It is possible to live a normal life with one lung breathing, but regular review is required. People who are left with only one side of lung tissue due to surgical removal or other reasons are able to live a normal life. The lung tissue on one side is able to provide the gas exchange and oxygenation needed by the body to keep them alive, but strenuous exercise and heavy labor are generally not possible. Regular checkups and a healthy lifestyle are recommended. If you don’t have a healthy work routine, in the later stages of life, one lung may lead to a series of complications, including hypoxemia, chronic pulmonary heart disease, respiratory failure, etc. Some of the people with one lung may need to be resuscitated in emergencies, so you need to observe your own changes in symptoms and signs and seek medical attention in case of any dangerous situations.
