It's the little things that get to you—the daily commute, a grueling schedule, an important deadline—they can take a toll on your health and could be the reason you're always exhausted. However, reports show that feeling tired all the time can also be caused by other medical conditions that should be taken seriously.

Feeling tired most of the time even after a full night’s sleep already raises a red flag.
Fatigue can be the cause of a underlying health problem like thyroid disease, diabetes, and depression.

According to Sandra Adamson Fryhofer, MD., an internal medicine doctor in Atlanta, you shouldn't shrug off feelings of exhaustion, especially when they happen way too often. She recommends changing your lifestyle for two to three weeks by trying to get more sleep, eating better, and drinking lots of water.

Does your fatigue come with breathlessness?
According to TIME.com, that’s a possible sign of cardiomyopathy, a disease that causes overgrowth of the heart muscle. If the tiredness doesn't go away, the best solution is to consult a doctor for medical advice.

It's also important to have a medical diary where you can jot down and describe how tired you actually felt so the doctor can diagnose you properly.
