甲状腺机能减退(甲减)是常见内分泌病,成人女性和男性患病率分别为1.4%和0.1%。甲减的特征临床症状与体征包括怕冷、皮肤干燥、虚肿、便秘、声嘶、头发干燥、指甲易于脆裂、外周非凹陷性水肿、心动过缓以及跟腱反射松驰延缓等。测定血清 T_4、TSH 水平诊断不难确定。然而,不典型甲减病例可能以某些不常见的症状作为突出表现或其出现先于典型症状,因而可能作出错误诊断,并对病人带来潜在的严重后果。 Hypothyroidism (hypothyroidism) is a common endocrine disease with a prevalence of 1.4% and 0.1% for both adult women and men. Hypothyroidism clinical symptoms and signs include cold, dry skin, constipation, constipation, hoarseness, dry hair, nails vulnerable to embrittlement, peripheral non-pitting edema, bradycardia and Achilles tendon reflex relaxation delay. Determination of serum T_4, TSH level diagnosis is not difficult to determine. However, cases of atypical hypothyroidism may highlight some uncommon symptoms or their appearance precede typical symptoms and may therefore result in misdiagnosis and potentially serious consequences for the patient.
