Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.
Get emergency help if someone cannot be woken, has a seizure, faints, has severe confusion, chokes, or is seriously injured.
If low blood sugar is suspected and the person cannot safely swallow, do not give food or drink by mouth.
Seek same-day medical advice if nighttime eating is accompanied by shaking, sweating, a racing heartbeat, confusion, or an unusually low glucose reading, especially if you take diabetes medicine.
Follow your established low-blood-sugar plan while arranging help.
Unaware cooking, leaving appliances on, or eating toxic or inedible substances also needs prompt medical assessment because it creates an immediate safety risk.
Book a routine appointment if night eating happens about weekly for several weeks, causes distress, interrupts sleep, or feels difficult to control.
Also arrange an appointment if you have memory gaps, unexplained weight change, frequent binge-like episodes, or concerns about your relationship with food.
Every sign above is quoted from the sofidex article on Night eating. If you are not sure, err upward — it is always reasonable to be checked.
