"An unwelcome challenge to this view is the proportion of hypothyroid patients that report that they are not back to their normal self despite doses of thyroxine sufficient to normalise TSH levels (1,2,3,4,5). We recently tried to quantify this problem in a community-based cross-sectional survey and observed a 6.7% absolute excess of psychiatric caseness (32.3 vs 25.6%) in patients on thyroxine compared to an age- and sex-matched control population from the same community. This difference persisted even in individuals on T4 with recent TSH levels in the laboratory reference range (6)."
Egentlig et bevis for at levothyroxin ikke virker bra. de har jo ikke prøvd Thyroid (For eksempel merkenavnet Armour eller nature-throid eller lign)
