standard' of weight loss surgery. It is the most common bariatric operation performed worldwide. Your surgeon will do the following during Roux-en-Y gastric bypass surgery:

• Divide the top of the stomach from the remainder to create a tiny stomach pouch roughly the size of an egg.
• The small intestine is then divided, and the bottom end of the divided small intestine is raised and attached to the newly formed small stomach pouch.
• Finally, the top piece of the divided small intestine is joined to the small intestine further down, allowing stomach acids and digestive enzymes from the bypassed stomach and the initial portion of your small intestine to combine with the food.

What are some of the issues that mini gastric bypass can help manage or improve?

If you have medically significant obesity, simply decreasing weight can improve your health significantly. However, gastric bypass surgery accomplishes much more. It alters your metabolic system over time to help you regulate your blood sugar, blood pressure, and hunger.

Gastric bypass surgery can help with the following conditions:

• Hyperglycemia.
• Hyperlipidemia.
• Hypertension.
• Cardiovascular illness.
• Diabetes.
• The disease of the fatty liver.
• Gastroesophageal reflux disease.
• Sleep Apnea
• Osteoarthrosis.

Who is bariatric surgery for?

In general, gastric bypass and other weight-loss operations may be an option for you if you meet the following criteria:

• You have a BMI of 40 or greater (severe obesity).
• You have a BMI of 35 to 39.9 (obesity) and a severe weight-related health issue, such as type 2 diabetes, high blood pressure, or severe sleep apnea. If your BMI is 30 to 34 and you have substantial weight-related health concerns, you may be eligible for some forms of weight-loss surgery.

However, gastric bypass is not appropriate for everyone who is significantly overweight. You may need to meet specific medical criteria to be eligible for weight-loss surgery. You will likely undergo a thorough screening process to determine your eligibility.

Risks and complications

Gastric bypass and other weight-loss operations, like any major surgery, carry possible health concerns, both short and long-term.

The risks of the surgical procedure are similar to those of any abdominal surgery and can include:

• Excessive bruising
• Infection
• Adverse effects of anesthesia
• Clots in the blood
• Problems with the lungs or breathing
• Leaks in your digestive system

Gastric bypass can have the following long-term risks and complications:

• Obstruction of the bowel
• Dumping syndrome, which causes diarrhea, nausea, and vomiting
• Gallstones
• Hernias
• Hypoglycemia is a state of low blood sugar.
• Malnutrition
• Perforation of the stomach
• Ulcers
• Vomiting

Complications of gastric bypass can be lethal in rare cases.

How to prepare for Gastric Bypass surgery?

You may be required to begin a physical exercise program and refrain from smoking in the weeks preceding your surgery.

You may be restricted in what you eat and drink and which drugs you can take before surgery.

What to expect?

During the procedure:

Your surgery will begin with general anesthesia. Anesthesia keeps you asleep and comfortable during the operation.

Your gastric bypass depends on your situation and doctor's practices. Some abdominal operations use massive open wounds. Most laparoscopic procedures require inserting equipment through many tiny abdominal incisions. After performing open or laparoscopic incisions, the surgeon cuts across the top of your stomach to close it off. The walnut-sized pouch holds around an ounce of food. The average stomach can store 3 quarts of food. Sewing part of the small intestine directly into the pouch, the surgeon cuts it. The food enters this little stomach pouch and then the attached small intestine. Food immediately reaches the middle of your small intestine, bypassing much of your stomach and the first segment. Surgery usually takes many hours. After surgery, you wake up in a recovery room where doctors watch for complications.

After the procedure

After gastric bypass surgery, you can drink but not eat while your stomach and intestines heal. You'll then follow a particular diet that gradually introduces purees. After that, you can eat soft foods until your body can handle stiffer ones.

You may have many food and drink limitations. After surgery, your doctor will prescribe a multivitamin with iron, calcium, and vitamin B-12. You'll have regular medical exams after weight-loss surgery in the first few months. Lab tests, bloodwork, and examinations may be needed.

Your body may change due to rapid weight loss in the first three to six months after gastric bypass, including:

• Body aches
• Tiredness
• Feeling cold
• Dry skin
• Hair loss and thinning
• Changes in mood

Results

Gastric bypass provides long-term weight loss. Weight loss depends on surgery type and lifestyle changes. It may be able to shed 70% or more of your weight in two years.

Gastric bypass may treat or resolve overweight-related conditions, including:

• Gastroesophageal reflux disease
• Heart disease
• High blood pressure
• High Cholesterol
• Obstructive sleep apnea
• Type-2 diabetes
• Stroke
• Infertility

Gastric bypass may improve your quality of life by improving your everyday routine.
