Lucozade in replacing lost fluids.

    Hi there,

    I was drinking a bottle of lucozade this morning when I noticed the warning on the bottom of the bottle telling me not that lucozade was not suitable to replace the fluids lost during diorehhea (sp?). I was curious as to why this was the case?

    I thought that during times of extreme dehydration a solution of glucose and electrolytes was administered to a patient? Why not lucozade? Is it because lucozade is hypertonic relative to your cells and would only cause further water loss? I'm really curious as I can't figure this out for the life of me.

    Thanks!
    Bobby

    When you want to put some fluid into a cell, you want to make sure that the area outside the cell has less electrolyte than inside the cell. water is in high concentration in the extracellular fluid and will shift into the cell to relieve the imbalance. This is hypotonic fluid therapy.

    When you put a lot of electrolyte into the extra cellular fluid, water must actually come out of the cell and go into the extra cellular fluid to satisfy its requirements. Water follows electrolyte. That's hypertonic fluid therapy. The cell will shrivel up. You wouldn't want that in a case of dehydration!

    Lucozade is hypertonic as it is loaded with carbs. It isn't really intended for dehydration.

    Plus I think the main reason is that lucozade (except lucozade sport and citrus I think) contains caffeine.

    Caffeine is a diuretic i.e. it makes you pee a lot and thus actually will make you lose more fluid than you take in and thus dehydrate you further.


    Funny that they dont mention this hey? I guess thats marketing for ya tho.
