I’ve been feeling a little weak lately, and yesterday while tanning in the sun, i got up for a drink of water and fainted.

my friend B said it was probably low sugar
my friend G said it was probably low blood pressure

B told me to drink some coke
G told me to have a bit of salt

I ended up doing both since i had no idea what to do.
Im going to the doctor next week, but would grateful if someone could give me an insight of what might be wrong.

thanks!

Low blood pressure is when the amount of blood your heart pumps is too low. Low blood sugar is when the amount of sugar in your blood is too low. If you hadn’t eaten in awhile it could be low blood sugar, but you may have been dehydrated from laying out in the sun too.
