This habit can raise blood sugar and put them at risk of obesity and diabetes.In 2005, a study of over 1400 participants showed that participants who habitually slept few hours were more likely to have associations with type 2 diabetes. However, because this study was merely correlational, the direction of cause and effect between little sleep and diabetes is uncertain. The authors point to an earlier study which showed that experimental rather than habitual restriction of sleep resulted in impaired glucose tolerance (IGT). Other effects
The National Sleep Foundation identifies several warning signs that a driver is dangerously fatigued. These include rolling down the window, turning up the radio, trouble keeping eyes open, head-nodding, drifting out of their lane, and daydreaming. At particular risk are lone drivers between midnight and 6:00 am.Sleep deprivation can negatively impact overall performance, and has led to major fatal accidents. Due largely to the February 2009 crash of Colgan Air Flight 3407, which killed 50 people and was partially attributed to pilot fatigue, the FAA reviewed its procedures to ensure that pilots are sufficiently rested. Air traffic controllers were under scrutiny when in 2010 there were 10 incidents of controllers falling asleep while on shift. The common practice of turn-around shifts caused sleep deprivation and was a contributing factor to all air traffic control incidents. The FAA reviewed its practices of shift changes and the findings saw that controllers were not well rested.
Gastric distention is the enlargement of the stomach, and can be due to a number of causes.Physiologic (normal) gastric distension occurs when eating. Distension of the upper stomach stimulates the secretion of stomach acid, while distension of the lower stomach stimulates gastrin secretion. Distension of the stomach also stimulates the secretion of ghrelin.Other causes include:

binge eating associated with bulimia nervosa
tumors causing obstruction
diabetic neuropathy
scarring due to pyloric gastritis
delayed gastric emptyingTo identify the cause of gastric distention, an upper endoscopy or barium upper GI imaging should be done. == References ==
