Is There a Once a Week Injection that Controls My Diabetes and Helps with Weight Loss?
According to a 2017 report from the CDC, more than 100 million Americans live with diabetes or prediabetes. As we shared on the blog several months ago, nearly 15% of the adult population in Tennessee has diabetes, while 35.8% has prediabetes.
As diabetes becomes a growing concern, many patients are asking their doctor about new and alternative solutions, such as the once-a-week diabetes injection. In addition to helping control diabetes, these injections can also contribute to weight loss, making them a win-win for many patients.
Ozempic, Trulicity & More: GLP-1 Receptor Agonist Medications
Adults with diabetes may have new management options thanks to a class of medications known as GLP-1 receptor agonists. These drugs aid the body in releasing insulin as a response to elevated blood sugar. These drugs are not insulin medications. Rather, they limit the amount of sugar that can enter the bloodstream from the liver. GLP-1 receptor agonists also control the rate at which food leaves the stomach. GLP-1 receptor agonists may be used alone or may be prescribed in addition to insulin.
