There is a difference between being tired and fatigue. Everybody is  getting tired at the end of the day, and once in a while we still are  after a too short night of sleep. We may feel like an afternoon nap, or a  lie in – that’s all rather normal.                
Why so tired?
    With fatigue I mean feeling constantly worn down. Being  tired even when the night was long enough; the feeling that although  the sleep was deep and dreamless one hasn’t slept at all. One is able to  get through the daily tasks, even finds a laugh when chatting with the  girls, but there is always this feeling of having to push through; there  is no natural flow, one is clumsy and forgetful and creativity has left  the brain.
                So one is checking the calendar and is somewhat relieved to  see that it is ‘the week before’. Thank God, it’s just one of those  months, and there will be payback time: When this will be over the sun  usually is shining a bit brighter, even. But not this time! So the  search continues: Well, a lot of people have a cold: I may come down  with something; it’s almost spring: This change of seasonal climate is  stressful on the body and one is worn down by central heating and lack  of oxygen.
        I need a pill!
    The re-installed power walking sessions, however and  the garden work are not helping, in contrary: Instead of a rosy, fresh  air complexion I look grey like an old bed sheet, the hair is lifeless,  and I only have to look at food for it to appear on my thighs. The head  clouds are getting bigger and the workload that lies ahead becomes ever  more overwhelming: One already has to think about summer holidays and  it’s only those few month to squeeze everything in – the garden, Easter,  some travels to see family, preparing the BBQ place to be ready for the  May Bank Holidays, sport definitely needs picking up and sh... the  windows and the garden fence need painting, and all I want to do is to  sit in my armchair with biscuits and tea and stare at the wall – even  choosing a movie from the DVD collection is too much of a decision. It  would be so great to have a pill to make it all go away. Well, maybe  there is one: 
        Iron!
    Iron is needed to build the haemoglobin in the red  blood cells, and that is the stuff which is transporting the oxygen that  we breathe in, into to cells of the body where it gets burnt and turned  into energy, so that the cell can do its job.
        How it works
    The burning process is using the same principles like a  fireplace. In order to heat a room or cook some food two things are  needed: a fuel like gas or coal and oxygen. Trying to light the fuel in a  vacuum won’t work as the oxygen is missing; there has to be oxygen to  turn the fuel into energy. This can easily be observed when  extinguishing a candle with a candle snuffer. As soon as it is put over  the candle, the flame uses the leftovers of the oxygen and then just  stops burning.
        This mechanism explains where the lack of energy comes from  when iron is missing in the body. Iron means oxygen and if it is missing  our fire has gone out or is about to, hence the body wants to save the  meagre remains for vital organs, goes into energy saving mode and tries  to put us to sleep. Additionally it signals for help. Once in a while it  might make the heart work hard in the hope to get more blood pumped and  hence more oxygen supplied - one then can feel the beat scarily loud  and clear, or it may ask for fuel, meaning food, sometimes in the shape  of weird cravings. Well, and since the body won’t waste energy to keep  skin and hair nice, one might become rather flaky and ‘beige’. Although  the typical pale complexion of an anaemic will come at a later stage.
        Oh, what a bad combination: Wanting nothing more than hanging  around and eating. So why on earth do we lose iron? It’s something  really rather solid, how does it leave the body?
        When things go wrong
    The iron lives in the red blood cells, which when everything  goes right live around 3-4 months and then get recycled and rebuild, if  something goes wrong the iron gets lost. There are five main mechanisms  involved in the iron trade where things can go wrong:
        the body is not able to build enough red blood cells to  replace the dying ones  – then something is usually wrong with the bone  marrow,
   
        - the body is not able to absorb the iron that it gets  delivered with the food – then something is wrong with the intestines,  like celiac disease,
 
 
- the body is in need for more iron, like during pregnancy,
 
 
- the body is losing a huge amount of blood, like during an  accident or operation, or
 
 
- the body is losing small amounts of blood, like during  menstruation.
Regarding the first two, one would not just feel a bit off  whack but rather sick. The underlying condition would cause further  symptoms and doctors will take care of the situation. Additionally the  symptom would probably appear rather quickly. The same is true for  pregnancy during which iron levels should be monitored and balance out.
        Balanced Diet
    Well, when losing a large amount of blood the iron  levels are usually the least of ones problems; this period thing however  is very, very sneaky! Every month one is losing just a tad bit of iron,  and although a lot of information sources are claiming that with a  balanced diet one should have replaced the missing bits by the end of  the cycle, I personally cannot confirm that. ‘Balanced’ for health  people usually means ‘utterly healthy’. 
        In my book ‘balanced’ reads as ‘mostly being a good girl, but  liking my coffees and teas and dairies’ – and those are all things that  inhibit iron to be consumed by the body. Meaning that one can eat as  much as one likes, but the body can’t use it because a lot of Chemistry  goes on between the iron and the foods and hence it is passed straight  through the intestines and does not get digested as it should be.  Additionally iron from food sources comes in all sorts if chemical  compounds and the body is rather specific about which ones it wants.  Just nibbling a rusty nail as suggested by some urban myths won’t do the  trick.
        A warning!
    Well, and then of course one has to give a warning that  too much iron can be harmful, and even if some additional intake is  indicated it may upset the stomach or cause indigestion. Hence I am  taking this little pill before I go to sleep when my stomach is not  entirely empty, but there is enough time between food and iron intake to  not have the two interfere with each other.
        My experience
    I stumbled across iron a good two decades ago. I was young, I  was healthy and I was tired down to depression. At that time I was  researching vitamins to find out if they could have a positive impact on  my allergies (which some of them have), and when I read the list of  symptoms for iron deficiency I thought I had a mirror held to my face.
        So I gave it a shot, didn’t have any side effects except of a  bit of indigestion for a couple of days until the body got used to it,  and felt an improvement instantly. After two days my energy came back  and within a week I was my old self again.
        I took a six week course as advised on the pack and then a  couple of years later I ran into the same trap. It happens so slowly  that one doesn’t realise it. Other conditions like sleep deprivation due  too much partying, work or a cold can have a similar effect and hide  the real cause. Again I took the pills  with the same outcome: Instant  relief!
        I then checked with my GP, got off the drug for a month, had  the blood levels measured which were in the lower third of the range –  so nothing bothersome or unusual – but I already felt the lack again. He  then confirmed that should I feel like needing it, I could take this  low dose continuously without causing any harm. He as well told me that  some people react to lower levels earlier than others, something that I  found confirmed in the book ‘Well-being for Women’ by Helen Lawrence (Geddes  & Grosset, 2004, p.18)
        Regarding the duration of the course it seems that my body is  telling me when enough is enough. I tend to all of a sudden forget  taking them, so I am stopping intake altogether until the next time when  I am wondering why I am so tired and if I might have caught a cold...
        Will I ever learn?
    This time round I was so proud to have survived Christmas well  and thought that this would give me a brilliant head start into summer.  Ha, I’d wished! Mid January I started feeling a bit drained, beginning  February I had my holidays when I usually slip horribly food wise – what  is ok as I am preparing for it – and after that I crushed. I didn’t  realise what was going on until mid March when the downhill trend became  more and more obvious. Within these six weeks my weight went up about 3  kg adding an additional 21,000 calories to my diet which I now have to  get rid of again. If somebody however would have dared saying a word  about my biscuit consumption, I would have gathered the last of my  strength and would have gone for a kill. There was no control  whatsoever. Now three days in I am back to my normal diet without any  problems, liking my salt less bread, the eggs and bananas.
                         Well apparently I am an iron lady in many ways!
