No one enjoys fatigue yet there are numerous reasons why it occurs. If you're a woman, often a hormone imbalance can be the culprit. It can be as simple as (and often is) low iron. Get some blood work and check your ferritin (iron stores) level. You don't even have to have anemia to feel tired from low iron! We lose iron daily as part of our natural process but women who are menstruating lose more (along with calcium)
How our thyroid is functioning can also be a major cause of fatigue so get some more blood work done and check your TSH levels.
Stress alone can also bring on fatigue so make sure to give yourself the down time and rest you need.
Another major cause of fatigue is blood sugar levels. You don't have to be a diabetic to be affected by blood sugar! Make sure you're eating often and staying well hydrated. Remember choose nutrient rich foods, not empty calories in refined sugary foods or white refined flour filled substances.
