These mechanisms further activate the hypothalamic-pituitary-adrenal axis, hepatic glycogenolysis, hyperglycemia, hyperlipidemia, and insulin resistance, contributing to core depressive features of anhedonia, emotional dysregulation, and cognitive slowing ( The complex etiopathogenesis of T2DM has been explored in detail and includes insulin resistance (in the liver, muscles, and adipose tissue), impaired insulin secretion, -cell dysfunction, immune dysregulation and meta-inflammation, hyperglucagonemia, disrupted gut microbiota, increased gastric glucose absorption, renal adaptation with enhanced glucose reabsorption and gluconeogenesis, decreased dopamine, and heightened sympathetic tone in the brain ( via cells of the circumventricular organs located around the third and fourth brain ventricles, transmitting signals to deeper brain structures

It has been shown that being deficient in any of these key minerals can result in both weakened antibody and immune responses to illnesses and diseases
Our study suggested that using GLP-1 RAs will inhibit the initiation of DR among patients with diabetes, mainly background and nonproliferative DR, which could be recommended to use as a first-line treatment to prevent DR
