I've been trying to understand why I am having problems running these days, amongst other abdominal discomforts and stumbled across the idea that Biotin deficiency can lead to muscle cramping and muscle failure, amongst other things. Biotin supposedly is produced/absorbed in the large intestine. But I don't have that for 30 years. I had just learned that the Ileum, which is totally impaired when turned into the J-Pouch is where B12 is absorbed and that the colon is also responsible for the absorption of Potassium, the lack there of can cause problems with the kidneys and blood pressure; now, in response to slight abdominal pain over the past few weeks, especially in the region of the Gallbladder and the region of the left kidney, I visited with a Gastroenterologist who gave me a prescription for B12 injection, and for relaxing the small intestine (to remove abdominal discomfort, which has not change anything) and who sent me to a cardiologist for Hypertension... With the B12 injection, I feel the seem; no increased energy... Infact, my running has become horrendous, with burning in my legs halfway into the run... I find myself running in circles on the internet seemingly finding connections between colectomies and J-Pouches and problems with glucose metabolism and fat metabolism and shortages in electrolytes and all of this may cause problems with other parts of the body. I read that Biotin suppliments help with the Biotin deficiency. However, if Biotin is only absorbed in the large intestine, what use would that be for me? However, between the possible shortage of biotin and of potassium, I think I may have found some reasons for my discomforts. As for the Biotin deficiency; first signs are thinning of and loss of hair. What I've noticed over the past week or so is a rapid graying of my hair... I'm 43-years-old. If anyone knows of the true information about these deficiencies, I would appreciate hearing. Ross
