Potential of GLP-1 Medications: What Are The Benefits And Risks?

GLP-1 (Glucagon-Like Peptide-1) medications are a revolutionary class of drugs transforming the landscape of diabetes management and weight loss strategies. These medications, which mimic the natural hormone GLP-1 in our bodies, have shown remarkable effectiveness in controlling blood sugar levels and offering additional cardiovascular benefits. In this guide, we will discuss GLP-1 medications, their benefits, potential side effects, and the emerging role they play in modern healthcare.

When GLP-1 Medications Are Considered?

When GLP-1 Medications Are Considered?GLP-1 (Glucagon-Like Peptide-1) medications are considered for several reasons, primarily in the context of managing type 2 diabetes and, increasingly, for weight management. Here are the key scenarios when GLP-1 medications are typically considered:

  • Type 2 Diabetes Management

GLP-1 medications are often prescribed for individuals with type 2 diabetes. They work by enhancing insulin secretion, suppressing glucagon (which raises blood sugar), and slowing gastric emptying. This helps in better control of blood glucose levels.

  • Inadequate Glycemic Control with Other Medications

If a patient’s blood sugar levels are not adequately controlled with other diabetes medications like metformin, doctors may consider adding a GLP-1 medication to the treatment regimen.

  • Weight Management in Type 2 Diabetes

Given their effect on appetite suppression and potential for weight loss, GLP-1 medications are often considered for individuals with type 2 diabetes who are also overweight or obese. This dual benefit can lead to improved overall metabolic health.

  • Non-Diabetic Weight Loss

Some GLP-1 medications have been approved for weight management in non-diabetic individuals who are overweight or obese. Particularly when there are additional weight-related health issues such as hypertension, dyslipidemia, or obstructive sleep apnea.

  • Cardiovascular Health

Certain GLP-1 medications have shown benefits in reducing the risk of major cardiovascular events in patients with type 2 diabetes and established cardiovascular disease. They may be considered for patients who have both conditions.

  • Preservation of Beta-Cell Function

There is evidence suggesting that GLP-1 medications may help in preserving the function of beta cells in the pancreas. These are responsible for insulin production.

It’s important to note that the decision to use GLP-1 medications is individualized. This is based on the patient’s overall medical condition, preferences, and the presence of other health issues.

What Are Some Examples Of GLP-1 Medications?

What Are Some Examples Of GLP-1 Medications?GLP-1 medications have become a significant part of diabetes management and weight loss therapy. Some of the well-known examples of GLP-1 medications include:

Exenatide (Byetta, Bydureon)

Exenatide, marketed as Byetta for twice-daily injections and Bydureon for once-weekly injections, is one of the pioneering GLP-1 receptor agonists used in the treatment of type 2 diabetes. Byetta is particularly useful for patients who require more flexible dosing or are initiating GLP-1 therapy. While Bydureon’s extended-release formulation offers the convenience of less frequent dosing. Exenatide works by enhancing glucose-dependent insulin secretion, suppressing inappropriately elevated glucagon secretion, and slowing gastric emptying.

Liraglutide (Victoza, Saxenda)

Liraglutide is a versatile medication available in two different brands: Victoza for type 2 diabetes management and Saxenda for weight loss. Victoza improves blood sugar control by enhancing insulin secretion in response to high blood sugar levels and suppressing appetite. This can lead to weight loss. Saxenda contains a higher dose of liraglutide specifically targeted for weight management in obese or overweight individuals, including those with weight-related conditions like hypertension.

Dulaglutide (Trulicity)

Dulaglutide, known as Trulicity, is a once-weekly injectable GLP-1 medication designed for the treatment of type 2 diabetes. It helps to control blood sugar levels by increasing insulin secretion in response to meals and lowering the amount of sugar your liver produces. Its longer duration of action and weekly dosing schedule make it a convenient option for patients looking for a less frequent dosing regimen.

Semaglutide (Ozempic, Rybelsus, Wegovy)

Semaglutide is a newer GLP-1 receptor agonist with multiple formulations. Ozempic is a once-weekly injection for diabetes management, offering effective blood sugar control and significant benefits in terms of weight loss and cardiovascular risk reduction. Rybelsus is the first oral form of a GLP-1 medication, providing an alternative for those who prefer a pill to injections. Wegovy, another semaglutide brand, is approved for chronic weight management in adults with obesity or overweight with at least one weight-related condition like hypertension or type 2 diabetes.

