Weight Loss

Semaglutide and Tirzepatide are weightloss injections that assist with lowering appetite and you will feel fuller when eating. They are a glucagon-like peptide-1 (GLP-1) receptor agonist and occupies the GLP-1 receptor in the brain that regulates appetite.



Semaglutide, a medication originally developed to treat type 2 diabetes, has also been found to be effective for weight loss in people with obesity. Here's how Semaglutide works for weight loss:


1. **Appetite suppression**: Semaglutide works by activating GLP-1 receptors in the brain, which helps to reduce appetite and food intake. This can lead to a decrease in calorie consumption and promote weight loss over time.


2. **Slows down gastric emptying**: Semaglutide also slows down the emptying of the stomach, which can contribute to feelings of fullness and satiety. This effect can help individuals eat less and feel satisfied with smaller portions of food.


3. **Calorie reduction**: By reducing appetite and promoting feelings of fullness, Semaglutide can help individuals consume fewer calories, which is essential for weight loss. When combined with a healthy diet and regular exercise, Semaglutide can enhance weight loss efforts.


4. **Metabolic effects**: Semaglutide may also have metabolic effects that contribute to weight loss, such as improving insulin sensitivity and reducing fat accumulation in the body.


5. **Clinical trials**: Clinical trials have demonstrated that Semaglutide, when used at higher doses specifically formulated for weight management, can lead to significant weight loss in individuals with obesity or overweight. Participants in these trials typically achieved greater weight loss compared to those receiving a placebo.


6. **Administration**: Semaglutide for weight management is administered as a subcutaneous injection once a week.


Tirzepatide is a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist that works by targeting multiple pathways to improve glycemic control and promote weight loss.


Here's how tirzepatide works for weight loss:


1. **GLP-1 receptor agonism**: Tirzepatide activates the GLP-1 receptor, which leads to increased insulin secretion in response to elevated blood glucose levels. This helps to lower blood sugar levels after meals and reduces the production of glucose by the liver. GLP-1 receptor activation also promotes satiety, which can lead to reduced food intake and subsequent weight loss.


2. **GIP receptor agonism**: In addition to GLP-1 receptor activation, tirzepatide also activates the GIP receptor. GIP is another hormone that plays a role in glucose and energy metabolism. By targeting the GIP receptor, tirzepatide can further enhance insulin secretion and inhibit glucagon release, both of which contribute to improved glycemic control and reduced food intake.


3. **Reduction of appetite and food intake**: 

Through its actions on the GLP-1 and GIP receptors, tirzepatide helps to regulate appetite and food intake. By promoting feelings of fullness and reducing hunger, tirzepatide can help individuals consume fewer calories, leading to weight loss over time.
