How are dizziness, hypoglycemia, and low calcium related in diabetes?
Dizziness is a common symptom of hypoglycemia (low blood sugar) in people with diabetes. When blood sugar drops below 70 mg/dL, the brain receives less glucose, which can cause several symptoms:
* Dizziness or lightheadedness
* Shakiness or feeling anxious
* Sweating or chills
* Confusion
* Weakness
Dizziness can occur in different situations for people with diabetes. It may happen after eating due to reactive hypoglycemia, especially if insulin or diabetes medications cause blood sugar to drop too much following a meal.
Another diabetes-related cause is postprandial hypotension (low blood pressure after eating). When you digest food, blood flows to your digestive system. If your heart rate doesn't compensate adequately, your brain gets less blood, causing dizziness. People with diabetes are at higher risk for this condition.
Inner ear dysfunction is also more common in people with diabetes and can contribute to dizziness and balance problems, whether related to meals or not.
If you're experiencing frequent dizziness, track when it happens and check your blood sugar levels. Severe hypoglycemia can be dangerous and may even cause seizures if untreated, so contact your doctor to discuss adjusting your medications or management plan.
