    What are Fatigue\Exhaustion?

  • Fatigue is when you are feeling overtired or exhausted, lack of energy, and a strong feeling of sleep. It is a common symptom for many for change in lifestyle and many other reasons. This symptom severity range might be mild to serious.
  • There are two major types of fatigue: physical and mental fatigue:
    • A person suffering from physical fatigue may have physical difficulties doing the things they usually do, such as climbing stairs. Symptoms include muscle weakness and the diagnosis may involve performing a strength test.
    • With mental fatigue, a person may have a harder time concentrating on things and staying focused. They may feel drowsy or have difficulty staying awake while working.


  • Fatigue causes are mainly divided into 3 categories:
    • Lifestyle factors: Not taking adequate nutritious food, taking certain medications, emotional stress, lack of sleep, lack of physical activities, boredom, consuming alcohol regularly, drug addiction.
    • Physical or medical health conditions: Malaria, tuberculosis, infectious mononucleosis, cytomegalovirus, HIV, flu, hepatitis, anemia, high blood pressure, chronic fatigue syndrome, rheumatoid arthritis, massive blood loss, chemotherapy and radiation therapy, kidney disease, pregnancy, thyroid conditions.
    • Mental health issues: anxiety, depression, and seasonal affective disorder


  • To diagnose the underlying cause of fatigue, your doctor or licensed health care professional will ask you several questions related to your symptoms. You can better help your healthcare professional diagnose the underlying cause of fatigue by providing complete answers to these questions:
    • Describe fatigue. Is it constant or intermittent? Is it mild, moderate, or severe? Does it happen with or after certain activities or events, such as stress, exercise, or just before menstruation?
    • How long have you had fatigue?
    • ask about other symptoms, such as a cough, digestive problems, rashes, or other concerns
    • What other symptoms do you have with fatigue?


    • There is no specific treatment for fatigue. The days of doctors prescribing a "tonic" are over, as nothing really works. The secret is to try to pinpoint the cause and then do something about it.
    • If the cause is a medical condition, treating the condition will often resolve the tiredness. For example, if you have anemia, iron supplements can treat this and the tiredness resolves as your blood count improves. Even supplementing iron levels in a low range of normal is believed to help with fatigue. If you are found to have hypothyroidism, a pill to replace the missing thyroid hormone is usually very effective and you will find that you have more energy.
    • If the cause is a side effect of the medication, it may be possible to switch to something that works better for you.
    • If you are found to have chronic fatigue syndrome, you may be referred to a chronic fatigue specialist for help through psychological therapy, gradual exercise therapy, or medications.
    • If you have anxiety or depression, this can be relieved with talk therapy, cognitive-behavioral therapy (CBT), medication, or several other possible treatments.
    • It may seem strange, but physical exercise can actually be very effective in treating fatigue. Any moderate exercise, like walking, swimming, or biking, can help you feel less tired. Regular workouts are a great way to stay healthy.
    • If you don't get a good night's sleep, it's tempting to try to "make up" by taking naps during the day when possible. This really won't help; in fact, it can get your body clock out of sync, so you may end up sleeping less well at night. There are many ways you can try to improve your sleep if you have insomnia, and this, in turn, can improve your tiredness.
