Why do any patients think that they are entitled to see any results until these have been discussed? I would no more think to access mine than fly to the moon, because in the main, blood test results in particular are difficult to analyse.
GPs can charge a patient if they access results at times other than when discussing them.
Did the Colorectal Surgeon suggest to your GP that you should be prescribed higher strength tablets, that would be my first concern. That something was told to me 'over the bed' but not acted upon, i.e. not being told that he/she would write to the GP about the findings. This mayB something to bring up at your appt.. Often in the heat of the moment patients won't think to ask, it's the brain whirring that makes a person worry.
Fear of dying is normal 4 many. I fear being left in pain ........ regardless of what hospice workers suggest people are not always treated symptomatically but 'U can't have any more for 4 hours'-type suggestions. Instead of being treated as is ......... some people fear being interned ........ this not unusual.
Fear/phobias can take over completely, mine was day and night when I would dream about it ......... I avoided situations where 'it' might happen in front of me

If the results showed anything untoward you wouldn't be waiting until Tuesday, some1 would have been on the 'phone to you with advice. As for taking OTC extra iron ..... will U B telling your GP at your appt.? As for lowering your cholesterol, DH and I were prescribed statins to be certain that we remain well. MayB make a list of queries to take to the appt.? And let us know how you get on.
