I have chronic shallow breathing and I also have low blood pressure. I hate the shallow breathing because it can be a bigger pain than most people imagine. I have problems all day long today and that is not something new. I have this problem even when I am talking to someone. I was told by the nurse in school that I have asthma. But the doctor told me that he won't be able to check if I don't have any attack. This means that I can't get it checked till I induce an attack on me. But I wonder if there are no other ways to check for the presence of asthma. I also have allergic reactions towards pollution and pollen in the air. My father calls this hay fever. I don't have a lot of wheezing but I cough all the time. I wanted to know whether asthma can cause other complications like hypoglycemia, oral thrush etc. I hope that somebody will be able to help me out with the problem.
