A board-certified internist, researcher and author of two books is offering advice to people who suffer from chronic fatigue.

To combat the symptoms of chronic fatigue, Dr Jacob Teitelbaum has a protocol he calls SHINE, which stands for Sleep, Hormones, Infections, Nutritional supplements and Exercise, ConnectSavannah.com reports.

"Chronic fatigue results in poor sleep, hormonal problems, infections, nutritional deficiencies and chronic stress. The hypothalamus uses more energy for its size than any part of the body. Severe stress can cause it to blow a fuse," Teitelbaum told the news provider.

Patients who use nutritional supplements and get regular exercise may see "significant results" in approximately 10 weeks, the doctor added.

Teitelbaum also said the current state of the economy is most likely increasing people’s stress levels and that by getting at least nine hours of sleep each night will help the body "replenish energy and promote healing" as well as protect against infections.

The doctor is the author of two books: From Fatigued to Fantastic and Pain Free 1 –2 –3: A Proven Program for Eliminating Chronic Pain Now.
