Over a course of close to year my body began to break down, I had my first sinus infection. I was light headed dizzy , but no stuffiness or pressure odd. Then the first time in my life I had Edema on lower back.. Sibo can cause Edema. I felt my heart racing and shortness of breath, I also noticed frequentcy of urnination. I hired several MD to figure it out. One of them asked me if I ever had an eating disorder because of my weight drop! For heaven's sake when you have dry heaves and feel like you have the stomach flu day after day it is hard to eat. I was diagnosed in one visit by an Nautropathic doctor then I took the breath test the next day and it was positive for hydrogen SIBO Thank God finally someone figures it out. Rifaximin works!!
