Dive Medical Form Answers Guide: How to Complete It Honestly

Introduction

Every diver faces the same hurdle at some point—whether booking their first Open Water course or renewing a certification for a trip that’s been postponed too long. That hurdle is the dive medical form. This questionnaire, standard across the Recreational Scuba Training Council (RSTC) and PADI medical statement, asks direct questions about your health history. The goal here is simple: help you complete the form with confidence, know when a physician’s sign-off is needed, and keep your diving safe and legal. No medical advice here, just practical guidance on what each question means and how to answer honestly without shutting down your dive plans prematurely.

Why Honesty on Your Dive Medical Form Matters

Scuba diving puts unusual stress on the body. Pressure changes affect gas spaces, blood flow, and how nitrogen moves through your system. Lying on a medical form doesn’t change those physiological realities—it just hides them from the people trained to keep you safe.

A false answer can have serious consequences. Decompression sickness can be triggered by conditions like a patent foramen ovale (PFO), something you might not know you have but which shows up on the form as a history of heart conditions. Lung overexpansion injuries, like arterial gas embolism, are direct risks for anyone with asthma or a history of collapsed lungs. Cardiac events underwater, even minor ones, are often fatal because help is minutes away.

Then there’s the legal side. A signed dive medical form is a contract. If you lie and get injured, the dive shop, instructor, and training agency may have legal cover to deny claims. Your travel insurance will almost certainly be void. Honesty isn’t a suggestion—it’s a requirement for keeping yourself safe and your trip protected.

What the Dive Medical Form Actually Asks

Most dive medical forms follow the same structure. They’re based on the RSTC standard or the PADI medical statement, with a set of yes/no questions about your medical history. These categories include:

• Respiratory conditions (asthma, bronchitis, tuberculosis, chest surgery)
• Cardiac conditions (heart surgery, angina, heart attack, high blood pressure)
• Neurological conditions (seizures, epilepsy, head injury, stroke)
• Ear, nose, and throat conditions (recurrent ear problems, sinus issues, hearing loss)
• Surgery and hospitalizations (any major surgery or recent hospital stay)
• Medications and drugs (prescription drugs, over-the-counter drugs, recreational drugs)
• Other chronic conditions (diabetes, psychiatric disorders, cancer)

Every question has a purpose. The form isn’t trying to keep you out of the water arbitrarily. It’s screening for known risk factors. Knowing what’s on the form lets you prepare honest answers before you sit down with a pen.

Question-by-Question Answers: A Walkthrough

Here’s a practical walkthrough for the most common yes/no questions on a dive medical form. For each, I’ll explain what the condition means for diving risk and what an honest answer looks like.

• Do you have asthma?
  If you had childhood asthma that’s been inactive for years—no symptoms, no medication—you can answer “No” in many cases. If you have active asthma requiring daily inhalers or have had an attack in the last five years, answer “Yes.” Asthma can cause air trapping and lung overexpansion, so you need a doctor’s clearance to confirm it’s controlled. Divers with asthma might consider a peak flow meter for at-home monitoring between dives.
• Do you have diabetes?
  Type 2 diabetes controlled by diet and oral medication may be cleared for diving. Type 1 diabetes (insulin-dependent) requires a much more thorough evaluation because of the risk of hypoglycemia underwater. Answer “Yes” and expect to provide medical reports.
• Do you have high blood pressure?
  If you take medication and your blood pressure is well-controlled, you can often dive. The concern is uncontrolled hypertension and the medications used—beta-blockers can affect exercise tolerance. Answer “Yes” and bring your medication list. Divers managing blood pressure might find a wrist blood pressure monitor useful for pre-dive checks.
• Do you have ear or sinus problems?
  Recurrent ear infections, perforated eardrums, or sinus surgery all require a “Yes.” Equalizing pressure is tough with scar tissue or blocked passages, and diving with an infection can cause permanent damage.
• Are you taking any prescription medications?
  SSRIs for depression, blood pressure drugs, even some over-the-counter antihistamines can affect diving safety. Answer “Yes” and list every medication. The form doesn’t ask why; it asks what.
• Do you have any heart conditions?
  This covers a lot—heart murmurs, valve problems, arrhythmias, history of heart attack or surgery. Even a “benign” heart murmur needs clearing. Answer “Yes” for any condition.
• Have you ever had a collapsed lung?
  This is a firm “Yes” for anyone with a history of spontaneous pneumothorax. It’s one of the strictest contraindications because of the risk of recurrence under pressure.

The pattern is consistent: if you have any doubt, answer “Yes.” Answering “Yes” doesn’t stop you from diving. It means you need a physician’s clearance. Answering “No” and being wrong puts you at risk of injury or death.

Common Medical Conditions and How to Answer

Some conditions cause more confusion than others. Here’s a deeper look at specific situations and the realistic answer for each.

• Asthma: Controlled vs. Uncontrolled
  If your asthma is mild and intermittent, you may be fine to dive. The key is whether you have symptoms triggered by exercise, cold air, or stress—all three happen underwater. If you answer “Yes,” a doctor will likely perform a lung function test. If your peak flow is good and you’ve had no recent attacks, clearance is common. If you’re uncontrolled, you’ll be advised not to dive.
• Diabetes: Type 1 vs. Type 2
  Type 2 diabetes on oral medication can often be cleared if blood sugar is stable. Type 1 requires a more rigorous protocol: stable control, no hypoglycemic unawareness, and a dive buddy trained in recognizing symptoms. Answer “Yes” for either type.
• High Blood Pressure
  High blood pressure itself is a risk factor for stroke and heart attack underwater. The bigger issue is the medication. Diuretics can cause dehydration. Beta-blockers blunt the heart rate response, making it hard to assess exertion. Answer “Yes” and be ready to discuss your medications.
• Ear Infections and Surgery
  A history of ear infections, tubes inserted as a child, or a perforated eardrum requires careful evaluation. Scarring can prevent equalization. Answer “Yes” and expect an ENT exam before clearance. Travelers with ear concerns might benefit from an ear equalization aid to practice proper techniques.
• Heart Murmurs
  Most heart murmurs are harmless. A few indicate valve problems or PFO. Answer “Yes.” A cardiologist may order a bubble study to check for PFO, which is a known risk factor for decompression sickness.

