Patient: Description of condition (onset, main symptoms, hospital visited, etc.): I had my left thyroid gland and the middle part removed in May due to papillary thyroid cancer, but after the surgery, I had various indicators checked until August: triiodothyronine (1.27), TT4 (178.34), TGAb (7.8), thyroid peroxidase antibody (340). The indicators have been abnormal, all higher than normal, TSH 0.04, but the surgeon said that these indicators are immune, there is no way to return to normal Currently, I am taking Eugenol, the doctor said there is no other medicine to eat I would like to know if these indicators have an impact on health, how can I control them to normal values? Zhou Guangwen, Department of General Surgery, Shanghai Ruijin Hospital: I personally don’t think it’s necessary to take Eugenol because you only removed the left thyroid gland and the right thyroid gland, so taking Eugenol won’t have a therapeutic effect. Patient: If you don’t take Eugenol, the TSH index will be very high, and these indicators are not normal, please tell you the reason, thank you Shanghai Ruijin Hospital General Surgery Department Zhou Guangwen: I think the most critical is that FT4 should not exceed the normal value range.
