Sam – how to solve problems
Sam’s problems are that when he finishes his run his blood glucose is always higher than when he first gets up. He then takes his normal (and sometimes extra if he is very high) fast-acting insulin with breakfast. He has noticed he is often low at lunchtime. What he could try:
1. Before – He could have a very small carb snack with 35-50% of the normal fast-acting insulin dose (This will give him insulin in his body to stop him from going high during exercise from his liver glucose).
2. After – He could take a reduction of his normal breakfast dose of 35-70% (This would give him less insulin working as he is at risk of delayed hypos after exercise). Or he could eat an extra 20-40g carbs with no extra insulin (To prevent hypos).
