Fatigue occurs in many medical conditions and can range from mild to severe, it can also happen due to lifestyle factors like poor nutritional choices, lack of exercise, etc. Since fatigue can occur due to so many reasons, it is advisable to get a Fatigue Test to determine and clearly diagnose your condition.
