10 Symptoms of Hypoglycemia
Symptom #10: Faster Heartbeat
Having low blood sugar can cause the heart to beat faster than normal. This happens because when the brain senses that the body cannot get adequate energy to perform its functions properly, it signals the adrenal glands to increase production of adrenaline. The adrenaline hormone causes the liver to increase production of glucose from stored glycogen.
Adrenaline is also the fight or flight hormone that prepares the body to deal with emergencies. As a consequence of the increased adrenaline, the heart beats faster than normal in order to supply more blood to deliver glucose and oxygen throughout the body. Heart palpitations are additional hypoglycemia symptoms that may affect the heart.
