Reduced Lung Function: Obesity is associated with reduced lung function, characterized by decreased lung volumes and impaired respiratory mechanics.
Mechanical Impact: Excess body weight places mechanical pressure on the chest and diaphragm, limiting the expansion of the lungs and hindering airflow.
Increased Risk of Respiratory Conditions: Obesity increases the risk of respiratory conditions, including asthma, chronic bronchitis, and obstructive sleep apnea, which further contribute to compromised lung function.
Inflammation: Adipose tissue in obesity releases pro-inflammatory substances, contributing to chronic systemic inflammation that can affect the respiratory system.
Changes in Respiratory Muscle Function: Obesity can alter the function of respiratory muscles, making it more challenging to maintain optimal breathing patterns.
Impaired Gas Exchange: Reduced lung function in obesity can impair the exchange of oxygen and carbon dioxide, affecting overall respiratory efficiency.
Risk of Obesity-Hypoventilation Syndrome (OHS): Severe obesity may lead to OHS, characterized by reduced respiratory drive and insufficient ventilation, resulting in low oxygen levels and high carbon dioxide levels in the blood.
Exacerbation of Existing Conditions: Obesity can exacerbate pre-existing respiratory conditions, making it more difficult to manage conditions such as asthma or chronic obstructive pulmonary disease (COPD).
