Nobody wants a doctor’s visit to ruin a diving holiday, but a short medical check before you go can protect it. This guide focuses on medical fitness to dive specifically for travelers learning or diving in El Nido, a remote area where medical facilities are limited and a problem on the boat is far from a hospital. It explains the dive medical form, common conditions that need a doctor’s opinion, ear and sinus care, and what to pack and ask before your first dive.

Why a Dive Medical Matters More in a Remote Destination
Scuba diving is safe for most healthy people, but the underwater environment places unusual demands on the lungs, ears, heart and circulation. Pressure changes can worsen certain conditions, and a problem that is minor on land can become serious at depth. In El Nido, boat trips often take you an hour or more from town, and specialist care is not always nearby. That makes prevention far more valuable than treatment.
Doing your homework before you travel also saves money and time. If a doctor needs to sign off on a condition, it is much easier to arrange that at home than on holiday. For general health planning, see our guides to health and medical care in El Nido and health and vaccinations.
The Dive Medical Questionnaire Explained
Almost every dive operator asks you to complete a medical statement before a course or guided dive. Many agencies use a standard questionnaire developed with medical advisers. It asks about asthma, heart disease, diabetes, ear and sinus problems, epilepsy, fainting, lung conditions, pregnancy, recent surgery and certain medications. If you answer yes to any question, you will usually need a physician’s written approval before diving.
Be honest. The form exists to protect you, and operators who ignore it put you and others at risk. If you are unsure how to interpret a question, ask your dive shop or a physician who has experience with diving medicine. Agencies such as PADI publish their forms and guidance online, and Divers Alert Network provides educational articles for divers and doctors.
Conditions That Usually Need a Doctor’s Opinion
The list below is a guide, not medical advice. Always consult a qualified doctor for your specific situation.
| Condition | Why it matters underwater | What to do |
|---|---|---|
| Asthma or wheezing | Air trapping risk during ascent | See a doctor before booking; do not dive if symptomatic |
| Heart or blood pressure conditions | Exertion and cold can strain the heart | Obtain medical clearance |
| Diabetes | Low blood sugar is hard to manage underwater | Discuss a management plan with your doctor |
| Ear or sinus problems | Pressure injuries such as barotrauma | Do not dive with a blocked nose or ear pain |
| Epilepsy or seizures | Loss of consciousness underwater is dangerous | Needs specialist assessment |
| Recent surgery or illness | Healing and fitness may be incomplete | Wait for clearance |
| Pregnancy | Risks to the unborn baby are not well understood | Diving is not recommended |
If your doctor is unfamiliar with diving, ask them to consult guidance from a diving medicine specialist, or consider booking a consultation with a doctor who understands hyperbaric medicine.
Ears, Sinuses and Equalization
Ear and sinus trouble is the most common reason for cancelled dives. If you are congested, have a cold or hay fever, or find equalization difficult, postpone your dive. Forcing equalization can cause barotrauma, which may keep you out of the water for days or longer. Practice gentle equalization on land before the trip: pinch your nose and blow softly, or swallow and move your jaw. Start equalizing early and often during descent, and stop if you feel pain.
Avoid using decongestant sprays or tablets to mask symptoms. They may wear off at depth and leave you with a reverse block. If you wear earplugs for swimming, do not use them for diving, because they trap air and increase pressure on the eardrum. Our guide to open water diving in El Nido explains how local courses introduce these skills step by step.
Medication, Alcohol and Lifestyle
Tell your instructor about any medication, including seasickness tablets. Some drugs cause drowsiness, change heart rate or affect how you handle pressure. Do not start a new medication immediately before diving, and ask your doctor whether your current prescriptions are compatible with diving.
Avoid heavy drinking the night before. Alcohol dehydrates you and affects your judgment and coordination. Drink water through the day, protect yourself from sun and heat, and sleep well. Smoking and vaping also reduce lung efficiency, which is another reason to rest on dive days. If you are anxious about the water, tell your instructor so they can adapt the pace; anxiety is manageable but dangerous if ignored.
Your Pre-Trip Medical Checklist
- Read the dive medical questionnaire in advance and answer honestly.
- Book a doctor’s visit if any answer is yes, ideally several weeks before departure.
