This article studies the morphometric changes observed in the wall of the ventricles of the heart of offspring born to parents with diabetes. In the experimental study, the structure of cardiac cardiomyocyte cells, capillary network, and myocardium was analyzed. According to the results, thickening of the heart wall, cardiomyocyte hypertrophy, and an increase in the amount of interstitial connective tissue were detected in diabetic offspring. These changes were evaluated as early morphological signs of functional disorders in the heart. The results of the experimental study can serve as a scientific and practical basis for studying the effect of diabetes on the structure of the heart of offspring based on in-depth scientific results and developing measures to eliminate the complications and consequences of maternal diabetes in the heart of the offspring.

Diabetes in the mother causes inflammatory-dystrophic changes in the vascular-tissue structures of the small intestine of the offspring born from them. Morphofunctional disorders in blood vessels play a leading role on the basis of pathomorphological disorders in the small intestine. These processes lead to trophic disturbances, dystrophic and degenerative changes in intestinal tissue structures in the late periods of postnatal ontogenesis.

Diabetes mellitus in the mother causes inflammatory-dystrophic changes in the vascular-tissue structures of the ovaries during the postnatal ontogeny of the offspring born from them. Pathomorpho-functional disorders in the internal vessels feeding the egg are the basis of the morphological disorders in the ovaries of the offspring. These processes lead to trophic disturbances, dystrophic and degenerative changes in tissue structures of the reproductive azo-ovaries in the late stages of the postnatal ontogeny of the offspring.
