I've had the same shortness of breath when bending over. For me, this is often an early indicator that my asthma is getting out of control - it can take several minutes just to put on shoes, and trying to pick something off the floor can be very challenging. Walking upstairs knocks the wind out of me. Other asthma symptoms such as constant difficulty breathing and coughing may not begin for days or weeks after the bending symptoms. I also have acid reflux & I'm close in age & physical condition to you. My asthma doctor told me each patient may experience different asthma symptoms (or combinations of symptoms) & the sooner you can recognize them occurring the sooner you can begin appropriate treatment to prevent or minimize an asthma attack. I had extensive tests of heart, lungs, blood, etc which ruled out other causes so my doctor felt positive my symptoms were asthma related.
Is your shortness of breath when bending over relatively new or have you experienced this for a long time? Please discuss this with your doctor if you haven't already done so because your shortness of breath needs proper diagnosis/treatment. It's taken time and frequent medication/dosage changes to find what works best for me on treating asthma, but it's now reasonably well under control and I'm quick to alert my doctor if my symptoms begin to flare up.
