Diver Medical Form Cozumel: Conditions & Physician Clearance
Learn which health conditions require physician clearance for Cozumel dive certification. Complete guide to the diver medical form, what triggers a 'yes'
Carmen Novelo · October 12, 2026
The diver medical form in Cozumel is a mandatory questionnaire that screens for conditions affecting dive safety — asthma, heart problems, lung conditions, diabetes, ear issues, and pregnancy being the most common flags. The form itself doesn't automatically disqualify you; it identifies when a physician should evaluate whether diving is safe for you, and most recreational divers complete it with no physician visit needed.
Every training agency — PADI, SSI, NAUI — requires you to complete this form before your first confined-water session. If specific answers on the questionnaire indicate potential risk, your instructor will ask you to obtain medical evaluation from a physician before starting your course. Understanding what triggers that requirement helps you plan ahead and avoid surprises on day one.
Key Takeaways
- The diver medical questionnaire is mandatory for all certification courses; certain answers route you to physician evaluation before training begins.
- Common conditions requiring medical evaluation include active asthma, heart disease, seizures, diabetes, perforated eardrum, and pregnancy.
- Obtain physician evaluation at home to avoid losing course time in Cozumel; bring the signed statement with you.
- A 'yes' answer is not automatically disqualifying — it signals your physician should assess your fitness to dive.
- Temporary issues like congestion or an ear infection can delay your course until resolved, even without requiring a physician's evaluation.
Why the Medical Questionnaire Exists
Recreational scuba diving exposes your body to pressure changes, physical exertion, and environments where immediate medical help is unavailable. The medical questionnaire identifies conditions that might make these stresses dangerous. It's a screening tool developed with input from dive-medicine experts to protect students and instructors alike.
Pressure-related injuries are the primary concern. Your lungs, sinuses, and ears must equalize pressure as you descend, so any condition that impairs that process — chronic sinus problems, ear surgery, lung disease — may require medical evaluation. Cardiovascular fitness matters too: diving involves moderate exercise, and stress underwater can elevate heart rate significantly.
I always tell new students to review the form well before their trip. If you think an answer might trigger evaluation requirements, see your physician at home where your medical records are available. A local Cozumel physician can provide evaluation if needed, but they'll work without your full history.
What Happens When Physician Evaluation Is Required
Under current PADI and SSI protocols, the questionnaire routes specific answers to physician evaluation. A positive response does not automatically disqualify you — it means your physician should review the condition and confirm whether diving is medically appropriate. Your doctor will use the designated evaluation process provided by the training agency.
The physician's statement should reference the specific condition and confirm fitness to dive. Your instructor cannot override this requirement when the questionnaire indicates evaluation is needed. This protects both you and the instructor and ensures you're physically prepared for the underwater environment.
Conditions That Commonly Require Physician Evaluation
The questionnaire covers a range of conditions, but a handful account for most physician-evaluation requirements. Knowing these in advance helps you plan your pre-trip medical visit if needed.
Respiratory Conditions
Active asthma — particularly if you've used an inhaler recently or experienced wheezing — typically routes to physician evaluation. The concern is airway restriction underwater, which can interfere with pressure equalization during ascent. Many divers with well-controlled asthma do receive medical clearance to dive.
Chronic bronchitis, emphysema, collapsed lung (pneumothorax), or any lung surgery also trigger evaluation requirements. Your lungs must expand and contract freely to handle pressure changes.
Cardiovascular Issues
Heart disease, angina, heart surgery, irregular heartbeat, high blood pressure, and any history of chest pain on exertion all require evaluation. Diving involves aerobic activity, and underwater stress can significantly increase heart rate.
If you're on blood-pressure medication and your condition is stable, medical clearance is often straightforward. Your physician will confirm your cardiovascular system can handle dive exertion.
Neurological and Seizure Disorders
Epilepsy or any seizure history requires careful physician evaluation. A seizure underwater presents serious risk — maintaining your regulator becomes impossible, and you risk rapid uncontrolled ascent.
Frequent fainting, dizziness, or blackouts also require evaluation, as these conditions pose obvious underwater hazards.
