Respiratory Acidosis is a medical condition that occurs when the lungs cannot remove enough carbon dioxide from the body. This buildup of carbon dioxide leads to an increase in acidity in the blood, which can disrupt normal bodily functions. Common causes include chronic lung diseases, such as chronic obstructive pulmonary disease (COPD), and conditions that affect breathing, like asthma or severe pneumonia. Symptoms of respiratory acidosis may include confusion, fatigue, and shortness of breath. Diagnosis typically involves blood tests to measure the levels of carbon dioxide and acidity. Treatment focuses on improving lung function and may include medications, oxygen therapy, or mechanical ventilation in severe cases.
