The effect of different periods of fasting on oral glucose tolerance was investigated in 33 subjects. It was found that glucose tolerance deteriorated as the fasting period became shorter. This effect was seen almost exclusively in subjects over 40 years of age. Only the fasting blood sugar was affected by the duration of the pretest fast in younger subjects.

Thyroid function in haemochromatosis.

BACKGROUND: In hereditary haemochromatosis (HH), the thyroid gland is the site of substantial iron deposition. However, there have been relatively few reported cases of thyroid dysfunction in HH. AIM: To evaluate the prevalence of thyroid disorders in a large group of patients with HH. METHODS: A variety of endocrine investigations were undertaken including thyroid function tests and thyroid antibody studies. RESULTS: A total of 154 consecutive patients (123 male, 31 female) were studied. One case of primary hypothyroidism was identified, giving a prevalence of 0.6%. Subclinical hypothyroidism was identified in two females, giving a prevalence of 1.3%. Iatrogenic hypothyroidism was identified in two other cases. No case of hyperthyroidism was identified. CONCLUSION: Thyroid dysfunction is an uncommon occurrence in patients with HH.
