1. Intended Purpose

The Aryash Patient Health Explainer is intended to help non-pregnant adult patients (18 years and over) in the UK understand health information they have encountered in UK primary care or public health contexts — including investigations, test results, prescribed medicines, common health conditions, and cardiovascular risk. The device is delivered as a modular platform under a single intended purpose: each module covers a distinct area of health information and is released as a version update of the same device.

Content is delivered as on-screen text in UK English, supported by optional audio health guides in English and, where relevant, downloadable infographics.

The Aryash Patient Health Explainer is not validated for use in pregnancy and not for children or young people under 18. The device is not for use in a medical emergency: call 999 first in a suspected emergency, or NHS 111 for urgent but non-emergency concerns.

2. What is the Aryash Patient Health Explainer?

The Aryash Patient Health Explainer is a free web-based tool that helps you understand health information you have encountered in the UK — including investigations and test results, prescribed medicines, common health conditions, and cardiovascular risk. It is available at aryash.health and works on any smartphone, tablet, or computer with a web browser.

It is built as a modular platform, with each module covering a distinct area of health information under the same intended purpose:

It was created by Dr Krishnan Pasupathi (MBBS MBA MRCGP), an NHS GP Partner, and is published by Aryash Health Limited.

What the device does

• Provides plain-English information on investigations, results, prescribed medicines, common health conditions, and cardiovascular risk.
• Where a module accepts data (Module 1): compares a numeric value against UK reference ranges and shows where it sits on a visual scale with NICE / NHS / royal-college-anchored thresholds.
• Displays plain-language information about what a result or finding can commonly mean.
• Shows fictional worked patient examples to illustrate how different scenarios are usually managed in UK general practice.
• Suggests questions the patient can raise with their GP or clinician.
• Provides supporting audio health guides and downloadable infographics.

What the device does not do

• It does not diagnose any medical condition.
• It does not compute cardiovascular risk or other risk scores (Module 2 signposts users to NHS-validated external calculators).
• It does not recommend specific medicines, dosages, or treatments.
• It does not analyse biological samples — it is not an in-vitro diagnostic device.
• It does not store, transmit, or process your name, NHS number, date of birth, or any information that identifies you.
• It does not create or contribute to any medical record.
• It does not replace consultation with your GP or another registered healthcare professional.

3. Important Warnings

4. Who is the device for?

The Aryash Patient Health Explainer is designed for:

• Non-pregnant adults aged 18 years and over who have received health information from their GP, NHS Health Check, hospital, pharmacist, or another registered healthcare professional — or who wish to understand a health concern before seeking care.
• Family members or informal carers helping an adult understand their results, condition, medication, or cardiovascular risk.

The device is not for children or young people under 18 and is not validated for use in pregnancy or the first six weeks after giving birth.

Clinicians may direct patients to the device as a patient-facing explainer. Clinical decision-making remains the responsibility of the treating clinician — the device is not intended for use in clinical decision support.

5. How to Use the Device

5.1 Before you start

You will need:

• A device with internet access (smartphone, tablet, or computer).
• For Module 1 only: your blood test results — a letter, printout, text message, or online record from your GP or lab showing your test numbers and the units.

6.2 Module 2 — Cardiovascular Risk Explainer: Topics Covered

• QRISK3: what the score is, what the risk bands (<10% / 10–20% / >20%) mean, the risk factors QRISK3 uses (modifiable and non-modifiable), and what conversation a given score may prompt with your GP. The module does not calculate the score — it signposts to qrisk.org.
• Cholesterol: LDL, HDL, TC:HDL ratio, triglycerides — what they mean, UK target thresholds, and how statins and lifestyle changes typically affect them.
• Action: smoking, blood pressure, diet, exercise, weight, alcohol, stress — evidence-based ways to lower cardiovascular risk, framed as information to discuss with your GP.

