How Long After Quitting Smoking Do Lungs Return To Normal?

After quitting smoking, your lungs have the same function and size as they did before you smoked. However, your risk of developing lung cancer is higher.

According to the Centers for Disease Control and Prevention (CDC), smoking tobacco damages the lungs, and that damage can increase your risk of developing lung cancer.

Quitting smoking can reduce your risk of developing lung cancer. You can lower your risk even more by quitting after you have a medical exam.

How long does it take to heal after quitting smoking?

The length of time that it takes to heal after quitting smoking depends on several factors.

Your age and overall health are two of the most important factors. Lungs heal faster in younger people and in people who are in good health overall.

The size and structure of your lungs also make a difference. Lungs that are very small or very large take longer to heal.

Your tolerance for nicotine and other chemicals in tobacco products also matters. A lower tolerance means that your lungs have to work harder to remove the chemicals.

Quitting smoking in general can also make your lungs heal faster.

How are lung functions affected by smoking?

Smoking affects how your lungs feel and function. Your lungs need oxygen to function well. This is especially true for people who smoke or who have quit smoking.

Smoking causes blood vessels to narrow. This makes it harder for oxygen-rich blood to reach your lungs. As a result, your lungs don’t get enough oxygen.

Smoking can also cause your blood vessels to get inflamed. This makes it harder for oxygen to get to the rest of your body.

In addition to these effects, smoking can cause your lungs to be more sensitive to cold air and heat. This makes it harder for your lungs to get rid of carbon dioxide.

Smoking can also make you more susceptible to infections. This can make your lungs work harder to fight the infection.

What should you do if you think your lungs are getting worse?

A cough, shortness of breath, and wheezing are all symptoms that your lungs may be getting worse.

You may also have swelling in your chest and back.

These symptoms may mean that your lungs aren’t getting enough oxygen. If you develop these symptoms, see your doctor. They will likely order an X-ray or other imaging test to determine the cause of your symptoms.

They may also suggest that you stop smoking. This will help your lungs heal faster.

If you develop any of these symptoms after stopping smoking, see your doctor right away. Your doctor may recommend that you quit smoking.
