This is my first post to this excellent website, and I hope someone can help me understand my first private blood test - fasting, last levothyroxine 26 hours previously. No B12 supplement for three weeks prior to the test. I did find it difficult to get sufficient blood, this being my second attempt. I started before 9am but it was almost 9.30am by the time I finished!
My brief history is that I have had hypothyroidism for about 23 years, and for most of the time since 2008 I have taken the same medication - 50mcg levothyroxine and 20mcg liothyronine sodium. I have always been very tired and cold, weight gain, brain fog, constipation, dry skin, hair loss etc. My NHS TSH and T4 tests are always in range, with “Normal. No further action needed” results.
In 2013 I started with Paroxysmal Atrial Fibrillation, which progressively got worse - longer periods and more frequent occurrences of AF – until it ruled my life. I felt terrible with no quality of life. In June 2023 I had a cryoablation, which has been successful. Great! I did spend a week in hospital just after the op with pericarditis, and whilst I was there, a cardiologist stopped the T3 and increased the T4 to 75mcg. He didn’t consult me or tell me about the change. Since then my symptoms have worsened – I can’t sleep, and some days I am just so tired I can’t do anything. Most nights I have bad cramp in my lower legs and feet. All my joints ache and I have a flare up of Polymyalgia Rheumatica in my upper arms. Weight 68 kg.
I had an appointment with an NHS endo in December. He didn’t consider my symptoms at all, just looked at my test results and said I was on the correct dose of medication and discharged me. The last thing I want is for PAF to start again, but I really feel I need a higher dose of thyroxine. I feel so depressed some days.
