A 42-year-old patient presented with complaints of thyroid gland enlargement, weakness, sleepiness, and dry skin. EAF readings below normal were determined on points of the thyroid, intestines, and lungs. On all other points, they were within normal limits. No emitters were found to normalize thyroid function when directly applied. When the GI emitter was applied to the lung area, normalization of readings was observed at both lung and thyroid points. This fact indicates a reduction in the compensatory function of the thyroid due to the pathological process in the lungs.
