Other chronic respiratory diseases

Besides Asthma and Chronic Obstructive Pulmonary Disease, there are many other Chronic Respiratory Diseases. Below is an overview of the most common chronic respiratory diseases.

  • Overlap Syndrome
  • Obesity Hypoventilation
  • Central & Mixed Apnea
  • Allergic rhinitis and sinusitis
  • Bronchiectasis
  • Obstructive sleep apnoea syndrome
  • Pulmonary hypertension

Chronic obstructive pulmonary disease offers a huge burden on respiratory disease, it can ‘overlap’ with other respiratory diseases including bronchiectasis, fibrosis and obstructive sleep apnea (OSA). COPD alone is responsible for morbidity and mortality and a common feature with contrasting clinical outcomes occurs in COPD ‘overlap syndromes’. Overlap Syndrome covers a larger degree of heterogeneity in COPD,

  • Asthma-COPD overlap syndrome (ACOS),
  • Bronchiectasis-COPD (BCOS),
  • Fibrosis-COPD (FCOS) &
  • OSA-COPD (OCOS).

Obesity Hypoventilation

Obesity hypoventilation syndrome is the combination of obesity i.e body mass index above 27 kg/m2, hypoxemia i.e lack of oxygen levels in blood during sleep, and hypercapnia i.e increased blood carbon dioxide levels during the day, resulting from hypoventilation i.e excessively slow or shallow breathing.
