Common Questions About Blood Sugar Levels

First off, it's important to understand that controlling your blood sugar in your day-to-day life with diabetes will basically involve a do-it-yourself process; having the tools you need ahead of time can help you figure out the best way to help control your condition.
Monitoring blood sugar levels will be the main tool you have to check your diabetes control. It will be necessary to check this level and record the results so your healthcare provider can determine how you are responding to your diabetes treatment plan.
Some of the questions you may want to ask your healthcare provider about monitoring your blood sugar include:
  • Is there a difference between blood sugar and blood glucose?
  • What are those blood sugar numbers all about?
  • How often should I check my blood sugar levels?
  • Are there specific times during the day I should test my blood sugar?
  • What is low blood sugar and high blood sugar?
  • What should I do if my blood sugar is too high or too low? How can I prevent this from happening?
  • What is early-morning blood sugar (FPG)?
  • What is after-meal blood sugar (PPG)?
  • What are my goals for measuring my blood sugar on a daily basis?
  • What are the symptoms of low blood sugar and high blood sugar?
  • How do I manage my diabetes while traveling?
  • If I can control my blood sugar levels, does that mean my type 2 diabetes is cured?
By monitoring your blood sugar levels, you can tell how you react to different foods, stresses, illnesses, and exercise. It also helps you to monitor whether you are having problems with high or low levels at certain times during the day, potentially indicating that you need to adjust your medicine or other lifestyle habits.
For your regular checkups, it can help to bring a book that contains all your daily recorded blood sugar levels. This will help give your healthcare provider a good picture of your body's response to certain lifestyle changes and medications (if you are taking any). After checking your blood sugar level, write down your results and review them to see how food, activity, and stress may have affected these levels. This record can help you see if your levels are too high or too low several days in a row at about the same time of day.
Another test that your healthcare provider will order for monitoring your type 2 diabetes is an A1c test (also known as a hemoglobin A1c or HbA1c test). This blood test measures long-term blood sugar control. It basically helps give an average of your blood sugar levels over a period of about three months.
Some of the questions you may want to discuss with your healthcare provider regarding the A1c test include:
  • Why is my A1c important?
  • What is the goal number for my A1c?
  • How often should I get my A1c tested?
  • What can I do to help lower my A1c?
  • Is there any special preparation I should know about before I have an A1c test? Do I need to fast?
