Post-Gastrectomy Dietary Guidelines from Protica Nutritional
The choice to get gastric bypass surgery is the first in a sequence of events. The initial stage in preparing for surgery is to determine whether there are any nutritional shortages. It is important to address vitamin and mineral deficiencies before to the surgery because they are common in obese people. Both the stomach's volume and the amount of time food spends in the intestines are targets of the operation. Large meals or digestion cannot be facilitated by the stomach after surgery. This alone reduces the amount of food consumed. Because food goes straight through the digestive tract, it doesn't have much time to react with the enzymes produced by the pancreas and the liver. Nutrition absorbed from food decreases significantly because of this. Nowadays, the majority of gastric bypass procedures only permit normal intestinal function during the first fifty centimeters. This is in stark contrast to the seven feet of small and large intestine required for food absorption prior to operation.
The postoperative period can be rather challenging because to the significant decrease in the ability to absorb food. Until your digestive system heals, it's best to stick to clear water for the first two days. A normal diet can be resumed when the gut is retrained for approximately two months. It is important to remember the restrictions put on you by the gastric bypass operation while you are healing. The stomach can now only hold about eight ounces due to the reduction in size that occurred during surgery. In addition, the stomach can no longer grind food into small enough pieces to start the digesting process. That being said, a liquid to soft solid diet that can be consumed in tiny portions six to eight times daily would be the most suitable for postoperative recuperation. Fluids rich in nutrients are ideal since they hydrate and fuel the body simultaneously. Staying away from or limiting non-nutritional drinks to times in between meals is recommended.
Careful thought should also go into the nutritional kind. Making sure you have enough energy to recover from surgery without affecting stomach emptying time is the goal of choosing the right macronutrient. Carbohydrates and lipids are on opposite ends of the appropriate spectrum when it comes to this. Carbohydrates cause unpleasant side effects such gas, bloating, diarrhea, and excessive perspiration, and they travel through the body rapidly. Because of its strong correlation with obesity, fat is frequently disregarded despite the fact that it significantly slows the intestines. According to the research, proteins are the macronutrients that are recommended following gastric bypass surgery. The stomach transit time is unaffected by proteins. Additionally, following a bariatric bypass or other significant surgical operation, a high-protein diet can supply the necessary amino acids for healing and development.
In addition to these benefits, a high-protein diet is particularly useful in combating obesity. The goal of gastric bypass surgery is to prevent weight gain by limiting caloric intake. In addition to burning calories, burning stored fat is essential for reaching a healthy weight. Burning stored fat and lowering body mass index (BMI) both necessitate an increase in energy expenditure, or basal metabolic rate. Because dietary proteins enhance baseline metabolic rate via promoting protein synthesis, a high-protein diet can help accomplish this. Postoperative observations corroborate this idea as well. Weight reduction, even with restricted consumption, typically stops without a high-protein diet.
The current recommendation for protein consumption in the post-operative period is 90 grams per day. It can be challenging to maintain such a high protein intake after a gastric bypass surgery due to the damage and restrictions experienced by the digestive system. Conventional diets and food sources of protein and energy are frequently not absorbed because the digestive system is not yet ready. Consequently, the best post-operative diet consists of a sugar-free, highly bioavailable fluid protein concentrate with sufficient amounts of vital amino acids, vitamins, and minerals. Protein concentrates that have been hydrolyzed or pre-digested make digestion even easier. Even at low doses, this nutritional fluid can provide concentrated energy and hydration.
A high-protein concentrate can be useful as a supplement in the times between meals even after you've recovered and are back to your regular eating schedule of three or four square meals. If you want to lose weight and keep it off, you need a protein supplement that keeps the thermogenic activity going. In addition to keeping you nourished on bad days—which are typical in the months and years following a major surgery—it makes up for any amino acid deficiencies in your diet.
