I'm middle distance swimmer I like to do 800m and 1500m swims. I hadn't swam in ages and had to build myself up to those distances and I can do it consistently now BUT lately around the 250m mark I start to feel nauseous and disorientated and I have to stop, and I fell nauseous for about 2 hours after the swim.
The pool is an indoor heated pool, although it has happened in the outdoor non heated pool but not as bad.
I'm an blood pressure medication.
I don't know much about the sort of calories I should be having for this kind of swimming but I eat around the 1300.
Or do you think it may be serious????????
