Frequently Asked Questions


Fasting is permissible, but under the supervision of specialized doctors.

Yes, and it is the best whether considered as a fundamental process or as a first stage of the path conversion process, according to the results in weight loss after several years.

-Obesity cases associated with hiatal hernia and gastroesophageal refluxCases of addiction to chocolate and sweetsRevision surgeries due to weight regain or complicationsPatients with diabetes and metabolic disorders prefer undergoing bypass surgeries

Path conversion is the most important process among obesity procedures.It is the almost only option in some cases such as:Obesity accompanied by gastric sagging with or without diaphragmatic hernia.Obesity accompanied by type 2 diabetes and other metabolic diseases.Cases of specific operations for size adjustment only (failed sleeve, stomach band, stomach folding) for patients addicted to sweets (chocolate, ice cream, etc.).Other patients can choose between sleeve gastrectomy and path conversion.Path conversion is characterized by the following:Greater long-term effectiveness in terms of weight maintenance after the operation.Greater effectiveness in controlling sugar and metabolic diseases.More comfortable meal intake in terms of type and quantity after the conversion operation.Performed without removing anything from the body.Why does path conversion have a bad reputation among patients?It requires high expertise to be performed correctly, and those who do not have this expertise try to scare patients and guide them towards the sleeve operation because it is theoretically easier.Dr. Nidal Abido discusses with patients the appropriate type of operation before the procedure, as well as the advantages and problems of each operation, before making a decision on the type of operation.Please do not hesitate to ask any questions about obesity operations as you can provide us with your weight, height, and age, and we will help you choose the most appropriate solution.

What is the amount extracted from the stomach in a gastric sleeve or gastric bypass surgery? Does the amount extracted from the stomach affect the amount of weight loss? This question has always worried the patients and is asked to us before and after the surgery. Answer: The size of the extracted portion of the stomach is not important and has no relation to the amount of weight loss. The experience and precision lie in the size of the remaining stomach within the body, which is measured using a tube inserted into the stomach through the mouth. It accurately determines the amount of stomach that should be preserved and extracts the rest. The extracted portion may be 70-75-80% of the stomach's size, but it is not important. What matters is that the remaining portion of the stomach is appropriate and regular like a tube and not twisted. If the remaining portion is narrow or irregular, it may lead to repeated vomiting that may only end with another corrective surgery. In case the remaining portion is wide, this leads to a quick rebound in weight gain and the failure of the procedure. The surgeon's experience and skill lie in manufacturing the appropriate stomach in terms of size and shape. Feel free to contact us for assistance in living a better life with obesity surgery.

At what weight should we consult an obesity surgeon? When reaching a noticeable weight gain, we need to calculate what is called Body Mass Index (BMI)It can be calculated by pressing on the label in our position called Are you overweight BMIIf it is between 30 and 35We need to consult a nutritionist to adjust our diet and it may help to undergo some temporary simple procedures like stomach balloon in its various typesWhen this index reaches 35which is equivalent to a weight of 90 kilograms for a person whose height is 160 centimetersWe must seriously consider a solution to this problem, either by following a balanced diet or seeking consultations with an obesity surgeonWhen this index reaches 40which is equivalent to a weight of 100 kilograms for a person whose height is 160 centimetersThe matter has entered the stage of morbid obesity, which is a cause of a range of diseases, mainly joint problems, diabetes, hypertension, breathing problems, and heart problems...In this stage, if diet therapies fail, we should consider obesity surgeries like stomach sleeve or gastric bypassWe do not recommend waiting until reaching higher weights for the following reasonsThe higher the weight, the more difficult the operation becomes and the higher the risksThe higher the weight, the lower the expected cosmetic results of the operation and the more loose skin sagging, which may require subsequent repair

The size of the stomach after a successful gastric sleeve surgery is approximately 50 milliliters. After two or three years, the stomach can expand slightly to hold around 100 milliliters, which is normal and adjusts to accommodate the body's needs after weight loss. Stomach expansion to 300 or 400 milliliters after years of gastric sleeve surgery is considered abnormal and can lead to weight regain. The reasons for this include not adhering to good dietary habits and not getting rid of bad habits after obesity surgery, the most important of which is constantly drinking carbonated water, which leads to stomach expansion. Not stopping eating when full and continuing to eat until feeling overly full or vomiting will eventually result in unnatural stomach expansion, nullifying the effects of gastric sleeve surgery and causing weight regain. This applies to gastric bypass surgery and other obesity surgeries as well. Early stomach expansion after the surgery may be due to the wrong choice of an experienced doctor.

The difference between obesity surgery and cosmetic surgery.Obesity surgeries aim to reduce excess weight and get rid of obesity-related diseases, or prevent their emergence.On the other hand, cosmetic surgeries aim to fix external body flaws and have no relation at all to weight loss.For more information, you can watch the video.

Digestive Problems after Bariatric SurgeryBariatric surgeries can cause some digestive problems such as diarrhea or constipation, as well as gas and foul odor of gas and stool.We observe these problems more after the gastric bypass procedure than after gastric sleeve surgery.The reason is that the digestive process after the gastric bypass surgery is not complete, as it occurs in the second and third parts of the intestines. This causes a decrease in the absorption of some nutrients and also leads to poor digestion of food, where intestinal bacteria take advantage of this situation and feed on undigested food, causing fermentation and these mentioned digestive problems such as diarrhea or constipation, gas, and foul-smelling stool.These problems are less frequent in the case of sleeve gastrectomy or gastric reduction due to the absence of absorption issues.Suggested solutions:These problems may persist for weeks to several months after the surgery.You can alleviate their effects by taking dietary supplements.Avoid sugars, especially white sugar, fructose, and starches, except for rice if soaked in hot water for half an hour before cooking.Avoid consuming certain fruits that contain sorbitol, such as pears, peaches, and plums, or consume them before the meal, not after it.Avoid consuming anything (water, fruits, sweets) for two hours after a meal to allow the body to digest peacefully.In some cases, we may need to follow up with a nutritionist who can guide us with some tips or medications to help alleviate these problems.
