Hi everyone - I'm just over 12 weeks pregnant and my TSH level is currently 2.2 and FT4 is 15.4, however I'm very worried as my TPO antibodies have come back as 184 (lab range max is 60) and TG antibodies are 413.2 (maximum for lab is 20). I had my 12 week scan and thankfully things look to be fine but I feel so concerned regarding my antibody results, I don't understand why they are so terribly high and I'm worried about the effect possibly on my pregnancy. I was very poorly last year and my weight fell to 38kg (I'm now still a little underweight at 46.8kg) and my BMI is 17.3. I was diagnosed as coeliac last year and have also become lactose and egg intolerant and am avoiding gluten, milk products and eggs. I am also being re-tested for inflammatory bowel disease / Crohn's. I don't know why my body has launched such an attack but if anyone can shed any light I'd be hugely grateful. As a side note, after the birth of my last child in November 2011 I was diagnosed with a form of chronic anxiety / ptsd as the birth was very difficult and had left me with health problems, and in my mind I'm sure this has had a huge effect on my body. I do not have 'typical' hypothyroid symptoms although I do have some hair less and feel the cold, but then I am underweight. My TSH had been holding steady around 3 before I fell pregnant on a dose of only 25 micrograms per day, but unfortunately I've now also developed a possible intolerance to the fillers in the my levothyroxine and am going to start liquid levo instead. Thank you for your help.
