Semaglutide is a drug primarily prescribed by healthcare providers to treat type 2 diabetes. It is also remarkably effective in helping patients lose weight when used with a healthy diet and exercise. Semaglutide is on everybody’s lips these days, as it is the active ingredient in popular brand-name drugs like Ozempic, Wegovy, and Rybelsus.
What is semaglutide?
Semaglutide is the active ingredient in several diabetes and weight loss drugs like Ozempic, Wegovy, and Rybelsus. This compound is a synthetic form of the naturally occurring hormone called glucagon-like peptide-1 (GLP-1).
Semaglutide’s multiple benefits include: helping to lower blood sugar, reduce body weight, and lower the risk of cardiovascular events—like heart attack, stroke, or heart disease.
How does semaglutide work?
Semaglutide is a synthetic compound that imitates the effect of the natural hormone GLP-1 in the body. Semaglutide is officially classified as a glucagon-like peptide-1 receptor agonist, and it impacts blood sugar metabolism and calorie intake.
After eating a meal, your intestines release a hormone called GLP-1, which signals your pancreas to release more insulin. Insulin is a hormone that plays a crucial role in reducing blood sugar levels by facilitating the entry of glucose (sugar) into cells, where it can be used for energy or stored for later use. GLP-1 is especially important in ensuring that insulin is released at the right times, particularly after meals when blood sugar levels typically rise.
GLP-1 also has an impact on the rate at which your stomach empties. When the pancreas releases GLP-1, it helps control the pace at which food moves from the stomach to the small intestine. This action can slow down the absorption of nutrients, including glucose (sugar), from the digestive tract into the bloodstream. Consequently, this prevents rapid spikes in blood sugar levels after meals. Additionally, slower stomach emptying can create a feeling of fullness, reducing overall food intake and contributing to weight management.
How does semaglutide cause weight loss?
Semaglutide is most effective as a chronic weight management aid when combined with lifestyle changes like a reduced-calorie diet and regular exercise.
When taken correctly, semaglutide can affect weight loss through two primary actions: blood sugar management and appetite regulation.
Blood Sugar Management
Semaglutide stimulates the pancreas to release insulin. This hormone is crucial in transporting glucose (sugar) from the bloodstream into cells, where it can be utilized for energy. By facilitating this process, semaglutide helps maintain stable blood sugar levels, reducing the likelihood of sudden energy fluctuations that can trigger cravings for high-calorie foods.
Furthermore, semaglutide effectively inhibits the production of glucagon, another hormone responsible for elevating blood sugar levels. Glucagon prompts the liver to release stored glucose into the bloodstream, but semaglutide intervenes in this process. By controlling glucagon, semaglutide helps keep blood sugar levels steady, mitigating the hunger pangs often caused by low blood sugar.
Appetite Regulation
Semaglutide also influences appetite by interacting with GLP-1 receptors in the brain, particularly in the hypothalamus. When semaglutide binds to these receptors, it signals the brain to reduce appetite and curb cravings. This means that individuals taking semaglutide tend to experience reduced hunger and greater satisfaction from smaller meals.
Additionally, semaglutide slows down the rate at which the stomach empties its contents into the small intestine. This delay in stomach emptying leads to prolonged feelings of fullness after eating, ultimately reducing the inclination to consume more food.
It's important to note that semaglutide is typically prescribed with lifestyle modifications such as calorie reduction and increased physical activity. It is not intended to be the sole treatment for obesity but rather a supportive component of a comprehensive approach to weight management.
