What does a blood cortisol level of 563 nmol mean? I had Crainiopharyngioma as a child and have symptoms which are getting worse over the years such as extreme tiredness, light headedness, back ache, tummy ache, ibs , shakes. I wondered if the bit of the tumour that was left might be causing my pituitary gland to produce extra cortisol?
Hi, Cortisol levels have diurnal variation - meaning the levels of hormone vary according to the time of test. Presuming the test was done early in the morning cortisol level of 563 MOL is in limits.  If rest of the hormones are within limits, then craniopharyngioma has no direct relations with your current symptoms. Discuss with an endocrinologist who can get rest of the hormone assay done to rule out endocrinopathies. Hope this answers your query. Regards
