What will happen if a diabetic injects and overdose of insulin?

An overdose of insulin can cause a diabetic to experience hypoglycemia, which is a condition of dangerously low blood sugar. Hypoglycemia can be extremely dangerous and, if left untreated, can even lead to death. Insulin is used to help control blood sugar levels in people with diabetes by allowing glucose, or sugar, to enter the body's cells where it can be used for energy. Too much insulin in a short amount of time causes blood sugar levels to drop quickly, which can result in various symptoms including: Shakiness, Weakness, Hunger, Headache, Confusion, Dizziness, Sweating, Nausea, Vomiting, Seizures, Unconsciousness. Insulin overdoses require immediate treatment with a sugary snack or drink, if the victim remains conscious. More severe cases may require medical attention, such as Glucagon injection or IV fluids. To avoid overdose situations, diabetics should carefully monitor their insulin dosage, blood sugar levels, and follow the advice of their healthcare provider.
