What is low blood sugar?

Here are 10 fast facts about hypoglycemia (low blood sugar). A hypo, as episodes of low blood sugar are known, is when your blood sugar is lower than 3.9mmol/l. It can make you feel strange, and it means you need to eat or drink something sugary very quickly to bring your blood sugar up. If you don’t treat low blood sugar it can lead to a diabetes emergency. You need to know how to test your blood sugar properly in order to get an accurate reading.

What are the symptoms of low blood sugar?

Everyone is different, but here are some of the most common symptoms:

  • Feeling nervous
  • Sweating
  • Hunger
  • Trembling
  • Weakness
  • Heart beating very fast

As you can see from this post on Diabetic South Africans, everyone has different symptoms of low blood sugar.

Some other symptoms of low blood sugar include:

  • Can’t see properly
  • Can’t talk properly
  • Can’t think properly
  • Numb tongue
  • Dizzy
  • Hot and shivery

What to do to correct low blood sugar

It’s important to act fast to avoid a diabetes emergency. If your blood sugar is under 3.9mmol/l, eat a sugary snack.

  • A few sweets
  • 2 tablespoons of raisins
  • A tablespoon of honey
  • Half a cup of fruit juice
  • 5 Super C sweets

Wait for 10 minutes and test again. If your blood glucose readings are not above 5mmol/l then repeat and wait another 10 minutes until your blood sugar is over 5mmol/l. Here are some more tips on snacking to prevent low blood sugar.

If you have too many lows, it’s possible to develop hypoglycemic unawareness – where there are no signs of low blood sugar. If this happens, discuss your blood sugar control with your doctor. You may be running too low, and need to adjust your insulin with your doctor.

  1. […] Most people eat their last meal of the day around 8pm and then fast through the night and morning until 1pm. You could also make this 7pm to 12pm (noon), or even have dinner at 6pm and then eat again at 11am. To burn fat, some people choose to exercise around 11am or noon – but people with diabetes need to be on the alert for low blood sugar. […]
