What to Expect at the Emergency Room
Take the medicine container to hospital with you, if possible.
The health care provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure.
Tests that may be done include:
- Blood and urine tests
- Chest x-ray
- ECG (electrocardiogram, or heart tracing)
Treatment may include:
- Intravenous fluids (given through a vein)
- Medicine to treat symptoms
- Activated charcoal
- Breathing support, including a tube through the mouth into the lungs and breathing machine (ventilator)
Some of oral hypoglycemics may stay in the body for a long time, so the person may need to stay in the hospital for 1 to 2 days. Permanent brain damage and death are possible, especially if blood glucose level does not return to normal in a timely manner. Infants, children, and older people are most likely to develop more serious and long-term complications from low blood sugar levels that are not corrected rapidly.
