Does having to much insulin cause nausea?

Yes, having too much insulin can cause nausea.

Insulin is a hormone that helps the body use glucose (sugar) for energy. When insulin levels are too high, it can cause a condition called hypoglycemia (low blood sugar). Symptoms of hypoglycemia can include nausea, vomiting, sweating, shaking, and dizziness.

In some cases, severe hypoglycemia can also cause seizures, loss of consciousness, and even death. Therefore, it is important to keep insulin levels in a healthy range. If you are experiencing symptoms of hypoglycemia, it is important to eat or drink something sugary to raise your blood sugar levels. If your symptoms are severe, you should seek medical attention immediately.
