My husband continue to have real low blood pressure after dialysis and has a bad cough.  He is a heart patient but he doesnt take his Coreg on the day he goes to Dialysis. He bottoms out and he is drinking 1.1/2 liters of water per day so there is no dehydration.
HIT hank for asking to ChatDoctorI can understand this problem, the low blood pressure can not be itself, there certain obvious causes for this and that has to be treated accordingly, fist thing this should be confirmed, in your husbands' case hypokalemic status could because and chances of some oozing or leaking of blood is likely, in short underlying cause of hypotension need to be treated, hope this information helps you have good day.
