Chronic bronchitis is a diagnosis given when a person has had cough with phlegm for a period over three months in two consecutive years, as well as airflow obstruction. The most common cause of this condition is smoking (90 percent of cases). As a result, this is the first area that needs to be addressed to improve a patient’s outlook. The likelihood of your loved one successfully quitting smoking increases with the more support they are given. A reliable caregiver who has a consistent presence in your loved one’s life will be an excellent tool in this effort. Medication and supplemental oxygen administration, exercises that strengthen the respiratory muscles, and proper nutrition are also important aspects of care for this condition.
