What is considered high blood sugar?
High blood sugar, also called hyperglycemia, happens when glucose levels in your blood rise above normal ranges. For people with type 2 diabetes, high blood sugar is generally defined as:
* More than 180 mg/dL (10 mmol/L) one to two hours after eating
* Above your personal target range set by your healthcare provider
Normal blood sugar levels typically range from 70 to 140 mg/dL (3.9 to 7.8 mmol/L).
Why does it happen?
High blood sugar occurs when your body doesn't make enough insulin or your cells can't use insulin properly. Insulin acts like a key that helps glucose enter your cells for energy. Without enough insulin, sugar builds up in your bloodstream instead.
Common symptoms include:
* Extreme thirst and dry mouth
* Frequent urination
* Headaches
* Blurred vision
* Increased hunger
* Weakness or fatigue
* Confusion
Many people don't notice symptoms until blood sugar reaches 250 mg/dL or higher, which is why regular monitoring is so important.
If left untreated, high blood sugar can lead to serious complications affecting your eyes, nerves, kidneys, heart, and other organs. It's important to work with your healthcare team to keep your levels within your target range.
