It could be Asthma , have you ever smoked ? Reason i ask is i was a smoker for for 35yrs then i stopped and now have Asthma , but before i stopped i had big Problems with breathing but am not so bad now . I take an inhaler ( Preventer ) twice daily clenile modulite & if needed i take salamol inhaler , hope this helps but if not hope you get sorted soon x

I second 👆🏻 it could definitely be asthma, but it could also be related to CHF. I'd suggest visiting a pulmonologist and a cardiologist. They'll probably want to test your lung capacity and pulse oxygenation level. I've had lifelong asthma and am carrying around extra weight myself. It can definitely be hard. I also noticed I've had issues with my lungs and breathing since having COVID three years ago. Idk if you've been there, but it could be related as well. Sending hugs. 💕

My dad had breathing problems with his CHF. That was a big issue for him. COPD and asthma get confused often I hear (I have asthma myself) so maybe that’s it? I hope you get a correct diagnosis soon!

There is new understanding of subsets of asthma that cause long term damage and can look like COPD. Have you had a differential white blood cell test? You might have what I do which is called eosinophilic asthma. Eosinophil are white blood cells that are supposed to attack parasites, funguses, and allergen, but can go out of control and attack you instead. They cause swelling, weight gain, heart damage, and chronic shortness of breath. I hope you find relief
