Raised glucose often causes no noticeable symptoms. Prediabetes means glucose metabolism is already impaired, but measurements do not yet meet diabetes criteria. This is an important time when targeted changes can bring substantial benefits.
Who is at higher risk?
Risk factors include excess weight, particularly a larger waist circumference, inactivity, diabetes in a close relative, high blood pressure, lipid disorders, previous gestational diabetes and polycystic ovary syndrome. Risk rises with age, but metabolic problems also occur in younger people. NIDDK: insulin resistance and prediabetes.
How is prediabetes diagnosed?
A doctor may use fasting glucose, glycated haemoglobin HbA1c or a glucose tolerance test. Interpretation depends on the method and clinical situation. Acute illness, medication and some blood disorders can affect results, so a diagnosis is not based on a random home measurement alone. NIDDK: insulin resistance and prediabetes.
Which changes are most effective?
The goal is sustainable habits, not a short, strict diet. Regular aerobic activity and strength training, fibre-rich food, fewer sugary drinks and highly processed foods, adequate sleep and gradual weight loss where needed can help. Even moderate changes may improve insulin sensitivity. NIDDK: reducing the risk of type 2 diabetes.
Why assess more than blood sugar?
Prediabetes is often part of a broader risk pattern involving blood pressure, lipids, fatty liver and sleep apnoea. Good care therefore goes beyond one test. Doctor and patient agree priorities, repeat testing times and whether medication is needed. NIDDK: insulin resistance and prediabetes.
A consultation at KIRSH
Book an endocrinology consultation at KIRSH to assess glucose results and your individual metabolic risk. A nutrition specialist can support sustainable daily changes. Bring your test results and medication list.
