Can I Get Scuba Certified With a Medical Condition? The Complete Clearance Guide

You've got an inhaler in your gear bag or a glucose meter in your carry-on, and somewhere along the way someone told you scuba diving just isn't in the cards for people like you. That's usually not true. Most divers with asthma, diabetes, or another manageable health condition get certified every year, and the process is more straightforward than the internet makes it sound. This guide walks through the medical form you'll fill out, what "needs a doctor's sign-off" means in practice, and how Dive Arizona handles it when a form comes back with a flag on it.

The Medical Form Every New Diver Fills Out

Before your first pool session, you'll fill out the Diver Medical Participant Questionnaire, a form built jointly by DAN, the World Recreational Scuba Training Council, and the Undersea & Hyperbaric Medical Society, and used across the industry, including by SDI, the agency Dive Arizona certifies through. It's not a pass or fail test. It's a screening tool, and for most people it's ten questions, a page of "no" answers, and a signature.

Three of those ten questions require a doctor's evaluation the moment you answer yes, no follow-up needed: currently taking one or more prescription medications, surgery within the last 12 months (or ongoing problems from an older one), and struggling with moderate exercise, like walking a mile in under 14 minutes or swimming 200 meters without stopping.

The other seven questions work differently. A yes routes you to a more detailed set of follow-up questions about that specific area, and it's your answer there, not the first question, that decides whether you need to see a doctor at all. Plenty of divers answer yes to one of those seven and no to every follow-up question underneath it, and sign the form themselves without ever picking up the phone.

What Requires a Physician's Sign-Off

Here's what those seven follow-up areas cover, in plain language:

Problems with your lungs, breathing, heart, or blood, including asthma, chest pain, or an implanted device like a pacemaker
Being over 45 with a heart risk factor, like smoking, high cholesterol, high blood pressure, or a family history of early heart disease
Problems with your eyes, ears, nasal passages, sinuses, or teeth, including recent surgery or still healing from a dental procedure
A history of head injury, seizures, migraines, blackouts, or a neurological condition
Ongoing treatment for a mental health condition, panic attacks, addiction, or a learning or developmental disability
Back problems, hernia, ulcers, or diabetes
Stomach or intestinal issues, including GERD, Crohn's, or recent diarrhea

None of these are automatic disqualifiers, and answering yes to the general question doesn't mean you're stuck seeing a doctor. It just means the form asks a few more specific questions about that particular area, and it's a yes on one of those that calls for an evaluation. The standard your instructor is trained to check is simple: are you fit for moderately hard physical activity in the water, and can you clear your ears and equalize without a hidden risk. A doctor who knows your history is the right person to answer that, not a form.

One note that isn't part of the evaluation process at all: the guidance for pregnancy is direct, not conditional. If you're pregnant or trying to become pregnant, the recommendation is not to dive, full stop. That's not something a physician's sign-off gets you around.

Asthma and Diving: What a Sign-Off Involves

Asthma is one of the most common reasons people assume they're disqualified before they've even asked, and it's usually the easiest to clear. The actual follow-up question only flags asthma, wheezing, or allergies if a flare-up has limited your physical activity within the last 12 months, so plenty of well-managed asthmatics answer no and never see a doctor over it. If it has come up in the last year, a physician evaluating you is checking whether it's well controlled, how often you reach for your inhaler, and whether exercise or cold air tends to trigger an attack. Some doctors run a simple breathing test in the office. Divers whose asthma is managed well and hasn't limited them recently usually get cleared without much back and forth.

Diabetes and Diving: What a Sign-Off Involves

The same logic applies to diabetes, which shows up on the form alongside back problems, hernia, and ulcers as one category, whether it's diet controlled, managed with medication, or gestational diabetes within the last 12 months. A physician is looking at how consistently your blood sugar stays in range, whether you have good awareness of when you're going low, and whether you've had any diabetes-related complications that would affect circulation or nerve function. Divers who manage their diabetes well, whether through diet, oral medication, or insulin, are certified and diving all over the world. Your doctor is the one who can confirm your specific case fits that picture.

What Happens If Your Doctor Has Questions, or Says Not Yet

A "not yet" is not the same as a permanent no, and it's more common than a flat refusal. Sometimes a doctor wants a follow-up test, a few more weeks of stable control, or a specialist's opinion before signing. If your own physician isn't sure how to evaluate you for diving specifically, Divers Alert Network runs a medical information line staffed by doctors who specialize in exactly this question, and it's a resource we point students to often.

If you're in that in-between spot, you don't have to sit on the sidelines while it gets sorted out. Booking a Scuba Discovery session lets you get in the pool with an instructor for $59, gear included, while the paperwork side gets settled separately.

How Dive Arizona Handles Medical Clearance

When you enroll in the Open Water course or a Discovery session, the medical form is part of enrollment, filled out here at the shop in Queen Creek before you ever get in the water. If something on it needs a doctor's signature, we walk you through exactly what that means the same day, not after you've already paid and started wondering. There's no upcharge for needing a sign-off and no different standard depending on your situation. Certification means you can safely do everything the course requires, and that call is made the same way for every student who walks through the door.

If you already know you have a condition on that list and want to talk it through before you book anything, reach out to us directly. We'd rather answer the question up front than have you talk yourself out of trying before you've even asked.

Frequently Asked Questions

Can I get scuba certified if I have asthma?

In most cases, yes. A physician needs to confirm your asthma is well controlled and that you're not relying on a rescue inhaler frequently. Divers with managed asthma are certified and diving regularly.

Can diabetics get scuba certified?

Yes, with a physician's evaluation confirming your blood sugar is well controlled and you're aware of the signs of a low. Many certified divers manage diabetes through diet, oral medication, or insulin.

What is the RSTC medical form?

Officially it's called the Diver Medical Participant Questionnaire, built jointly by DAN, WRSTC, and the Undersea & Hyperbaric Medical Society and used across the scuba industry, including by SDI. Most people answer no to every question and sign it themselves with no doctor visit required.

Do I need a doctor's note every time I take a new course?

No. If your health hasn't changed since your last certification, you typically don't need to repeat the medical screening. A new or worsening condition is what triggers another look.

What if my doctor won't sign off?

It's usually a "not yet" rather than a permanent no. Divers Alert Network staffs a medical information line specifically for these questions and can often help you and your doctor sort out next steps.

Does having a health condition cost more to get certified?

No. Course pricing is the same for every student regardless of medical history, and certification standards don't shift based on anything other than whether you can safely meet them.

What if I'm pregnant?

The guidance here is direct rather than conditional. If you're pregnant or trying to become pregnant, the recommendation is not to dive. It isn't something a physician's evaluation can clear you for.

Let's Get This Sorted Before It Becomes a Reason to Wait

Most people who think a health condition rules them out never call to ask, and the ones who do usually find the answer is a quick doctor's visit rather than a closed door. If you've got a condition on that list and you're on the fence, book a $59 Discovery session to see how it feels in the water, or start with the full Open Water course if you're ready to go all in. And if you'd rather just ask a real person first, check our FAQ page or call the shop. We've had this conversation more times than you'd think, and it almost always ends with someone diving.
