It was shown the modern data on the study of the risk factors which contribute to the formation of osseous tissue structural and functional disorders at the diffuse toxic goiter (DTG) patients and evaluation of the bone tissue metabolism. At the surveyed reproductive age women with DTG the bone disorders set up to 57.47 % (osteopenia — 54 %, osteoporosis — 46 %). As the result of the research it was proved the necessity of densitomertic examination for DTG patients, especially T-point determination which indicates early character of osteoporotic disorders at DTG.
