A 50-year-old patient presented with complaints of thyroid gland enlargement. EAF readings on thyroid and lung points were below normal. Only lung points tested positive for infection and disease nosodes. Testing determined that normalization of thyroid readings was achieved by applying an emitter to the lung area. This is explained by the fact that a disease in the lungs led to thyroid functional disturbances. Due to compensatory functions necessary for normal body functioning, the thyroid became overloaded, which was reflected in the below-normal EAF readings.
