What are the symptoms of prediabetes?

Prediabetes means blood glucose is above the usual range but not in the diabetes range. Many people feel well because the change develops gradually. Excessive thirst and frequent urination are more commonly associated with higher glucose levels, including type 2 diabetes, rather than being dependable signs of prediabetes. Weight changes, tiredness or blurred vision can have many causes and cannot confirm the condition from symptoms alone.

If you have risk factors or a clinician has suggested checking your glucose, arrange diabetes screening even if you feel well. The assessment may include a blood test and a discussion of your medical history. Nutrition counselling and a weight management programme can help you choose practical changes to meals, activity and routines. Do not stop prescribed medicines without advice.

Contact a clinician soon about ongoing excessive thirst, frequent urination, unexplained weight loss or marked tiredness. Seek urgent help for vomiting, severe weakness, confusion, or difficulty breathing, particularly if diabetes has been diagnosed or is suspected.

Ask which diabetes screening test is appropriate, when results should be reviewed, what your personal risk factors are, and which lifestyle changes would fit your health and daily routine.
