Experts have advised against hormone treatment in adults with mild thyroid problems. Their strong recommendation against hormone treatment is based on new evidence that it does not improve quality of life or symptoms including low mood and fatigue.

‘The strong recommendation against hormone treatment for adults with mild thyroid problems is based on new evidence that it does not improve quality of life or symptoms including low mood and fatigue.’

Subclinical hypothyroidism (SCH) occurs when the thyroid stimulating hormone (TSH) levels in the bloodstream are slightly raised, while the level of thyroid hormone remains normal. 




It affects up to about 5% of the adult population, but 10-15% of the elderly. While some people have no symptoms at all, others can show mild signs of fatigue, low mood and weight gain, which may or may not be related to the condition.
Subclinical hypothyroidism can only be detected by a blood test. In the UK, about 25% of adults have thyroid function tests every year and guidelines tend to recommend hormones for those with TSH levels above 10 mIU/L (a normal TSH level is 0.4 to 4.0 mIU/L).
Research shows that hormone treatment for SCH has doubled from 1996 to 2006.
So an international panel of clinicians and patients with SCH used a recent detailed analysis of the latest evidence (a systematic review of 21 trials and about 2,200 participants comparing the effects of thyroid hormone treatment with no treatment or placebo in adults with SCH) to develop recommendations for clinical practice.

What's more, they say taking a pill and attending lifelong check-ups is burdensome, and they cannot rule out the possibility of harms.

The recommendation does not apply to women who are trying to become pregnant or patients with particularly high TSH levels (above 20 mIU/L). It may also not apply to patients with severe symptoms or some aged under 30.
Future research could explore whether there is an unidentified group of patients who might benefit from treatment, say the authors.
In the meantime, if implemented, this recommendation "may substantially alter prescribing trends" they conclude.
