What are Semaglutides?

Semaglutides – an innovative class of medications, known as GLP-1 receptor agonists – are changing the therapeutic landscape for individuals battling obesity and type 2 diabetes.

Semaglutides imitate the GLP-1 hormone (short for Glucagon-like Peptide-1) that our bodies naturally produce, integral to regulating appetite, influencing how our stomachs process food, and managing the balance of insulin and glucagon for optimal metabolic function.

Drugs like Ozempic, Wegovy and Mounjaro are at the forefront of the Semaglutide class of drugs, signifying a transformative step in chronic disease management. They are part of an evolving story that began with the first-generation GLP-1 receptor agonist, Exenatide. But the newcomers such as Ozempic have since ascended to prominence by offering patients a more manageable and less frequent dosing schedule. This attribute of Semaglutides has been a game-changer, enhancing patient adherence and fitting more seamlessly into daily life (1).

The essence of Semaglutides lies in their dual-action approach: not only do they help stabilize blood sugar levels post-meal, but they also contribute to a feeling of fullness, which is a vital factor in weight management (2). This multifunctional capacity positions Semaglutides as a key player in the management of type 2 diabetes and as a significant ally in the quest for sustainable weight control.

As we progress through this article, we will explore the nuances of how Semaglutides operate, the clinical evidence supporting their use, and the practical considerations for those incorporating these medications into their healthcare regimen. Next, let’s consider how exactly Semaglutides function.

How do Semaglutides function?

Semaglutides’ effectiveness comes from their ability to imitate the human glucagon-like peptide-1 (GLP-1) hormone, which is naturally produced in the gut following meals. GLP-1 is essential in controlling appetite and food intake.

By mirroring the actions of GLP-1, Semaglutides essentially take over the body’s system for regulating hunger, leading to a decrease in appetite and a reduction in calorie consumption.

But how exactly do Semaglutides manage to regulate weight and blood sugar level efficiently?

According to the latest scientific research, the following changes happen in your body after you take Semaglutides:

Improved insulin secretion: Semaglutides boost insulin release when blood sugar levels go up. This is very important for people with type 2 diabetes, who usually have problems making enough insulin or whose bodies don’t respond well to insulin (3).
Lower glucagon release: Besides increasing insulin production, Semaglutides also reduce the release of glucagon, which is a hormone that usually increases blood sugar levels. And by lowering glucagon, Semaglutides aid in keeping blood sugar levels more stable (4).
Slower gastric emptying:Another key effect of Semaglutide is to slows down how quickly the stomach empties food into the intestine. This slower process helps control the sudden rise in blood sugar that often happens after meals, which is a frequent issue for people with diabetes (5).
Reduce food intake:Additionally, Semaglutides help with weight loss by reducing the number of calories you eat. They do this by making you feel full and decreasing your appetite, which helps you eat less and manage your weight more effectively. This way of working has been especially helpful for people with obesity, as shown in detailed clinical trials where participants lost a lot of weight and saw improvements in different health measures (6).

What are medical benefits of Semaglutides?

As you can imagine, the ability of Semaglutides to control appetite, stomach emptying, and critical hormones such as insulin has far reaching health consequence. Several published clinical trials showed evidence for the benefit of Semaglutides for Type 2 Diabetes, obesity, and cardiovascular diseases that we highlight below.

Type 2 diabetes:

Semaglutides have been primarily used for treating type 2 diabetes, and their role in this area is well-recognized. They are effective in controlling blood sugar levels and significantly reduce the risk of diabetes-related complications. The FDA has approved Semaglutides like Ozempic and Rybelsus for lowering blood sugar in adults with type 2 diabetes. To be most effective, they are to be used alongside diet and exercise (7).

Weight loss:

Besides diabetes management, a recent large clinical trial (STEP trial) highlighted Semaglutides’ efficacy in supporting weight loss, particularly for individuals with obesity. Results of this trial, published in the New England Journal of Medicine, were significant, showing an average weight loss of around 15.3 kg in participants. Additionally, these results were paired with improvements in various health markers, including reductions in waist size, blood fat levels, blood sugar, and blood pressure, all of which are risk factors for heart disease and diabetes (1).

Cardiovascular health:

Although no clinical trial clearly showed the direct impact of Semaglutides in cardiovascular diseases, studies including a report in the New England Journal of Medicine have shown promising results (8). Semaglutides have been shown to reduce the likelihood of major adverse cardiovascular events in type 2 diabetes patients, for example non-fatal types of stroke and myocardial infarction. These outcomes are crucial for long-term cardiovascular health management.

