My low weight has been a concern for a long time. I found some good tips for weight gain, muscle strengthening, and increasing stamina. I have found that it is possible to gain about a pound a week. The weight training helps to put the weight where it needs to go! I walk quite a bit, too. While I was in the hospital last month with bronchitis ( I was too busy to heed the warning signs that I was getting sick) my lung function tests were very low. I was freaked out for sure! The outcome was that I needed home oxygen. My doctor even suggested that I quit my parttime job. After the antibiotics kicked in and I got home from the hospital, I began the changes that would affect the rest of my life. I quit smoking the day I went to the hospital. (week 5 with no cigarettes!!)
I continued on my meds, ordered my home o2 concentrator and got an o2 finger monitor to track my oxygen levels and I did a lot of pursed breathing. My levels were up in the mid-90s. I feel that just stopping cigs was making all the difference. I saw my doc a week after I was discharged. He was a little surprised. He wrote a return to work note for my boss. I am on oxygen at night and while I exercise and weight train. I have gained about 4 pounds. That is harder than one might think and it still goes up and down by a pound or so. I bought a spirometry for home use and it was also an eye-opener. When I first started, (two days after I got home from the hospital) my readings were in the 30's.
UGH! It's been a lot of hard work with lung expansion exercises and deep breathing and getting out every bit of air that I can, I am having some great improvement in my readings. I am consistently in the high 40s to mid 50 %!! I even had a 59% twice!! COPD is such a complex illness and it's going to take all of us doing all we can each day to take care of ourselves each day. There is so much going on every day just to make it through the day and being able to breathe! This started out about weight gain and I just got off on every subject. Sorry about that. I just know that there is help and there is hope for all of us!! Blessings for the day!

I went from 146 to 95, am 5' tall, no actually 4' 11", I forgot I lost an inch. I've read that it's normal in stage 4 (end stage) to lose weight. I've been in very severe stage 4 for at least 3 years. I have found that I really don't have much appetite plus it takes a LOT of energy to eat! I am on 3 L o2, 24/7. One day out of curiosity I took my o2 off while eating, went down to 82%. That said, I just try to make everything I eat count, as in high protein & carbs for energy. I've even been using the store brand ensure for when I just can't force myself to eat.

I too lost a lot of weight at one stage.
The specialist at the Wellington Public Hospital explained that I was using more energy , on a daily basis , to breathe than I was getting from my daily food intake. First you burn fat the you start eating into muscle mass. Danger !!!
I was sent for dietary advice and attended a pulmonary rehab course to learn how to exercise given the limitations of COPD.
Am now back to normal weight , 3 years since giving up the smokes and have my daily hot lemon and honey drink.
Life has improved and people tell me I look better. I feel better.
Eat wisely and snack wisely !
Best Wishes.
