When and how should I use the Isabel Symptom Checker?

When and how should Isabel be used?

Doctors have a vast amount of knowledge to help them, but you are still the person who knows most about you symptoms, and our aim is to make you feel empowered to make suggestions and arrive at a condition together with your doctor. Here are some tips that can help you through the process.

When in doubt


Often conditions are missed because they are either rare, the doctor did not have all the information, or it was simply not thought of. We all too often accept the first condition we are given without questioning it, even if we doubt it is the correct one, and this is the perfect time to use Isabel.

Entering all your symptoms into the Symptom Checker will allow you to research all the possible conditions in your own time, find the one that best fits with your symptoms, and then discuss this with your doctor.

Using Isabel should enable you to say:

"Doctor, I know you think that I have a disease X but could you please
explain why you don't think it could be disease Y or Z which have been
suggested by Isabel and match the symptoms I am experiencing?"


How should Isabel be used?

Isabel, like any symptom checker, will not be able to tell you what your exact condition is. What it can do is suggest some possible conditions based on the symptoms you have entered.

Enter your symptoms in natural language

If you have already seen your doctor about your symptoms, he or she may have told you what the medical terminology is or described them more precisely. If you do not have this, then simply try your best to describe the symptoms that are affecting you.


Start with the most important symptoms


Try to enter the most important and initial symptoms first. You can look at the results, then add others after. This helps you to refine your list of conditions without distorting it with symptoms that may not be as relevant.

Don't be alarmed

When you first see the results you may well be overwhelmed or alarmed, but it is important to remember that Isabel's list of suggestions are just diagnostic possibilities. It is the job of your doctor to work with you to decide which of the conditions are most likely.


How long have you felt unwell?

The common symptoms of cancer are also those of many less serious illnesses which is why cancers will often appear in the list and this can be alarming. The key indicator is how long you have had the symptom for and whether it is getting better or worse. If you have had the symptom for more than 3 or 4 weeks, you should be talking to your doctor.

Knowledge is power


Each condition is linked to various knowledge sources such as the Merck Manual, Medline Plus, Wikipedia, NHS Choices etc. You should read up on each condition to see how well your symptoms fit and then decide whether to discuss the condition with your doctor.