Ear, Nose, and Throat Issues
Any history of ear surgery, perforated eardrum, or chronic ear infections requires evaluation. Equalization is critical to safe diving, and a damaged eardrum or blocked Eustachian tube can make it impossible. Sinus surgery or chronic sinus problems also need physician review.
Even a temporary issue — a head cold, sinus infection, or ear blockage — can delay your course. You won't need physician evaluation for a simple cold, but your instructor will ask you to wait until you can equalize comfortably.
Diabetes
Both Type 1 and Type 2 diabetes trigger evaluation requirements. Hypoglycemia (low blood sugar) underwater is a concern, and managing insulin or medication while diving requires careful planning. Many diabetic divers receive medical clearance, but your physician needs to confirm your condition is stable and you understand monitoring protocols during dive days.
Pregnancy
Pregnancy is a strong contraindication to scuba diving. The risk to the fetus from pressure changes is considered significant. Standard guidance recommends not diving while pregnant.
Behavioral Health and Medications
Mental health conditions like panic disorder, severe claustrophobia, or PTSD may require evaluation if they could affect your ability to stay calm underwater. Some psychoactive medications — particularly those affecting alertness or judgment — need physician review. Depression and anxiety, if well-managed, often receive clearance, but your doctor should confirm stability.
How to Handle the Medical Questionnaire Before Your Trip
Download the form from your training agency's website — PADI and SSI post them publicly — and review it at least a month before your Cozumel trip. If you believe your answers will route to physician evaluation, schedule a visit with your primary care doctor or a specialist. Explain that you're planning scuba certification and need medical evaluation based on the form's criteria.
Bring the form to your appointment so your physician can review the specific questions. If your physician isn't familiar with dive medicine, point them to Divers Alert Network (DAN), which offers resources for medical professionals. In some cases — especially for asthma, heart conditions, or seizures — your doctor may refer you to a specialist.
Get the signed statement and make a digital copy. Bring both the original and a backup to Cozumel. Your dive shop will keep a copy on file.
If You Need Evaluation in Cozumel
If you arrive without a required physician statement, you'll need to see a local doctor. Cozumel has clinics with dive-medicine expertise, but the visit will cost you time and a course day or more. Your physician at home knows your full health history and can address dive-specific questions more efficiently.
Agency Form Comparison
PADI and SSI use similar medical questionnaires developed with dive-medicine input. Both route specific conditions to physician evaluation, and both emphasize that a positive answer is not an automatic disqualification — it signals the need for medical review. The evaluation process is documented in each agency's standards, and physicians follow the designated protocols when assessing dive fitness.
For authoritative guidance, consult PADI's medical resources, SSI's health guidelines, and DAN's dive-medicine information.
Temporary Issues That Can Delay Your Course
Even if you complete the medical questionnaire without triggering evaluation requirements, temporary conditions can pause your training. A head cold, sinus congestion, or ear infection makes equalization difficult or impossible, and diving while congested risks serious ear or sinus barotrauma. Your instructor will ask you to sit out until you're clear.
Sunburn or jellyfish stings, if severe, can also delay water sessions. Dehydration or lack of sleep impair judgment, so show up to your course well-rested and hydrated.
If you're taking over-the-counter decongestants or antihistamines to manage a cold, discuss it with your instructor. Some medications are compatible with diving; others can cause drowsiness.
Being Honest Protects Everyone
Answer the medical questionnaire truthfully. An undisclosed condition that leads to an emergency underwater puts your buddy, your instructor, and yourself at serious risk.
Do:
- Complete the form accurately; instructors can't help you if they don't know your history.
- Speak up if you feel unwell on a course day, even if it seems minor.
- Carry a copy of your physician statement and medication list in your dive bag.
- Update your instructor if your health changes during a multi-day course.
Don't:
- Hide a condition because you're concerned about being turned away.
- Start a course if you're congested, fatigued, or sleep-deprived.
- Push through discomfort underwater — signal your buddy or instructor immediately.
Pre-Trip Checklist for Medical Readiness
- Download and review the diver medical questionnaire at least one month before travel.
- Schedule a physician appointment if your answers indicate evaluation is required.
