Lungs Recovery After Quitting Smoking
How long after?: If you just quit smoking very recently, the wheezing can come from the resultant increase in sputum production that occurs after the bronchial tree's mucociliary elevator starts up again (long story) and as such may stop after several weeks. However, the fear would be that emphysema has already set in, and this wheeze would be permanent, then. ...Read moreSee 1 more doctor answer
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
Stopping Smoking: It is often thought that in the fifth year post cigarettes much of lung function has returned. But, this is not always the case. Any days post cigarettes are good for you. ...Read more
Got it backwards : Nicotine (nicotinic) receprors are so named because they have an affinity for bonding with nicotine. That's where nicotine exerts its effects. They were there before you started using nicotine, and will be there after you stop. Think of any other receptor site that has an affinity for a specific biochemical (serotonin, dopamine, endorphin, acetylcholine, gaba, etc). ...Read more
No Butts : Yes, depending on the amount and length exposure (pack years = packs of cigarettes smoked daily divided by the amount of years smoked). Research has shown that lungs of x-smokers are indistinguishable from those of non-smokers 10-15 years after one has quit smoking. The body has the tendency to heal itself. ...Read more
Yes, but depends: on how much damage has been done. If this is you, and you have been smoking for 15-20 years (my guess), it will take time to clear out - cough may actually increase to clear out the accumulated gunk in the airways as the little ciliated hair cells start to work again. The conventional wisdom is that things clear up in about 10 years, except the discoloration (black spots) on lungs do not go away. ...Read more

Yes!!!: Congratulations on quitting! back in june, a study was published demonstrating that the longer one stops smoking, the better.

Not really: Consider asthma a lifelong condition like a missing leg, only for asthma it is not as obvious and can be controlled by avoiding triggers. It is not like appendicitis where you can take it out & you are cured. Smoking is a well known trigger to lung irritation that will always aggravate asthma to some degree. Stopping may actually let you go for years between events, or just reduce their intensity. ...Read moreSee 2 more doctor answers

Varies: It depends on a lot of things.

For sure, stopping smoking is your best chance to improve. ...Read moreSee 1 more doctor answer
Variable: Tobacco addiction is one of the strongest out there. It depends upon your motivation to stop, your general psychological make up and whether you have a good plan with diverting interests to lower the need for tobacco.

Still coughing 2 weeks after sinus infection/bronchitis. Trying to quit smoking. Worried/scared of copd?
Silver linings: Sometimes it takes feeling ill to help people really get serious about quitting. If so, it's doing you a favor. 34 is not too old to have the changes you make be very significant - you should be able to avoid COPD (a good choice!) Worry may not be needed and once it motivates you - send it packing! Two weeks is still w/in normal range for healing, but see your Dr. if it goes on. Get a Star! ...Read more
