Are night sweats a sign of low blood sugar in diabetes?

Question

Hello doctor,

I am reaching out with concerns about my uncle’s health. He’s 52 years old and has had type 1 diabetes for many years. He is currently using Lispro insulin injections. His blood sugar levels have fluctuated lately, and we have noticed some troubling symptoms, particularly at night. He often experiences excessive sweating and dizziness, which makes me wonder if he might be having episodes of low blood sugar. Could these symptoms be signs of nocturnal hypoglycemia?

Do you think this may require changes to his treatment plan or additional tests? Also, if there are any updated guidelines or strategies for better managing diabetes, especially in situations like this, I would be very grateful for your advice.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern.

Your uncle’s symptoms, such as nighttime sweating and dizziness, may be caused by low blood sugar levels (hypoglycemia). To help manage this, I suggest reducing his insulin dose by 2 units. It’s also important to increase the frequency of blood sugar checks, especially before bedtime and during the night, to catch any sudden drops in glucose levels.

Encourage a balanced diet with consistent carbohydrate intake, as this can help keep his blood sugar more stable throughout the day and night. In addition, regular, moderate exercise can be beneficial. It helps improve insulin sensitivity, which means the body responds more effectively to insulin, but the timing and intensity should be adjusted to avoid hypoglycemic episodes.

He may benefit from using a continuous glucose monitor (CGM), which provides real-time tracking of glucose levels and can help detect sudden drops, especially overnight. Additionally, an HbA1c (A1c) test can be useful to assess his average blood sugar control over the past two to three months.

For more specific recommendations, please share the following details:

His recent blood sugar readings.
Insulin dosage and timing.
An overview of his daily diet.

I hope that you get your answer.

Please, let me know if you want some help.

Thank you.
