I do not know why they would be a problem unless someone had a kidney or other problem that was affected by something such as salt.
I do know that dehydration can bring on a migraine and other headaches. So, I would think that if someone is dehydrated and excessively thirsty after intense vomiting or diarrhe that the salts would sometimes be beneficial.
I have found that drinking something immediately when I get the sensation that my head is foggy and a migraine might start actually can help lessen a migraine.
I am not a doctor, however. I would ask your physician, because he knows your health and lab results.
I should try that, after a long migraine I'm soooooo thirsty. If I have Gatorade or something similar It quenches that thirst more quickly from the electrolights (spelling?). However I usually don't and I'm in no mood to go shopping so I drink what seems like an ocean of water, juice, tea, ect. I can't imagine that long term use of a salt packet would be harmful, but I'm not a doctor.
it is a mixture of salts in powder form to be mix in water. it is most commonly used to replace body fluid for diarrhea patients.
I have never heard of those. What are they and how do they work? Where do you get them?
