Asbestosis primarily affects the lower lobes of the lungs. The lower lobes are the lower sections of the lungs that are closer to the diaphragm. These lobes are more susceptible to asbestos fiber deposition due to the way asbestos fibers travel through the respiratory system.
When asbestos fibers are inhaled, they can become lodged in the small airways (bronchioles) and the air sacs (alveoli) of the lungs. Over time, the body’s immune system responds to the presence of these fibers, leading to inflammation and scarring (fibrosis) of the lung tissue. This fibrotic process primarily affects the lower lobes of the lungs.
However, it’s worth noting that asbestosis can also involve the upper lobes of the lungs, although to a lesser extent. The distribution of fibrosis can vary among individuals and may depend on factors such as the duration and intensity of asbestos exposure and individual susceptibility.
Radiological imaging studies, such as chest X-rays or high-resolution computed tomography (HRCT) scans, can help visualize and evaluate the extent and distribution of fibrosis in the lungs. These imaging techniques can provide important diagnostic information and help differentiate asbestosis from other lung conditions.
If you have concerns about asbestosis or have a history of asbestos exposure, it’s important to consult with a healthcare professional who can assess your condition, order appropriate tests if necessary, and provide the necessary guidance and treatment.
