In most pneumonia cases, even severe ones, the lungs of pneumonia patients completely recover. That said, it may take a while before that happens, especially for older adults or those with an underlying medical condition. Even though treatment should neutralize the viral or bacterial infection within one to two weeks, the effects of pneumonia can sometimes continue long after the infection is gone. If you are one of the lucky ones, you should feel fine returning to regular activity within a week. For others, it could take a month to six weeks before your lungs start feeling normal again, and up to six months before your energy levels return to normal. With that being said, it is critical not to rush your recovery! Instead, we urge you to listen to your body and rest whenever you feel weak or tired. Our board-certified physicians and nurse practitioners would be more than happy to provide expert medical guidance and treatment to ensure you make a complete recovery from pneumonia in due time!
