Why am I so tired?

Understand fatigue and burnout

I know so many people who are exhausted.  Completely and utterly exhausted.  My friends, my patients, my work colleagues, often myself.  Fatigue, exhaustion, burnout – it seems to be the chronic disease of our time and I find it quite depressing thinking about it and its impact on our ability to not only work, produce and succeed in life but also to enjoy life, enjoy our families and enjoy ourselves.  

The first step in ‘fighting fatigue’ begins with finding the underlying cause of the fatigue, finding out why you are so tired. Unfortunately, this is a lot easier said than done.


Is your lifestyle making you tired?


Start by looking at your daily habits. Are you a parent who works a full day in the office, comes home to cook and clean, put your kids to bed and then...sit down at your computer to do a few more hours work...often until after midnight? If yes, then there is your reason for being so tired.

To be honest, how on earth can anyone live like this and not be tired? If you think you can survive on 3-4 hours sleep then read my blog, One Good Reason to Sleep, and hopefully you will start making sleep a priority.

Similarly, do you have a coffee for breakfast, skip lunch, have a chocolate or some chips late afternoon and then usually pasta for dinner? If yes, then of course you will be tired!


Is an underlying health condition causing your fatigue?


If you can’t find the cause of your fatigue in your lifestyle, then you need to start looking at common health conditions that cause fatigue. Visit your doctor for a full check-up and also ask him/her to run a few tests to investigate the following common conditions that are all associated with fatigue:

  • Anaemia – low iron levels are common in growing children, menstruating or pregnant women and vegetarians and they cause fatigue, decreased immunity, headaches and dizziness. 
  • Hypothyroidism – this is a major cause of fatigue, especially if that fatigue is accompanied by weight gain, dry skin and hair, constipation and depression.
  • Infection – I feel I am opening a can of worms when I mention this topic. There are so many pathogens that can cause chronic fatigue as a consequence but the most common are Borrelia burgdorferi and Borrelia mayonii (Lyme Disease), Epstein Barr Virus, Cytomegalovirus and chronic lung or gut infections.  Your doctor will be able to help you investigate these.
  • Low vitamin B levels – the B-vitamins are responsible for maintaining your nervous system, mental health and energy metabolism.  I like to call them the ‘stress vitamins’ because they are quickly used up by your body in times of stress.  If you are going through a stressful time or have experienced a great deal of stress in your life, then ask your doctor to check your vitamin-B levels.
  • Low vitamin D levels – although not really an ‘energy’ related nutrient, low levels of vitamin D negatively affect the absorption of many minerals and result in muscular weakness and bone pain as well as depression.  If you are struggling with ongoing fatigue accompanied by a lot of aches and pains or muscular weakness, then have your vitamin D levels tested.  This is especially important if you do not get enough sunshine. For example, if you work night shifts, live in a highly polluted city or spend far too many hours in the office.


What else can be making you so tired?


If your doctor has ruled out any health conditions that may be making you tired, yet you are still struggling with chronic fatigue, then you need to ‘throw the net wider’ and start looking at other causes of fatigue.  These include:

  • Medications – unfortunately lethargy and fatigue are a common side effect of many medications.    Medications for high blood pressure, high cholesterol, reflux/heartburn, antibiotics, antihistamines, antidepressants and those used to treat anxiety and insomnia are all known to have fatigue as a side effect (Neel, 2012).  Never take yourself off a prescribed medication as this can be dangerous, but instead talk to your doctor who may be able to adjust your dosage or prescribe an alternative to what you are taking.
  • Chronic inflammation, dysbiosis or an unhealthy microbiome, leaky gut and food intolerances are all associated with chronic fatigue and I will discuss these more in detail in later blogs.
  • Menstrual problems – many women struggle with painful, heavy or too frequent periods and long term these problems can be utterly exhausting and even debilitating.  Unfortunately, the more exhausted you become, the more irregular and difficult your cycle will be so it is very important that you focus on good nutrition and a healthy routine in order to keep your menstrual cycle as balanced as possible.
  • Menopause - chronic fatigue is also common in menopausal women whose sleep often becomes disrupted by hot flushes or night sweats. For hints and tips on how to survive menopause, read my blog, Managing Menopause Naturally.

If you eliminate all of the above as possible causes and are still exhausted, then you need to start exploring the deeper reasons for your fatigue - often these are more than simply pathophysiological. If you need some help and guidance then please book a consultation with me.
