If your husband is coughing up blood, a doctor can most definitely do something to treat that!!! Coughing up blood is NOT typical of COPD, but can happen with an infection.
Best wishes to you both!
I am very sorry to hear of your husband's condition, especially at age 48. There is a condition called alpha-1 antitrypsin deficiency that results in emphysema at a young age. You should ask his doctors to test him for this condition; it is a blood test. If he has this condition, it may be too late for him, but if you have any children or if he has any siblings who might also have inherited it, it would be extremely important for all of them to know that they might be at risk for severe emphysema. You might want to call the Alpha-1 Foundation (800) 785-3177 for more information about this disease.
There are a number of possible causes of coughing up blood. Some of these are infectious, for example tuberculosis (TB) that would put you in danger, so you definitely should work with his doctor to determine the cause of the bleeding. Do not delay.
Good luck.
GOD BLESS you and him so sorry life throws curves at us. i pray ya lean on him and he walks ya throught this.
