Susan

Susan uses fast-acting insulin before meals, and long-acting insulin at 8pm.  She often goes swimming during the week which is usually around 9-10pm when the pool is quiet. She has her normal fast-acting insulin dose before her evening meal at 5pm. She has noticed that before her swim her glucose level is okay, but then when she finishes she is often higher. She sometimes takes extra insulin or a correction dose to bring it down as she doesn’t like to go to bed with a high level. Quite often she notices she goes low during the night.
