Understanding the Causes and Symptoms of Hypoglycemia

Hypoglycemia is a term for low blood sugar. There are two main types of hypoglycemia. There is the reactive type that happens when a person eats a meal, and there’s the hypoglycemia that’s associated with diabetes. In both cases there is too much insulin in the blood, and this causes blood sugar levels to drop.

Information. Produced by cells in the islands of Langerhans in the pancreas, insulin is a hormone that regulates blood sugar or glucose. In reactive hypoglycemia, the pancreas may produce too much insulin in response to a meal, and the blood sugar crashes. A person with Type 1 diabetes needs to inject insulin, but if they inject it at the wrong time or inject too much, blood sugar levels can drop. This can also happen to people who take oral drugs to control their diabetes, but it is not as common.
