Hello, I am new to this group. I went to a hormone specialist last year when my menopausal symptoms were giving me grief. I was prescribed progesterone, Estridot patch and DHEA as well as cytomel, which I've been taking for the past 1.5 years. In November, my doctor increased my dosage from one 5 mcg tab to two 5 mcg tabs/day. This was due to my still having hypothyroid symptoms, mainly awful fatigue, inability to lose weight, thinning hair and cold hands and feet. Neither my weight nor fatigue improved much after the increase in Cytomel. In January of this year, I went for a sleep test which revealed that I have severe silent (non-snoring) sleep apnea (30 apneas/hour). My GP was shocked as I did not fit the profile. I started on CPAP therapy mid-February and have been feeling a lot better. With sleep apnea, your body isn't able to go into deep restorative sleep. From what I understand, when you stop breathing, your reduced oxygen level causes your body to increase your cortisol levels which elevates your heart rate - so you wake up enough to gasp for air. All of these sleep interruptions do not produce a restful sleep and your hormones do not balance, your body doesn't regenerate the way it should. This would explain a lot of my symptoms with fatigue, weight gain and adrenal fatigue (my adrenals didn't have a chance to heal) and general hormone issues. It has taken a while to adapt to the CPAP and get my pressure levels comfortable, but effective. I do feel like I am getting proper rest now.
So my main concern is, that I have had extreme anxiety, with heart palpitations, over the past month and have had two work stress related panic attacks. I am an anxiety prone person, but I have never before had a panic attack, so I believe it must be related to my thyroid levels changing from my now restorative sleep, which is reducing my need for the cytomel. I didn't take any cytomel over the weekend and my symptoms were much better. I took one tablet this am, while I don't feel anxious, my heart palpitations are back. Thankfully, I have a blood test this week and an appointment with the hormone doctor next week. Has anyone else in the group had issues with anxiety linked to taking cytomel?
