Modern medicine continues to enhance treatment options for chronic conditions like type 2 diabetes and obesity. One such advancement is the use of GLP-1 receptor agonists, a class of medications that may complement your current treatment plan.
GLP-1 is a natural hormone produced by your body that helps regulate blood sugar levels by managing glucose metabolism and insulin release (the hormone responsible for regulating glucose).
Pharmaceutical companies have created synthetic GLP-1 medications that mimic the actions of this hormone. These medications, commonly administered via injections, are referred to as GLP-1 receptor agonists. By imitating the effects of GLP-1, these synthetic versions perform similar functions, including:
- Helping to control appetite and blood sugar levels.
- Assisting the pancreas in releasing the appropriate amount of insulin.
- Slowing down the rate at which food exits the stomach, helping you feel fuller for a longer period.
All three of these effects can contribute to weight loss.
The GLP-1 hormone plays a role in appetite suppression, particularly in the hypothalamus region of the brain. It also slows the emptying of the stomach and influences the release of insulin and glucagon from the pancreas.
By taking a GLP-1 receptor agonist, you’re enhancing your body’s natural GLP-1 levels and boosting its beneficial effects.
Before considering the addition of a GLP-1 receptor agonist to your treatment for newly diagnosed type 2 diabetes, it’s important to consult a board-certified and licensed physician. Gaining a better understanding of this medication can help you determine whether it’s a suitable option for your needs.
GLP-1 receptor agonists are approved by the FDA for managing type 2 diabetes, as well as for obesity or overweight individuals with obesity-related conditions such as high cholesterol or nonalcoholic fatty liver disease. Overweight is defined as having a body mass index (BMI) between 25 and 30, while obesity is defined as a BMI of 30 or higher.
If you meet one or both of these criteria, GLP-1 therapy may be a suitable option for you.
Not everyone with type 2 diabetes or obesity requires GLP-1 receptor agonist therapy. Metformin, a commonly used medication in the biguanide class, is typically the first-line treatment for lowering blood sugar in type 2 diabetes.
If your diabetes is well-managed with traditional treatments, your doctor may not find a GLP-1 agonist necessary. However, if your blood sugar levels remain high, your doctor may recommend adding a GLP-1 receptor agonist alongside metformin.
According to clinical guidelines, GLP-1 receptor agonists are generally added to a type 2 diabetes treatment plan if you:
1. Cannot take metformin
2. Struggle to achieve target blood sugar levels over time
3. Experience complications such as:
- Heart failure
- Atherosclerosis
- Chronic kidney disease
In cases where type 2 diabetes is accompanied by other conditions (comorbidities), GLP-1 receptor agonists may be preferred due to their added cardiovascular, gastrointestinal, and weight-loss benefits, contributing to better overall health.
However, GLP-1 receptor agonists are not recommended if you:
- Are pregnant
- Are hypersensitive to GLP-1
- Have severe gastrointestinal conditions like inflammatory bowel disease (IBD)
- Are at a higher risk of certain thyroid cancers
If you have a history of pancreatitis, kidney failure, or gallbladder disease, GLP-1 receptor agonists may not be safe for you. Always consult your healthcare provider to determine the best treatment plan for your needs.
There are several types of GLP-1 receptor agonists available, all of which mimic the effects of the GLP-1 hormone but have different formulations, benefits, and potential risks. The best option for you will depend on which medication offers the greatest benefits with the least risk, based on your individual health needs.
FDA-approved GLP-1 receptor agonists include:
- Semaglutide (Rybelsus, Ozempic, Wegovy)
- Exenatide (Bydureon BCise, Byetta)
- Lixisenatide (Adlyxin)
- Lixisenatide/insulin glargine (Soliqua)
- Liraglutide (Saxenda, Victoza)
- Liraglutide/insulin degludec (Xultophy)
- Dulaglutide (Trulicity)
- Tirzepatide (Mounjaro)
For example, Ozempic (semaglutide) is approved for type 2 diabetes, while Wegovy (also semaglutide) is approved for obesity and overweight conditions with related health concerns.
The medication your doctor recommends will depend on its effectiveness, safety, and benefits for other health conditions. If weight loss is a key goal in your diabetes management, your doctor may choose a GLP-1 receptor agonist known for its strong weight-loss benefits.
