A member asked:

Can drinking a bottle of coke after doing a long walk in high heat/humidity cause lightheadedness?

A doctor has provided 1 answer

Probably: A long walk in the heat can can make you dehydrated . The sdden increase in sugar and caffeine from a coke can also make you feel light headed or dizzy . Medications could also cause these feelings . Please contact your primary provider to evaluate this further if it dosen't resolve soon
