Dehydration

I drink a lot, in comparison with most people. However much I drink it is clearly not nearly enough.

I know that Kadcyla is very dehydrating. Many of the side effects, headache, constipation, dry, cracked hands and feet, can all be attributed to dehydration. I seem to have a near permanent dry mouth, which is why I drink a lot of water. When I went out for dinner a couple of weeks ago, I must have drunk about a litre and a half of water, when I got home much later that evening, having not availed myself of the restaurant facilities, I went to the loo and probably only peed out about a teacupful. Clearly I am suffering from chronic dehydration.

I went for my regular blood test prior to treatment and knowing that I was probably a bit dehydrated, I made a special effort to drink even more. The first nurse, (who now is a member of the "she could stick a Bic biro in my vein and I wouldn't notice" club), made two attempts, found lovely veins but no blood. The protocol in the chemo unit is the nurse gets two attempts and then has to call a colleague for further attempts. Not sure what happens if the second nurse has to have two attempts as, fortunately this has never happened. The second nurse accesses the vein near the base of my thumb, which is possibly my least favourite site, with little or no pain. She gets enough blood and then removes the needle. It was without doubt the most painful needle removal ever. In fact it is the only time that a needle removal has hurt. I can only describe it as a sort of bruise like feeling. Furthermore, the pain continued for about another 15 minutes.

I mention this to the great oracle that is Facebook and the general consensus is that the pain is down to being dehydrated. I realise that I am going to have to up my fluid intake by industrial proportions.

The next day is treatment day. Before I leave the house I have probably drunk about  pints of water and fruit tea. I consume a further couple of pints of water and fruit juice whilst being treated. When I get home I continue to drink more and more water. It is only by about 9pm that my mouth stops feeling dry. Hooray! There is, naturally, a slight downside to all this drinking, many nocturnal visits to the loo.

So I will continue to drink a couple of lakefuls of water and see what happens next time I go for my blood test.
