Heat Exhaustion And CF

This past weekend, Azer's team had a tournament. On Saturday, they had two games. He pitched several innings. He felt alright at the end of the day, but hadn't drank enough fluids and felt very tired.

Sunday, they played one game. He had started his morning bolus a little later than usual because he slept a little later. By the time he needed to start warming up on the field, he said his stomach still felt full, and he sat in the dugout to avoid vomiting. He had pitched a little while, and drank mostly water in the dugout between innings.

That evening at home, he still hadn't drank much more. We started to run some Gatorade through his G-tube, and he vomited it all up. He said he felt very tired. He ate a small amount of food for dinner. In the middle of the night, he ended up vomiting up his night feed. He said he was still feeling physically exhausted.

After communicating with the CF clinic, we decided to skip a bolus feed, and run Gatorade through his G-tube throughout the day.

We have been in the ER before due to dehydration. Apparently, in Cystic Fibrosis you can have heat exhaustion caused by low sodium in the blood. So, by drinking water in addition to aggressively sweating in hot weather, the salt in the body is not being replaced and this can cause hyponatraemia, which is having a low sodium level in the blood.
