If you feel an overwhelming sense of fatigue, it may be something to address, especially if you've been sleeping normally. So, if sleep isn't doing enough for you, and you notice some of these symptoms of chronic fatigue syndrome, you may want to see a doctor immediately to get a proper diagnosis. Unfortunately, getting a diagnosis can be challenging because the symptoms of chronic fatigue are similar to many other illnesses.
"Chronic fatigue often starts suddenly, with flu-like symptoms. But unlike the flu, it can last a lifetime," Dr. Josh Axe, D.N.M., C.N.S., D.C., best-selling author of Eat Dirt, and co-founder of Ancient Nutrition, tells Bustle. "We still know very little about chronic fatigue, and sadly, the cause is still unknown. While researchers continue to search for the root cause of CFS, there are preliminary findings that hormonal imbalances, poor immune system response, viral infections, chronic low blood pressure and nutritional deficiency are contributing factors." Although chronic fatigue is hard to peg down, knowing the signs can be a bit of extra help in determining if it's worth getting a second opinion. And if you do wind up getting a diagnosis, you and your doctor can determine the best course of treatment for you. Here are seven signs experts say might mean you have chronic fatigue syndrome.
