The еffects of low mineral content water on microbiota, metabolic, and oxidative stress parameters in patients with type 2 diabetes mellitus

Although scientific evidence has shown that natural mineral waters have potential beneficial metabolic effects, there is still very scarce data on their influence on type 2 diabetes mellitus (T2DM). The study was designed to investigate the effects of low mineral water from the "Sneznik-1/79″ source in Serbia on microbiota, metabolic, and oxidative stress parameters in patients with T2DM. In total, 60 patients with confirmed T2DM were included in the study, and they consumed "Sneznik-1/79″ water for 28 days. To examine the positive effects of "Sneznik-1/79″ water, we compared the results before and after the four weeks of "Sneznik-1/79″ water intake. Standard biochemical analyses were carried out, such as glucose level, lipid profile, and stool tests. The blood samples were collected to evaluate the effects of "Sneznik-1/79″ water on the redox status. At the end of the monitoring period, the total cholesterol concentration significantly dropped compared to the initial value. A significant improvement in intestinal peristalsis was observed, which was reflected in the fact that after four weeks, all patients established regular, daily bowel movements. Moreover, consumption of "Sneznik-1/79″ water eliminated the appearance of dysbiosis in 50% of patients. Additionally, the antioxidant capacity was improved by increasing the concentration of superoxide dismutase and reduced glutathione. The result of our study pointed out that the intake of "Sneznik-1/79″ water could be a promising adjuvant therapy for improving intestinal peristalsis as well as reducing the appearance of dysbiosis in T2DM patients.
