Pre-Scuba-Diving
Medical Fitness Check in Bali
Answer first: A pre-scuba-diving medical fitness
check is a focused screening that confirms your heart, lungs, ears and
general health can safely handle the physical demands of diving before
you go underwater. In Bali it is easy to arrange as a stand-alone
assessment or as a screening layer inside a comprehensive medical
check-up (MCU). Many dive schools ask you to complete a standard medical
questionnaire, and if you answer “yes” to any health flag, a doctor’s
sign-off is required before you can dive. This check gives you that
clearance — and the peace of mind that goes with it.
Diving is a wonderful reason to be in Bali, whether you are heading
to Nusa Penida, Amed or Tulamben. But it places real stress on the body:
pressure changes, breath-hold effects, cold water and physical exertion
all matter. As the medical advisor for Bali Medical
Checkup, I want you to enjoy the water knowing your body is ready
for it. This guide explains what a dive fitness check covers, who
genuinely needs one, and how to arrange yours through the Sanur Health
Concierge. It is educational, not a substitute for an in-person
examination by a qualified doctor.
Why divers get
screened before descending
Under water, your body works differently. Increasing pressure
compresses gas in your lungs, sinuses and middle ears; nitrogen
dissolves into your tissues and must be released slowly on the way up. A
heart or lung condition that causes no trouble on land can become
dangerous at depth. This is why the recreational dive industry uses a
standardised health screening before certification.
The widely used Recreational Scuba Training Council (RSTC)
Diver Medical form asks about heart disease, lung conditions
such as asthma, recent surgery, ear and sinus problems, diabetes,
epilepsy, pregnancy and medications. If you answer “yes” to any relevant
item, the form directs you to obtain a physician’s evaluation before
diving (Diver
Medical | Participant Questionnaire, RSTC / Divers Alert Network). A
pre-dive fitness check is simply that evaluation, done properly and
unhurriedly.
Who should
book a scuba diving medical check in Bali
Not every diver needs a formal doctor’s sign-off, but you should
arrange one if any of the following apply:
- You answered “yes” to any question on the dive
operator’s medical questionnaire. - You have asthma, other lung conditions, or a history of
collapsed lung. - You have heart disease, high blood pressure, or an irregular
heartbeat. - You have diabetes, epilepsy, or a seizure
history. - You have recurrent ear or sinus problems or recent
ear surgery. - You are over 45 and taking up diving or returning
after a long break. - You are pregnant — in which case recreational
diving is generally not advised.
If you are healthy, young and answer “no” to everything, many
operators will let you dive without a doctor’s letter — but a quick
baseline check is still reassuring, especially before a demanding
trip.
What the fitness
assessment usually includes
A dive medical is more targeted than a general MCU, though the two
overlap. A thorough assessment typically covers:
- A focused history and physical exam, reviewing the
questionnaire flags in detail. - Blood pressure and heart check, often with an
ECG to look at heart rhythm — one of the core
components explained in our guide to what a
full-body check-up includes. - Lung assessment, listening to the chest and, where
indicated, basic spirometry (a breathing test). - Ear, nose and throat check, confirming you can
equalise pressure and that your eardrums are healthy. - A review of any medications and their relevance
underwater.
Because these components sit naturally within a wider screening, a
dive fitness check is often bundled into a
cardiac-and-respiratory focused package. You can see
how targeted screening layers are built in our specialty health screening
overview.
Combining a
dive check with a full-body screening
If you are already in Bali for a longer stay, it often makes sense to
pair the dive clearance with a broader preventive check-up rather than
treating it as a one-off errand. The heart, lung and blood-pressure work
overlaps almost entirely, so you get more value from the same visit.
This is a good moment to consider a full-body medical check-up
that gives you a complete health baseline, not just a dive-day pass.
For divers who visit Bali repeatedly, an annual check that includes
cardiac screening is a sensible rhythm — it keeps both your
certification requirements and your general health in view. Our heart disease risk
check-up guide explains the cardiac tests in more depth.
An honest
boundary: fitness screening, not treatment
A dive fitness check tells you whether it is safe to dive and flags
anything that needs attention first. It is a screening and
clearance service, not treatment. If the assessment uncovers a
condition — say, previously unrecognised high blood pressure or an
abnormal heart rhythm — the right next step is a proper consultation
with a doctor, and diving waits until you are cleared. We deliberately
do not diagnose or treat through this site; our role is to arrange an
accredited, doctor-led assessment and connect you to appropriate care.
When it comes to something as unforgiving as depth, that caution is a
feature, not a limitation.
Arrange your Bali dive
fitness check
If you would like a pre-scuba-diving medical fitness check — as a
stand-alone clearance or folded into a comprehensive screening — the
Sanur Health Concierge can arrange it at an accredited Sanur-area
facility with English-speaking clinicians, and make sure you receive a
report your dive operator will accept. Start with a no-obligation
inquiry on our contact page, or message us on
WhatsApp (wa.me/6281139414563)
with your dive dates and any health questions, and we will help you get
cleared with time to spare.
