Blood sugar levels tell us how much sugar is in the blood. This sugar is called glucose. Glucose is important for energy. But too much glucose can be dangerous. It can lead to serious health problems. This article discusses the highest blood sugar level ever recorded. We will also talk about its effects and how to manage it.
What is Blood Sugar?
Blood sugar is the amount of glucose in your blood. Our bodies use glucose for energy. We get glucose from the food we eat. Foods like bread, pasta, and fruits contain glucose. The body needs insulin to use glucose. Insulin is a hormone made by the pancreas. It helps move glucose into our cells.
High Blood Sugar: What is Hyperglycemia?
When blood sugar levels are too high, it is called hyperglycemia. This can happen when the body does not have enough insulin. It can also occur when the body cannot use insulin properly. Symptoms of high blood sugar include:
- Excessive thirst
- Frequent urination
- Fatigue
- Blurred vision
- Headaches
If blood sugar remains high, it can lead to serious problems. One severe condition is called diabetic ketoacidosis (DKA). DKA happens when the body produces high levels of ketones. Ketones are harmful acids. They can cause a diabetic coma, which can be life-threatening.

Record High Blood Sugar Levels
The highest blood sugar level ever recorded is shocking. Michael Patrick Buonocore, a young boy from Pennsylvania, holds this record. He had a blood sugar level of 2,000 mg/dL. This is extremely high. Normal blood sugar levels are between 70 and 130 mg/dL. His case is an example of severe hyperglycemia.
How Did This Happen?
Michael had type 1 diabetes. This means his body does not make insulin. Without insulin, his body could not use glucose. As a result, his blood sugar rose dangerously high. When he was taken to the hospital, he was very sick. Doctors acted quickly to help him.
