Treatment for insulin shock

Insulin shock happens anytime when there is an imbalance between the insulin in the system, the amount food being eaten and the level of physical activities.

A person with high risk of insulin shock is a diabetic. Those who are diagnosed with diabetes who are dependent on insulin take injection during the day to manage the poor secretion of insulin by the pancreas. Sometimes, the body is given too excess insulin after an injection and result to insulin shock. This can occur within 15 minutes after using rapid-short acting insulin and several hours if taking a long-acting type of insulin.

  • If glucose tablets are available, give the affected person at least 3 glucose tablets.
  • Wait for 5 minutes if the symptoms are improving. If the symptoms decrease, give the person sandwiches, banana or a cookie that takes a longer time to digest to prevent energy crash that can happen after eating plenty of sugar.
