Riding The Blood Sugar Rollercoaster

The blood sugar rollercoaster, also known as ‘dysglycemia’ is when sugar levels quickly bounce between highs and lows (see graph below). The rollercoaster causes severe fatigue as well as detrimental physical and mental symptoms.

Many factors can cause the rollercoaster, such as:

  • Severe hypoglycaemia
  • ‘Rage bolusing’
  • Eating too much or too little
  • Menstrual cycle
  • Intense exercise
  • Illness
  • Lack of sleep

My Tips On Handling The Blood Sugar Rollercoaster

1.Portion your hypo snacks before When you have hypoglycaemia it can send you into a ‘hangry’ monster, trying to eat everything in sight. To prevent this I always carry/have portioned hypo snacks, for example I have small juice bottles and small boxes of raisins etc. This can help to prevent over-treating a low sugar, causing a rebound high.

2. Resist the ‘rage bolus’ If you do become a hangry monster (don’t panic we have all been there!) try not to take a big dose of insulin to overcome the high sugar. I know it’s annoying, but bringing sugar levels back down gradually is preferable because it will prevent another sudden hypo.

3. Close your eyes and rest – If your sugar levels are everywhere it can become tiring and stressful. When we get stressed it can cause blood sugar levels to rise even more, which is not ideal in this situation. So I like to close my eyes and focus on my breathing, always set a 20/30 minute alarm incase you fall asleep so you can check your levels again.

4. Reach out to your support network – If you are feeling really unwell and are struggling, ask for help! If you need someone to grab you snacks or give you a hug, ask your parents, partner, friends, whoever is your go-to!
