GLP-1 Side Effects: What You Should Know and How to Manage Them

Feeling icky? Let’s work on that. We explain the most common side effects of GLP-1 medications, and provide practical tips on how to manage them.

When starting GLP-1 medications, such as semaglutide or tirzepatide, many individuals experience a significant improvement in weight management and overall health. However, just like any medication, GLP-1s can cause side effects. These side effects are usually temporary and diminish as your body adjusts, but it’s important to be aware of them and know how to manage them for the best results.

In this blog, we’ll explore the most common side effects of GLP-1 medications, like nausea and digestive issues, and provide practical tips on how to manage them. We’ll also explain when it’s time to contact a healthcare provider.

Common Side Effects of GLP-1 Medications

GLP-1 medications work by regulating appetite, improving blood sugar levels, and supporting weight loss. While these benefits are significant, the medications can sometimes lead to side effects, especially in the first few weeks of treatment. Here are some of the most common side effects and how to manage them:

1. Nausea

One of the most frequently reported side effects of GLP-1 medications is nausea. This occurs because GLP-1s slow down gastric emptying, causing food to stay in the stomach longer. For some, this can lead to a feeling of fullness or discomfort.

How to manage nausea:

• Start with a lower dose: Most GLP-1 medications start at a low dose that is gradually increased. This approach allows your body to adjust, minimizing nausea.
• Eat smaller, more frequent meals: Smaller meals are easier to digest and may help reduce nausea.
• Stay hydrated: Sipping water or herbal teas can help soothe the stomach and reduce feelings of nausea.
• Avoid greasy or spicy foods: These can exacerbate nausea, so opt for bland, easy-to-digest foods during the adjustment period.

If nausea persists after a few weeks, consult your weight management doctor to discuss dosage adjustments or alternative treatments.

2. Digestive Issues (Constipation, Bloating, and Gas)

GLP-1 medications can affect digestion, leading to issues like constipation, bloating, and gas. The slowing of gastric emptying is beneficial for appetite control but can sometimes interfere with normal digestive processes.

How to manage digestive issues:

• Increase fiber intake: Foods like fruits, vegetables, and whole grains can help prevent constipation and promote healthy digestion.
• Drink plenty of water: Staying hydrated is essential for preventing constipation and supporting digestive health.
• Stay active: Regular physical activity can stimulate bowel movements and help relieve bloating.
• Gradually introduce changes to your diet: Making sudden changes to your diet can overwhelm your digestive system. Slowly increase fiber and avoid overeating.

If constipation or bloating persists, talk to your healthcare provider about possible adjustments or remedies.

3. Loss of Appetite

While GLP-1 medications are designed to suppress appetite, some individuals may find that they no longer feel hungry or may have difficulty eating enough. While this can be beneficial for weight loss, it’s important to ensure you’re still getting the nutrition your body needs.

How to manage loss of appetite:

• Focus on nutrient-dense foods: When you do eat, prioritize meals that are rich in protein, healthy fats, and fiber to keep you full and nourished.
• Eat smaller meals more frequently: Eating smaller portions throughout the day can ensure you’re meeting your nutritional needs without overwhelming your appetite.
• Consider meal planning: Prepare meals in advance to make eating easier, especially if your appetite fluctuates throughout the day.

If you experience significant difficulty eating or maintaining your weight, consult your weight management physician to discuss alternative strategies.

Less Common Side Effects of GLP-1 Medications

In addition to the common side effects mentioned above, some people may experience less common side effects. These can include:

1. Headache

Some individuals on GLP-1 medications may experience headaches as a side effect. This could be due to dehydration, changes in blood sugar levels, or the medication itself.

How to manage headaches:

• Stay hydrated: Dehydration can worsen headaches, so make sure you’re drinking enough water throughout the day.
• Take over-the-counter pain relievers: Consult your healthcare provider for recommendations on safe pain relievers while on GLP-1 therapy.

2. Fatigue

Fatigue or tiredness can occur as your body adjusts to GLP-1 medications. This can be particularly noticeable during the first few weeks of treatment.

How to manage fatigue:

• Ensure you’re getting enough sleep: A consistent sleep schedule can help manage feelings of tiredness.
• Eat balanced meals: Fueling your body with the right nutrients can help maintain your energy levels.
• Start slow with exercise: Gradual physical activity can help improve energy levels over time.

3. Injection Site Reactions (for injectable GLP-1s)

For those using injectable GLP-1 medications like Wegovy or semaglutide, mild reactions at the injection site (redness, swelling, or irritation) can occur.

How to manage injection site reactions:

• Rotate injection sites: Avoid injecting into the same spot each time to minimize irritation.
• Apply a cold compress: A cold pack can help reduce swelling or irritation at the injection site.

When to Contact Your Healthcare Provider

While most side effects of GLP-1 medications are temporary and manageable, there are some situations where it’s important to contact your healthcare provider:

1. Severe or persistent nausea: If nausea doesn’t improve after a few weeks or becomes severe, it could be a sign that the dosage needs to be adjusted.
2. Persistent digestive issues: If constipation, bloating, or gas doesn’t improve with lifestyle changes, your healthcare provider may recommend alternative treatments or remedies.
3. Signs of dehydration: If you experience excessive thirst, dry mouth, or dizziness, you may be dehydrated, especially if nausea or vomiting is present.
4. Unexplained weight loss: If you experience excessive weight loss that concerns you, consult your weight management physician to ensure you’re on the right treatment plan.
5. Serious allergic reactions: Although rare, some individuals may have an allergic reaction to GLP-1 medications. Seek immediate medical attention if you experience difficulty breathing, swelling, or a rash.

Conclusion

GLP-1 medications are an effective tool for weight management and weight loss, but like any medication, they can come with side effects. Most side effects, such as nausea, digestive issues, and loss of appetite, are temporary and manageable. By making small adjustments to your diet, staying hydrated, and being mindful of your body’s signals, you can successfully navigate the early stages of GLP-1 therapy.

If you experience persistent or severe side effects, don’t hesitate to reach out to your weight management doctor for guidance and support. Remember, managing side effects is part of the process, and with the right approach, you can achieve lasting success in your weight management journey.
