Many people are constantly searching for a great weight loss option that can help them lose weight safely and quickly. While diets and other mechanisms have worked fairly well, a new method is making rounds in the market. What is it?
Well, the semaglutide injections, of course. The U.S. Food and Drug Administration has approved these anti-obesity or weight loss medications, which have been on the market since 2021.
This injectable drug has been used in chronic weight management for around 70% of American adults who are overweight and obese. While it did show effective results, research continues to look into more of its benefits. If you are someone who has heard about Semaglutide injection and wants to know more about what it is and how it works, then you have landed on the right page. Hop on below to read a detailed guide on it below:
What is a Semaglutide?
The Semaglutide injection is from a class of medication called glucagon-like peptide-1 receptor agonists (GLP-1 RAs). This particular class of drug acts like the GLP-1 hormone, which is released from the gut in response to eating.
The GLP-1 hormone enables the body to produce more insulin, which helps reduce glucose—blood sugar levels—in the body. Hence, it is one major reason why healthcare professionals have used the semaglutide injection to treat those with Type 2 diabetes for over 15 years.

How Does Semaglutide Work for Weight Loss?

Now that you have a basic understanding of what semaglutide injection is, we are sure you might want to learn how this weight loss medication works. Remember how we told you how semaglutide injection mimics the GLP-1 hormone in the brain?
Well, this weight loss medication is a GLP-1 receptor agonist. It takes over the GLP-1 receptors’ place in the brain, hindering appetite. The GLP-1 agonist targets the brain centers that regulate appetite and enable an individual to eat less. The medication works by slowing down your general metabolism, and hence, your stomach empties slower, making you feel full for a longer time.
The medication is recommended for long-term use if healthcare professionals believe that it might be effective for you. This is because, with long-term use, these weight loss medications have proven to help people lose weight and keep it at a maintained level. However, what should be ensured is that the semaglutide medications should not be consumed alongside semaglutide-containing products like Ozempic, Rybelsus, or some other GLP-1 receptor agonist medicines.
Who Can and Cannot Use Semaglutide for Weight Loss?
The semaglutide injection can be used by adults and children over twelve based on their overall BMI – body mass index – and in the presence of certain health conditions. The weight loss medication is generally used by people who meet one of the following criteria:
- Those who are overweight and have a body mass index (BMI) of 27 kg/m2 or over, along with those obese with BMI > 30 kg/m2, with at least one weight-related condition, such as Type 2 diabetes, high blood pressure, or increased levels of cholesterol.
- Adolescents 12 years of age and older whose initial BMI is at or above the 95th percentile for age and sex, based on the growth charts.
- The medication is also prescribed to many adults to reduce the risk of heart attack, stroke, or other heart conditions in people who are obese or overweight.
However, while the semaglutide injection can be prescribed to several adults and children, there is a percentage of people who should avoid these weight loss medications at all costs. Who are they? Well, it is recommended to prevent semaglutide injections if you have:
- History of medullary thyroid cancer.
- History of any gallbladder disease or pancreatitis.
- Multiple endocrine neoplasia syndrome type 2 (MEN2)
How Long Does it Take for Semaglutide to Work?
There is no exact timeline for how the semaglutide injections work and many people may start observing the results and impacts in four weeks. However, it may take a few months for a full visible effect to come through.
One study showed that after 68 weeks of proper use, many adults lost an average of 15.9 kg of weight with these weight loss medications, which is about 15% of their body weight.
So, the positive impacts or overall results might depend on the dose you are taking. Your doctor will start with an initial low dose and may increase it up as per your requirements and needs. This directly signifies the weight loss result you foresee.
Are There Any Side Effects of Semaglutide Injections?

While fairly uncommon, there can be times when individuals who take semaglutide injections might face any side effects. However, the side effects of these weight loss medications are typically mild. Here are some side effects that people may encounter:
- Dizziness
- Fatigue
- Gastrointestinal issues – diarrhea, gassiness and constipation.
- Stomach issues – nausea, distention or pain, vomiting.
- Headache
Among all these side effects, gastrointestinal issues are the most common, but the impacts of these side effects can be tamed by starting the medication at a lower dose and then notching it up based on your needs and requirements. However, make sure that you do this under a healthcare professional’s supervision and recommendation.
