6/13/18 was my gastric bypass surgery. Today is day 1 starting protein shakes. I'm an avid Premium Protein user with no issues pre.op. my first few sips burns my stomach and immediately crampy. Does anyone have this issue or any suggestions?! I don't have any problems with sipping on water. Possibly any suggestions for alternative protein supplements? Maybe I'm lactose intolerant now. I need any suggestions and are much appreciated. THANK YOU!!

How about Protein Water, like ProteinH20? Or Fairlife milk?

@darlingla Try a higher quality protein, making sure it's listed as a whey isolate, to avoid the lactose.

You could also try the plant based proteins to see if that helps you out any.

Isopure Zero CARB RTD, drinks are "ready to drink", clear, high quality proteins. The taste can throw some folks off, but the high protein count, low calorie count and 20oz of liquids, it does appeal to a lot of folks.

According to the internet, the Premium Protein label says "Contains Milk" in the form of Milk Protein Concentrate, according to the ingredients list. I guess that would qualify it as low-lactose, but not lactose free.

Many experience problems drinking protein shakes. I hated them. But in the beginning I drank them, three 16-ounce protein shakes a day, in order to meet my protein requirements. You do not have to like protein shakes only tolerate them. There are many varieties of protein shakes available today. Experiment until you can find one you can tolerate.

I used Muscle Milk Light (Vanilla Creme) powder blended with water and a half a banana. That worked for me. But on the opposite end of the spectrum, you might try premixed Isopure.

Without sufficient protein, your body will scavenge protein from other areas of your body, such as your muscles. Protein is extremely important after surgery as its job in the body is to build and maintain tissues including your body's major organs and skeletal muscles. Protein deficiency, when continued over a long period of time can cause a disease known as protein caloric malnutrition. Common symptoms are poor healing, fatigue, hair loss and muscle wasting. Immediate post op, protein promotes healing of the staple line and incisions.

Also generally in the hospital you were given antibiotics to kill any bad bacteria and prevent wound infection. Antibiotics not only kill the bad bacteria but also the good bacteria in you gut. So after you go off the antibiotics, it is good to restore the good gut bacteria. This can be done by taking probiotics.

Thanks for the help everyone!
