With that being said, managing high blood sugar and knowing the signs of when it spikes is essential to controlling diabetes.

What is High Blood Sugar?

High Blood Sugar

High blood sugar, also known as hyperglycemia happens when a build-up of excess glucose occurs in the bloodstream. This can happen for people who don’t suffer from diabetes but is more occurrent in those who already have diabetes.

A lot of people think eating a lot of sugar and sweet foods is the main cause of the spike in blood sugar levels. Although this is true to an extent, it isn’t the only factor. 

Insulin, created in the pancreas helps to move glucose through the body. When type-2 diabetes is an existing factor in your health, your body will not produce enough insulin to help move the glucose in your body and will build-up glucose in the bloodstream. 


When blood sugar levels spike to alarming levels, ketoacidosis and ketosis will occur. 

Ketoacidosis can occur in people with diabetes and must be treated as an emergency and taken with immediate action. Diabetic ketoacidosis can cause your blood to become very acidic and can result in death or diabetic coma if it rises to alarming levels.

Ketosis more commonly occurs in people who don’t have diabetes. Ketoacidosis is very unlikely to occur in people who don’t have diabetes as their bodies can still supply enough insulin to manage glucose levels. 

It’s also important to understand the difference between ketoacidosis and ketosis.
