My husband has been diagnosed with Emphysema, COPD and heart problems. I'm worried as to how long he has.

How old is ur husband? If u don't have it already ask one of his doctors for an order for hospice. They will evaluate to see if he qualifies. Medicare pays for this.

You are understandably worried. Ask him to see a doctor to prescribe breathing exercises to increase his lung capacity. Without exercise it will only get worse quickly. You can get him walking and eating right. He may need to lose some weight. Again, talk with his doctor about his prognosis and what lifestyle changes can help.
