There are simple ways to reduce your risk of severe or prolonged hyperglycaemia:

• Be careful what you eat – be particularly aware of how snacking and eating sugary foods or carbohydrates can affect your blood sugar level.
• Stick to your treatment plan – remember to take your insulin or other diabetes medications as recommended by your care team.
• Be as active as possible – getting regular exercise can help stop your blood sugar level rising, but you should check with your doctor first if you're taking diabetes medication, as some medicines can lead to hypoglycaemia if you exercise too much.
• Take extra care when you're ill – your care team can provide you with some "sick day rules" that outline what you can do to keep your blood sugar level under control during an illness.
• Monitor your blood sugar level – your care team may suggest using a device to check your level at home so you can spot an increase early and take steps to stop it.
