Exhaled Nitric Oxide

Exhaled Nitric Oxide (eNO) is a gas naturally produced in our bodies during breathing, particularly in the lungs. It serves as an important marker for respiratory health, as it indicates inflammation in the airways. Higher levels of eNO can suggest conditions like asthma or allergies, while lower levels may indicate good lung function. Doctors often measure eNO through a simple breath test to help diagnose and monitor respiratory diseases, helping them tailor treatments for better patient outcomes. Understanding eNO can aid in recognizing how well our respiratory system is functioning.
