What should you know about nutrition for prediabetes?

Prediabetes means blood glucose is higher than the usual range but does not meet the criteria for type 2 diabetes. It may cause no symptoms, so food choices alone cannot confirm whether levels have changed. A pattern built around vegetables, pulses, whole grains, unsweetened foods and a source of protein can slow digestion and improve fullness. Obesity, medicines, sleep and family history may also influence risk.

Use regular meals that combine fibre-rich carbohydrate with protein and healthy fats. Choose water or unsweetened drinks more often, and compare labels for added sugar and fibre. Keep portions of sweets, refined grains and sweet drinks smaller without treating food as a moral issue. A nutrition counsellor can fit advice to local foods, work schedules and cultural meals. If weight management is relevant, gradual changes are easier to review than extreme restriction. Keep taking prescribed medicines and attend diabetes screening.

Contact a clinician if you develop excessive thirst, frequent urination, blurred vision, marked tiredness or an unexplained change in weight. Seek urgent care for vomiting, confusion, severe weakness or difficulty staying awake. Arrange follow-up even when you feel well, because prediabetes may have few noticeable symptoms.

Which test should monitor my blood glucose, and when should it be repeated? What meal pattern suits my medicines and routine? Should I see a dietitian? Would a weight-management programme be appropriate?
