When it comes to asthma and appetite, doctors and dietitians worry most about patients who eat too much, shun exercise for fear of becoming breathless, and end up being overweight.
But in a small minority of patients, poorly controlled asthma can leave them too breathless and fatigued to eat properly. Furthermore, a few asthma medications can cause upset stomachs or thrush infections in the mouth, leading to poor appetite.
Recording this information will help you recognize asthma attacks and head them off before you become seriously ill. Your doctor will also use this diary to evaluate how well your asthma action plan is working.
If the highest PEF reading is less than 80% of your personal best, you must follow the instructions given by your health care provider in your asthma action plan. Also remember to check PEFs more frequently that day, including an evening PEF.
