My daughter is 18. I first requested blood tests with the GP when she was 15. This was during covid. I had to fight over the phone for them but she'd put on weight rapidly, she especially looked to be retaining fluid in her legs, feet, hands and face. Other symptoms = tiredness, slow movements, dry eyes, dry coarse hair, often cold when no-one else is, low mood, anxiety, heavy and irregular and painful periods. Blood tests came back okay and there was no follow-up and we spent a few years considering other things, PCOS, low iron, low folate, allergies etc...
Last year, at age 17, we pushed again for her thyroid to be tested, as she'd continued to put on weight despite a super healthy diet and a year of going to the gym. The results were:
TSH 1.17
T4 16.2
3 months later I arranged for private blood tests so I could also get her antibodies tested as I still suspected her thyroid was an issue. Results below all deemed in normal range:
Ferritin 25.8 (13 - 150 μg/L)
Vitamin D (25 OH) 53 (50 - 200 nmol/L)
TSH 2.38 (0.27 - 4.20 mU/L)
Free T3 6.0 (3.1 - 6.8 pmol/L)
T4 Total 88.8 (66 - 181 nmol/L)
Free T4 14.2 (12.0 - 22.0 pmol/L)
Serum Folate L 7.13 (8.83 - 60.8 nmol/L)
Vitamin B12 327 ((145 - 569 pmol/L)
Magnesium 0.82 (0.7 - 0.91 mmol/L)
IMMUNOLOGY
Anti-Thyroidperoxidase abs 14.7 (<34 IU/mL)
Anti-Thyroglobulin Abs 12 (<115 IU/mL)
She's been taking supplements to raise her ferritin and folate, vitamin D etc... 5 months later we repeated at home private blood tests . Results:
* Vitamin D (25 OH) 59 (50 - 200 nmol/L)
* Magnesium 0.84 (0.7 - 0.91 mmol/L)
* Ferritin 53.00 (13 - 150 μg/L)
* Serum Folate 15.70 (8.83 - 60.8 nmol/L)
* Active B12 63 (37.5 - 150 pmol/L)
* TSH 3.55 (0.27 - 4.20 mIU/L)
* Free T4 14.2 (12.0 - 22.0 pmol/L)
* Free T3 5.4 (3.1 - 6.8 pmol/L)
* T4 Total 86.1 (66 - 181 nmol/L)
* Anti-Thyroglobulin Abs 15 (<115 IU/mL)
* Anti-Thyroidperoxidase abs 18.1 (<34 IU/mLTSH 2.38)
So, my thoughts and questions because I am confused what to do next, if anything.
I've read a study which says normal TSH range for females aged 18-29 might be closer to TSH 04 - 2.5. So, my daughter's TSH is now beyond normal range. I've also read a study which says the presence of positive antibodies means the person will go on to develop autoimmune hypothyroidism. And also read a study which says all of the population have low antibodies and only a small percent will go on to develop an autoimmune condition!
The bottom line for me is that her TSH is going up. Two members of our family recently were diagnosed with coeliac disease so now we have evidence of autoimmune disease in our family. But I am guessing a GP is going to turn us away and do nothing. Still, she has symptoms. All the same symptoms and has done so for at least 3-4 years. And these are making her miserable. Each year we are having to buy her new clothes as she gets bigger. She's just never energetic, despite the very healthy food. She's a young adult who should be enjoying life.
I wonder if she didn't already practice a very healthy lifestyle whether her numbers would be higher? Or are her numbers just normal and what are found in the general population. By contrast, my thyroid was measured this year and last and my TSH was 0.48 and 0.95 respectively. If we went private, would anyone do anything? Is it even worth seeing our GP just to log with them we've had further blood tests for future reference?
