Blood Sugar Chart

Diabetes is a condition where success of treatment depends on how well you keep your blood sugar controlled. Good self-management can help improve both short and long term health outcomes(1). Use Medindia's 'Blood Sugar Calculator' and its resources, if you have recently been diagnosed to have diabetes. It will help you with self-education and better management of your health(2). Over a period of time you will learn how to manage the condition yourself and will understand why your sugar level fluctuates.

The Blood sugar chart provides descriptions of blood sugar values in terms of mg/dl depending on the test type – Fasting sugar, post-meal or post prandial and Glucose tolerance test (GTT) for a normal person, in early diabetes and in established diabetes. Use this chart to monitor your blood sugar level.

Important Facts About Blood Sugar

  • Glucose is a simple sugar and is one of the primary molecules which serve as energy sources for both plants and animals(3).
  • Insulin, a hormone produced by the pancreas, helps maintain normal blood sugar levels(4).
  • Uncontrolled or high blood sugar levels can lead to health complications such as blindness, heart disease and kidney disease(5).
  • Increase or decrease in the glucose level in the blood can lead to a condition called "diabetic coma"(6).

You are doing great work! Thanks for sharing this. People need to check their blood sugars levels daily so they know if treatments are working!

My sister had a Diabetic attack at the lake this weekend. Her blood sugar spiked to 421. We didn't realize that it was her diabetes at first. I'd like to know how to help her next time if this were to happen again. How can we bring her blood sugars down quickly until help arrives? We were able to get her help in time, but I'm so afraid that next time may be too late. Thank you!
