I had suffered from IBS-C in highschool for a few years but it went away after I started a low-carb diet for a month and graduated. I'm unaware if it was the lack of stress due to graduating or the low carb diet, but I was able to eat whatever I wanted, and whenever I wanted for the past 3 years with no problems at all. I went on a service trip with my college this past april, and on the last day we were there I had a horrible bout of Diarrhea, which was possibly caused by my period. I had to hold it for a good hour because we were in a meeting that I was not allowed to leave. The gas and pain that morning were so unbearable that I was sweating and my eyes were tearing. I was finally able to get to a bathroom after an hour and after I went, I was ok the rest of the day. However, ever since that day, I have had extreme gas and diarrhea with everything I eat. I had to drop out of my last quarter of school of my junior year because I couldn't even sit in a quiet classroom with having loud gas pains and running to the bathroom. It has gotten progressively worse and it is to the point where I can barely eat anything. The only thing I can keep in me with getting gas and pains is yogurt, but even then I get a little gas and d. I barely leave my house anymore. I used to be a social butterfly and constantly working or volunteering, but I can't even make an eye appointment because I know I'll sit there embarrased with loud gas and pain. It starts as soon as I get up in the morning and never subsides. I've lost 15lbs and I can't lose anymore since I'm only 5'1 and at 100lbs. I keep getting the IBS-D diagnosis but I don't know if thats it. What can cause extreme (emphasis on extreme) gas like this? The only thing I've found is leaky gut syndrome. Could it be possible I got a parasite while on the service trip? Could I have damaged my digestive system or intestines by holding it in that morning? I need any help you can give me. I just want my old life back.
