  • Palpitations and a fast pulse
  • Lips feeling tingly
  • Blurred sight

You shouldn’t be having a lot of hypos and they shouldn’t be severe. If they are, get in touch with your healthcare team.
It can be a good idea to record your hypos, to see if there are any trends or patterns. Knowing this may help your healthcare team find the best diabetes treatment for you.6
