I have had problems with my digestion since I was a kid. Now (at 26) it has definitely gotten worse. Since July of this year my stomach has been making extremely loud noises (grumbling, popping, I can hear and feel the bowel traveling through my intestines). The noises are so loud that I have left classes early and even missed classes due to this. I have been having alterations between constipation and diarrhea. One day I can go, the next I can't. Stomach cramping, gas and bloating have accompanied these symptoms as well as sudden weight gain. The weight gain really perplexed me because I had just begun a workout regimen and my eating habits had not changed one bit. I went to the doc and I had every test done. Cat scan, blood work to check for Celiac Disease, X-Rays, etc. I have taken Miralax, Dulcolax, fiber supplements, you name it. Nothing has helped and all of the tests came back saying that I am fine except for backed up stool which has now diminished. My alkaline phosphate level has been elevated for a year. The blood work also showed that my vitamin d level is 13 when it should be between 33 and 100 and my thyroid is slightly elevated. I also get frequent headaches and I have been feeling extremely fatigued. My doctors are stumped I believe, and they seem to be downplaying my symptoms, meanwhile I am suffering over here and missing too many classes! This weekend something clicked in my head and I thought about the pattern of my eating habits and how they trigger my symptoms. Gluten came to mind. Firstly, I am vegan so I do not consume dairy or meat products. I do eat a lot of meat substitutes, most of which contain gluten. So I eliminated all of the gluten from my diet for 3 days and my stomach did not make one sound over the course of those 3 days. From there I decided to do some research and I found a lot of info on how gluten intolerance can present a lot of the symptoms that I have. I went to my doc and she completely dismissed the idea that I may be gluten intolerant. But I swear, when I eliminated the gluten my stomach completely calmed down. She said that since I had the test for Celiac it's unlikely that I have gluten intolerance since they are the same thing. I actually thought that they were different...Now I am kind of confused. I am so frustrated because I felt like I had a breakthrough since it seemed that gluten was the culprit to my stomach woes. I still do believe that there is some kind of link there. Would anyone know if a person can be gluten intolerant without having Celiac Disease? Could it be that I have IBS and the gluten is triggering it? And what about my vitamin d deficiency, thyroid and alk phos? Can't gluten intolerance cause deficiencies in nutrition? And I've read that gluten intolerance also causes irritability and anxiety, both of which I have been struggling (anxiety is a big problem) with as I have not even been able to keep my thoughts straight (forgetting things, memory problems, doing horribly on tests even though I know the material.) I am wondering why my doctor said that gluten intolerance and celiac disease are the same thing? I thought Celiac caused damage to your stomach while gluten intolerance did not. I would appreciate any insight on this. I am at my wits' end. Thanks!
