Brief summary
Gestational diabetes mellitus (GDM) occurs in approximately 15% of all pregnancies worldwide.GDM can lead to the development of type 2 diabetes mellitus (T2DM) later in a woman's life. Babies of mothers with GDM have a greater risk of developing T2DM and cardiovascular disease than infants of women without GDM. The degree of insulin resistance is directly proportional to the accumulated free radicals. Selenium functions as an active site component of an antioxidant enzyme, glutathione peroxidase, and helps scavenge free radicals. In addition, an experimental study has shown that selenium provides activation by binding to insulin receptors and lowers blood sugar by increasing glucose uptake by cells. According to all this information, we aimed to evaluate the effect of selenium on blood sugar regulation in pregnant patients.
Detailed description
Pregnant patients with no known chronic disease / drug use and who had an oral glucose tolerance test between 24 and 28 weeks of gestation will be included in our study. The presence of one or more of the fasting blood glucose values ≥ 92, 1st Hour ≥ 180 and 2nd Hour ≥ 153 will be considered as gestational diabetes. Our patients diagnosed with gestational diabetes in the second step will be divided into two groups. The first group will be started with diet only, the second group diet + 200 mcg selenium supplement per day. Patients will continue these treatments for 4 weeks, and at the end of 4 weeks, they will follow their fingertip blood sugar for 5 days (fasting, 1st hour satiety and 2nd hour satiety) while the treatment continues. In patients with gestational diabetes diagnosis, our targets for fingertip blood glucose follow-ups at home are fasting \<95, 1st hour \<140, 2nd hour \<120. The 5-day measurements of both groups will be averaged for fasting, 1st Hour and 2nd Hour, and it will be evaluated whether there is a significant difference in blood sugar regulation between the groups that take selenium supplements and those that do not.
