Restrictive diseases

Definition

Restrictive diseases are respiratory conditions that cause a decreased ability to expand the lungs. This leads to reduced lung volume and diminished lung capacity.

5 Must Know Facts For Your Next Test

1. Common causes of restrictive diseases include pulmonary fibrosis, obesity, and neuromuscular disorders.
2. Patients with restrictive diseases often experience symptoms like shortness of breath, rapid breathing, and chronic cough.
3. Diagnosis typically involves pulmonary function tests (PFTs) showing reduced total lung capacity (TLC) and forced vital capacity (FVC).
4. Unlike obstructive lung diseases, restrictive diseases do not primarily affect the airways but the lung tissue or chest wall.
5. Treatments for restrictive diseases may include corticosteroids, immunosuppressive drugs, or physical therapy to improve breathing efficiency.
