Questions in the Category: Adrenal Glands
Test: Synacthen
A blood test has shown that I have a low level of the hormone cortisol. As a result I am now being referred to hospital to have a synacthen test to assess my adrenal gland function. As this test involves the use of a drug that stimulates steroid production is it likely to cause any problems for someone with ME/CFS? Or could the use of a steroid be a way of treating ME/CFS?
Low sodium levels – Hyponatraemia
I’ve been feeling generally unwell and more fatigued – mentally and physically, for the past few months.
My GP ordered some routine blood tests – all of which were normal apart from having a slightly lower than normal level of sodium in the blood. My GP isn’t too concerned and is going to repeat the blood test. Could a low sodium level be caused by having ME?
Addison's Disease
I was interested to see the item on Addison’s disease in the Winter issue of ME Essential as I have a close friend with this rare disease and it obviously has some interesting symptom overlaps with ME/CFS. So is there any evidence that adrenal gland failure, and steroid hormone production, could also be involved in ME/CFS? If so, would it be worth looking at steroids as a possible form of treatment for ME/CFS?
Treatments: Drugs – Sensitivities & Side-effects
This is more of a warning than a question. Earlier this year I experienced a rapid and noticeable deterioration in the fatigue part of my ME/CFS. I was also getting muscle cramps – a new symptom to add to the list. All of this coincided with a prescription from my doctor for water losing tablets (diuretics) to treat high blood pressure. At first, she didn’t think there was any connection. But after doing some blood tests it turned out that I had a low level of potassium – something that can occur as a side-effect of using this type of drug. After a change in medication, my potassium level returned to normal and my ME/CFS symptoms also improved. So it’s worth noting that drugs can sometimes cause a significant exacerbation of symptoms for people with ME/CFS.
Stress and ME/CFS
When I first developed ME, this was triggered by an infection. But I was also under a lot of physical stress (at work) and mental stress (at home) at the time. I know that ME isn't just another type of stress disorder but stress does seem to play a role in both triggering and causing exacerbations in some people with ME. So what do we know about the role of stress in ME? And has there been any research into the role of stress?
