Many people take antibiotics to fight infections. But, do you know that antibiotics can affect blood sugar? This article will help you understand how antibiotics and blood sugar relate. We will also discuss which antibiotics may cause these changes.
What Are Antibiotics?
Antibiotics are medicines that kill bacteria. They help treat infections. Doctors often prescribe them for illnesses like strep throat or pneumonia. However, not all infections need antibiotics. Some infections heal on their own. Using antibiotics when not needed can cause problems.

How Do Antibiotics Affect Blood Sugar?
Some antibiotics can raise blood sugar levels. This is important for people with diabetes. High blood sugar can make them feel unwell. It can also lead to serious health problems. Let’s look at some antibiotics known to affect blood sugar.
Fluoroquinolones
Fluoroquinolones are a type of antibiotic. They include:
- Ciprofloxacin
- Levofloxacin
- Moxifloxacin
These antibiotics can cause both high and low blood sugar. The U.S. Food and Drug Administration (FDA) has warned about this. They say it can be very serious. In some cases, low blood sugar can lead to coma. It is especially risky for people with diabetes.
Other Antibiotics
Some studies show other antibiotics may also raise blood sugar. These include:
- Macrolides
- Cephalosporins
These antibiotics may be linked to a higher risk of diabetes. More research is needed to understand this fully. But, it is a concern for those who take them.
The Role of Gut Bacteria
Antibiotics change the bacteria in our gut. Our gut bacteria help us digest food. They also play a role in blood sugar control. When antibiotics disrupt this balance, it can lead to problems. This may increase the risk of diabetes.
Why Is This Important for Diabetics?
If you have diabetes, you should be careful with antibiotics. Here are some important tips:
- Talk to your doctor before starting any antibiotic.
- Monitor your blood sugar levels closely.
- Watch for signs of high or low blood sugar.
Being aware of these factors can help you stay healthy.
