Do you feel tired all the time? Find out what may be causing your fatigue (via WebMD):

  1. What you eat. Consuming caffeine and sugar to keep you energized may backfire because it causes major fluctuations in your blood sugar levels, leaving you more tired than before. Instead, eat lots of fruit, vegetables and lean protein to keep your blood sugar levels stable. Eating this healthy diet will also help you to carry less weight.
  2. How much you sleep. The importance of sleep cannot be overstated. If you have trouble nodding off, avoid caffeine and alcohol in the hours before bedtime and keep your bedroom quiet, cool and restful.
  3. How much you exercise. While you might be worried that you’re doing too much in our over-scheduled times, chances are you aren’t doing enough when it comes to exercise. Though it seems counterintuitive, an excellent remedy for fatigue is vigorous exercise. Get at least 40 minutes, four days per week. 
  4. Anemia. If you’re exercising and eating healthfully, but still feeling tired, you could have one of multiple health conditions. Anemia, an iron deficiency, is easily detectable through a simple blood test and can be treated by eating iron-rich foods like dark, leafy greens, or taking an iron supplement.
  5. Deficiencies in key nutrients. For example, low potassium levels can cause fatigue, and can be checked with a blood test.
  6. Hypothyroidism or hyperthyroidism. Having either an under-active (hypo) or overactive (hyper) thyroid can cause ongoing fatigue. A thyroid test can help determine your thyroid function. For those with a thyroid condition, effective prescription treatments are available.
  7. Diabetes. If you’re dragging all day, and also experience blurred vision or frequent urination, you may want to take a blood test for diabetes.
  8. Depression. If your fatigue is paired with sadness or a lack of appetite, you may be experiencing depression. Do not keep your feelings to yourself. Schedule an appointment with your doctor, who can diagnose your condition and recommend the right treatment plan for you.
  9. Sleep problems. If you get enough sleep, but feel that sleep does not cure your tiredness, you may want to visit a sleep lab, particularly if you snore. Snoring can lead to sleep apnea, where people stop breathing for several times during the night. The condition is treatable.
  10. Undiagnosed heart disease. If you start to feel that things you once did are becoming more difficult, or if you start feeling worse when you exercise, see your doctor to rule out heart disease.

Most importantly, remember that the vast majority of fatigue can be cured with the first three tips: eat healthy, sleep more, and exercise more.
