If you have symptoms
If you have symptoms, your GP will ask you about them, how long you have had them, whether they are getting worse over time, and how they are affecting your life. They might ask you to fill out a questionnaire about your symptoms and medical history.
Your GP will check whether your symptoms could be caused by other health problem, such as diabetes, or by any medicines you’re taking. They will also check whether your symptoms could be caused by your lifestyle.
Your GP may ask you to keep a diary for a few days to measure how much fluid you are drinking, what type of drinks you are having, how much urine you pass, and how often. The diary may highlight what could be causing your symptoms and may help your doctor find the best treatment for you.
Your GP may ask you for a urine sample to check for blood or infection that could be causing your symptoms. You may need to give more than one sample. If you have an infection your GP will give you a course of antibiotics.
