What would happen to the blood glucose level if diabetic gave herself an injection but did not eat or accidentally too much insulin?

Answer 1

Excess insulin reduces the level of sugar in the bloodstream. Such can cause a person to feel weak, nausea, vomiting, tachycardia (rapid heart rate), dilated pupils, sweating, headache, ataxia (in-coordination), seizures and if severe enough it can even cause coma.

If have taken an insulin injection it is imperative that you eat something(unless you are something like 20 m/mol).

On a side note:

At one time insulin shock was used as a treatment for mental illness. Physicians would overdose a patient with insulin. The patient would pass out. Then the liver would gradually release sugar back into the bloodstream and the patient would recover.

Psychiatric Hospitals replaced Insulin Shock Therapy with Electroshock Therapy.

If you give yourself Insulin Shock Therapy, do not drive.

Answer 2

If a diabetic injects insulin but does not eat or accidentally takes too much insulin, their blood glucose level may drop too low (hypoglycemia). This can lead to symptoms such as shakiness, dizziness, confusion, and in severe cases, loss of consciousness. It is important for diabetics to monitor their blood glucose levels closely and seek medical help if they experience severe hypoglycemia.
