[SuziQ]

During a medical checkup her doctor told Marie that her potassium level was dangerously low and that she had to eat more. "But Marie paid no attention. She can't cope with negative comments about her weight. She decided she was going to lose weight as quickly as possible."

That may be one of the reasons she fainted after that segment of the competition.

[Jane Austen]

A woman I know fainted and the doctor said it might have been because she had not enough salt in her diet. I had never heard of this before.
