Frequently Asked Questions 

About Diabetes

  1. How often should I check my blood sugar?

    Blood sugar monitoring is an essential part of a good diabetes management plan. The American Diabetes Association (ADA) suggests the following blood glucose targets for most adults: 80-130 mg/dL before a meal, and less than 180 mg/dL 1-2 hours after the start of a meal.* Ask your doctor how often to check your blood sugar and what times of the day would be best for you to test.

  2. What is my HbA1c? 

    HbA1c is a test that provides information about your average blood sugar level over a period of time (approximately 2 to 3 months). Tight blood sugar control would be reflected in a level of less than 7%. 

  3. How can I learn more about diabetes? 

    Research is always changing, so it's important to continue to learn more about your diabetes. Ask your doctor if there are any diabetes classes offered locally, such as at a hospital, that you could attend. If you want to study more about diabetes, you can visit this site.

  4. What is a healthy weight for me? 

    For those with diabetes, losing weight can help lower blood pressure, improve blood cholesterol levels, and improve blood sugar control. Weight loss might even help you reduce some of your medications. Consult a healthcare professional to find out your healthy weight. 

  5. Why should I choose sucrose-free products? 

    Sucrose-free food products may benefit people with diabetes by supporting weight and glucose management. While it is sucrose-free, Glucerna® is nutritious and delicious. It is specially formulated to be low in Glycemic index (GI) with a unique, slow-release carbohydrate blend that includes diabetes-friendly ingredients such as Fibersol-2, sucromalt, maltitol, fructose, isomaltulose, FOS, and oat fiber. 

  6. How much should I eat? 

    The number of calories and carbohydrates recommended for meals and snacks varies among individuals depending on several factors, including age, sex, weight, activity level, health conditions, and any diabetes medications you might be taking. Your doctor can recommend a calorie level that meets your individual nutritional needs and might also have meal plans or other diet information that you can take home with you. 

  7. I have recently been diagnosed with Type 2 Diabetes Mellitus (T2DM). Is T2DM reversible? How do I stay in better control of my glucose levels? 

    Type 2 diabetes, the most common type of diabetes, is brought on by age, genetics (seen in the family history), and environmental influence - the biggest of which is overweight or obesity. Understanding this, type 2 diabetes is reversible when overweight, and obesity contributes significantly. Knowing your BMI can help you set a weight loss goal, and determine if you need to lose weight or how much of it you need to lose. Control of blood glucose requires a 3-prong approach of  
    • Watching your diet,
    • Reducing weight if overweight through diet and exercise, and
    • Following your doctor's advice in taking medication
  8. Is there a recommended diet for people with T2DM? Do I need to stop taking carbohydrates or sugary food? 

    Generally, the recommended diet for diabetes is to be mindful of the food that can raise blood glucose levels. These are in the form of sugary food, fruits, and starchy carbohydrates. The idea is not to stop taking carbohydrates or fruits but to reduce the amount, choose low glycemic index carbohydrates, incorporate fiber and combine with vegetables and protein in the diet. Sugary food should be avoided when blood glucose levels are high and not well controlled, but they can be incorporated into the diet when the control is better. Diet is to be balanced with physical activity and regular exercise. Seeing a dietitian for individualized advice is important. 

Glucerna® and diabetes

  1. I am overweight and have T2DM. How can losing weight help me better manage my condition? Would a diabetes-specific formula like Glucerna® help me with losing weight?

    Besides genetics and age, type 2 diabetes is driven by being overweight, the biggest environmental influence on the condition. Being overweight makes the body less efficient in its use of insulin which is the hormone that lowers blood glucose levels. Regular exercise and losing weight increase the body's efficiency in using insulin to lower blood glucose levels. Both actions help a person reduce reliance on medication to control the condition. Diabetes-friendly meal replacements like Glucerna® can be used in conjunction with a doctor's or dietitian's advice to substitute a higher calorie meal or snack. If done regularly and consistently, together with an overall diet plan and regular exercise and physical activity, this can help a person lose weight. 

  2. How can Glucerna® help me manage diabetes?

    The new Glucerna® is Abbott’s most advanced diabetes nutrition formula to complement your diabetes care plan. Glucerna® is scientifically formulated to support diabetes management. It now has four times higher inositol* which helps the body convert sugar into energy and remains low Glycemic Index (GI)8 with an advanced slow-release carbohydrate blend and a unique dual fiber blend of oat and FOS, that helps the body produce insulin naturally.

Product-related questions

  1. What are low-glycemic carbohydrates?

    Low-glycemic carbohydrates – those with a low glycemic index – are processed more slowly by our digestive system and so cause a lower and slower rise in blood glucose5. Glucerna® contains a blend of carbohydrates that are low glycemic.. Together, this combination of carbohydrates produces a lower blood glucose response than higher-glycemic carbohydrates.2 Refer to the Glucerna® product label for specific ingredient information.

  2. Are Glucerna® products a good choice for low blood sugar (hypoglycemia)?

    For people with or without diabetes, Glucerna® products should not be used to treat hypoglycemia, insulin shock, or insulin reaction because the carbohydrates in Glucerna® are not absorbed quickly enough to restore blood glucose to a normal level fast enough. Talk to your healthcare professional about appropriate treatment options for low blood glucose episodes

  3. What is the glycemic index of Glucerna®?

    Glucerna® has a low glycemic index (GI): Vanilla powder (mixed with water) has a GI of 35, Chocolate powder (mixed with water) has a GI of 29, Wheat powder (mixed with water) has a GI of 38, and the 200 ml Ready-to-Drink Glucerna® has a GI of 271

  4. Do Glucerna® products contain lactose?

    All of our Glucerna® products contain a maximum of 24 mg of lactose per serving. Compared to a glass of milk, which has 10,000 mg to 12,000 mg of lactose per serving, the amount of lactose in Glucerna® is very low. Therefore, Glucerna® is suitable for people with lactose intolerance.

  5. Do you recommend Glucerna® products for diabetes and chronic renal failure patients?

    The decision to use Glucerna® products for anyone with chronic kidney disease (CKD) ultimately rests with the nephrologist/healthcare professional, who will assess the patient’s needs individually.

  6. Have any scientific studies been done to support Glucerna®’s claims?

    Yes. Glucerna® has been studied for over 30 years in more than 59 clinical studies, with more than 4,800 individuals.

Unlike regular milk, Glucerna® is low in lactose, cholesterol-free, and trans-fat-free.

  8. When do I use Glucerna® as a meal replacement or as part of a meal?

    Glucerna® as a meal replacement works best if you aim to shed weight. When used to replace a typical local meal, Glucerna® can provide fewer calories while providing complete & balanced nutrition. If you aim to maintain weight but achieve better diabetes management, you may substitute a part of your meal with Glucerna®. Consult your dietitian for further advice.

  9. Can Glucerna® be used by people without diabetes?

    It is safe for someone without diabetes to consume Glucerna®. However, Abbott Nutrition has many other options, such as Ensure®, for people without diabetes to integrate into their meal plans.
