After Gastric Bypass surgery, it is possible for a patient who has undergone surgery to lose weight between 120 kg and 50-60 kg. Weight loss after gastric bypass depends on the patient’s adaptation process along with the success of the operation. The first two months after gastric bypass lose weight very quickly.
The patient will continue to lose weight for a long time. Loss of appetite will also continue. But a condition such as weight gain can also be experienced, albeit a little.
Patients who eat too many carbohydrates and unhealthy can gain weight again. Patients battling obesity could lose 50 or 60 pounds in two years thanks to gastric bypass surgery.
The first choice in weight loss methods is always non-surgical methods. Lifestyle changes, diets and sports exercises are also the backbone of these non-surgical methods.
In cases where these methods do not work, you can switch to semi-surgical, semi-non-surgical methods such as a stomach balloon, or the direct surgical method can be put on the table. There are several types of surgical interventions that can be applied to lose weight.
Gastric bypass is also one of them. The main goal is to lose weight by changing the anatomical structure of the stomach and small intestine. So, yes, gastric bypass surgery is weight loss surgery. But this operation is not applied directly to every person who wants to lose weight.
A person must provide certain conditions. Especially if the body mass index is between thirty-five and forty; as if there is no other accompanying disease. Some physical conditions also determine whether the operation can be performed.

Weight loss after gastric bypass
Hormonal changes that occur after surgery are also effective in weight loss. A significant increase in Glucagon-Like Peptide-1 (GLP-1) and Peptide YY (PYY) levels, while a decrease in Leptin and Ghrelin levels are observed. As a result of these changes, the patient’s appetite and feeling of hunger decrease.
Immediately after the surgery, before weight loss begins, the blood glucose levels of the patients decrease and their insulin requirements decrease. Weight loss after gastric bypass occurs gradually.
The procedure has two components. While performing gastric bypass surgery, first the upper part of the stomach is divided from the rest of the stomach to form a small gastric pouch with a volume of approximately 30 milliliters.
Then the first part of the small intestine is divided and the lower end of the divided small intestine is lifted up and connected to the newly formed small stomach sac.
This process is done by connecting the upper part of the divided small intestine down to the small intestine, so that the gastric acid and digestive enzymes from the bypassed stomach and the first part of the small intestine are finally mixed with food.
Gastric bypass works by several mechanisms. First, similar to most bariatric procedures, the newly formed gastric sac is significantly smaller and can hold fewer meals, resulting in fewer calories being consumed.
Additionally, calories and nutrients are likely to be absorbed to some extent less, as there is less food digestion by the smaller stomach pouch, and a part of the small intestine that normally absorbs calories and nutrients through which food no longer passes.
Most importantly, redirecting the flow of food in the body produces changes in gut hormones that increase satiety, suppress hunger, and reverse the primary mechanisms of obesity that trigger type 2 diabetes.
Why does weight loss stall after gastric bypass?
The first reason why you should not lose weight after Gastric Bypass surgery is that the patient should not be given proper dietary information after surgery, or the patient does not have the discipline to follow the diet after surgery. Protein is absolutely crucial for losing weight and staying healthy.
There are several reasons why protein intake affects weight loss. Be sure to eat 60-90 grams of protein a day. Eating too little can be just as harmful in losing weight as eating too much. Be sure to eat protein first and stick to the diet after surgery. If you do not drink enough water, your body will become dehydrated.
When dehydrated, your body cannot cleanse itself of toxins or regulate itself to its full capacity. Water is depleted from your body very quickly, so it is important to drink water throughout the day. Without proper nutrition, unhealthy calories can lead to many problems caused by malnutrition after surgery.
Can You Put All Your Weight Back on After a Gastric Bypass?
A gastric bypass can be effective in helping you lose weight, but it is not without its risks. Some patients experience a significant weight regain after the surgery. This is most likely to happen to those with binge eating disorders, who do not adhere to healthy eating habits or are not physically active.
Other risks associated with gastric bypass surgery include drug and alcohol abuse. Some people have no health conditions that make them high risk for regaining excess weight after the procedure.
A healthy diet after the surgery is vital to avoiding weight gain. In the early months, your portion sizes will increase as your body adapts to the smaller stomach. Your surgeon will provide you with instructions on how to maintain this new eating pattern.
Your doctor will likely provide you with nutritional advice on which foods to include in your diet. A diet rich in fruits and vegetables, lean protein, and plenty of healthy carbohydrates is essential.
After gastric bypass surgery, the pylorus is preserved, but the pouch will no longer be connected to the small intestine. In addition, the new connection between the pouch and the small intestine will widen over time.
This dilation can result in increased weight regain. The good news is that this can be repaired by undergoing revisional surgery. The surgeon will then make the pouch tighter and increase the size of the small bowel bypassed.
