Definition

Life expectancy is the average number of years a person can expect to live based on current mortality rates. It reflects overall health and can be influenced by various factors including nutrition and chronic illnesses.

5 Must Know Facts For Your Next Test

1. Malnutrition can significantly reduce life expectancy, especially in individuals with chronic pulmonary illnesses.
2. Chronic obstructive pulmonary disease (COPD) is associated with a lower life expectancy due to its impact on respiratory function.
3. Proper nutrition can help manage symptoms of chronic pulmonary diseases, potentially improving life expectancy.
4. Inflammation and oxidative stress from poor diet can exacerbate pulmonary conditions, shortening life expectancy.
5. Life expectancy for patients with chronic pulmonary illnesses can be improved through dietary interventions that enhance lung function.
