Hello! I went for a blood test yesterday and the surgery called me today and said I need to go back for another one because I was dehydrated so they couldn’t use the results. I don’t understand this because I drink so much water all the time, some days I will drink 4 litres, not because I’m particularly thirsty but I know it’s good for me and I like it, plus it stops me snacking too much. I had drunk almost a litre that morning before the blood was drawn at 9am. Has anyone had this happen before? Now I’m worried that there’s something else wrong that’s causing what the dr thinks are inaccurate results, anyone any idea what could be going on?? Thank you if anyone can help!
