In some cases where symptoms persist- there is dehydration or the blood glucose level cannot be kept above 4 mmol/l- hospital admission may be required. If things are improving but the blood glucose levels are tending to stay low- insulin doses should be reduced. Do not stop the insulin- but consider reducing insulin doses anywhere from 20 to 30 per cent or more. A reduced insulin dose may be required for a number of days as it takes some time for the bowel to recover. Insulin doses may be difficult to judge in this situation- and if in any doubt- contact your diabetes team for advice.
