High blood sugar and cholesterol

Blood sugar may be high temporarily after eating, during illness or with certain medicines, while cholesterol is interpreted through its different components and your overall health. Results may prompt repeat testing or an assessment for diabetes and other metabolic conditions. Neither result alone explains every symptom, and many people notice no symptoms.

Over time, excess glucose and cholesterol-related changes can affect artery walls. This can contribute to problems such as [Peripheral Arterial Disease](/conditions/peripheral-arterial-disease/) or [Stroke](/conditions/stroke/), but a result does not mean one of these conditions is present. Your clinician considers blood pressure, family history, smoking, kidney health and other factors.

Book an appointment to review whether each test was fasting, whether repeat testing is needed and whether medicines or illness could have influenced the result. Keep a list of medicines and supplements. A [Cholesterol Test](/treatments/diagnostics-and-screening/cholesterol-test/) can clarify the lipid pattern.

Choose regular movement, fibre-rich foods and unsaturated fats more often, and reduce sugary drinks and heavily processed foods. [Nutrition Counselling](/treatments/lifestyle-and-wellness/nutrition-counselling/) can turn these principles into a realistic plan. If your clinician recommends medicine, ask what it targets and how monitoring will work; [Statin Therapy](/treatments/medical-management/statin-therapy/) is one possible cholesterol treatment.

Call emergency services for chest pressure, severe breathlessness, sudden facial drooping, one-sided weakness, trouble speaking or sudden confusion. These may indicate [Angina](/conditions/angina/) or a stroke emergency. Seek prompt medical advice for marked thirst with frequent urination, vomiting, drowsiness or worsening weakness, especially if you are already being treated for diabetes.

Ask whether the blood sugar result suggests further diabetes testing, which cholesterol component needs attention, what your overall vascular risk means, and when to repeat the tests. Clarify whether food, exercise or medication changes should begin before the next review.