For every condition, the honest answer is the safe answer. If you’re unsure, ask your dive shop or instructor. They want you to succeed, but they won’t risk your life on a guess.

What to Do If You Answer ‘Yes’ to Any Question

Answering “Yes” isn’t the end of your diving dreams. It’s the start of a straightforward process. Here’s what to do.

1. Don’t panic. Most “Yes” answers result in clearance after a simple doctor’s visit.
2. Contact a dive-trained physician. A general practitioner may not understand diving physiology. You need a doctor familiar with the RSTC form. Many dive clinics and travel medicine centers specialize in dive medicals.
3. Schedule an appointment. Bring the completed medical form, a list of your medications, and any relevant medical records.
4. Get a physical examination. The doctor will perform a basic check: blood pressure, lung function, heart sounds, and ear examination. They may order additional tests if needed.
5. Receive your signed form. If everything is normal, the doctor will sign off. If they recommend further evaluation, they’ll tell you exactly what’s needed.

The whole process often takes less than an hour. Don’t skip this step. A signed form from the right doctor is the only way to dive legally and safely.

Dive Medical Form Answers: Common Mistakes to Avoid

Divers make predictable errors. Knowing them helps you avoid the same traps.

• Lying to save time. This is the most dangerous mistake. A few minutes saved at the shop can lead to a lifetime of medical debt or worse. Honesty is faster in the long run.
• Assuming a condition is resolved. Childhood asthma often disappears, but the form asks if you’ve ever had it. Answer truthfully. The doctor can evaluate whether it’s truly resolved.
• Thinking a GP’s note is enough. Your family doctor may not know the risks of diving. They might sign a form that isn’t valid because they’re not familiar with diving physiology. Use a dive-trained physician or a travel clinic that specializes in dive medicals.
• Ignoring medications. Over-the-counter drugs like antihistamines or decongestants can sedate you or affect equalization. Prescription drugs like SSRIs can lower the seizure threshold. List everything. A waterproof pill organizer can help travelers keep medications sorted and accessible.
• Assuming dental work is irrelevant. A recent tooth extraction can trap air and cause barodontalgia (tooth squeeze). If you’ve had dental work within the last week, consider it a temporary condition.

Each mistake has a simple fix: be honest, get the right doctor, and read the questions carefully.

The Role of Dive Shops and Instructors in This Process

Dive shops and instructors have a specific role in the medical screening process. They aren’t doctors and aren’t trained to evaluate your medical history. Their job is to provide you with the form, watch you sign it, and ensure it’s complete before you start training.

If you answer “No” to all questions, you can sign the form and start diving. If you answer “Yes,” the instructor can’t accept your signature alone. They must see a physician’s signature on the form. This is a regulatory requirement, not a policy choice.

Don’t pressure an instructor to accept a “No” answer if you know it’s false. They’re legally and ethically bound to refuse. A good instructor will guide you toward the right solution: get clearance, then come back and dive.

What If You Have a ‘Temporary’ Condition?

Not all medical issues are permanent. Temporary conditions still need proper handling.

• A cold or sinus infection. You can’t equalize with blocked sinuses or eustachian tubes. The risk is reverse block and ear barotrauma. Wait until you’re fully recovered, then answer “No” if the condition is gone.
• Minor surgery. If you had a small procedure (e.g., mole removal, hernia repair), wait until the wound is fully healed and the stitches are out. Answer “Yes” if the surgery is recent.
• Dental work. A tooth extraction or root canal can create a pocket of air that causes pain at depth. Wait a week or two. Answer “No” once healed.

The guideline is simple: if the condition affects your ability to equalize, breathe, or remain conscious, don’t dive until it’s resolved. If it’s temporary, you can return to the form once you’re healthy.

How to Talk to Your Doctor About Diving

Many doctors have never treated a diver. You might need to educate them a bit. Here’s a checklist for your appointment.

1. Bring the dive medical form. Show it to the doctor. Explain that it’s a standard screening tool.
2. Bring a list of all medications. Include dosages and how long you’ve been taking them.
3. Explain your dive history. If you’re a beginner, say so. If you’ve dived before, mention any incidents or symptoms.
4. Describe your concerns. Be specific. “I have asthma and I want to know if I can dive with it.” The more details you give, the better the advice.
5. Ask the right questions. “What are the risks of this condition underwater?” “Does my medication affect my ability to dive?” “Is there a time delay I should consider?”

If your doctor seems unsure, ask for a referral to a dive medicine specialist. Dive medical centers and travel clinics have doctors trained in dive medicals who understand the physiology.

Your Next Step: Book Your Dive Medical Clearance

You now have the knowledge to complete your dive medical form honestly. The next step is getting that clearance if you need one. Don’t let a small hesitation stop your dive trip. Book an appointment with a dive-trained physician or a travel clinic that handles dive medicals. It’s quick, safe, and the responsible choice. Once you have the signed form, you can focus on the diving ahead.
