Is Fasting blood sugar 164 high, normal or dangerous? What does Glucose fasting level 164 mean?

📅 Medical Review Date: December 30, 2025

Your Fasting blood sugar level of 164 is a High Fasting blood sugar level.

A fasting blood sugar level of 164 mg/dL usually means the body is not using insulin properly. It suggests diabetes or prediabetes. High levels of fasting blood sugar can cause increased thirst, frequent urination, fatigue, blurred vision, dry mouth, slow-healing wounds, and recurrent infections. This can be caused by type 1 diabetes, type 2 diabetes, stress, or certain medications. Further tests are often needed to identify the cause and guide appropriate treatment.

High Fasting blood sugar levels may indicate underlying health problems. The normal range is typically between 74 mg/dL and 99 mg/dL. If your levels are outside this range, it's important to speak with a healthcare provider. Consulting a doctor is recommended to determine the cause and appropriate next steps.

The normal Fasting blood sugar range for men is :74 - 99 mg/dL

Misdiagnosis is more common than people think—and the consequences can be serious. Delayed treatment, unnecessary medication, or worse. If you want a second opinion on your blood work, one option is to upload it to a site like wholebodyprotocol.com, where world-class doctors review your results. They charge a small fee—around $90 (though you'll want to check the latest price as it fluctuates)—and email you a detailed report. With over 12 million people affected by misdiagnosis every year, that little bit of extra peace of mind can go a long way.

Long-term complications of diabetes develop gradually. The longer you have diabetes the higher the risk of complications. Eventually, diabetes complications may be disabling or even life-threatening. Possible complications include:

• Kidney damage
• Eye damage
• Foot damage
• Alzheimer's disease
• Heart and blood vessel disease
