4 warning signs of low blood sugar that few people notice

Too low blood sugar, also known as hypoglycemia, also affects health.

1. Dizziness

When your blood sugar is low, your brain tries to conserve as much energy as possible. This can make you feel dizzy.

If you experience this common symptom of hypoglycemia, experts recommend adding 15 to 20 grams of fast-acting carbs, such as fruit juice.

In addition, if dizziness lasts more than 15 minutes, see a doctor for a check-up.

2. Feeling anxious

When your blood sugar drops too low, your body releases the hormones epinephrine (also known as adrenaline) and cortisol to signal your liver to release more sugar into your blood. This makes you feel jittery and anxious.

In addition, hypoglycemia can lead to shaking, sweating and rapid heartbeat. If this condition persists, it can affect your health, emotions and can worsen complications of diabetes (if any).

3. Sweating

Sweating is often one of the first signs of hypoglycemia. Like shaking, sweating is related to a surge of adrenaline and noradrenaline when glucose levels drop. According to research, up to 84% of people with diabetes experience sweating when they have hypoglycemia.

However, sweating will stop once the person takes in sugar.

4. Insomnia

Doctors use the term “nocturnal hypoglycemia” to refer to blood sugar levels that drop below 70 mg/dl at night. This can cause a number of sleep problems, such as sweating, nightmares, and insomnia.

According to Everyday Health, a bedtime snack can reduce the frequency and severity of sleep disturbances. Ideally, blood sugar levels should be between 90 and 150 mg/dL before bedtime, according to the Joslin Diabetes Center.