- Ask your doctor to confirm any medication is safe for diving.
- Practice gentle ear equalization at home.
- Buy travel insurance that covers diving, medical care and evacuation.
- Save your dive shop’s emergency contact and the nearest clinic address.
- Pack basic items: seasickness remedies if recommended by a doctor, ear care products approved by your doctor, a first aid kit and sun protection.
Print or save digital copies of your medical clearance, certification card and insurance policy. If you lose access to phone signal offshore, paper copies still help; offline maps and contact lists matter too.
Medical Facilities and Emergency Planning in El Nido
El Nido has local clinics and a health center for common problems, but serious emergencies may require transfer to larger hospitals elsewhere in Palawan or beyond. Recompression chambers are limited in the Philippines and not located near every dive area, so ask your dive shop how emergencies are handled, whether they carry emergency oxygen, and which hospital they would contact. Our hospital and medical guide lists what to know about local care.
On a boat day, tell a travel companion where you are going and when you expect to be back. If something feels wrong after a dive, say so immediately, and do not wait to see if it passes. This is also why you should avoid flying soon after diving; read our how-to on no-fly time after diving.
Fitness, Age and Special Situations
You do not need to be an athlete to dive, but you should be able to swim comfortably, handle gear and cope with mild exertion such as carrying equipment onto a boat or swimming against a light current. Basic cardiovascular fitness makes a real difference in an emergency, so start light exercise a few weeks before your trip if you are out of practice.
Age alone is rarely a barrier, though children and older divers may need extra medical consideration. Junior programs have minimum ages and depth limits, and divers over middle age should think carefully about heart health and consider a medical review. Travelers with recent illnesses, including infections, should wait until they are fully recovered. If you have had a head injury, lung surgery or a collapsed lung, you need specialist advice before any dive. Keep your documents handy and remember that a doctor’s clearance is a snapshot in time: if your health changes between the appointment and the trip, update your operator and, if necessary, your doctor.
Questions to Ask Your Dive Shop Before You Book
A short conversation with your operator reveals a lot about their standards. Ask how they screen medical forms, whether an instructor or guide with first aid and oxygen training is on every boat, how far the dive sites are from town, and what the plan is if someone needs urgent care. Ask about group size, because smaller groups mean more supervision. Also ask what happens if you need to cancel a dive for health reasons: good shops offer a refund or a reschedule rather than pushing you to dive.
These questions are routine for experienced operators, and they will be glad to answer. If you receive vague answers, consider another shop.
Choosing a Dive Operator With Safety in Mind
Look for operators who check your medical form, brief you thoroughly, maintain equipment, carry oxygen and a first aid kit, and keep group sizes manageable. Ask about instructor qualifications and safety procedures, and trust your instincts if something seems careless. Our review of dive shops in El Nido and the comparison of PADI vs SSI will help you shortlist.

When to Skip a Dive
Learn to call off a dive without guilt. Skip it if you feel unwell, have a cold or blocked ears, slept badly, drank heavily the night before, or feel pressured by schedule. Good operators respect that decision and will offer a different activity. Remember that the same conditions can improve in a day or two, and El Nido offers plenty of ways to enjoy the sea from the surface in the meantime. Check conditions in advance with the weather agency PAGASA.
Frequently Asked Questions
Do I need a doctor’s note to dive in El Nido?
Only if you answer yes to any question on the dive medical form. Operators then usually require written approval from a physician before you dive.
Can I dive with asthma?
It depends on severity and control. Some people with well-controlled asthma are cleared, but you need a doctor’s assessment before booking.
Can I dive with a cold?
No. Congestion makes equalization difficult and risks barotrauma. Wait until you are fully recovered.
Is it safe to take seasickness tablets before diving?
Ask your doctor or pharmacist first, because some medicines cause drowsiness. Do not try a new medicine for the first time on a dive day.
What if I am pregnant?
Scuba diving is not recommended during pregnancy. Snorkeling at the surface may be possible after talking with your doctor.
Where is the nearest hospital?
El Nido has a health center and clinics, but serious cases may need transfer to larger hospitals elsewhere in Palawan. Ask your dive shop for their emergency plan.
