Is there a difference between primary RLS and secondary RLS? There are two types of RLS, primary and secondary. Primary RLS, also known as idiopathic RLS, is the most common type of RLS5 and can be hereditary. Primary RLS has no known cause. Secondary RLS occurs as a result of an underlying medical condition or in association with the use of certain drugs. For example, some conditions that may cause secondary RLS include kidney failure, low levels of iron, anemia, pregnancy, and peripheral neuropathy. Stress, diet or other environmental factors may also play a role in the development of RLS.
