carbon dioxide retention
Carbon dioxide retention occurs when the body is unable to effectively remove this waste gas through exhalation. Normally, our lungs expel carbon dioxide produced by cells during metabolism. If lung function is impaired—due to conditions like chronic obstructive pulmonary disease (COPD) or other respiratory issues—carbon dioxide can build up in the bloodstream. This buildup can lead to symptoms such as shortness of breath, fatigue, confusion, and may affect the body's acid-base balance. Proper lung function and ventilation are essential for eliminating carbon dioxide and maintaining overall respiratory and metabolic health.
