Waking up with high blood sugar can be a sign of hyperglycemia. Here are the most common symptoms and normal blood sugar levels.
Waking up with high blood sugar is a common problem in people with diabetes and may be related to morning hyperglycemia.
According to the Mayo Clinic, one of the first effects of this condition is that excess glucose passes into the urine, causing fluid loss and dehydration.
Health Site experts point out that there are specific signs that help identify an increase in glucose at the beginning of the day.
Among the most frequent symptoms are:
- Blurred vision: High glucose affects vision, making it difficult to see clearly upon waking.
- Intense thirst: A constant feeling of thirst may indicate that the body is trying to compensate for water loss.
- Frequent urination: Your kidneys work to eliminate excess sugar, causing you to need to go to the bathroom repeatedly, even early in the day.
- Fatigue and weakness: Although glucose is the main source of energy, the body with hyperglycemia does not process it properly, causing fatigue upon waking.
- Concentration problems: High blood sugar levels can interfere with cognitive performance, making it difficult to pay attention and remember.
In addition to these signs, other symptoms such as headaches, tingling in the extremities, dark spots on the skin, or recurring infections may also indicate high blood glucose .
Normal glucose levels and risks of sustained hyperglycemia
According to Medline Plus, adults should maintain glucose levels between 90 and 130 mg/dL before meals and not exceed 180 mg/dL after meals. However, if levels consistently remain between 120 and 160 mg/dL, it is advisable to see a doctor, as prolonged hyperglycemia can cause serious organ and tissue complications.
Diabetes control and blood sugar regulation are essential to prevent complications. In some cases, adjusting medication, modifying insulin doses, or reviewing diet before bed can help maintain better glucose balance upon waking.
