title: Birmingham Medical Research Expeditionary Society 1977 Expediton: thyroid function and acute mountain sickenss.
abstract: In a study of 17 subjects plasma-thyroxine-binding globulin and plasma thyroxine concentrations rose during a high altitude trek. An early and sustained rise in plasma reverse triiodothyronine occurred independently of changes in plasma thyroxine and was probably related to physical exertion. Similar changes in thyroid function were found in subjects most affected and least affected by acute mountain sickness.
