16 Sneaky Symptoms That Could Mean Your Blood Sugar Is Too High

15. Dry, Itchy Skin

Dry, itchy skin is a common symptom of diabetes and often arises due to high blood sugar levels. Elevated glucose levels can cause frequent urination, leading to dehydration as the body draws fluid from tissues, including the skin, to help flush out excess sugar. This lack of moisture can leave the skin feeling rough, dry, and prone to itching. Poor circulation, a common complication of diabetes, can further impair the skin’s ability to retain hydration, exacerbating dryness and increasing susceptibility to cracking or infections. The issue is often most noticeable on the arms, legs, and elbows, areas more exposed to friction and environmental factors. Regular use of fragrance-free moisturizers, staying adequately hydrated, and avoiding long, hot showers can help alleviate these symptoms. However, persistent dryness and itchiness may indicate underlying complications, such as diabetic dermopathy or infections, requiring medical attention. Proper blood sugar management remains the cornerstone of preventing and addressing these skin-related issues.

16. Sleep Problems

Diabetes frequently disrupts sleep, making restful nights elusive for many patients. High blood sugar levels can cause frequent urination at night, known as nocturia, which interrupts sleep cycles and leaves individuals feeling fatigued the next day. Conversely, low blood sugar during sleep can trigger night sweats, palpitations, and feelings of shakiness or anxiety, causing individuals to wake suddenly. Over time, these fluctuations in blood sugar can lead to chronic sleep deprivation and affect overall well-being. Additionally, people with diabetes are at a higher risk of developing obstructive sleep apnea, a condition characterized by repeated interruptions in breathing during sleep. Sleep apnea exacerbates fatigue and increases the risk of cardiovascular complications, further complicating diabetes management. Addressing sleep problems involves stabilizing blood sugar levels before bedtime, creating a consistent sleep schedule, and ensuring a comfortable, dark, and quiet sleeping environment. For those with sleep apnea, treatments like continuous positive airway pressure (CPAP) therapy can help improve breathing and overall restfulness, leading to better blood sugar control and overall health.
