  • Q&A with Australian Health Practitioners

    Why am i always tired?

    I have allergies to dust mites and am sensitive to sulphites. I also have asthma on top of this. I saw my GP recently to enquire about my excessive tiredness. Blood test results have come back "normal" so my GP suggested it could be a syndrome similar to sleep apnea. I couldn't understand what he called the syndrome and I was wondering if there was more information available. Thanks

    We would suggest that you ask your GP for a referral to a sleep specialist so that you can obtain a proper diagnosis of your condition.  Sleep is now recognised as one of the pillars of good health and medical sleep disorders such as sleep apnea are shown to contribute to other serious health problems.

    I don't know how extensive the clinical investigations that your GP organised for you were but it might be worthwhile getting your thyroid gland function checked out.

    The thyroid gland makes a hormone called thyroxine (it comes in two forms, T3 and T4) - a common sign of low levels of thyroxine ("hypothyroidism") is fatigue.

    Production of thyroxine is controlled by two other hormones (Thyroid Stimulating Hormone - "TSH", made by the pituitary gland and Thyrotropin Releasing Hormone - "TRH", made by the hypothalamus).

    "Blood test" measurements of T3, T4, TSH and TRH levels are easy to do.

    If those tests reveal anything of concern your GP will be able to refer you to a specialist endocrinologist who will be able to carry out further investigations and then discuss treatment options with you.

    All the best.

    As mentioned above there could various reasons that could be resulting in fatigue. Given the information you have provided I suggest the following:

    • Assess lifestyle factors that may contribute to energy levels including diet,  activity and sleep
    • Investigate further pathology (including liver function, Thyroid function – TSH, T3 & T4, sec hormones,  and iron )
    • Seek referral to a gastroenterologists  as the gut (and intolerances) can contribute to absorption and vitamin/mineral issues
    • Ensure your asthma and allergies are well managed, taking medications as prescribed

    Wishing you all the best.

    Very good posts above thank you.


    In addition to checking thyroid function, iron levels, it is also important to consider coeliac disease which is not uncommon if you are Caucasian.


    However it sounds like your GP would have covered these tests. It is prudent to continue seek medical attention if your symptoms persist, even if the intial tests are normal.
