Certain medical conditions
If you’re eating well, exercising regularly, and sleeping pretty well most of the time but you’re still feeling worn out, then it’s time to see your doctor.
There are many underlying medical conditions that can make you feel tired all the time. These can include sleep apnea, hypothyroidism, cancer, chronic fatigue syndrome, multiple sclerosis, anxiety disorders, kidney disease, depression, diabetes, and fibromyalgia. It's crucial to understand that feeling tired all the time is uncommon. There may be one or several causes if you frequently feel tired. You may feel better and have other health benefits as a result of receiving appropriate treatment for an underlying medical condition.
