I didn't. But the there was one person on TV that casually made a comment about his unexpected weight lost and that he did visit a doctor and that's what it was. For me the explanation hit so close home that I immediately audited all I ate and drank and took action. Then that left me with gastritis which made me feel about the same and only slightly better. I search fir gastritis diets and followed that about 6 days. I also took an antiacid when I felt bad. After that I realized that I need to eat more food, because I was a little more active but didn't have enough energy. I learned to avoid the food that made me sick and I needed to unlearn this: carbs, beans, meat, milk. If you become sick enough, all food feels like poison. Then I realized I was missing probably all the vitamins, that's what it means you don't absorb the food. I felt good after some multivitamins, some magnesium and really good after Vit. C: higher appetite, less muscle and tendons pain, more energy. Now I'm at the point when I can go to the gym again and not feel like I need to sleep right now after 3 squats.
