A friend who is diabetic & has had angio 5yrs back is complaining of strained breathing & sleeplessness.says he has to inhale hard to breathe.help!

Many possibilities: Hi. I recommend your friend see a good diagnostician sooner than later. Those symptoms could reflects problems with the heart, lungs, kidneys, etc, etc. Serious conditions should be evaluated first. I hope he diligently controls his diabetes, blood pressure, lipids, and doesn't smoke. Please encourage him to see a good doctor!

Friend: Your friend should see his/her doctor and be evaluated for this problem.

Call his doctor.: Talk to a nurse, who can ask his doctor if he wants you to bring him to the office or to a hospital-based ReR.
