Preventive careDiabetes · Blood pressure · Heart

Find it before it finds your family.

Prevayu finds the person in your family most likely to get diabetes, high blood pressure or heart disease, years before a diagnosis. Then a doctor-led team stays with them, week after week, so the plan actually gets followed.

The problem

India finds these diseases late, then loses the people it finds.

The signs we skip

Your body is already
warning you.

Family history is one signal. The body gives others, and we are taught to wait and hope they pass. Knowing which ones matter is half of catching things early.

"It's just gas."

Chest tightness on effort or after meals

Often blamed on the stomach. It can be the heart.

"It's just age."

Always tired, breathless on the stairs

Brushed off as getting older. Can point to the heart, anaemia or the thyroid.

"It's just stress."

Constant thirst, waking at night to urinate

A classic sign of rising blood sugar.

"It'll heal on its own."

Cuts and wounds that heal slowly

Common when blood sugar runs high for a while.

"It's normal for women."

Periods that changed, heavy bleeding, hot flashes

Real hormonal shifts that deserve answers, not a shrug.

"Just body pain."

A small fall that broke a bone

A break from a minor fall can mean bones have thinned. Worth a check.

Chest pain that won't go away, or pain with sweating or breathlessness, is an emergency. Call 108 or go to a hospital now. Don't wait to see if it passes.

These are not diagnoses. The point is to notice, and to ask. When in doubt, ask a doctor. Our guides help you get to one.

Free risk checkTakes a minute

Should you get a blood test for diabetes?

Four questions from the Indian Diabetes Risk Score, a tool built on Indian data that doctors use to decide who to test. It runs on this page. Nothing you enter is sent anywhere.

Checking for
01How old are you?
02What is your waist, measured at the belly button?

No tape at home? Wrap a string or a phone cable around the belly at the belly button, mark it, and lay it along a ruler.

03How active are you, most weeks?
04Do your parents have diabetes?

What Prevayu does

Find. Confirm. Keep.

01 · FREE

Find who is at risk

A three-generation family map, the risk check above for each adult, and a blood pressure and waist reading. It shows who in the family needs attention first.

02 · AT LAB COST

Confirm with the right tests

Only the tests guidelines call for, for the person who needs them. Collected at home by NABL-accredited labs, and billed at what the lab charges.

03 · CARE PLAN

Keep them in care

A named doctor sets the plan. A trained guide checks in every week. The family sees progress, and nobody has to remember alone.

The testsGuidelines first, not packages

A few tests with a reason.
No 90-test packages.

What we check first

  • Fasting glucose and HbA1cSugar now, and over the last three months. HbA1c 5.7 to 6.4% is prediabetes (ADA 2026).
  • Lipid profileCholesterol and triglycerides, the usual starting point.
  • ApoBCounts the particles that clog arteries. It adds most when triglycerides are high, which is common in Indians.
  • Lp(a), once in a lifetimeAn inherited heart risk. The 2026 US lipid guideline says to test it once in every adult.

Only when there's a reason

  • Liver (FIB-4)For people with diabetes or a large waist, to check for fatty liver.
  • Kidney (eGFR and urine albumin)For people with high blood pressure or diabetes.
  • hs-CRPSometimes, to fine-tune heart risk. Not a screening test.

Not by default

Vitamin D, B12 and thyroid tests in healthy adults. Guidelines advise against routine screening, so we only order them when there's a symptom or a reason.

Who looks after you

One doctor. One guide. Every week.

Doctor · registered in India

Sets and signs every plan

Reviews each result and makes every medical decision. You always know their name and registration number.

Guide · trained by our doctors

The weekly check-in

Takes your readings, books tests, reminds, and passes on the doctor's explanation. Guides don't give medical advice of their own.

Your family · kept in the loop

Nobody remembers alone

A short weekly update on readings, tests and what the doctor said, shared with the people you choose.

Why the weekly part matters

A report alone changes nothing. Staying with people does.

Questions

Good to know.

Is the risk check a diagnosis?

No. It's a screening score that tells you who should get a blood test. Only a test, read by a doctor, can tell you if someone has diabetes.

Does the AI give medical advice?

No. India's telemedicine rules say only a registered doctor can advise you personally, and that is how we work. The AI helps your doctor and guide keep up, and answers general health questions.

Who is the guide?

A person trained by our doctors to check in with you every week, take readings and book tests. Guides pass on your doctor's advice; they don't give their own.

Why not a full body checkup?

Big packages test many things healthy people don't need, which leads to more worry and more tests. We start with the few tests guidelines recommend, for the person who needs them.

Is Prevayu only about diabetes?

No. We map everything that runs in your family, from heart disease to certain cancers, weak bones and arthritis, and tell you what can be done early for each. Our first care programme focuses on diabetes, blood pressure and the heart, where acting early is best proven. See the full map.

Do I have to change my doctor?

No. We work alongside your family doctor and send them a one-page summary whenever you want.

How do I reach you?

Write to care@prevayu.com, or join the pilot and we will message you on WhatsApp.

Where is Prevayu available?

Our first pilot is in Visakhapatnam and Bengaluru, for families with parents in Andhra Pradesh. Join the pilot and we'll reach out.
