Final answer:
Restless Leg Syndrome can result from conditions like iron deficiency or diabetes, and first-line treatment often includes lifestyle changes and, if necessary, dopaminergic agents.
Step-by-step explanation:
The student has asked about Restless Leg Syndrome (RLS), specifically regarding its secondary causes and first-line treatment options. Secondary causes of RLS include iron deficiency, kidney failure, diabetes, and neurological conditions. Proper diagnosis often requires blood tests to identify underlying causes, like iron deficiency, which can be treated with iron supplements.
In primary RLS, where no secondary cause is found, the first-line treatment typically involves lifestyle changes such as regular sleep habits, exercise, and avoidance of caffeine, alcohol, and tobacco. For some patients, pharmaceutical treatments may be necessary, with dopaminergic agents like pramipexole or ropinirole often being used as a starting point.
