I have had NAFLD for over 5 years, but, following a fibro scan ,was recently diagnosed with cirrhosis. I have noticed over the last year that I get breathless si8tting down, even though I can walk long distances and am increasing my cardio-vascular stamina at the gym. Also I recently fainted and feel faint at time, usually when I stand up suddenly. I do not have ascites. Is this common? What might be causing it?