6.3 Module 3 — Heart Health Explainer: Topics Covered

• Conditions: hypertension, atrial fibrillation, heart failure, coronary heart disease, angina.
• Investigations: ECG, echocardiogram, stress testing, angiogram, Holter monitoring.
• Blood tests (cardiac): BNP / NT-proBNP, troponin, cholesterol panels.
• Medications: statins, beta-blockers, ACE inhibitors, anticoagulants, diuretics.
• Lifestyle: diet, exercise, smoking, stress, alcohol, weight, secondary prevention.

6.4 Module 4 — Men's Health Explainer: Topics Covered

• Prostate: PSA testing, enlarged prostate, prostate-cancer awareness, age-related reference tables.
• Testicular: self-examination, lumps, when to seek help.
• Sexual health: erectile dysfunction (including the cardiovascular link).
• Hormonal: testosterone deficiency, when testing is appropriate.
• Mental health: depression, anxiety, when to seek help.
• Screening: UK screening guidance relevant to men.

7. When to Seek Medical Help

If a result, risk band, or symptom is flagged as urgent in any module, or you have any red-flag symptoms listed on a page:

• Contact your GP surgery today, or on the next working day if the surgery is closed.
• If your surgery is closed and you cannot wait, call NHS 111.
• If you also have any of the emergency symptoms listed above, call 999 immediately.
• Do not wait for a routine appointment.

Contact your GP or call NHS 111 if:

• You have symptoms alongside an abnormal result (for example, increased thirst with a high HbA1c, or breathlessness with a raised BNP).
• You are unsure what your result, condition, risk, or symptom means after reading the relevant module.
• Your GP has told you a different target range or plan for your situation.

Book a routine GP appointment to:

• Discuss any result in an amber / "needs attention" band or any new condition, medication, or risk concern raised by the module.
• Ask the questions suggested on each topic page.
• Arrange repeat testing or referral if your GP has recommended it.

8. Your Privacy

• The device does not ask for your name, NHS number, date of birth, or any personal details.
• Any number you enter (Module 1) is used only in your browser to position the scale — it is not saved and is forgotten when you close the page.
• There is no login, no account, and no personal tracking.
• If you use a shared device (for example, a family tablet), your entries are not stored and cannot be seen by the next person.
• For full details, see the Privacy Policy.

9. Technical Requirements

• Internet: Required to load the site and play audio. Once loaded, key pages can be revisited offline through browser caching.
• Browser: Any modern web browser (Chrome, Safari, Firefox, Edge, Samsung Internet).
• Screen size: Works on any screen from a small smartphone upwards.
• No download needed: The device runs in your browser — there is nothing to install.

10. Troubleshooting

11. Limitations

Please be aware of the following limitations:

• The device is validated for non-pregnant adults aged 18 and over only. It must not be used to interpret results, risk, conditions, or men's-health topics for children, young people under 18, or people who are pregnant or in the early post-partum period.
• Reference information is UK general-adult and is not personalised to your specific age, sex, ethnicity, medications, or co-morbidities. Your GP may use different targets — always follow your GP's advice over what the device shows.
• Module 1 looks at one test at a time. It cannot consider how multiple results relate to each other, how your results have changed over time, or how your symptoms relate to your results.
• Module 2 (Cardiovascular Risk Explainer) does not calculate a risk score. For an actual QRISK3 score, follow the link to qrisk.org.
• Worked patient examples are fictional teaching vignettes. They illustrate common UK general-practice management; they are not case reports of real patients.
• The device cannot assess how you are feeling. If you feel unwell, contact your GP, call NHS 111, or call 999 in an emergency — do not wait to check a topic on this device.

12. Contact and Reporting

If you believe the device has given you incorrect information that may have caused harm, please contact us immediately at feedback@aryash.health. We acknowledge reports within 5 working days, investigate promptly under our post-market surveillance plan, and notify the MHRA through the MORE portal where required.

You can also report concerns about the device directly to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk or through the Yellow Card app. Reports can be made by patients, family members, carers, or healthcare professionals. You do not need to contact us first — the two reporting routes are independent.