Lixisenatide (Adlyxin)

Lixisenatide, sold as Adlyxin, is a once-daily injectable medication used for the treatment of type 2 diabetes. It functions similarly to other GLP-1 receptor agonists by enhancing glucose-dependent insulin secretion and decreasing glucagon secretion, thereby improving glycemic control. It is particularly effective at reducing postprandial blood glucose levels.

Albiglutide (Tanzeum)

Albiglutide, previously marketed as Tanzeum, was used in the treatment of type 2 diabetes. This medication, administered as a once-weekly injection, worked by increasing insulin production in response to high blood glucose levels and reducing the amount of glucose produced by the liver. However, due to commercial reasons, it has been discontinued in many markets and is no longer widely available.


Efpeglenatide is among the newer additions to the GLP-1 medication class. It is designed for the treatment of type 2 diabetes and, like other GLP-1 agonists, helps to regulate blood sugar levels by enhancing insulin secretion and suppressing glucagon release. Efpeglenatide is still gaining ground in terms of its usage and availability. Ongoing research is expected to further define its role in diabetes management.

Each of these medications, while having a common mechanism of action, offers unique benefits and considerations. Patients and healthcare providers must discuss the most appropriate medication. This should be based on individual health needs, lifestyle preferences, and treatment goals.

Which GLP-1 Is Taken Daily?

The GLP-1 (Glucagon-Like Peptide-1) medications that are taken daily are:

  • Liraglutide (Victoza): Liraglutide, sold under the brand name Victoza, is a daily injectable GLP-1 receptor agonist used for the treatment of type 2 diabetes. It is administered once a day.
  • Lixisenatide (Adlyxin): Lixisenatide, marketed as Adlyxin, is another GLP-1 receptor agonist that is administered as a once-daily injection. It is used specifically for the treatment of type 2 diabetes.

These daily GLP-1 medications are useful for patients who may prefer or benefit from a more frequent dosing schedule. Such as those who need more immediate adjustments in blood sugar control or those who find it easier to incorporate medication into a daily routine.

What Are The Risks Of GLP-1 Medications?

What Are The Risks Of GLP-1 Medications?GLP-1 (Glucagon-Like Peptide-1) medications, while highly effective in managing type 2 diabetes and aiding in weight loss, do come with potential risks and side effects. It’s important to understand these risks to make informed treatment decisions. The main risks associated with GLP-1 medications include:

Gastrointestinal Side Effects

Common side effects of GLP-1 medications include nausea, vomiting, diarrhea, and constipation. These symptoms are often mild and tend to improve over time as the body adjusts to the medication.


Although less common with GLP-1 medications alone, the risk of low blood sugar (hypoglycemia) increases when they are combined with other diabetes medications, especially sulfonylureas or insulin.


There is a potential risk of pancreatitis (inflammation of the pancreas) associated with GLP-1 medications. Patients are advised to be aware of symptoms like severe abdominal pain, which may indicate pancreatitis.

Allergic Reactions

Some individuals may experience allergic reactions to GLP-1 medications, presenting as rash, itching, or even more severe reactions like anaphylaxis in rare cases.

Gallbladder Issues

There have been reports of gallbladder problems, including gallstones, in patients taking GLP-1 medications, possibly related to rapid weight loss.

Kidney Problems

GLP-1 medications can affect kidney function, particularly in patients with pre-existing kidney conditions. This is often due to dehydration resulting from nausea or vomiting.

Thyroid Tumors

In animal studies, some GLP-1 medications have been linked to a type of thyroid tumor called C-cell tumors, including medullary thyroid carcinoma. It’s unclear if this risk applies to humans. However, these medications often carry a warning about this potential risk.

Injection Site Reactions

As with any injectable medication, GLP-1 medications can cause reactions at the injection site, such as redness, swelling, or pain.

Risk in Specific Populations

GLP-1 medications are generally not recommended for pregnant or breastfeeding women and may have specific risks for other groups. Such as those with a history of pancreatitis or gastrointestinal diseases.

Patients must discuss the potential risks and benefits of GLP-1 medications with their healthcare provider. Also, consider their individual health status and medical history. Monitoring and regular follow-ups are important to ensure the safe and effective use of these medications.


In conclusion, GLP-1 medications have emerged as a significant advancement in treating type 2 diabetes and aiding in weight loss, offering a range of benefits from improving blood sugar control to promoting heart health. However, like all medications, they come with potential side effects, including gastrointestinal discomfort, risk of low blood sugar, and possible concerns regarding pancreatitis and thyroid health.
