Veronica, hi my name is Danny I was diagnosed with stage 4 copd, and chef. I was about 165 to 175 pounds all my life. I was diagnosed 4 an half years ago when I was 45 years old. Within a few months I blew up to 328 pounds the doctors put me on lasik, fenfibrate, nitro, oxygen, lug pumps for copd. I went to these 2 great doctors a heart specialist and a pulmonologist I dropped 121 lbs in for months, my heart dr. Put me on flecainide, and it's done wonders but I also take metoprolol, isosorbide, they all done great, but my pulmonologist put me on a trilogy ventilator with oxygen this machine takes the stress off of your iui r lungs and heart while your sleeping,an let me tell you I'm doing great. Not that I can climb stairs or anything like that but I'm get around so much better with alot less heart episodes. Talk to your doctor an let them know your concerns, and if you have to make them listing.so I know what your going through so dont give up. I'll be praying for you, God can change it all around. If you ever need to talk look me up on Facebook under Eulos Speyrer, Danny is my nick name. Have a blessed on!.
