My gastro doctor found that my pancreas was not functioning properly. I was nauseous and losing weight. As she explained, the food I was eating was literally passing through my digestive track or sitting there rotting. I was not getting any nutrients from the food I was eating, thus, weight loss and loose stools. She prescribed EnteraGam, VSL 3 probiotics. Plus I take Pertzye Capsules with every meal and snack( as my pancreas was not providing the enzymes my body needed to help digest the food and maintain the nutrients I needed from the food). I have been taking them a month and this is helping me to regain strength, not as nauseated and for the first time in a year.....I had not lost weight....had not gained any but she says that will come as my body adjusts. My PCP totally missed the dx of the non functioning pancreas. Hope this helps someone.
