The National Library of Medicine and Centers for Disease Control and Prevention describe Chronic Fatigue Syndrome (CFS) as “a disorder that causes extreme fatigue.” The symptoms felt in CFS are not the typical symptoms of fatigue that are experienced and go away after a period of rest. Chronic fatigue lasts for extended time and encroaches on the activities of daily living. A doctor must rule out other disease entities to make a definitive diagnosis of CFS. This can sometimes be difficult to pinpoint at first because other illnesses can cause similar symptoms. Anyone can have Chronic Fatigue Syndrome, but it is most commonly seen in females who are between 40 and 60 years of age. No cure exists for CFS, but symptoms can be controlled. Hyperbaric oxygen therapy has been studied and shown to help patients achieve the treatment goal of symptom improvement. Studies are underway, both in the US and in other countries aimed at documenting the positive impact HBOT has on chronic fatigue syndrome and the biologic pathways that are responsible for its success.
