Diabetes Index: Is Medication Necessary for Mild Cases? - Internal Medicine

What is the diabetes index?


Hello, Director Hsiao: My mother is 72 years old.
During her health check this year, her blood sugar level was found to be 130, while the normal upper limit is 110.
However, the doctor said it is still mild and that she does not need medication, just dietary management.
Is this true? If medication is required, will she need to continue taking it even if her levels return to normal? Additionally, what dietary restrictions should she follow? Should she avoid fruits? I would greatly appreciate your clarification on these matters!

Hello: In response to your questions.
1.
The normal fasting plasma glucose level for healthy individuals is between 70 to 100 mg/dL, and the postprandial glucose level two hours after a meal should be between 80 to 140 mg/dL.
A fasting plasma glucose level of 130 mg/dL after 8 hours is indeed slightly elevated; if subsequent tests at different times still show levels greater than the WHO-revised standard of 126 mg/dL from 1998, it can be classified as diabetes.
2.
The treatment for diabetes primarily includes diet, exercise, and medication; not all patients require medication.
In terms of diet, it is important to avoid high-cholesterol and high-fat foods, limit processed foods, and focus on a natural, high-fiber diet.
Fruits are also recommended.
Additionally, the total daily caloric intake should be regulated.
Regarding exercise, if there has not been a consistent routine, starting with 30 to 60 minutes of walking each day is advisable.
3.
Since diabetes management involves adjustments to lifestyle and dietary habits, and the choice of medication interacts with these factors, it is best to discuss this with your family physician first.

Hello! Thank you for your inquiry regarding diabetes management, particularly in mild cases. It's great to see that you are taking an active interest in your mother's health, especially considering her recent diagnosis.
To begin with, a blood glucose level of 130 mg/dL, especially when measured in a fasting state, does indicate that your mother is in the prediabetes range. The American Diabetes Association (ADA) defines prediabetes as a fasting blood glucose level between 100 mg/dL and 125 mg/dL. A level of 130 mg/dL suggests that her blood sugar is elevated but not yet in the diabetic range, which is defined as 126 mg/dL or higher on two separate tests.

In mild cases of elevated blood glucose, such as prediabetes, lifestyle modifications are often the first line of defense. This includes dietary changes, increased physical activity, and weight management. Many healthcare providers will recommend these lifestyle changes before considering medication. The rationale is that lifestyle interventions can significantly improve insulin sensitivity and help regulate blood sugar levels without the need for pharmacological treatment.

Regarding your question about medication: if your mother’s blood glucose levels improve through diet and exercise, she may not need to start medication. However, if her levels remain elevated or worsen, her healthcare provider may recommend medication such as Metformin, which is commonly prescribed for managing blood sugar levels in type 2 diabetes. It’s important to note that if medication is initiated, it is typically continued even if blood sugar levels normalize, as it helps maintain that control and prevent future complications.

As for dietary considerations, it’s essential to focus on a balanced diet that emphasizes whole foods. Here are some general guidelines:
1. Carbohydrate Management: Carbohydrates have the most significant impact on blood sugar levels. It’s advisable to choose complex carbohydrates (like whole grains, legumes, and vegetables) over simple sugars (like candy, pastries, and sugary drinks).
2. Fruits: Fruits are nutritious and can be part of a healthy diet. However, portion control is key. Some fruits have a higher glycemic index (GI) than others, meaning they can raise blood sugar levels more quickly. For example, bananas and grapes have a higher GI compared to berries and apples. It’s best to consume fruits in moderation and pair them with protein or healthy fats to help stabilize blood sugar levels.

3. Healthy Fats and Proteins: Incorporate sources of healthy fats (like avocados, nuts, and olive oil) and lean proteins (like chicken, fish, and legumes) into meals. These can help keep you full and reduce the likelihood of blood sugar spikes.

4. Regular Meals: Encourage regular meal times and avoid skipping meals, as this can lead to fluctuations in blood sugar levels.

5. Hydration: Staying hydrated is crucial. Water is the best choice, while sugary drinks should be avoided.

6. Physical Activity: Regular physical activity can improve insulin sensitivity and help manage blood sugar levels. Aim for at least 150 minutes of moderate aerobic activity each week, such as brisk walking.

In summary, your mother’s current blood sugar level suggests she is in the prediabetes range, and lifestyle changes are the first recommended approach. Medication may not be necessary at this stage, but it’s essential to monitor her blood sugar levels regularly and maintain open communication with her healthcare provider. If her condition changes or if she has any concerns, she should consult her doctor for further evaluation and guidance.
I hope this information helps clarify your questions and provides a good starting point for managing your mother’s health!
