24yo male with undiagnosed chronic stomach issues

So i have been dealing with chronic diarrhea now for probably 5 years give or take and i am fed up with dealing with it. I am a very active 24 year old male with no other health problems and not taking any medication. The only medication that i have ever taken for an extended period of time is minocycline for acne back in high school.

On a good day my stool is a 6 on the bristol chart in various stages. Sometimes it will be a couple whole pieces that are fluffy and flakey and generally light brown in color with stringy fiber looking things and usually food chunks, other times it is just a big pile of the fluffy type pieces along with the other stuff.

What is prompting me to reach out this message board is that it has gotten a lot worse in the last week or so. I am constantly having type 7 stool with little food chunks in it. I think i am having type 7 because of my inability to eat. I just cant eat anything because my stomach is upset. When i do eat, i eat because i know i need to not because i want to. I also have lost probably 10-15 lbs in the last week. I am 6' 170 when i am "normal" and i dont have any weight to lose, so losing 10-15 lbs in the last week has taken a big toll on me energy and health wise. I just feel that constant churning in my stomach that is normally accompanied with diarrhea in "healthy people", i feel run down and tired, my joints ache (my friends have called me an old man for years because of it), and i just generally dont feel good. For example today is a perfect day outside and I would love to be out enjoying the 80 degree temps and clear blue skys but i just dont have the energy or desire to because of my stomach.

I cant seem to cut out anything from my diet to help make it any better. I have tried everything from removing gluten, yeast, dairy and all processed foods. I generally eat a very healthy diet consisting of fruits and veggies rice and meats. Right now i am down to vegetable soup, fruit, crackers, apple sauce, and almond butter. But it still seams to make little difference.

Stress seems to make it worse, but the only food that i can say for certain that makes my problem worse is alcohol, even just one beer.

Im just fed up feeling like this and will do anything to feel better. Any help would be appreciated.

Have you been to a gastroenterologist? Sounds to me they need to do a colonoscopy to see if there is anything going on in your intestines.

If the SCD does help, I would definitely try saccharomyces boulardii - it eats carbs and can help "crowd out" the bad bacteria (or whatever) that you are trying to avoid feeding by being on the SCD. Now that I've been taking it for a while, I can tolerate some cheating on the diet.

Want me at er for ct scan ... very frustrated
