You said hypo that means someone has low blood glucose levels so I'm a bit confused.
Where does your mother live? I ask because there are different units used for glucose measurements in different parts of the world.
If she is in the UK (and some other places) a level of 14 would mean her blood glucose was fairly high , eating would not bring her level down . It would rise
In this case then pump994s advice is good advice.
If she is in the US (and again some other places) a level of 14 would be very, very low and you were right to tell her to eat something but it would be important to get someone to check on her
