I have been facing Exercise-induced vomiting since I have resumed my exercise sessions recently. I tried to search for it today and see what could be the possible cause and solutions for this problem. I found two very useful sources of information. Below is an exert of two sources:
Well it could be to do with your dietry intake prior to exercise, ideally eat 1 1/2 hour prior to exercise, then consume simple based water drinks during training, preferably water as this is the simplest form of fluid intake, low concentration in complex vitamins, thus less to breakdown once drank.
Another cause, and my personal opinion as to what is happening, means heat exhaustion and fatigue due to the high intensity exercise. This is a natural occurrence of the body and here’s why.
When exercising, the brain diverts all energy to the areas in use, e.g. biceps in a bicep curl, legs and lungs when running. If there is food currently being digested when exercise is initiated, the body will pause this process, and begin to divert energy to the area of the body being worked.
This however means your food is partially digested, and needs to go some where. Upon finishing exercise, the digestive transit can resume, however with no energy (which occurs after High Intensity Exercise), the food cannot continue, so basically, needs to reverse back to stop the process, Result=Vomiting.To overcome this, simple consume a high energy sauce upon finishing exercise, my personal favourite and necessity in the gym has to be bananas, High Potassium content, high energy content, highly recommended.
