What to Expect When Starting an Oral GLP-1 for Obesity

G lucagon-like peptide-1 receptor agonists, more commonly known as GLP-1s, have become popular treatments for obesity in recent years. These medications help people with obesity lose weight; improve blood pressure, blood sugar regulation, and lipid profiles; and reduce inflammation that can lead to chronic disease.

You may think of GLP-1s as injectable medications, but oral GLP-1s are also an option for people looking to better manage obesity through weight loss. If changes to your diet and exercise routine haven’t led to sufficient weight loss, your doctor may prescribe a GLP-1 to use alongside healthy lifestyle habits. They may suggest an oral GLP-1 in particular if it is a better fit for your routine and needs.

“The most common reason to prescribe an oral GLP-1 is the patient’s preference,” says Pruthvi Raj Velamala, MD, a board-certified obesity medicine physician at Beth Israel Lahey Health in Beverly, Massachusetts. Some people aren’t comfortable with injections and would prefer to take a daily pill versus weekly shots, he says. Plus, oral options can be less costly than injectable GLP-1s, and the pills don’t need to be stored in the refrigerator, so they may be more convenient for travel.

Here’s what to expect when starting an oral GLP-1 for obesity.

How to Prepare for Starting an Oral GLP-1 for Obesity

Treatment Instructions

The exact timing and steps of taking an oral GLP-1 will depend on which medication you’ve been prescribed. For example, if the medication contains salcaprozate sodium (SNAC) to enhance absorption in the stomach, as oral semaglutide does, you’ll need to follow a strict fasting routine. If you’ve been prescribed a small molecule drug, such as orforglipron, there are no fasting requirements. Be sure to read the instructions for your particular prescription.

    • Take the pill once a day, swallowing it whole. Depending on the medication, you may be instructed to take it in the morning or anytime that’s convenient for you. 
    • You may also need to take the medication with a specific amount of water on an empty stomach and wait 30 minutes before drinking anything else or eating. Again, this depends on the medication, so read the instructions provided with the prescription.

    What It’s Like to Take an Oral GLP-1 for Obesity

    When taking an oral GLP-1, you may experience:

    Reduced Food Noise

    People taking an oral GLP-1 may notice they think about food less often, which can begin within a few days or weeks of starting the medication, says Vinton.

    Decreased Appetite

    You may find that you feel full sooner when eating meals or don’t want to eat as often. Huang says it’s still important to nourish your body regularly with healthy, protein-rich foods to help maintain your metabolism and avoid losing too much muscle.

    Reduced Cravings

    “Many patients have reduced cravings and tolerability for higher-calorie foods, such as fried foods, ice cream, and candy,” says Vinton. Some people find themselves not wanting to drink alcohol or soda.

    Mindset Shifts

    Because GLP-1s can alter taste, you may find yourself avoiding social situations that revolve around food or alcohol. Emotional eating may also stop, in which case you’ll need to find other ways to cope with difficult emotions, such as journaling or therapy, says Dr. Velamala.

    Treatment Timeline

    Oral GLP-1 medications are designed to be started at a low dose to keep side effects to a minimum. The dose can often be increased every 30 days until you reach either your goals, the maximum you can tolerate without too many side effects, or the maximum dose available.

    Side Effects of Oral GLP-1 Drugs

    Common side effects of oral GLP-1s are similar to those of injectable GLP-1s, ranging from gastrointestinal discomfort to dizziness. Some can be mild and pass as your body gets used to the medication, while others can be overwhelming and are worth a chat with your doctor about how you can feel more comfortable.

    Rare but serious side effects include:

    • Gallbladder Inflammation Call your doctor if you experience any fever, severe stomach pain, or yellowing of the eyes or skin.
    • Serious Eye Complications Diabetic retinopathy, an eye disease related to blood sugar fluctuations, can cause vision loss. See your doctor regularly for checkups, and if you have diabetes, be sure to check and manage your blood sugar. Tell your doctor if you experience any changes in your vision.
    • Thyroid Cancer Avoid GLP-1s if you’re at risk for thyroid cancer due to a personal or family health history.
