What happens if a non diabetic person takes high dose of insulin?

When someone who is not diabetic takes a high dose of insulin, which is normally used as medication for people with diabetes, potentially significant issues can arise, including:

Low Blood Sugar (Hypoglycemia): Insulin's primary function is to lower blood sugar levels. In a non-diabetic individual who is insulin-sensitive, taking a high dose of insulin can cause a sudden and significant drop in blood glucose, leading to a condition known as hypoglycemia. Symptoms of hypoglycemia can include sweating, shaking, dizziness, confusion, and if left untreated, can lead to seizures and loss of consciousness.

Cellular Glucose Uptake: Since insulin facilitates glucose transport into cells, a high dose of insulin may lead to an excessive uptake of glucose by cells throughout the body, including those that don't typically rely much on glucose as an energy source. This can disrupt normal cellular function and metabolism.

Electrolyte Disturbances: Insulin administration, especially in high doses, can affect the balance of certain electrolytes in the body, including potassium and phosphate. This can cause potential complications if the electrolyte levels go too low or too high.

Weight Gain: Insulin promotes the storage of glucose in cells as glycogen and fat. A high dose of insulin may enhance this effect and lead to weight gain if the excess glucose cannot be utilized or burned through physical activity.

Increased Risk of Cardiovascular Events: Some studies have suggested that non-diabetic individuals who take high doses of insulin for extended periods may have an increased risk of developing cardiovascular problems such as coronary artery disease and heart attacks.

It is important to note that the effects of taking a high dose of insulin in a non-diabetic individual can vary depending on individual factors and specific circumstances. Seeking immediate medical attention is recommended if a non-diabetic person accidentally or intentionally takes a high dose of insulin to prevent potential complications and receive proper treatment if needed.