- Obtain signed physician statement and make digital and paper copies to bring to Cozumel.
- Confirm you're free of colds, ear infections, or sinus issues before your course starts.
- Bring a list of any daily medications and dosages.
- Ensure you're well-rested, hydrated, and have eaten before water sessions.
DAN Membership and Resources
Divers Alert Network (DAN) offers dive-specific insurance that covers emergency evacuation, recompression therapy, and medical treatment related to diving incidents. Many divers purchase DAN membership before traveling, especially to locations like Cozumel where evacuation to a hyperbaric facility might be necessary.
DAN membership includes access to dive-medicine consultation. If you have a condition on the medical questionnaire and need guidance before your trip, you can contact DAN's medical information line for confidential advice about dive fitness. This service is particularly helpful if your personal physician is unfamiliar with dive medicine.
What to Expect on Course Days
On the morning of your first confined-water session, your instructor will review the medical questionnaire with you. This is a safety check. Be ready to discuss any conditions you disclosed, how you're feeling that day, and whether anything has changed.
Your instructor may ask follow-up questions about medications, allergies, or physical limitations. If you feel nervous, tell them — it's better to address anxiety on land. If you're not fully comfortable, many instructors will adjust pacing or add extra skills practice.
Bring your physician statement and any backup documentation in a waterproof bag. Your dive shop will scan or photograph it for their records.
Seasonal Health Factors in Cozumel
Cozumel's tropical climate is generally favorable for diving. During summer months, higher humidity can trigger sinus congestion in some divers. If you're prone to sinus issues, you may prefer the drier season.
Heat and sun exposure during multi-day courses increase dehydration risk. Drink water continuously throughout course days, even if you don't feel thirsty. The intense tropical sun can cause severe sunburn in just a few hours. Apply sunscreen regularly, wear a rash guard, and take breaks in the shade between sessions.
Planning Your Course Timeline
If you know or suspect you'll need physician evaluation, start the process at least two months before your Cozumel trip. Scheduling a doctor's appointment, getting test results, and obtaining a specialist opinion takes time.
If your doctor orders tests — pulmonary function for asthma, an EKG for heart concerns, or bloodwork for diabetes — schedule these as soon as you book your dive course. Results typically take a week or two, leaving you time to obtain the physician statement and prepare for your trip.
Aim to have all documentation in hand at least two weeks before travel to account for unexpected delays.
Communication With Your Dive Shop
Once you've booked your course, you may contact the dive shop about any medical concerns. While the form is confidential, transparency helps instructors plan. If your instructor knows ahead of time that you have a managed condition and have been medically evaluated, they can tailor your course experience appropriately.
Cozumel dive operators understand that many divers have medical histories and use that information to keep you safe and comfortable. A good instructor uses your medical background to teach effectively.
After Your Course: Ongoing Diving Safety
Certification is the beginning of your diving life. As you continue to dive, stay alert to changes in your health. If you develop a new condition after certification — a heart condition, asthma, ear surgery, or any chronic issue — consult your physician and the agency medical questionnaire before diving again.
If you're diving regularly, consider periodic medical check-ups, especially if you're over 40 or have any chronic health condition. Keep a logbook not just of your dives, but of how you felt. Note any discomfort, equalization problems, unusual fatigue, or other symptoms.
Our Recommendation
For a smooth certification experience in Cozumel, treat the diver medical questionnaire as a planning tool. Review it early, obtain any needed physician evaluation at home, and arrive on the island with documentation complete. This approach avoids lost course time and ensures you're physically ready for the underwater environment.
- First-time divers with no medical history: Complete the form online through your chosen agency before your trip; most will not require physician evaluation.
- Divers whose answers route to evaluation: See your physician or a dive-medicine specialist at home, and bring the signed statement to Cozumel.
- Divers with temporary issues: Postpone your course until you're healthy; diving while congested or unwell risks injury.
- Parents of junior divers: Review the form together and address any childhood health issues — especially asthma or ear problems — with your pediatrician before travel.
Handling the diver medical questionnaire proactively ensures your Cozumel certification begins on schedule and focuses on skills and fun, not paperwork and worry.
