How Much Does Metoprolol Raise Blood Sugar?
Metoprolol is a commonly prescribed medication for the treatment of high blood pressure, angina, and heart failure. However, like all medications, it can have side effects, including an impact on blood sugar levels. As a beta blocker, metoprolol can raise blood sugar levels in some individuals. In this article, we will explore how much metoprolol can raise blood sugar and who may be affected.
What is Metoprolol?
Metoprolol is a medication that belongs to the class of beta blockers. It works by blocking the action of epinephrine (adrenaline), a hormone that can stimulate the heart and increase blood pressure. By blocking epinephrine, metoprolol slows down the heart rate and reduces the force of the heart’s contractions, which in turn lowers blood pressure.
How Does Metoprolol Affect Blood Sugar?
Metoprolol can raise blood sugar levels by:
- Reducing insulin secretion: Metoprolol can decrease the release of insulin from the pancreas, leading to higher blood sugar levels.
- Increasing glucose absorption: Metoprolol can increase the absorption of glucose from the bloodstream into the liver, leading to higher blood sugar levels.
- Disrupting glucose metabolism: Metoprolol can disrupt the body’s natural glucose metabolism, leading to higher blood sugar levels.
How Much Does Metoprolol Raise Blood Sugar?
Studies have shown that metoprolol can raise blood sugar levels by varying amounts depending on the individual and the dose of the medication. Here are some findings:
- A study published in the Journal of Clinical Endocrinology and Metabolism found that metoprolol increased blood sugar levels by an average of 10-20% in healthy individuals.
- Another study published in the European Journal of Clinical Pharmacology found that metoprolol increased blood sugar levels by an average of 15-30% in patients with type 2 diabetes.
- A review of 17 studies on beta blockers and blood sugar levels found that metoprolol increased blood sugar levels by an average of 10-25%.
Who May Be Affected by Metoprolol’s Impact on Blood Sugar?
Metoprolol’s impact on blood sugar levels may be more significant in certain individuals, including:
- Diabetics: Individuals with type 1 or type 2 diabetes may be more susceptible to metoprolol’s impact on blood sugar levels.
- Older adults: Older adults may be more sensitive to the effects of metoprolol on blood sugar levels.
- Individuals with impaired glucose tolerance: Individuals with impaired glucose tolerance may be more likely to experience higher blood sugar levels with metoprolol.
Monitoring Blood Sugar Levels
If you are taking metoprolol, it is essential to monitor your blood sugar levels regularly to ensure that they remain within a healthy range. You can do this by:
- Monitoring your blood sugar levels at home: Use a glucometer to check your blood sugar levels at home.
- Working with your healthcare provider: Work with your healthcare provider to adjust your medication regimen and monitor your blood sugar levels.
Conclusion
Metoprolol can raise blood sugar levels in some individuals, particularly those with diabetes, older adults, and those with impaired glucose tolerance. While the increase in blood sugar levels may be modest, it is essential to monitor blood sugar levels regularly to ensure that they remain within a healthy range. If you are taking metoprolol, talk to your healthcare provider about the potential impact on your blood sugar levels and develop a plan to manage your blood sugar levels.

|---|---|
| Journal of Clinical Endocrinology and Metabolism | 10-20% |
| European Journal of Clinical Pharmacology | 15-30% |
| Review of 17 studies | 10-25% |
