Preparation for review

How to prepare for the examination and use the time with the doctor

A handy list of medications, findings, and questions that facilitates accurate and helpful conversation.

Heart and blood vessels

High blood pressure: what the numbers mean and what to do next

One measurement is not the whole picture. Learn how to monitor your blood pressure and when to seek help.

Diabetes and metabolism

Type 2 diabetes: steps to reduce risk

Prevention

How much movement is enough and how to start safely

Movement includes walking, housework and exercise. The best start is the one you can repeat.

Infections and immunity

Antibiotics: when they help and when they can do harm

Symptoms

Headache: signs you shouldn't wait

Most headaches are not an emergency, but sudden onset and neurological symptoms change the assessment.

Emergencies

Chest pain: when to seek immediate help

Chest pain has many causes, but serious causes cannot be ruled out without a professional evaluation.
