Saxenda for Weight Loss

Saxenda or liraglutide (generic name) is a daily injection for weight loss/weight management or treatment of type 2 diabetes. It is used along with diet, exercise and other medications to control blood sugar levels in patients with type 2 diabetes.

How does Saxenda work for weight loss and blood sugar control

Your body naturally produces an appetite hormone known as glucagon-like peptide-1 (GLP-1) that helps to regulate your hunger. Saxenda belongs to a class of medications called glucagon-like peptide-1 (GLP-1) agonists. Saxenda works like GLP-1 by regulating your appetite and slowing down the emptying of the stomach, thus making you feel full quicker which can lead to eating fewer calories and losing weight. Furthermore, it signals your body to produce more insulin when blood sugar level is high, thus helping with blood sugar control if you have diabetes. Saxenda has been shown to decrease A1C by 1%.

Other medication in same class of drugs and works similarly is Ozempic, a once a week injection for weight loss and diabetes management.
