7 Nighttime Warning Signs of High Blood Sugar

Introduction

High blood sugar, or hyperglycemia, can silently affect your health, especially while you sleep. Often, people aren’t aware their glucose levels are elevated until symptoms appear. Recognizing these nighttime signs can help you take action early and prevent complications.

1. Frequent Urination at Night (Nocturia)

When blood sugar levels are high, your kidneys work harder to filter and absorb excess glucose. This can lead to increased urine production, causing multiple trips to the bathroom at night.

2. Excessive Thirst

High glucose levels can dehydrate your body. If you wake up thirsty repeatedly during the night, it may indicate your blood sugar is elevated.

3. Night Sweats
