Detailed Answer:
Hi and thanks for your query.

If doctor have excluded that fainting is not a sign of anemia,hypoglicemia and hypotension,please ask IF sister remembers whether her conscience was saved when dropped.
If her conscience was saved ,don't worry.

Fainting with saved conscience have other many causes after we excluded the above causes .
These cause are:
inner ear
cold and flu
panic disorder
benign positional vertigo
If repeated ,she should go to check her inner ear and exclude panic disorder.

All the best
