What should I do if I am unwell following surgery?

400 mls of milk or
200 ml carton fruit juice or
150-200 mls non-diet fizzy drink or
1 scoop of ice cream
- Drink at least 100 mls water / sugar-free fluid every hour, you must drink at least 2.5 litres (5 pints) per day
- Rest and avoid strenuous exercise
- If you carry out your own blood tests, these should be done every two hours day and night whilst feeling unwell
If you do not improve quickly and usually attend the hospital for diabetes care then telephone Diabetes Team on 01935 384 517 (Monday to Friday mornings).
Outside these hours, contact your GP practice or out of hours service. If you usually see your GP about your diabetes then phone your GP practice.
Treatment for Hypoglycaemia
(if blood sugar less than 6 mmol/litre)
- If you have any symptoms of low blood sugar such as sweating, dizziness, blurred vision or shaking please test your blood sugar
- If it is less than 6 mmol/l take 150 mls of a non-fizzy sugary drink or four glucose tablets
