What kind of specialist should see a person with very low cholesterol?

Internist. There is no evidence that a low cholesterol is a cause of any medical issues. Some chronically ill patients may have a low cholesterol but it can also be found in healthy people. It is worthwhile to have a complete physical to exclude any underlying disease.
Lipidologist. Lipidologists specialize in disorders of lipid and lipoprotein metabolism. To find a lipidologist near you go to www.Lipidboard.Org, click "verify status" at the top of the page, then enter a search term (e.g., state, city and state, etc.) to find a lipid specialist near you.
