In this paper we have studied an effect of blood glucose concentration on the absorption and reflection spectra of blood components in the frequency range of 0.05÷2.7THz. The observed differences in the experimental spectra were compared with the dielectric function of water in order to identify the parameter that makes the greatest contribution to the change in the dielectric function of sample. It was obtained that the changes of impact of the first Debye term describing «slow» relaxation of water molecules are associated with variations in the glucose concentration in blood samples.
