Semaglutide

Summary

  • Semaglutide is used to treat type 2 diabetes and manage obesity. It helps control blood sugar levels in diabetes patients, aids in weight loss, and reduces cardiovascular risks such as heart attack or stroke in people with type 2 diabetes and heart disease.

  • Semaglutide mimics a hormone called GLP-1 which increases insulin release and slows digestion when blood sugar is high. This helps regulate blood sugar, control appetite and promote weight loss.

  • Semaglutide is usually taken as a once-weekly injection under the skin or as a daily oral tablet. The starting dose is typically 0.5 mg once a day for 4 weeks, which can be increased to 1 mg once a day. The highest dose is 2 mg once a day.

  • Common side effects of Semaglutide include nausea, vomiting, diarrhea, constipation, and abdominal pain. More serious adverse effects can include pancreatitis, gallbladder issues, low blood sugar, thyroid tumors, and rarely, kidney problems or allergic reactions.

  • Semaglutide should not be used by individuals with a personal or family history of thyroid cancer or Multiple Endocrine Neoplasia type 2. It's not recommended for pregnant or breastfeeding women. It can affect the absorption of certain vitamins and oral contraceptives. Always consult your doctor before stopping Semaglutide.

Indications and Purpose

How does Semaglutide work?

Semaglutide mimics a natural hormone called GLP-1 (glucagon-like peptide-1). It stimulates insulin release when blood sugar is high, lowers the release of glucagon (a hormone that raises blood sugar), and slows stomach emptying. These actions help regulate blood sugar, control appetite, and promote weight loss, making it effective for diabetes management and obesity treatment.

Is Semaglutide effective?

Clinical trials have shown that Semaglutide significantly lowers blood sugar levels and promotes weight loss. In studies, patients with type 2 diabetes achieved better glycemic control compared to other treatments. For obesity, participants lost an average of 10-15% of their body weight. Additionally, Semaglutide reduced cardiovascular risks in diabetic patients with heart disease, demonstrating its overall effectiveness.
