Diabetes often presents subtle nighttime symptoms that shouldn’t be ignored. One common sign is frequent urination, caused by excess glucose forcing the kidneys to work harder, leading to disrupted sleep. Night sweats and hypoglycemia—marked by trembling, hunger, confusion, or heart palpitations—may also occur due to low nighttime blood sugar.

Other signs include restless legs syndrome, linked to nerve damage from high glucose levels, and sleep apnea, often tied to obesity and insulin resistance. Increased thirst and dry mouth are common as the body loses fluids through frequent urination. Persistent fatigue, despite adequate rest, and sleep disorders such as insomnia are also red flags.

Additional overlooked symptoms of prediabetes or diabetes include dark patches of skin (acanthosis nigricans), unexplained weight loss, blurred vision, small yellowish skin bumps, skin tags, slow-healing wounds, and itchy or tingling skin—all of which suggest poor blood sugar regulation.
