Thank you for posting your query.
Your sister is most likely suffering from catamenial epilepsy- where the person has fits
only during menstrual periods. The underlying cause is supposed to be linked to hormonal
In this condition, anti-epileptic medications are required to prevent the recurrence of seizures. Most doctors would advise the use of medications during the periods (to start a few days before period starts and stop it after the bleeding stops)- about 10 days per month.
The pain in the liver
area is not due to epilepsy, it needs evaluation by a doctor.
