Feeling Irritable
Symptoms of hypoglycemia can mirror certain mental issues such as irritability, anxiety, and worry according to the university of Michigan.
Feeling Shaky

In case of hypoglycemia, people sometimes can feel unsteady because the body releases adrenalin to remind you to refuel it. Feeling unsteady after a meal may imply experiencing idiopathic postprandial syndrome (IPS).
Affected Vision
When bl00d sugar levels decrease, people, especially those with diabetes, may deal with blurred vision, double vision, or “black” spots.
Slurry Speach
If glucose levels drop below 40 mg/dL, a person can suffer slurred speech, muscle twitching, difficulty walking steadily, and emotional changes.
Disturbed Sleep
Experiencing troubles falling asleep can be a symbol of insomnia, but also of hypoglycemia.
Lack of Focus

Struggling to focus or concentrate is caused by lack of energy that comes from glucose. This can be occured by skipping meals in both children and adults.
Feeling Weak
Low blood sugar levels can affect the nervous system, leading to dizziness, weakness, and lightheadedness. Also, people suffering from diabetes may also experience headaches if their blood sugar levels decrease.
Seizures and Coma
While common symptoms of hypoglycemia can be changed with regular healthy eating, some of the more serious problems are seizures, fainting, or even brain damage. As with extremely high blood sugar levels, people with diabetes can deal with diabetic coma from hypoglycemia.
Heart Palpitations
Rapid heartbeat, heart palpitations, and fluttering can be a symbol of hypoglycemia.
