A large international study published in Occupational and Environmental Medicine, has indicated that people doing shift work were at highest risk of contracting Type 2 diabetes .
The main cause is thought to be the disruption to the body clock which often occurs with rotating shift patterns. This can affect waistlines, hormones and sleep which could increase the risk. Another idea is that eating late at night makes the body more prone to store the energy as fat, increasing the risk of obesity and in turn type 2 diabetes.
Type 2 diabetes can lead to blindness, increase the risk of heart attacks and strokes, as well as damaging nerves and blood vessels – dramatically increasing the risk of a foot needing to be amputated.
