I know that a lot of people get their thyroid tested, but has anyone gotten tested for vitamins that are lost through sweat like magnesium, potassium, iodine, etc.? I know that taking extra vitamins might not solve the hyperhidrosis, but it might help your health overall. Even though I can't stand the sweating, sometimes I also worry about what some of the other side effects it is having on my health such as vitamin and mineral deficiencies.