All FDA-approved GLP-1 receptor agonists have been shown through clinical trials to effectively manage blood sugar levels in people newly diagnosed with type 2 diabetes. However, research is varied on which one is the "best." According to a 2024 systematic review and meta-analysis, the combination GIP/GLP-1 receptor agonist tirzepatide was found to be the most effective at controlling blood sugar.
For weight loss, data from a 2021 review supports semaglutide as the most effective option. However, the same 2024 meta-analysis cited earlier found that CagriSema, a combination of semaglutide and cagrilintide, was even more effective for weight loss. CagriSema is not yet FDA-approved in the United States.
The most common side effects of GLP-1 receptor agonists include nausea, vomiting, constipation, and diarrhea. Some people also experience headaches, increased infections, rapid heart rate, dizziness, and indigestion. According to the 2021 review, Exenatide XR had the lowest rate of gastrointestinal side effects, while semaglutide injections were associated with the highest rate of these side effects.
Most GLP-1 receptor agonists are administered by injection once or twice a week, with some exceptions. For example, Victoza is a daily injectable, and Rybelsus is the only FDA-approved GLP-1 receptor agonist available as an oral tablet, taken once daily.
If your doctor prescribes an injectable GLP-1 receptor agonist, it will likely come in a dosing pen—a handheld device with a fine needle that allows you to adjust your dose as directed by your doctor.
If you're uncomfortable giving yourself injections, you can have the injection administered at your doctor’s office, though there may be a charge for each visit. There are also resources available, such as instructional guides on the pharmaceutical company’s website, and your doctor can demonstrate how to give yourself the first dose.
The time it takes for a GLP-1 receptor agonist to start working varies by formulation. Some are fast-acting and used daily, while others are long-acting and may take weeks to reach therapeutic levels in the body.
If you stop taking a GLP-1 receptor agonist, you may experience rebound effects. As your body adjusts to the absence of the medication, symptoms like hunger, weight gain, and high blood sugar (hyperglycemia) may return. Because of this, diabetes and obesity treatments are often considered long-term.
In the STEP 1 clinical trial for semaglutide, participants regained up to two-thirds of the weight they had lost within a year of stopping the medication.
Currently, Wegovy and Zepbound are the only GLP-1 receptor agonists FDA-approved for treating obesity. FDA approval means they have passed the necessary efficacy and safety tests for public use.
However, other GLP-1 receptor agonists may still be safe for weight loss; they just haven’t undergone the specific trials required to be labeled for this purpose.
You don’t have to wait for your doctor to suggest a GLP-1 receptor agonist. If you think you might be a good candidate, be open and honest about why you want to consider adding it to your treatment plan.
By sharing your goals and any challenges you're facing, your doctor can guide you in making an informed decision about whether a GLP-1 receptor agonist is right for you.
Here are some questions that can help you get the most out of the conversation:
- Am I a good candidate for a GLP-1 receptor agonist? Why or why not?
- Would a GLP-1 medication enhance my current treatment plan?
- Which GLP-1 medication would be the best option for me?
- What benefits can I expect from taking a GLP-1 receptor agonist?
- What side effects should I be aware of?
- Are there any specific instructions or precautions I should follow?
- What kind of follow-up appointments or tests will be needed after starting a GLP-1?
It can also be helpful to learn about GLP-1 receptor agonists before your appointment. Familiarizing yourself with common terms and identifying specific medications you're interested in can make the discussion more productive.
Consistently using GLP-1 receptor agonists is key to getting the most out of your treatment. Here are some tips to help ensure you maximize the benefits:
- Follow your doctor’s dosing and administration instructions precisely.
- If using injections, have a healthcare professional show you the correct administration technique.
- Take your medication at the same time each day for consistency.
- Store your medication as directed, either in the refrigerator or at room temperature, based on the instructions.
- Support your treatment with healthy lifestyle habits, such as getting good sleep and staying hydrated.
- Stay in regular communication with your doctor and attend follow-up appointments.
- Keep a journal to track any side effects or reactions to the medication.
Remember, GLP-1 receptor agonists are usually part of a broader treatment plan, so combining them with a balanced diet and regular exercise is essential, whether you're managing type 2 diabetes, obesity, or both.
GLP-1 receptor agonists are medications used to treat type 2 diabetes and obesity, depending on the specific brand. They work by mimicking your body's natural GLP-1 hormone, which helps regulate blood sugar in various ways.
However, not everyone with type 2 diabetes or obesity requires or is eligible for GLP-1 receptor agonist therapy. Your doctor can explain the potential benefits, risks, and whether this treatment is a suitable option for you.
