Seasonality of thyrotoxicosis.
Study of a large and representative series of thyrotoxic patients showed a higher frequency of diagnosis in the spring and summer. The median interval between onset and diagnosis was 12 weeks, indicating a peak in onset of the disease from January to June. The seasonality of thyrotoxicosis may be related to seasonal variations in iodine intake.
