Type 2 diabetes management means you control you blood sugar levels and prevent diabetes complications. Management will help you feel well and enjoy your daily activities.

What do I need to know about high blood sugar levels?

High blood sugar levels may not cause any symptoms. You may feel more thirsty or urinate more often than usual. Over time, high blood sugar levels can damage your nerves, blood vessels, tissues, and organs. The following can increase your blood sugar levels:

  • Large meals or large amounts of carbohydrates at one time
  • Less physical activity
  • Stress
  • Illness
  • A lower dose of diabetes medicine or insulin, or a late dose

What do I need to know about low blood sugar levels?

Symptoms include feeling shaky, dizzy, irritable, or confused. You can prevent symptoms by keeping your blood sugar levels from going too low.

  • Treat a low blood sugar level right away:
    • Drink 4 ounces of juice or have 1 tube of glucose gel.
    • Check your blood sugar level again 10 to 15 minutes later.
    • When the level goes back to normal, eat a meal or snack to prevent another decrease.
      Ways to Raise Your Blood Sugar
  • Keep glucose gel, raisins, or hard candy with you at all times to treat a low blood sugar level.
  • Your blood sugar level can get too low if you take diabetes medicine or insulin and do not eat enough food.
  • If you use insulin, check your blood sugar level before you exercise.
    • If your blood sugar level is below 100 mg/dL, eat 4 crackers or 2 ounces of raisins, or drink 4 ounces of juice.
    • Check your level every 30 minutes if you exercise longer than 1 hour.
    • You may need a snack during or after exercise.

What can I do to manage my blood sugar levels?

  • Check your blood sugar levels as directed and as needed. Several items are available to use to check your levels. You may need to check by testing a drop of blood in a glucose monitor. You may instead be given a continuous glucose monitoring (CGM) device. The device is worn at all times. The CGM checks your blood sugar level every 5 minutes. It sends results to an electronic device such as a smart phone. A CGM can be used with or without an insulin pump. You and your diabetes care team providers will decide on the best method for you. The goal for blood sugar levels before meals is between 80 and 130 mg/dL and 2 hours after eating is lower than 180 mg/dL.
    How to check your blood sugar
    Continuous Glucose Monitoring
  • Make healthy food choices. Work with a dietitian to develop a meal plan that works for you and your schedule. A dietitian can help you learn how to eat the right amount of carbohydrates during your meals and snacks. Carbohydrates can raise your blood sugar level if you eat too many at one time. Examples of foods that contain carbohydrates are breads, cereals, rice, pasta, and sweets.
    Plate Method
  • Eat high-fiber foods as directed. Fiber helps improve blood sugar levels. Fiber also lowers your risk for heart disease and other problems diabetes can cause. Examples of high-fiber foods include vegetables, whole-grain bread, and beans such as pinto beans. Your dietitian can tell you how much fiber to have each day.

  • Get regular physical activity. Physical activity can help you get to your target blood sugar level goal and manage your weight. Get at least 150 minutes of moderate to vigorous aerobic physical activity each week. Do not miss more than 2 days in a row. Do not sit longer than 30 minutes at a time. Your healthcare provider can help you create an activity plan. The plan can include the best activities for you and can help you build your strength and endurance.

  • Maintain a healthy weight. Ask your team what a healthy weight is for you. A healthy weight can help you control diabetes and prevent heart disease. Ask your team to help you create a weight loss plan, if needed. Weight loss can help make a difference in managing diabetes. Your team will help you set a weight-loss goal, such as 10 to 15 pounds, or 5% of your extra weight. Together you and your team can set manageable weight loss goals.
  • Take your diabetes medicine or insulin as directed. You may need diabetes medicine, insulin, or both to help control your blood sugar levels. Your provider will teach you how and when to take your diabetes medicine or insulin. You will also be taught about side effects oral diabetes medicine can cause. Insulin may be injected or given through a pump or pen. You and your providers will decide on the best method for you:
    • An insulin pump is an implanted device that gives your insulin 24 hours a day. An insulin pump prevents the need for multiple insulin injections in a day.

    • An insulin pen is a device prefilled with the right amount of insulin.
      Insulin Pen
    • You and your family members will be taught how to draw up and give insulin if this is the best method for you. Your providers will also teach you how to dispose of needles and syringes.
    • You will learn how much insulin you need and when to give it. You will be taught when not to give insulin. You will also be taught what to do if your blood sugar level drops too low. This may happen if you take insulin and do not eat the right amount of carbohydrates.

What else can I do to manage type 2 diabetes?

  • Wear medical alert identification. Wear medical alert jewelry or carry a card that says you have diabetes. Ask your provider where to get these items.
    Medical Alert Jewelry
  • Do not smoke. Nicotine and other chemicals in cigarettes and cigars can cause lung and blood vessel damage. It also makes it more difficult to manage your diabetes. Ask your provider for information if you currently smoke and need help to quit. Do not use e-cigarettes or smokeless tobacco in place of cigarettes or to help you quit. They still contain nicotine.
  • Check your feet each day for cuts, scratches, calluses, or other wounds. Look for redness and swelling, and feel for warmth. Wear shoes that fit well. Check your shoes for rocks or other objects that can hurt your feet. Do not walk barefoot or wear shoes without socks. Wear cotton socks to help keep your feet dry.
    Diabetic Foot Care
  • Ask about vaccines you may need. You have a higher risk for serious illness if you get the flu, pneumonia, COVID-19, or hepatitis. Ask your provider if you should get vaccines to prevent these or other diseases, and when to get the vaccines.
  • Talk to your provider if you become stressed about diabetes care. Sometimes being able to fit diabetes care into your life can cause increased stress. The stress can cause you not to take care of yourself properly. Your care team providers can help by offering tips about self-care. Your providers may suggest you talk to a mental health provider who can listen and offer help with self-care issues.
  • Have your A1c checked as directed. Your provider may check your A1c every 3 months, or 2 times each year if your diabetes is controlled. An A1c test shows the average amount of sugar in your blood over the past 2 to 3 months. Your provider will tell you what your A1c level should be.
  • Have screening tests as directed. Your provider may recommend screening for complications of diabetes and other conditions that may develop. Some screenings may begin right away and some may happen within the first 5 years of diagnosis:
    • Examples of diabetes complications include kidney problems, high cholesterol, high blood pressure, blood vessel problems, eye problems, and sleep apnea.
    • You may be screened for a low vitamin B level if you take oral diabetes medicine for a long time.
    • Women of childbearing years may be screened for polycystic ovarian syndrome (PCOS).

Have someone call your local emergency number (911 in the US) if:

  • You cannot be woken.
  • You have signs of diabetic ketoacidosis:
    • confusion, fatigue
    • vomiting
    • rapid heartbeat
    • fruity smelling breath
    • extreme thirst
    • dry mouth and skin
  • You have any of the following signs of a heart attack:
    • Squeezing, pressure, or pain in your chest

      • Discomfort or pain in your back, neck, jaw, stomach, or arm
      • Shortness of breath
      • Nausea or vomiting
      • Lightheadedness or a sudden cold sweat
  • You have any of the following signs of a stroke:
    • Numbness or drooping on one side of your face
    • Weakness in an arm or leg
    • Confusion or difficulty speaking
    • Dizziness, a severe headache, or vision loss
