Death
It depends how much mercury you swallow and whether and how soon you get medical treatment. It is vary rare to die from swallowing mercury as it is not readily absorbed through the gastrointestinal tract.
If you swallow mercury, very little is absorbed. Most of the mercury is eliminated through the digestive tract.
