Home blood sugar monitoring when you have gestational diabetes

Introduction

If you have gestational diabetes, you need to know when your blood sugar level is outside the safe range. Fortunately, you can see what your blood sugar level is anywhere and anytime by using a home blood sugar meter. Within a minute or two, you can know what your blood sugar level is.

Key points

• Knowing your blood sugar level helps you treat low or high blood sugar before it becomes an emergency.
• Knowing your blood sugar level also helps you know how exercise and food affect your blood sugar and how much insulin to take (if you take insulin).
• Checking your blood sugar helps you feel more in control of your diabetes during your pregnancy.
• Four keys to success in monitoring your blood sugar are:
  • Keeping your meter and supplies with you at all times.
  • Making it a habit to check your blood sugar level by building it into your routine.
  • Pricking the sides of your fingers, not the tips. The tip of a finger is more sensitive than its sides.
  • Checking your blood sugar meter's accuracy when you visit your doctor by comparing your results with your doctor's results.

What is home blood sugar monitoring?

Although your doctor will check your blood sugar level during your visits, you need to know what your blood sugar level is every day. You can know what your blood sugar level is at any time by using a home blood sugar meter. This is often referred to as home blood sugar monitoring or self-testing. Your doctor may want you to check your blood sugar level 4 to 6 times a day. You will also need to test your blood sugar if you feel faint, dizzy, or unusually tired.

To test your blood sugar level using a blood sugar meter, prick your finger with a small needle called a lancet to collect a drop of blood. Place the drop of blood on a test strip and put the strip into your meter. (For some meters, the test strip is put into the meter before the blood is applied.) Within a few seconds to 2 minutes, the meter shows the results of your test.

Test Your Knowledge

Why monitor your blood sugar?

Monitoring your blood sugar level at home helps put your mind at ease by helping you:

• Know when your blood sugar is low. Most women who have gestational diabetes do not experience dangerously low blood sugar levels. If your blood sugar drops just below your safe level and you quickly eat something that contains sugar, your blood sugar will not drop to a level that is dangerous for you and your baby.
• Know when your blood sugar is high. Frequent high blood sugar levels may lead to high blood pressure, your baby growing too large to be delivered naturally, and your baby having low blood sugar levels (hypoglycemia).
• Know what your blood sugar level is before a meal. If you take insulin, you can use your results to determine how much insulin to take.
• Know how exercise affects your blood sugar. Exercise usually lowers your blood sugar level.
• Know what your blood sugar is when you are sick. Severe illness or stress usually causes higher-than-normal blood sugar levels.
• Know when the foods you eat or the amount of insulin you take (if you take insulin) need to be adjusted.

Test Your Knowledge

1. Home blood sugar monitoring helps you know how exercise has affected your blood sugar.
1. True
   

   The answer is correct

   Home blood sugar monitoring does help you know how exercise has affected your blood sugar. Checking your blood sugar after exercising will help you know whether your blood sugar levels are staying within a safe range.

   
2. False
   

   The answer is incorrect

   Home blood sugar monitoring does help you know how exercise has affected your blood sugar. Checking your blood sugar after exercising will help you know whether your blood sugar levels are staying within a safe range.

How to test your blood sugar

Here is a simple way to monitor your blood sugar at home.

Get organized

Before you start testing your blood sugar:

• Talk with your doctor about how often and when you should test. Record this information on the blood sugar testing times form(What is a PDF document?).
• Link testing your blood sugar with other daily activities, such as preparing breakfast. This will help you establish the habit of self-testing.
• Use the list of supplies to gather the things you need to test your blood sugar. Keep your supplies together so that you can do a test quickly if you need to.
• Check your equipment before doing each test.
  • Check the expiration date on your testing strips. If you use test strips after the expiration date, you may not get accurate results.
  • Make sure the code numbers on the testing strips bottle match the numbers on your meter. If the numbers do not match, follow the directions that come with your meter for changing the code numbers.
  • Check the accuracy of your meter's results. Use the sugar control solution made by your meter's manufacturer. Follow the directions that came with your meter for using the control solution.
• Take care of your equipment. Put a copy of the care of blood sugar supplies with your bag or kit to remind you.

Do the test

The more often you test your blood sugar, the more you will know about how well your treatment is working.

Follow these steps when you test your blood sugar:

1. Wash your hands with warm soapy water and dry them well with a clean towel.
2. Put a clean needle (lancet) in the lancet device. The lancet device is a pen-sized holder for the lancet. It holds and positions the lancet and controls how deeply the lancet goes into your skin.
3. Get a test strip from your bottle of testing strips. Put the lid back on the bottle immediately to prevent moisture from affecting your other strips.
4. Get your blood sugar meter ready. Follow the manufacturer's instructions for your specific meter.
5. Use the lancet device to stick the side of your fingertip with the lancet.
6. Put a drop of blood on the correct spot of the test strip, covering the test area well.
7. Using a clean cotton ball, apply pressure to the place where you stuck your finger to stop the bleeding.
8. Wait for the results. Some meters take only a few seconds to give you the results.

Record the results

Recording your blood sugar results is very important. Your doctor will use this record to see how well your treatment is working and to know if anything needs to be changed. Be sure to take your record with you on each visit to your doctor or diabetes educator.

To record your results, you can:

• Get printed blood sugar logs from companies that make diabetic medications and supplies.
• Make a blood sugar log in a notebook. You can record other information in the log or notebook, such as insulin doses, your exercise, and what you have eaten.
• Use your blood sugar meter, if possible. Some blood sugar meters can store blood sugar results and some can calculate your average blood sugar for a period of time, such as over a day or a week.

Preventing sore fingers

Your fingertips may get sore from testing your blood sugar so often. Here are some tips to help prevent sore fingers.

• Do not prick the tip of your finger. It is more painful and harder to get enough blood to do the test accurately. Also, do not prick your toes because your feet can become infected.
• Don't squeeze your fingertip. If you have trouble getting a drop of blood large enough to cover the test area of the strip, hang your hand down below your waist and count to 5, or place your finger in warm water for a minute or so.
• Use a different finger each time. Establish a pattern for which finger you stick so that you will not use some fingers more than others. Avoid any fingers that are sore for a few days.
• Use a different device. Some new blood sugar meters use lancet devices that can get a blood sample from sites other than the fingers, such as the forearm. If you are having trouble with sore fingers, you may want to get one of these new meters.

Test Your Knowledge

1. To test your blood sugar, you need to put a drop of blood on the test strip used with your home blood sugar meter.
1. True
   

   The answer is correct
