Weight gain and rising BMI are associated with decreased lung volumes, reflected by spirometry's more restrictive ventilatory pattern. Excessive Fat Deposit around the abdomen further leads to worsening lung function and respiratory symptoms. Lower body fat deposition is less associated with respiratory symptoms in comparison.
It is hypothesized that the deposition of fat tissue in the abdominal wall and around the abdominal organs hampers movement of the diaphragm and reduces lung expansion during inspiration and reduces lung capacity. The function of the respiratory muscles also deteriorates in obese patients much like in respiratory diseases like chronic obstructive lung disease (COPD).
Obesity affects the respiratory system health adversely in many ways. Some of the health effects of obesity on the respiratory system include diseases like:-
Exertional dyspnea – This is basically severe breathlessness caused due to minor exertions. This is a common feature among obese individuals.
Obstructive sleep apnea syndrome – This condition leads to the closing or narrowing of the airways during sleep leading to snoring, repeated waking and lack of adequate and restful sleep.
Chronic obstructive pulmonary disease (COPD)
Asthma – Obese patients are more at risk of asthma exacerbations. Studies show the prevalence of asthma is higher by 38% in overweight patients and by 92% in obese patients. Obese patients with asthma also get more acute attacks, need more asthma medication, need more frequent visits to the emergency department (ED), and have more hospital admissions than non-obese patients with asthma.
Obesity hypoventilation syndrome – Obese individuals have low lung reserve and may thus have difficulty in providing enough oxygen for their bodies. This may lead to hypoxia or low oxygenation of the body.
Pulmonary embolism – This is a serious condition where a blood clot gets lodged in the blood vessels of the lungs leading to a life-threatening medical emergency.
Aspiration pneumonia – Due to the short and narrowed airways there is a possibility of the stomach contents moving into the lungs. This causes severe pneumonia caused by harmful stomach acids.
