Checking up on your health: Why do GPs ask so many questions?

Typically, when you visit a GP practice for the first time, you’ll be asked a list of questions. This “New Patient Check” is a free check-up of your overall health. The answers and results can help your GP understand you better and address any current or future health issues.  

The GP health check in the Evergreen Life app asks similar questions and can help YOU get a picture of YOUR health from an NHS viewpoint. The questions fall broadly into 2 types; health measurement type questions like your age, whether or not you smoke, your blood pressure, body mass index, gender and ethnicity. We also include 3 self-rated questions – what you think and feel about your overall health, diet and stress levels. Subjective questions are a very important aspect of measuring health and wellbeing. It’s worth noting that alcohol merits its own check and is not included for that reason.

This article addresses the questions you’ve answered in the GP Check and will help you understand more about your score.

Weighing it up: What is a healthy BMI range?

When you complete the GP check you are asked to enter your height and weight measurements from which your BMI is automatically calculated. Overall, a very high BMI is linked to an increased risk of illness from heart disease and musculoskeletal diseases, as well as reduced life expectancy and impaired mental health.

The National Institute for Clinical Excellence (NICE) generate national guidelines for the UK medical community. NICE 2022 guidelines for categorising BMI now recognise the difference between ethnicities and that certain ethnicities have variations in body composition (i.e. the percentage and distribution of the fat, bone, and muscle in your body), and may carry greater risk of potential health problems at lower BMIs than the usual cut offs.

For people with a South Asian, Chinese, other Asian, Middle Eastern, Black African or African-Caribbean family background the cut offs are:

Healthy weightBMI 18.5 kg/m2 to 22.9 kg/m2
OverweightBMI 23 kg/m2 to 27.4 kg/m2
ObesityBMI 27.5 kg/m2 to 37.4 kg/m2
Severely obeseBMI 37.5 kg/m2 or above

For people whose family background isn’t listed above:

Healthy weightBMI 18.5 kg/m2 to 24.9 kg/m2
OverweightBMI 25 kg/m2 to 29.9 kg/m2
ObesityBMI 30 kg/m2 to 39.9 kg/m2
Severely obeseBMI 40 kg/m2 or above

BMI is an important and commonly used practical measurement for health. When combined with other questions in the health check-up, BMI can give a fuller picture of your health. However, it’s not completely reliable, as it doesn’t distinguish body fat from muscle and bone, so needs to be interpreted with caution. For example, you might be a healthy weight according to your height, but you can still carry too much body fat and could experience some of the same risks as those who are more obviously overweight. For example, a 2024 study found that belly fat, indicated by waist measurements, were a better predictor of colorectal cancer risk than BMI, further illustrating how understanding your body fat and where you store it is key to learning how to maintain a healthy shape overall. Similarly, people who are tall often have higher BMI even though they are fit.

BMI may not be helpful if you are:

  • Muscular, as BMI may not show accurate fat levels.
  • Over 65, due to other health conditions, and possible protective effect of having a slightly higher BMI when older.
  • Pregnant.

Indeed, your waist measurement is a more accurate indicator or predictor of potential health problems than BMI. Some GPs use that measurement in addition.

In fact, NICE 2022 guidelines say that waist-to-height ratio, alongside BMI, is now considered a helpful measurement to predict or indicate potential health issues.

The organisation encourages adults with a BMI under 35 kg/m2 to keep their waist measurement to less than half their height, to reduce their risk of potential type 2 diabetes, hypertension (high blood pressure) or cardiovascular (heart) disease.

So, aim for a waist-to-height ratio of under 0.5. To find out how to measure and calculate yours and what NICE classes as a healthy waist-to-height ratio visit our Body fat. Understanding and reducing it article.

Heart rate

In your patient check, your doctor may carry out some simple tests to gain the first clues into your heart’s function. They may take your pulse in order to check your heart’s rate, rhythm and regularity. Each pulse matches up with a heartbeat that pumps blood into your arteries.  

A very fit person may have a lower heart rate which can be normal and healthy for them.

However, if your reading is less than 60 beats per minute and you don’t consider yourself to be particularly active, it’s advisable to book an appointment to see your GP. A very slow heart rate could be a sign of complications down the road. If your heart rate is over 100 beats per minute on many occasions at rest, it is worth contacting your GP.

Blood pressure: know your numbers

Put simply, blood pressure is the force with which blood moves through your blood vessels. And according to the British Heart Foundation, around 7 million people in the UK are living with undiagnosed high blood pressure, which has knock-on risks of heart disease, heart attacks, stroke and kidney disease.

With all these potential risks linked to high blood pressure, it’s important to understand what your readings mean. You’ll get a reading of two numbers. The higher number is called systolic pressure which is the force at which the heart contracts and blood is pumped through the arteries. Diastolic pressure – the lower number – is the pressure between beats when the heart relaxes. Typical guidelines for a healthy blood pressure range lie between 90-120 for systolic and 60-80 for diastolic.

If your blood pressure is greater than 140 systolic and/or 90 diastolic you should make sure your GP is aware of your reading.

Blood pressure rises as you drink more alcohol. In general, the more you drink, the higher your blood pressure. Over time, binge drinking seems to eventually raise blood pressure permanently. Moderate levels of alcohol within the nationally agreed limits of 14 units a week are not likely to affect blood pressure, but higher levels will probably raise your blood pressure. Other ways of making high blood pressure less likely include losing weight and reducing salt.

No to tobacco

It’s no secret that smoking is bad for your health. In fact, half of all long-term smokers die early from illnesses like cardiovascular disease, lung cancer and chronic bronchitis. And there’s plenty of evidence that there’s still a risk, even if you smoke only a few cigarettes per day. Quitting will let you breathe more easily, give you more energy and help you live longer – at any age.  

Stopping smoking can be easier with the right kind of help. Your pharmacy or GP practice will be very happy to help you. There are lots of effective things you can buy, and you could try other things like coaching or hypnosis.

There’s also a whole host of resources online that can help you on your journey to cutting down on the cigs. There are some useful resources for stop smoking in the references below.

You are what you eat

Eating well is one of the best things we can do to keep ourselves healthy. As well as tasting good, food provides the nutrients, vitamins and minerals and trace elements that our bodies need to function. Our diet and whether it has all the essentials, not only impacts our health but also our energy levels and capacity to enjoy life .

Most people in the UK eat and drink too many calories, too much saturated fat, sugar and salt, and not enough fruit, vegetables, oily fish or fibre. There are links to further reading at the end about what a healthy diet looks like.

Stress

Stress is difficult to define which is why we have asked you to rate it yourself. It’s a natural response and designed to keep us safe short-term but in the long-term it is depleting. Too much stress can affect our mood, our body and our relationships – especially when it feels out of our control. It can make us feel anxious and irritable, and affect our self-esteem.

Experiencing a lot of stress over a long period of time can also lead to a feeling of physical, mental and emotional exhaustion, often called burnout.

Of course, reducing stress is easier said than done.  But, there are steps you can take to help. Firstly, start by identifying the cause of your stress and work on how you can resolve it, dealing with one issue at a time. Also, ensure you’ve got time to relax and unwind, to do the things you enjoy.

If you’re struggling with stress, it’s best to speak to someone. You can discuss with your GP or call : Samaritans free on 116 123 if you want to talk to someone now.

Setting the records straight

Hopefully the GP health check questionnaire has helped you understand areas of your health that you may want to improve.  

With the questions we ask in this GP check, our aim is to help you build a more complete and accurate record of your health – all in the palm of your hand. All this information can be used as an easily accessible reference, so you’ll be able to monitor your health and share it with health providers at the point of care.
