Welcome to the forum. Ideally after a thorough stomach wash, side effects like nausea
, pain abdomen, dizziness
, etc can occur. Symptomatic treatment is done, you need not worry. She will be monitored 24-48 hours for any infection or side effect. If you see any reactions within this period you should report immediately to your treating doctor.
Intake of such a liquid, indicates that she is disturbed for some reason. If she remains fine, it is okay. Else, you should take the help of a counselor or a psychiatrist
. Do not leave her all alone for a month or so.
Give her family support, keep her well hydrated and give nutritious food so that she will be fine soon. Take care.
