Can Antibiotics Raise Blood Sugar Levels?
The answer is yes. Some antibiotics can raise blood sugar levels. This includes a type called fluoroquinolones. Examples are:
- Ciprofloxacin
- Levofloxacin
- Moxifloxacin
These antibiotics may cause both high and low blood sugar. This can be a problem for people with diabetes.
Why Do Antibiotics Affect Blood Sugar?
When you are sick, your body reacts. It releases hormones. These hormones can raise blood sugar. Antibiotics can also change how your body processes sugar.
Here are some reasons why antibiotics affect blood sugar:
- Infection causes stress. Stress raises blood sugar.
- Some antibiotics can change gut bacteria.
- Gut bacteria affect sugar metabolism.
When You Are Sick
When you are sick, your blood sugar may rise. The body releases more glucose. This happens even if you have not eaten. Stress hormones like cortisol play a role. They increase sugar in the blood.
What Should You Do?
If you take antibiotics and have diabetes, watch your blood sugar closely. Here are some tips:
- Check your blood sugar regularly.
- Keep a record of your levels.
- Talk to your doctor about changes.
Other Factors That Affect Blood Sugar
