Who gets FM?

Medical research indicates that over 6 million people in the US have FM, and that 80-90% of them are women. On the other hand, there is an estimate that about 1 million people in the U.S. suffer from ME/CFS. However, about 80% of those with ME/CFS also suffer from FM—or about 800,000. Thus most people with ME/CFS also have FM, but most people with FM don’t have ME/CFS.
