Important notes about thyroid disorers
1- Any sub-clinical hypothyroidism must be treated in pregnancy
2- Hyperthyroid state+ low iodine uptake = subacute thyroiditis = no need for anti thyroid drugs
3-Mild hyperthyroidism can occur is 1st trimester ( HCG behaves like TSH ) and postpartum (thyroiditis)>>> NO treatment needed .
4-Toxic nodule >>> Best treatment is radioactive iodine or surgery ( multinodular )
5- Thyroid eye disease >>> radioiodine therapy is contraindicated
6- Hyperthyroid in prgnancy >>> propylthiouraci 1st trimester and carbimazole after that
7- Hypothyroid in pregnancy >>> higher dose of thyroxine is needed
8- In all amiodarone induced thyroid disorders >>> stop amiodarone unless given for life threatening arrhythmia
9-In amiodarone inuced thyrotoxicosis + low radioiodine uptake >>>> ttt by steroids
10- In subclinical hypothyroidism + unwell patient or hypotensive >>>>> check for hypoadrenalism.
11- Thyroid eye disease may be unilateral , with normal thyroid function , or even without proptosis
