Insulin spikes refer to sudden and significant increases in blood sugar levels, often caused by consuming food or drink that is high in carbohydrates. When this happens, the pancreas releases insulin, a hormone responsible for regulating blood sugar levels, to help transport glucose from the bloodstream into cells where it can be used as energy. Insulin spikes occur when there is an excessive amount of insulin released in response to the sudden influx of glucose, leading to rapid and dramatic drops in blood sugar levels. This can cause a range of symptoms such as dizziness, confusion, irritability or even loss of consciousness if not addressed promptly by consuming food or drink that helps to stabilize blood sugar levels.
