Brief Answer:
SYMPTOMS unreliable

Detailed Answer:
There is no definitive symptom as such that can 100% diagnose hypoglycemia accurately. This is because symptoms can be vague and non-specific.
The only way to be certain is to check the blood level of glucose.

The symptoms of low blood sugar can be different from person to person, and can change over time. During the early stages of low blood sugar, a person can:

●Sweat or tremble

●Feel hungry

●Feel worried

People who have early symptoms should check their blood sugar level to see if it is low and needs to be treated. If low blood sugar levels are not treated, severe symptoms can occur. These can include:

●Trouble walking or feeling weak

●Trouble seeing clearly

●Being confused, or acting in a strange way

●Passing out or having a seizure

Some people do not get symptoms during the early stages of low blood sugar. Doctors call this "hypoglycemia unawareness." People with hypoglycemia unawareness are more likely to have severe symptoms, because they might not know that they have low blood sugar until they have severe symptoms. Hypoglycemia unawareness often occurs in people who:

●Have had type 1 diabetes for more than 5 to 10 years

●Use insulin to keep their blood sugar level under tight control

●Are tired

●Drink a lot of alcohol

●Take certain medicines for high blood pressure or diabetes
