Importance of protein supplementation after bariatric surgery

4 November, 2019

In the Mexico Bariatric Center in the network of Health & Wellness Bazaar, we take care to provide adequate follow-up in each of our patients, to obtain the expected results after surgery performed weight loss. As you know, bariatric surgeries are currently the best option for treating morbid obesity, however, the rapid weight loss that occurs after completion is accompanied by a considerable loss of muscle mass. It is important to control this through supplementation since failure to do, you may a nice little aesthetic for patients is obtained.


But food after suffering a considerable reduction procedure. In some weight loss surgery in Mexico, there is a major deficiency of macronutrients, mainly proteins, either by ingestion or by absorption lower. Importantly, the protein requirement in the immediate postoperative period becomes indispensable, since at this stage increased catabolism (the process in which muscle for energy production is degraded) occurs. Unfortunately, many patients do not prioritize proteins in their meals, either as difficulty chewing (especially meat) or satiety produced by this macronutrient.


With an increase in demand of the body and very low consumption, inadequate protein can cause several problems, such as excessive loss of lean mass, severe hair loss, reduced immune system, and weakened nails. Note that the vegetable proteins have a lower amount of nitrogen, compared with the animal, therefore, who think to choose a vegan diet should consider how necessary protein supplementation during the postoperative.


According to the most current recommendations for patients operated in Mexico Bariatric Center, Protein intake should be 60 to 120 g per day, prioritization of proteins of high biological value (complete proteins that have all the essential amino acids in ideal proportions and amounts) to meet organizational needs being indispensable. Able to achieve such recommended amounts requires the use of protein supplements because the quantities ingested only through meals are very low, especially in the first six months after surgery.


There are indeed several options for protein supplements on the market, but what to buy ?, What is the best? developing strategies that target protein complementation with preparations of high nutritional value, which are easily digestible and good acceptability by patients is recommended. Among the options available on the market, the most important are: whey protein, casein, albumin, soy protein isolate, and pea protein or rice (presented as vegan options).


Now, the first thing you need to evaluate is the cost-benefit ratio. It does not help to choose the most expensive on the market if the patient simply can not buy a supplement. Another important factor is the taste, because of the current difficulties to consume protein supplement indicated is nausea, which can even develop an aversion to the protein. The nutritionist who must necessarily accompany postoperative patients should always offer alternatives and different ways of preparing for easy use of the supplement.

Concerning whey protein, compared with other supplements, it is to have the best absorption and promoting increased satiety. It has a higher content of branched-chain amino acids (important in preventing degradation of muscle tissue) and does not contain lactose. Some studies also indicate that consumption of whey has a stimulating effect on the immune system, something that certainly worth considering.


The use of “Whey” is based on the property of whey proteins, which do not undergo conformational changes by stomach acids. Upon reaching the small intestine, they are rapidly digested and absorbed amino acids, quickly raising the concentration of plasma amino acids and stimulating protein synthesis in tissues. Another important aspect to consider is the type of serum to be prescribed. The isolated whey protein is purer and concentrated, containing 90% or more protein and little or no lactose and fat.


The concentrated whey protein is between 29% and 89% protein, according to the manufacturer also decreases as the protein concentration increases the fat and / or lactose. The hydrolyzed whey protein has more chains broken proteins in peptides,

Another important when considering protein supplementation fact, besides the most critical period after surgery in our Mexico Bariatric Center, It is supplementation of patients undergoing programs to gain muscle mass physical activities. The metabolic basis for the increase in mass in skeletal muscle is the balance between protein synthesis and physical exercise resistance resulting in metabolic gain and muscle growth. The availability of dietary amino acids is critical in this process so that the food supplement that provides this supply of amino acids to promote muscle mass gain is necessary.


Ingestion of the training period of isolated serum fractions results in increased muscle synthesis; therefore, its use is also recommended for this purpose.

We hope this post has been helpful. Should one wish done gastric bypass Mexico or other bariatric procedures under the supervision of experts and have adequate nutritional monitoring for preserving muscle mass during weight loss, do not hesitate to contact the specialists that make up the network of Health & Wellness Bazaar.
