Hi, Welcome to Health care magic forum .
The
fits may be due to the
epilepsy,
hypertension, or larva of the intestinal worms in the brain, or
tuberculosis.
If it is confirmed epilepsy, the liquid from the mouth might be the blood, from the stomach, and will be dark brown in color, or may be the blood from the intestine, which will be dark brown in color.
The source of blood may be the oozing from the stomach, intestine, or due to the biting of the tongue, during the fit.
If there is concomitant hypertension, may be the bleeding into gi tract, due to the hypertension.
Any how you should be relaxed ,about the matter, to prevent you becoming nervous .
Wishing for a quick and complete recovery. Thank you.
