Commonly defined as a blood glucose (BG) level below 4.0mmols. Keeping your BG levels above 5mmols is a safer level to be.
You may feel symptoms at a higher level than this if your BG levels have been high for a while and come down quickly.
Any person with diabetes treated with insulin or Sulphonylureas (Diamicron, Amaryl) that increase insulin production, are at risk of having a hypo.
What may cause a hypo?
- Missed or late meal
- Insufficient carbohydrate with meal or snack
- Increase in physical activity – you need to reduce insulin before this. If on oral medication, discuss with your GP.
- Sickness with vomiting
- Consuming alcohol on an empty stomach or drinking too much.
- Accidently taking your insulin twice
NB. You may not experience symptoms of hypo if:
- You’ve had diabetes for many years (as a result of internal nerve damage)
- You’ve been having frequent hypos
- You’re on a medication for blood pressure known as beta blockers.
You’ll only be able to detect a hypo by checking your BG level regularly or wearing a continuous monitoring device. If you are in this group, it’s important to see a Diabetes Educator who’ll help you create a plan to keep you safe and explain simpler ways you may be able to check and manage your BG.
Treating a Hypo
Step 2: Wait 15mins and recheck BG level. If above 5mmols go to Step 3. If not, repeat Step 1.
Step 3: Maintain your BG levels with SLOW acting carbohydrate. This could be your meal (which includes carbohydrate) if it’s due now, or try one of these:
- 1 piece of fruit – apple, pear, peach,
- Dried fruit – handful of sultanas, 3-4 dried apricots
- Muesli bar
- 1 slice of multigrain bread
- Glass of milk or tub of yoghurt
- Eat regular meals, with enough carbohydrate at each meal.
- Ensure correct medication dose is taken
- Know/learn how to adjust your insulin if you’re having less carbohydrate, are more physically active or have lost weight.
- Ensure your BG is above 5mmols when you exercise. If not, have a carbohydrate snack (as listed in Step 3). Speak with your GP or Diabetes Educator about adjusting your medication these days vs extra snacking.
- Avoid alcohol on an empty stomach
- Keep fast acting carb in zip locked bags everywhere: car, handbag, work, etc.
You must be above 5mmols to drive. If not, you put at risk:
- Yourself and those in your car
- Other drivers or pedestrians
- Your insurance policy to cover you
- Your license being suspended
- Pull over as soon as you have hypo symptoms
- Remove the keys from the ignition
- Treat your hypo
- You are not to drive until 30 minutes after your BG level is above 5mmols
Always follow up with SLOW acting carb.
