Modern studies show that it is the transit microflora, the percentage of which is negligible compared to the total volume of the intestinal microbiota, that can cause severe damage and cause the appearance of chronic and acute diseases not only of the intestines but also of the immune, nervous, endocrine systems, etc. Instead, the obligate intestinal microbiota and even the opportunistic microbiota exhibit a number of beneficial properties, ranging from the synthesis of short-chain fatty acids, butyrate, and acetate to promoting the synthesis of vitamins and hormones such as dopamine, serotonin, etc. At the same time, the adverse effects of the gut microbiota cannot be discounted.
The aim. The study aims to find correlations between gut microbiota, body mass index, and age in patients with type 2 diabetes and thyroid dysfunction..\
Materials and methods. The study included 84 patients with type 2 diabetes, obesity, and thyroid dysfunction. To analyze the composition of the intestinal microbiota, fecal samples were taken, and the quantitative and qualitative composition was calculated using the principle of PCR sequencing. Statistical methods of comparison and correlation of variables were used.
Results. In patients, several significant correlations were found between the gut microbiota and the parameters studied. A negative correlation was found between body mass index and Bifidobacterium spp. and Escherichia coli, and a positive correlation was found between body mass index and some opportunistic pathogens. Thus, with Shigella spp. and Staphylococcus aureus, there is a direct weak reliable relationship, while an inverse reliable relationship with Helicobacter pylori. Interesting correlations were found with a tendency to confidence with Salmonella spp. and Bacteroides thetaiotaomicron direct weak and a tendency to probable feedback between BMI and Faecalibacterium prausnitzii and Candida spp.
Conclusion. We found that body mass index has a greater impact on the gut microbiota than age. Also, the data obtained indicate that obesity negatively affects the number of some beneficial bacteria. We can assume that, like metformin, one of the most common drugs for the treatment of type 2 diabetes mellitus, it can affect the composition of the intestinal microbiota
