In some cases, people develop this condition due to abnormal genes that are inherited from biological parents, […]

A health condition that occurs quite rarely and causes a sudden drop in blood pressure upon standing, and autonomic nervous system problems, is called pure autonomic failure (PAF).

A health condition where a fetus or baby’s lungs develop improperly is called pulmonary hypoplasia. While it can be present at birth (congenital), doctors may detect this condition on an ultrasound during pregnancy. In most cases, pulmonary hypoplasia occurs due to an underlying condition (such as congenital diaphragmatic hernia or low levels of amniotic fluid). […]

A condition in which scarring of the lung tissue occurs is called pulmonary fibrosis (PF). It affects the ability of the lungs to expand and get enough oxygen to the body. While it may occur due to certain medicines, environmental factors, or autoimmune diseases, in some cases, doctors cannot determine what exactly causes it. Usually, […]
