When a new peptide is approved by the FDA, it rarely generates as much media and social attention as Semaglutide. Most people recognize it by the brands Ozempic and Wegovy. Ozempic was originally approved for use in the treatment of Type 2 Diabetes, but the peptide soon attracted significant attention for its ability to support weight loss, as confirmed by numerous online transformations.
In addition to its primary uses, Semaglutide also offers several unexpected health benefits that may be significant to the patient’s overall health.
What is Semaglutide and How Does it Work?
Semaglutide is a synthetic peptide from the group of GLP-1 receptor agonists, whose action is based on the imitation of a natural mammalian hormone that participates in the regulation of glucose metabolism. Its effects include stimulating insulin secretion (a pancreatic hormone) in response to blood sugar levels, reducing appetite, and prolonging the feeling of satiety. In addition, Semaglutide can slow the passage of food through the digestive tract (primarily the stomach), contributing to lower calorie intake. Thanks to these mechanisms of action, this peptide helps control glycemia and supports weight loss. The drug is commonly administered by subcutaneous injections, once weekly.
What are the Benefits of Semaglutide Beyond Weight Loss?
Although today Semaglutide is commonly associated with weight loss, its role in medicine is much broader and dates back to the early days of Type 2 Diabetes therapy. Weight loss is only one indication, while the metabolic and protective benefits were primarily the reasons for its introduction into clinical practice and consideration for human application.
Diabetes
Semaglutide was introduced as a therapeutic option for Type 2 Diabetes in 2017, after scientific studies and clinical trials in humans confirmed its strong impact on glycemic control. Research has shown that regular use of this peptide can significantly reduce HbA1c levels, often by up to 2 percentage points, representing a clinically relevant improvement. Compared to other therapies, a greater proportion of patients who used Semaglutide achieved the recommended glycemic targets and improved the condition of their primary disease.
In addition to regulating blood sugar levels, several other benefits have been observed. Among them are weight loss, beneficial effects on cardiovascular health, and potential protection of kidney function. By reducing the harmful consequences of chronic hyperglycemia, Semaglutide can contribute to preserving the development of chronic kidney disease, as well as preventing the progression of kidney failure. Due to the promising results, a large clinical trial evaluating the effect of Semaglutide on the progression of chronic kidney disease in patients with Type 2 Diabetes was completed much earlier than planned, as the interim findings supported the assumptions about the therapy’s success.
Cardiovascular Disease
Current scientific research shows that Semaglutide has a pronounced protective effect on the cardiovascular system. In patients with obesity or increased body weight who already have cardiovascular disease, the administration of this peptide can be associated with a lower frequency of severe cardiac and cerebrovascular incidents. This benefit was observed regardless of the presence of Type 2 Diabetes. Within the framework of extensive clinical research that included patients with this metabolic disease, it was shown that the Semaglutide therapy protocol can significantly reduce the risk of severe complications, as well as death, with a total relative risk reduction of about one-quarter compared to the placebo group of subjects. In addition, research conducted in patients without Type 2 Diabetes confirmed similar findings, with approximately a fifth lower risk of these adverse events.
Heart Failure
Clinical trials in humans also dealt with the use of Semaglutide in patients with heart failure associated with obesity, regardless of whether they had Type 2 Diabetes or not. The results showed that therapy with this synthetic peptide can improve the clinical picture of heart failure, reducing symptoms such as fatigue, shortness of breath, and peripheral edema. In addition to the patient’s improved condition, functional benefits were observed, including greater mobility, fewer limitations in daily activities, and increased endurance during physical exertion. These improvements were commonly associated with weight reduction, further indicating the potential benefit of Semaglutide in this patient population.
Potential Future Uses
There are numerous studies currently underway or planned in the future that aim to test whether Semaglutide can be used in other medical conditions. Among them are polycystic ovary syndrome (PCOS), various types of addiction, as well as neurological disorders such as Alzheimer’s and Parkinson’s disease.
This GLP-1 agonist is also being investigated for sleep disorders, including sleep apnea, as well as for liver disease associated with metabolic problems. Specific attention is paid to the disease that was previously known as non-alcoholic fatty liver disease (NAFLD), and today is called metabolically dysfunctional steatosis liver disease (MASLD).
What Side Effects and Risks are Associated with Semaglutide?
The use of Semaglutide in patients can cause specific side effects, which are generally mild to moderate and often resolve as the body gradually adapts to the compound. Through scientific studies, the most frequently observed side effects include nausea, vomiting, diarrhea, constipation, and abdominal pain. When this peptide is used together with specific antidiabetic drugs, there is a risk of lowering blood sugar levels (hypoglycemia), which can be fatal. In clinical trials in humans, about a fifth of patients discontinued the therapy protocol due to side effects. To reduce discomfort during use, the peptide dose can be gradually increased over several weeks.
There are specific limitations during the therapeutic protocols: Semaglutide is not recommended for patients diagnosed with Type 1 Diabetes, diabetic ketoacidosis, or a history of pancreatic or specific forms of thyroid cancer. Also, the peptide is not intended for pregnant women, nursing mothers, or children under eighteen years of age. Since one of the primary effects of Semaglutide is delayed gastric emptying, its absorption may be affected, so it is crucial to monitor the effectiveness and side effects of these medications during therapy.
How Do I Know if Semaglutide is Right for me?
Before you decide to try Semaglutide, be sure to check with your doctor or healthcare team to determine whether this medication is right for you and whether it is indicated for your condition. It is crucial that you understand both the potential benefits and possible risks of the therapy. The two biggest challenges in starting or continuing this GLP-1 agonist are currently its cost and availability. Over 28 days of use, the average cost of the peptide is approximately $1,000, but the actual cost may vary depending on insurance, prescribed dosage, and peptide brand. There are options for discounts, coupons, and assistance programs, but due to high demand, pharmacists sometimes struggle to maintain sufficient inventory.
If you and your doctor decide that Semaglutide is an appropriate treatment protocol, you will receive a prescription for the optimal dose. Your health care team will also show you how to properly administer the injection and monitor possible side effects and the medication’s effectiveness. Although Semaglutide can provide significant health benefits, it is not a one-size-fits-all solution. Maintaining a healthy diet and regular exercise remains crucial to achieving long-term health.
