I believe that my sleep problems are related to my thyroid issues. Although I was only diagnosed about 18 months ago (Hashimoto’s), I have been having symptoms for years. My sleep "went funny" back in 2007.
I notice that the sleep seems also to be affected by hormonal fluctuations. I have just turned 50 and on a bit of a hormonal roller coaster at the moment. One of the symptoms of my PMT, for example, is that my sleep becomes particularly poor 2 or 3 nights before.
Keep telling myself that if I can achieve good hormone/thyroid balance my sleep might sort itself out. But it is achieving that wonderful equilibrium that seems so elusive!
Latest levels (as of a couple of weeks ago) were:
TSH: 0.22mu/L (0.3-5)
T4: 14.7pmol/L (11-23)
T3: 3.5pmol/L (3.9-6.8)
Take 75mcg levothyroxine a day and despite 100% compliance on my part my levels have dropped a bit since this time last year when I had just gone onto the increased dose, so don't understand what is going on there. Have been advised by a couple of people on this site that my T4 should ideally be higher (thank you for your observations, which has given me confidence to take this forward). Also need to get to the bottom of the T3 being so low. Seeing my GP Wednesday to discuss.
Had my adrenals/hormones checked Autumn 2012 and at that stage, despite the ongoing sleep problems, my cortisol was in range (behaving exactly as one would expect) though my DHEA was just below range (took a short course of DHEA but didn’t have any noticeable improvement in sleep). My melatonin also came back as being in “the optimal range”.
If there is anyone out there who has managed to sort their sleep problems through managing their thyroid/hormonal balance I would really like to hear from you.
