七、结论
亚临床甲减是很常见的疾病，尤其在老年女性中。对于血清TSH水平超过10mIU/L的患者是需要治疗的，其治疗的目的是要预防进一步的发展为临床甲减。对于年龄校正后血清TSH水平在正常值的97.5%以上，或是血清TPOAb高水平的患者，治疗可能会阻止和延缓临床甲减发生，改善脂代谢异常和心血管功能指标，但尚不清楚是否可以降低心血管疾病的发生风险。对于血清TSH水平小于10mIU/L的患者的治疗是否可以改善其认知和临床症状，尚没有足够证据加以证明。对于老年人，治疗时可能产生包括心肌缺血和心律失常的风险[47]，亟须日后设计更完善的实验来加以评估。对于妊娠早期亚临床甲减患者推荐进行甲状腺激素治疗。年轻人在不考虑治疗费用的前提下，也应该进行治疗。
