Management of Hypoglycemia

Hello, Doctor! I have experienced symptoms of hypoglycemia since elementary school, occurring about ten times a year.
After entering high school, these episodes have become more frequent.
My records show that I average a blood sugar test in the school health room every two weeks, with a fasting period of ten hours, resulting in a level of 80 mg/dL, which is within the normal range.
The nurse has determined that I am simply prone to feeling hungry, but recently the frequency has increased, typically occurring around 11 PM to midnight, about twice a week.
I eat three meals a day, with a moderate portion size, but I usually have dinner at 6 PM.
Should I undergo further metabolic testing, or would it be sufficient to eat smaller, more frequent meals? Thank you very much for your response!

Dear Ms.
Olivia:
1.
There are many causes of hypoglycemia, the most common being medications used by patients with diabetes.
Other causes include renal failure, certain tumors, liver disease, hypothyroidism, muscle starvation, congenital metabolic disorders, adrenal insufficiency, insufficient glucagon, adrenal insufficiency, severe infections, reactive hypoglycemia, excessive alcohol consumption, certain medications, severe illnesses, and more.

2.
What the school nurse mentioned is indeed possible.
However, since your condition has changed and worsened, it is advisable for you to discuss this further with your primary care physician or seek treatment at a metabolic clinic.

More Info

Managing hypoglycemia, especially when it becomes frequent, is an important health concern that requires careful evaluation and management. Based on your description, it sounds like you have been experiencing episodes of low blood sugar (hypoglycemia) for quite some time, particularly after dinner. Given that your blood sugar readings have been around 80 mg/dL after fasting for ten hours, this is indeed within the normal range, but the frequency of your symptoms is concerning.

Understanding Hypoglycemia
Hypoglycemia occurs when blood sugar levels drop below normal, typically defined as less than 70 mg/dL. Symptoms can include shakiness, sweating, confusion, irritability, and in severe cases, loss of consciousness. It is crucial to identify the underlying cause of your hypoglycemic episodes, especially since they are becoming more frequent.

Dietary Considerations
You mentioned that you typically eat three meals a day and have dinner around 6 PM. If you are experiencing hypoglycemia late at night, it may be beneficial to consider the timing and composition of your meals. Here are some dietary strategies that could help:
1. Frequent, Smaller Meals: Instead of three larger meals, try eating smaller meals or snacks every 3-4 hours. This can help maintain stable blood sugar levels throughout the day and prevent dips in the evening.

2. Balanced Meals: Ensure that your meals contain a good balance of carbohydrates, proteins, and healthy fats. Carbohydrates can raise blood sugar levels, but pairing them with protein and fat can slow down the absorption of sugar into the bloodstream, providing a more stable energy release.

3. Evening Snack: Since your symptoms occur late at night, consider having a small, healthy snack before bed. This could be something like a piece of fruit with nut butter, yogurt, or a handful of nuts. This can help maintain your blood sugar levels during the night.

When to Seek Further Testing
While dietary changes can be effective, it is also important to investigate the underlying causes of your hypoglycemia, especially since the frequency of your episodes has increased. Here are some indications that further testing may be necessary:
- Increased Frequency: If your episodes of hypoglycemia continue to increase in frequency or severity, it is essential to consult a healthcare professional.

- Severe Symptoms: If you experience severe symptoms, such as confusion, loss of consciousness, or seizures, seek immediate medical attention.

- Lack of Response to Dietary Changes: If adjusting your diet does not alleviate your symptoms, further testing may be warranted.

Recommended Tests
If you decide to seek further evaluation, your healthcare provider may recommend the following tests:
1. Glucose Tolerance Test: This test measures how your body responds to sugar and can help identify issues with insulin regulation.

2. Insulin Levels: Measuring insulin levels during episodes of hypoglycemia can help determine if your body is producing too much insulin.

3. C-Peptide Test: This test can help assess how much insulin your pancreas is producing.

Conclusion
In summary, while dietary changes such as eating smaller, more frequent meals may help manage your hypoglycemia, it is crucial to monitor your symptoms closely. If your episodes continue to increase in frequency or severity, or if dietary adjustments do not help, it is advisable to seek further testing to rule out any underlying metabolic disorders. Consulting with a healthcare professional, such as an endocrinologist or a registered dietitian, can provide you with tailored advice and management strategies to help you maintain stable blood sugar levels and improve your overall health.
