Hey everyone. Im 5 months out from RnY and ever since the surgery my cough has been very weak. Is this normal. Its kinda like I have less air to push through a cough. Im assuming its because of the smaller pouch. Not a huge deal. Just that if im trying to clear a tickle in my throat or any of the many other reasons that you need to cough. It takes a few more than it used to. Sorry if this has been asked before.

Generally bypass surgery should not degrade lung function. In my case it actually improved my lung function. I had asthma and several years after surgery, I was able to completely get off all my asthma prescription medicine. Surgery might affect lung function right after the surgery because of blood clots but at 5 months post-op, I would think you are well beyond the danger stage. After surgery, they recommended that I use a spirometer. If you still have the one you were given, you might pull it out and measure your lung capacity. A spirometer is an apparatus for measuring the volume of air inspired and expired by the lungs. A spirometer measures ventilation, the movement of air into and out of the lungs. The spirogram will identify two different types of abnormal ventilation patterns, obstructive and restrictive.