By targeting both blood glucose levels and body weight, Semaglutides effectively address two major contributors to cardiovascular risk.

What side effects do Semaglutides have?

Semaglutides, like all medications, can have side effects. Commonly reported ones include gastrointestinal symptoms such as nausea, diarrhea, and constipation. These side effects published in a study in the Journal of American Medical Association are generally mild to moderate and tend to decrease over time as the body adjusts to the medication (9).

It’s critical for patients to discuss these potential side effects with their healthcare provider and to understand that these reactions are often manageable and temporary.

Another aspect of Semaglutide treatment to consider is the risk of hypoglycemia, especially when used in combination with other diabetes medications that can lower blood sugar levels. Patients need to be aware of the symptoms of low blood sugar and how to manage them.

Despite these side effects, comprehensive analysis of multiple clinical trials involving over 2000 patients and published in the Annals of Medicine demonstrated that Semaglutides have a strong safety profile (10). These clinical trials and studies not only demonstrated Semaglutides’ effectiveness in managing type 2 diabetes and aiding in weight loss but also their overall tolerability in diverse patient populations.

What are differences between different types of Semaglutides?

Similarities:

All Semaglutides work by increasing insulin secretion when blood sugar is high and decreasing glucagon release, which usually raises blood sugar. This helps manage blood sugar levels in type 2 diabetes. Additionally, they aid in weight control by reducing hunger and calorie intake, contributing to overall diabetes management and health improvement.

Differences:

Differences between Semaglutides and earlier versions of GLP-1 drugs:

Semaglutides represent a significant advancement compared to earlier versions of GLP-1 drugs, primarily in their administration and duration. Earlier versions of GLP-1 drugs such as Exenatide and Lixisenatide required frequent injections due to their short half-life (i.e., they could not stay in the body for a long period).

On the contrary, Semaglutides have longer half-life and offer greater convenience with just once-weekly dosing. This development in dosing frequency has greatly enhanced patient convenience, making it easier for individuals to adhere to their treatment regimen. This shift to less frequent dosing while maintaining effectiveness represents a notable evolution in diabetes medication, balancing efficacy with patient lifestyle and treatment adherence.

Differences among Semaglutides:

Although different Semaglutides such as Ozempic and Wegovy largely operate in the same manner, they have slight differences in terms of:

Dosage Forms: Some Semaglutides are available as injectables, while others may come in tablet form.
Dosing Frequency: Differences in how often each Semaglutide needs to be taken, ranging from daily to weekly.
Side Effect Profiles: Variations in the type and frequency of side effects experienced by users.
Efficacy Levels: The degree to which each Semaglutide type effectively manages blood sugar and weight loss.
Approval for Use: Differences in the medical conditions each Semaglutide type is approved to treat.

The table below summarizes key distinguishing features of different Semaglutide drugs.

Semaglutide Type	Dosage Forms	Dosage Frequency	Side Effects	Efficacy Level	Approval for Use
Ozempic (11)	Injection (0.25 mg, 0.5 mg, 1 mg, 2 mg per injection)	Once weekly	Nausea, vomiting, diarrhea, abdominal pain, constipation	Improves glycemic control, reduces risk of major adverse cardiovascular events	Type 2 diabetes, established cardiovascular disease
Wegovy (12)	Injection (0.25 mg, 0.5 mg, 1 mg, 1.7 mg, 2.4 mg)	Once weekly	Nausea, diarrhea, vomiting, constipation, abdominal pain, headache, fatigue, dyspepsia, dizziness, abdominal distension, eructation, hypoglycemia in patients with type 2 diabetes, flatulence, gastroenteritis, gastroesophageal reflux disease	Chronic weight management in adults with obesity	Obesity, overweight with weight-related comorbid conditions such as hypertension, type 2 diabetes, or dyslipidemia
Rybelsus (13)	Oral tablet (3 mg, 7 mg, 14 mg)	Once daily	Nausea, abdominal pain, diarrhea, decreased appetite, vomiting, constipation	Improves glycemic control in adults with type 2 diabetes	Type 2 diabetes

Semaglutide medications are tailored to each individual patient’s needs. For personalized and safe use of Semaglutide, it’s crucial to consult a physician to establish the right medication, dosage, and usage frequency. Remember, Semaglutides are prescription medication and should only be taken when prescribed by a healthcare professional.
