I do have chronic bloating though, only when I fast do I have no bloating, and my stools are very hard. I have joint pain and muscle aches everywhere, i have yeast infections in my groin and I cannot tolerate sugar at all. Maybe the anemia is caused by SIBO or SIFO messing up my intrinsic factor in my gut, therefore making me b12 anemiIt took me some time to read your lab results from october because I dont know what language it was in. But your MCV was low and your RBC count was elevated. RBC count elevates due to low oxygen levels to compensate. Low MCV is usually iron deficiency anemia which explains all your symptoms. Low iron will also compromise energy production. You probably need iron. This is why you are severely intolerant to exercise and even have breathlessness being sedentary working at a computer. Low iron will lead to poor oxygenation and low ATP. Its not a gut issue, you need iron.
