Covid-19 is a virus that affects many people. It can cause many health problems. One concern is its effect on blood sugar levels. This article will explain how Covid can raise blood sugar.
Understanding Blood Sugar
Blood sugar is the amount of glucose in your blood. Glucose comes from the food we eat. Our body uses it for energy. For people with diabetes, managing blood sugar is very important. High blood sugar can cause serious health issues.
How Does Covid Affect Blood Sugar?
When you get sick, your body reacts. It sees the virus as a threat. The body releases stress hormones. These hormones help fight the infection. However, they can also raise blood sugar levels.
Stress Response
When you are ill, your body releases hormones like:
- Epinephrine (adrenaline)
- Cortisol
These hormones have two main effects:
- They signal the liver to release stored glucose.
- They make the body’s cells less responsive to insulin.
This can cause blood sugar levels to rise. For people with diabetes, this is especially concerning.
Covid And Diabetes
Some people have diabetes before getting Covid. They need to monitor their blood sugar closely. If they do not, their levels can rise dangerously high. This can lead to complications.
People with diabetes are more likely to get severe Covid. It is essential for them to manage their health during this time.

This effect is temporary but significant for those with diabetes. Monitoring blood sugar closely during illness is crucial for managing health effectively.
At What Blood Sugar Level Should I Go To The Hospital?
Seek immediate medical attention if your blood sugar exceeds 300 mg/dL and you experience symptoms like confusion or fruity breath. Also, go to the hospital if you exhibit signs of hypoglycemia, such as dizziness or loss of consciousness. Always prioritize your health and safety.
Does Viral Infection Increase Blood Sugar?
Yes, viral infections can increase blood sugar levels. The body releases stress hormones like cortisol and adrenaline, which raise glucose production and reduce insulin sensitivity. This response is a natural reaction to illness. Monitoring blood sugar is vital, especially for those with diabetes during infections.
Can Long Covid Affect Blood Sugar Levels?
Yes, long COVID can affect blood sugar levels. Some individuals experience insulin resistance and hormonal changes, leading to elevated glucose levels.
