What is Radon? Radon is a gas that you cannot smell, taste or see. Radon forms naturally when uranium, thorium, or radium, radioactive metals, breaks down in rocks, soil and groundwater. People can be exposed to radon primarily from breathing radon in air that comes through cracks and gaps in buildings and homes.
The term 'prevalence' of Ehlers-Danlos syndrome usually refers to the estimated population of people who are managing Ehlers-Danlos syndrome at any given time. The term 'incidence' of Ehlers-Danlos syndrome refers to the annual diagnosis rate, or the number of new cases of Ehlers-Danlos syndrome diagnosed each year.
Reduced life expectancy is not generally a feature of Ehlers-Danlos syndrome (EDS), with the exception of vascular type EDS (type IV). Median life expectancy for patients with vascular type EDS is 50 years because medium-sized arteries, and the intestinal tract, can spontaneously rupture.
