Nosentrik Health Blog exists to help you understand health topics and prepare better questions. It cannot see you, examine you or know your history. This page sets out those limits plainly so that you can use the library in the way it was meant to be used.
Reading, not treatment
Every entry on this site is general information. It is not a diagnosis, a treatment plan or a recommendation for you personally. The same symptom can have very different causes in different people, and only a professional who can examine you and review your history can work out what applies in your case.
If something you read here seems to clash with what your own doctor, nurse, pharmacist, dentist or optician has told you, follow their advice. They know your situation; we do not.
Who writes the entries
Our writers publish under pen names and do not hold medical, dental or optical qualifications. They read public health guidance and patient information carefully and write it up in plain language. That is a useful service, but it is not the same as clinical expertise, and we never present it as such.
Numbers and measurements
Some entries explain how to take measurements at home, such as blood pressure or body mass index. We focus on technique and deliberately avoid giving personal targets. What counts as a normal or worrying number depends on age, conditions and medicines, so please ask your GP or practice nurse to explain your own readings.
We also do not give doses for medicines or supplements. Questions about how much of something to take belong with a pharmacist or prescriber.
Smoke-free products
Entries about vaping and other alternatives are written for adults who already smoke. No nicotine product is risk-free, and none is suitable for people who do not smoke, for anyone under the legal age, or during pregnancy without professional advice. If you want to stop smoking, local stop-smoking services and pharmacists can offer support that fits you.
Clinic technology
When we describe screening equipment or clinic displays, we explain what the technology is for in general. Whether a particular test is right for you, and what its results mean, is a conversation for the clinic that offers it.
When to stop reading and get help
Please contact your local emergency number straight away for chest pain or pressure, sudden severe headache, weakness or numbness on one side of the body, trouble speaking, sudden loss of vision, fainting, severe breathing difficulty or heavy bleeding. Do not wait to check an article first.
For symptoms that are new, persistent or worrying but not an emergency, contact your GP, pharmacist, dentist or optician, or use your local non-emergency health line.
Mistakes and updates
We date every entry and every revision. Health guidance evolves, and despite care, errors can slip through. If you spot something that looks wrong, please let us know through Write to Us. The way we put entries together is described on The People and the Method, and the formal terms of use are on Ground Rules for Readers.
Page or person?
When an entry is not the right tool
General reading helps with background. These pointers show when a person, not a page, should take over.
Keep reading and keep notes
- You want to understand a term a clinic used
- You are preparing questions before a check-up
- You are comparing everyday habits for comfort
Speak to a pharmacist, GP, dentist or optician
- A symptom has lasted longer than you expected
- A new medicine seems to have changed how you feel
- Your measurements keep surprising you
Call for emergency help
- Sudden chest pain, severe breathlessness or collapse
- Abrupt changes in vision or speech
- Bleeding that keeps flowing despite firm pressure
Our writers hold no clinical qualifications, which is exactly why these limits matter.
Read this part first
Use us for understanding, not for verdicts
Each entry is written to help you follow what a clinician says and to arrive with sharper questions. None of them can tell you what is happening in your own body.
When our wording and your professional's advice disagree, trust the person who has actually seen you.
