    How metformin works for insulin resistance


    Polycystic Ovarian Syndrome, or PCOS, and Insulin Resistance (IR) often occur simultaneously. While the connection between these two conditions is, as of yet, not entirely clear, researchers have determined that IR can lead to PCOS and diabetes. Although Metformin claims to reduce IR, current labeling laws do not require pharmaceutical companies to reveal how their products achieve results, they simply must accurately represent what kind of results can be expected from their medications., a blog that reviews diabetes medications and treatment options, has published some interesting findings pertaining to how Metformin actually improves diabetes and PCOS. A study conducted on mice has suggested that the drug lowers blood sugar not by reducing IR, but by activating a gene that does not function properly. This gene, which is located in the liver, stops the production of glucose. According to the findings of this study, this pharmaceutical works on a deeper level than simply increasing the sensitivity of the body’s cells to insulin—it actually addresses a genetic issue. While the end result remains the same, blood sugar is lowered; the cells of the body are no more sensitive to insulin than they were before. Insulin resistance, defined as the inability of insulin to exert a normal biological action at the level of its target tissues, is one of the principal pathogenetic defects of type 2 diabetes. Metformin, the most widely-prescribed insulin-sensitizing agent in current clinical use, improves blood glucose control mainly by improving insulin-mediated suppression of hepatic glucose production, and by enhancing insulin-stimulated glucose disposal in skeletal muscle. Experimental studies show that metformin-mediated improvements in insulin sensitivity may be associated with several mechanisms, including increased insulin receptor tyrosine kinase activity, enhanced glycogen synthesis, and an increase in the recruitment and activity of GLUT4 glucose transporters. In adipose tissue, metformin promotes the re-esterification of free fatty acids and inhibits lipolysis, which may indirectly improve insulin sensitivity through reduced lipotoxicity. The improved glycaemia with metformin is not associated with increased circulating levels of insulin, and the risk of hypoglycaemia with metformin is minimal. The therapeutic profile of metformin supports its use for the control of blood glucose, in diabetic patients and for the prevention of diabetes in subjects with impaired glucose tolerance. Moreover, the improvement by metformin of cardiovascular risk factors associated with the dysmetabolic syndrome may account for the significant improvements in macrovascular outcomes observed in the UK Prospective Diabetes Study.

    The use of metformin in people with diabetes appears to favorably alter their gut microbiome, resulting in an improved glucose metabolism. The primary effect of metformin aims to stimulate levels of certain bacteria to enrich the microbiota milieu,and several butyrate-producing bacteria were positively associated with metformin use," said study researcher Juan S. Escobar, Ph D, of the Vidarium Research Center in Medellin, Colombia. "Although we are not the first to demonstrate alterations in the gut microbial community associated with intake of this medication, our study is unique in matching cases and control on sex, age and body mass index, which makes our findings robust," Dr. Even so, he cannot claim a causal relationship yet, as the study was based on observational data. However, the findings may have some clinical relevance, he said, both for preventing disease and helping clinicians tailor treatments not only for those with type 2 diabetes but for other diseases associated with dysfunction in the gut microbiota. "Alterations in the microbiome have been shown to be central in many chronic diseases," he said, ''including obesity, cardiovascular disease, and diabetes, among others. In the case of type 2 diabetes (T2D), it was demonstrated a few years ago that patients had an altered gut microbiome relative to non-diabetic people. What is new with our study is that yes, patients with T2D have an altered microbiota, but most alterations are due to metformin treatment rather than the disease itself." In a community-based, observational study, 28 men and women with type 2 diabetes, were evaluated; half of the participants were taking metformin and half were not. If you have Polycystic Ovary Syndrome (PCOS) and have been prescribed metformin, chances are you have a lot of questions and concerns about taking this medication. The majority of women with PCOS have high insulin levels which cause weight gain, cravings, and even dark patches on your skin. Over time, exposure to high insulin levels can make you insulin resistant or turn into type 2 diabetes. Metformin works to lower your insulin and reduce your risk for diabetes. Metformin is one of the oldest and most studied drugs available in the United States. Other names for metformin include Glucophage, Glucophage XR, glumetza, and fortamet. Although it’s not labeled for use in women with PCOS, metformin is one of the most common medications used to manage the condition.
