There is a direct relationship between serotonin and blood sugar. Insulin is a hormone that regulates blood sugar or glucose levels and helps cells in the blood use it for energy. In healthy people, insulin is produced by the pancreas, and the higher the level of blood sugar, the more it is released. When blood sugar levels are low in the bloodstream, less insulin is released. This system failure occurs in diabetics, where not controlling blood sugar levels can be potentially dangerous.
The relationship involves insulin, which is responsible for keeping blood sugar levels healthy. When we eat, food is converted into glucose through the digestive system and released into the bloodstream. The blood sugar is then absorbed into the body by the cells and used as energy. The hormone insulin is needed for blood sugar to enter the cells.
Foods high in sugar or carbohydrates are more likely to turn into blood sugar, but this can lead to blood sugar levels exceeding normal. When this happens, the pancreas releases more insulin. The extra insulin allows the cells to quickly absorb excess sugar from the blood. This allows blood sugar to quickly return to normal levels, because prolonged high blood sugar levels are very unhealthy.
If you don't eat for a few hours, your blood sugar levels drop below normal. The occurrence of this condition is also closely related to the relationship between insulin and blood sugar. The pancreas slows down the rate at which insulin is secreted, helping the rest of the blood sugar enter the cells more slowly and using stored glucose for energy.
Problems with the relationship between insulin and blood sugar are sometimes called diabetes. People with the disease lack adequate insulin to respond to elevated blood sugar levels.
