Seek immediate medical attention if you suspect an insulin overdose. Symptoms appear quickly and can be life-threatening.
Immediate Effects
An insulin overdose causes dangerously low blood sugar (hypoglycemia). Symptoms include shakiness, sweating, confusion, dizziness, and rapid heartbeat. Severe hypoglycemia can lead to seizures, coma, and death within hours. The speed of onset depends on factors like the amount of insulin taken, the individual’s metabolism, and recent food intake. Rapid treatment is vital.
Long-Term Effects
While immediate effects are the most pressing concern, repeated episodes of severe hypoglycemia can damage the brain and nervous system. This damage can manifest as cognitive impairment, including memory problems and difficulty concentrating. Long-term complications can also include nerve damage (neuropathy), leading to numbness and tingling in extremities. Consistent high blood glucose levels between episodes also increase risk of cardiovascular disease, kidney disease, and blindness.
Managing Insulin Safely
Accurate insulin dosing is paramount. Consult your doctor or diabetes educator regularly. Learn to recognize hypoglycemia symptoms and have a plan to treat them. Carry glucose tablets or a sugary drink to counteract low blood sugar quickly. Regular blood glucose monitoring provides critical feedback for adjusting insulin doses. Always follow your doctor’s instructions meticulously.
