What should I watch for?
Visit your health care professional or doctor for regular checks on your progress.
A test called the HbA1C (A1C) will be monitored. This is a simple blood test. It measures your blood sugar control over the last 2 to 3 months. You will receive this test every 3 to 6 months.
Learn how to check your blood sugar. Learn the symptoms of low and high blood sugar and how to manage them.
Always carry a quick-source of sugar with you in case you have symptoms of low blood sugar. Examples include hard sugar candy or glucose tablets. Make sure others know that you can choke if you eat or drink when you develop serious symptoms of low blood sugar, such as seizures or unconsciousness. They must get medical help at once.
Tell your doctor or health care professional if you have high blood sugar. You might need to change the dose of your medicine. If you are sick or exercising more than usual, you might need to change the dose of your medicine.
Make sure that you have the right kind of syringe for the type of insulin you use. Try not to change the brand and type of insulin or syringe unless your health care professional or doctor tells you to. Switching insulin brand or type can cause dangerously high or low blood sugar. Always keep an extra supply of insulin, syringes, and needles on hand. Use a syringe one time only. Throw away syringe and needle in a closed container to prevent accidental needle sticks.
Insulin pens and cartridges should never be shared. Even if the needle is changed, sharing may result in passing of viruses like hepatitis or HIV.
Wear a medical ID bracelet or chain, and carry a card that describes your disease and details of your medicine and dosage times.
