We have just submitted this paper and hope to get it published in due course. It deals with subclinical hyperthyroidism after treatment of toxic goitre and comparing with nontoxic conditions and controls. We think it is the right way to go about assessing a subclinical state and the procedures to use to regain "health"..

Effect of Radioiodine Treatment on Quality of Life in Patients with Subclinical Hyperthyroidism: A Prospective Controlled Study

 Rudolf Hoermann1, John E. M. Midgley2, Johannes W. Dietrich3-6, Rolf Larisch7

Abstract 

Background. Radioiodine treatment (RIT) has a high success rate in both the treatment of hyperthyroidism and improving the quality of life (QoL) of symptomatic patients. In asymptomatic patients with subclinical hyperthyroidism thyroid related QoL outcomes are less well known. 

Purpose. Study aim was to evaluate thyroid-related QoL in patients with subclinical hyperthyroidism mostly due to toxic nodular goitre undergoing RIT, compared to a control group of patients with euthyroid non-toxic nodular goitre.

 Methods. Study design was monocentric, prospective, controlled. Fifty control subjects were enrolled and 51 RIT patients. Most subjects were examined at least twice at an interval of 6 months, with visits immediately before and 6 months after treatment in the RIT group. QoL was estimated with the ThyPRO questionnaire, using its composite scale as primary outcome. Treatment effect is the mean adjusted difference (MAD) between groups over time, using repeated‐measures mixed‐effects models. 

Results. TSH concentrations were significantly lower in the RIT group prior to treatment and recovered thereafter slightly above the level of the control group. Correspondingly, composite ThyPRO scale improved significantly after 6 months from a worse level in the RIT group, compared to controls (MAD -10.3 [95% CI -14.9, -5.7], p<0.001). QoL improvements were strong for general items, but less pronounced for the hyperthyroid domain. Compared to controls, thyroid volume, thyroid functional capacity (SPINA-GT) and deiodinase activity (SPINA-GD) were significantly reduced in the RIT group.

 Conclusion. Patients with subclinical hyperthyroidism improve both biochemically and in their QoL after RIT, compared to controls. QoL assessment should have a wider role in clinical practice to complement biochemical tests and help with treatment decisions.

Thanks for this! I think it's going to be very helpful for people with subclinical hyperthyroidism who are current being left to get on with their symptoms alone.
