Type 1 – Symptoms

The main symptoms of diabetes (both type 1 and type 2) are:

  • feeling very thirsty (polydipsia)
  • urinating frequently (polyuria)
  • feeling tired
Other symptoms can include:

  • weight loss and loss of muscle bulk (in type 1 diabetes)
  • itchiness around the vagina or penis
  • regular bouts of thrush (a yeast infection)
  • blurred vision
  • cramp
  • skin infections
  • vomiting
Hypoglycaemia – or Hypo’s
Hypoglycaemia is a very low blood glucose. It usually occurs because someone has taken too much insulin but it can occur after vigorous exercise or drinking alcohol without having had anything to eat for some time. A hypo is very dangerous and requires immediate attention.

Symptoms of a “hypo” include:

  • feeling shaky and irritable
  • sweating
  • tingling lips
  • feeling weak
  • hunger
  • nausea (feeling sick)
  • confusion
  • slurred speech
  • unconsciousness
If you suspect you are having a hypo you should eat or drink something sugary immediately. This will normally improve things within a couple of minutes. If so, have a meal as the sugar you have just eaten will wear off. If the situation continues to worsen despite having something sugary to eat or drink do not hesitate to call 999.

This is when the blood glucose is too high and will occur if you are diabetic with poor glucose control or are unaware that you have diabetes. The symptoms of hyperglycaemia come on suddenly and severely. They include:

  • extreme thirst
  • a dry mouth
  • blurred vision
  • a need to pass urine frequently
  • vomiting
  • drowsiness leading to unconsciousness

Hyperglycaemia if uncorrected can be extremely dangerous. You should seek urgent medical attention if you have diabetes and you develop:

  • a loss of appetite
  • nausea or vomiting (feeling or being sick)
  • a high temperature
  • stomach pain
  • fruity smelling breath, which may smell like pear drops or nail varnish (others will usually be able to smell it but you will not)
