I am really getting stressed starting college. I have a very important exam and have a colonoscopy scheduled in a month but it the test is before when I can even see anyone. I am also seeing an endocrinogist as well. I have hypothyroidism and leaky gut where my gut is too permeable and substances leaky into my blood stream. I also have low LH, low testosterone, never feel hungry and never feel full. II eat a lot of high fiber foods and poop very little. I'm wondering if anyone has heard of leaky brain where your BBB is permeable to substances especially lectins. Otherwise, I am thinking it could be a fungus. My roof of my mouth is yellow. My doctor said this is billirubin. I feel better taking candex. Otherwise, I'm in a constant state of brain fog the whole day usually. I got a tongue swab and there was a small amount of acremonion fungus on it. My tongue usually has a yellow residue on it. Any advice for me?
