Patient: Description (onset, main symptoms, hospital visited, etc.): I didn’t know I had hypothyroidism before I got pregnant, but in June 2010 I got pregnant and had brown discharge at 8 weeks. He was born by cesarean section at 41 weeks, weighing 4200 g and measuring 54 cm. Cord blood results at birth: serum thyrotropin 14 reference value 0.27-4.2 high serum total T3 0.81 reference value 1.3-3.1 low serum total T4 131.1 reference value 66-181 serum free T3 2.15 reference value 3.1-6.8 low serum free T4 16.9 reference value 12-22 heel blood taken three days after birth, TSH was 7.06 and passed. The screening center did not call me. On the fourth day of life, I had thigh blood taken at the hospital, but the values differed greatly from the heel blood: serum thyrotropin 20.57 reference 0.27-4.2 high serum total T3 1.93 reference 1.3-3.1 serum total T4 181 reference 66-181 serum free T3 5.38 reference 3.1-6.8 serum free T4 24.48 reference 12-22 high went to the hospital The doctor said it was better than last time, but I didn’t see what was better, and it was very different from the screening results. I have been mixed feeding all this time, and when the child was full term, scalp blood was taken for testing: Thyroglobulin antibody 6 Ref. 0-34 Anti-thyroid peroxidase antibody 62.7 Ref. 0-12 High serum free T3 5.77 Ref. 4.5-7.3 Serum free T4 14.5 Ref. 10.8-20 Serum thyroid stimulating hormone 4.1 Ref. 0.8-5 Anti-T3 74.2 Reference values 32.5-66.4 High At the 46-day checkup, the child weighed 6300 g and was 58.2 cm long. The amount of milk is around 800 ml per day. He has been having two to three stools per day, but this week he started having stools once a day or once every two days. Sometimes my baby likes to turn his tongue in his mouth when he is awake and playing. Now that I have stopped breastfeeding, would it be better for my child. Anxious mother. Doctor, is this a problem for your child? Now that I have stopped breastfeeding, would it be better for my child.

Sometimes my baby likes to turn his tongue in his mouth when he is awake and playing. Now that I have stopped breastfeeding, would it be better for my child. Anxious mom. A: Anti-thyroid peroxidase antibody 62.7 Ref. 0-12 high, related to your genetics, last serum free T3 5.77 Ref. 4.5-7.3 Serum free T4 14.5 Ref. 10.8-20 Serum thyroid stimulating hormone 4.1 Ref. 0.8-5 all normal. It is more likely that the child will have low thyroid in the future, but for now it is normal. Can I ask you again? The results are as follows: Thyroglobulin Antibody 3 Ref. 0-34 Anti-Thyroid Peroxidase Antibody 39.4 Ref. 0-12 High Serum Total T3 2.5 Ref. 1.84-3.24 Serum Free T3 6.26 Ref. 4.5-7.3 Serum Total T4 89.7 Ref. 82.3-167 Serum Free T4 13.4 Ref. 10.8-20 Serum thyroid stimulating hormone 3.5 Reference value 0.8-5 Among them, the anti-thyroid peroxidase antibody 39.4 is more than 20 points lower than a month ago, is this antibody being metabolized slowly and will it all be metabolized eventually? I see that the total T4 is below the normal range, does this have any effect? Thank you, doctor. A: Your antibodies are high, which means you probably have Hashimoto’s thyroiditis, a disease whose genes are passed on to children, who are also prone to this disease when their immune function is disrupted. The incidence is higher in girls. The onset of the disease is usually during adolescence. The child’s antibody production is self-generated and can be high or low. It is recommended to check the child’s nail function every 3 months during the first year of life. If it is normal, it can be checked once every six months in the future, or at any time according to the symptoms. This disease is not a serious disease, and as long as the nail function is normal, the child can grow and develop normally, and the adults can live normally. Patient: Thank you. So the child does not need any treatment at the moment, right? Patient: Doctor, thank you very much for your reply. I would also like to ask, can the child be vaccinated every month now that he has antibodies? Thank you. The antibodies will gradually turn negative (the antibodies of the newly born child are transmitted from your fetus), and it is recommended that the child be negative before vaccination. Patient: I see, thank you very much
