You get easily fatigued doing any physical activity
If you usually run a mile every day with ease but suddenly aren’t able to (you may feel overcome by a severe flu-like fatigue), that may be a sign your heart is not pumping enough blood throughout your body.
“Activities that used to be easy and now are suddenly met with new difficulty can be a red flag that something is wrong,” says Erin Michos, MD, associate professor of medicine and epidemiology and associate director of preventive cardiology at Johns Hopkins School of Medicine in Maryland. If a good night’s sleep doesn’t fix your overwhelming exhaustion, make an appointment with your doctor right away.
