Glucagon initiates uptake of the stored glycogen in the liver into the bloodstream so as to increase glucose levels in the blood. Sporadic, high-carbohydrate snacks and meals are deemed the specific causes of sugar crashes. The “crash” one feels is due to the rapid increase and subsequent decline of blood sugar in the body system as one begins and ceases consumption of high-sugar foods. More insulin than is actually needed is produced in response to the large, rapid ingestion of sugary foods. Treatment
Reactive hypoglycemia can usually be relieved by dietary changes:
Avoiding or limiting sugar intake, including candy, sweet desserts, fruit juice, and drinks with added sugar. Eating only small amounts of starchy foods, including potatoes, pasta, breakfast cereals, and rice. Eating a variety of foods, including:
eggs, nuts, dairy products, tofu, beans, lentils, meat, poultry, fish, or other sources of protein with every meal or snack,
whole-grain carbohydrates, such as eating whole wheat bread instead of white bread, and
more fruits and vegetables (but not fruit juice), with 5 A Day being a recommended goal for most people. Eating more high-fiber foods, such as lentils, beans, pulses (legumes), leafy greens, and most fruits and vegetables.Other tips to prevent sugar crashes include:

Exercising regularly, as exercise increases cellular sugar uptake, which decreases excessive insulin release.
Above the hips, persons with spastic diplegia typically retain normal or near-normal muscle tone and range of motion, though some lesser spasticity may also affect the upper body, such as the trunk and arms, depending on the severity of the condition in the individual (the spasticity condition affecting the whole body equally, rather than just the legs, is spastic quadriplegia, a slightly different classification). In addition, because leg tightness often leads to instability in ambulation, extra muscle tension usually develops in the shoulders, chest, and arms due to compensatory stabilisation movements, regardless of the fact that the upper body itself is not directly affected by the condition. Social implications
Although the term "spastic" technically describes the attribute of spasticity in spastic cerebral palsy and was originally an acceptable and common term to use in both self-description and in description by others, it has since gained more notoriety as a pejorative, in particular when used in pop culture to insult non-disabled people when they seem overly anxious or unskilled in sports (see also the article Spastic (word)). In 1952, a UK charitable organization with a membership mainly of those with spastic CP was formed; this organization called itself The Spastics Society. However, the charity changed its name to Scope in 1994 due to the term spastics having become enough of a pejorative to warrant the name change.Spastic diplegias social implications tend to vary with the intensity of the condition in the individual.
