Controlling low blood sugar -

They may not notice the warning signs, which may lead to severe and possibly fatal complications. People may experience hypoglycemia for reasons including :. The digestive system breaks down carbohydrates from food. Glucose enters the bloodstream after we eat.

Insulin, a hormone the pancreas produces, then allows cells in the body to absorb glucose. This means that even if plenty of glucose is available in the bloodstream, cells will starve of energy without insulin. After eating, the pancreas automatically releases the right amount of insulin to allow cells to absorb enough glucose from the bloodstream.

As glucose enters the cells, blood sugar levels fall. Any extra glucose goes into the liver and muscles in the form of glycogen, or stored glucose.

The body can use this glucose later when it needs more energy. If glucose levels fall because an individual has not eaten for a while, the pancreas secretes glucagon, another hormone, which triggers the breakdown of stored glycogen into glucose. If people take insulin and inject too much, it can cause cells to absorb excess glucose from the bloodstream, leading to low blood sugar.

Both type 1 and type 2 diabetes involve a problem with insulin. In both types of diabetes, the cells do not get enough energy from glucose. People with type 1 diabetes and some with type 2 diabetes need to take insulin or other medications to reduce their blood sugar levels.

A person does not need to increase their dose to have too much insulin in their body. It may be that the insulin they took was more than their body needed at that moment. According to the NIDDK , insulin and two other diabetes medications — sulfonylureas and meglitinides — can result in hypoglycemia.

Learn about insulin resistance here. Some children experience pediatric ketotic hypoglycemia, a condition involving low blood sugar levels and high levels of ketones. If people do not have enough glucose to use as energy, the body begins to break down fat in the body instead.

The body produces chemicals called ketones as a by-product of breaking down fat. According to a study , pediatric ketotic hypoglycemia usually occurs due to poor intake of food, a gastrointestinal illness and vomiting, or a period of prolonged fasting.

Severe metabolic and hormonal conditions may also cause pediatric ketotic hypoglycemia. Pediatric ketotic hypoglycemia may affect children from 6 months old and often resolves after the age of 6 years.

Symptoms of hypoglycemia in infants and children may include:. If a child shows any of the above signs or symptoms, a doctor should examine them as soon as possible. Symptoms tend to appear suddenly, according to the Genetic and Rare Diseases Information Center GARD.

The composition of the meal—how much fat, protein, and fiber are present—can also affect the absorption of carbohydrates. Physical activity Exercise has many benefits. Medical IDs Many people with diabetes, particularly those who use insulin, should have a medical ID with them at all times.
