The Importance of The Medical Questionnaire When Diving

The Importance of The Medical Questionnaire When Diving - La Galigo Liveaboard

Diving is a popular recreational activity that allows individuals to explore the underwater world. However, it is important to ensure that individuals are in good health before engaging in diving activities. One of the crucial components of this health assessment is the medical questionnaire. This document serves as a screening tool to identify any potential risks or conditions that may affect a diver’s safety underwater. In this article, we will explore the importance of the medical questionnaire in diving and how it contributes to overall diver safety.

What is Medical Questionnaire

A medical questionnaire is a vital tool used to assess a diver’s fitness for diving. It typically includes questions about the diver’s medical history, current health status, and any pre-existing conditions that could impact their safety underwater. This questionnaire helps dive operators and instructors to understand the diver’s health background and determine if they have any medical conditions that may pose risks during a dive. Answering the questions in the medical questionnaire accurately and honestly is crucial for the safety of the diver and their diving companions.

Specific Questions in a Medical Questionnaire for Divers

Cardiovascular Health

The medical questionnaire includes inquiries about the diver’s cardiovascular health, aiming to uncover any past or current heart conditions, surgeries, or family history of cardiovascular issues. This information is crucial in identifying potential risks related to PFO and other cardiovascular conditions that could pose a threat during diving.

Respiratory System

Questions regarding the diver’s respiratory health are also included in the medical questionnaire. Any history of lung diseases or breathing difficulties can indicate heightened risks while diving, especially in relation to decompression sickness.

Neurological and Ears Nose Throat Health Factors such as a history of migraines, seizures, or ear problems are significant components of the questionnaire. These issues can be associated with conditions that may worsen during diving and even contrast with diving safety.

Previous Diving Experiences

The questionnaire also encompasses questions about the individual’s previous diving experiences and any incidents or adverse health effects encountered during diving. This insight provides valuable information to evaluate the diver’s response to underwater conditions and helps in determining their suitability for future diving activities.

Medication and Substance Use

The medical questionnaire includes a section for documenting any current medications, as well as alcohol or drug consumption. This is essential as certain medications and substances can exacerbate the risks associated with diving or negatively interact with the underwater environment. It’s very important here to answer honestly, even if that includes disclosing illicit drug use to your doctor. In most countries this is confidential and the doctor needs this information for your safety. 

Reviewing the Results of The Medical Questionnaire

In the following section, we will discuss the role of a medical professional in reviewing and interpreting the responses from the questionnaire, emphasising the importance of seeking expert medical advice before engaging in diving activities.

Patent Foramen Ovale (PFO)

One specific condition that the medical questionnaire helps to identify is Patent Foramen Ovale. This is a congenital heart defect that involves a small opening in the wall between the upper two chambers of the heart.

Individuals with an undiagnosed PFO may be at risk of experiencing decompression sickness or arterial gas embolism during diving. The medical questionnaire plays a crucial role in detecting PFO and other such conditions, thereby ensuring the safety of divers.

Gastroenteritis with Vomiting and Diarrhoea

In the context of diving, it is crucial for divers to disclose any recent illnesses or health issues, such as gastroenteritis with vomiting and diarrhoea, on their medical questionnaire. Gastroenteritis can lead to dehydration and weakness, which can compromise a diver’s ability to handle the physical demands of diving. Additionally, the presence of vomiting and diarrhoea can increase the risk of an underwater emergency and jeopardise the safety of the diver and their diving team.

Therefore, it is important for divers to fully disclose any recent health issues when filling out a medical questionnaire. This allows dive operators and instructors to make well-informed decisions about the diver’s fitness for diving, ensuring the safety of everyone involved. By being transparent about their health status, divers contribute to a culture of safety and responsibility in the diving community.

Chronic Reflux

Suffering from chronic reflux can be especially problematic for divers. The pressure changes experienced during diving can exacerbate reflux symptoms, leading to discomfort and potential complications. It is crucial for divers with chronic reflux to disclose this condition on their medical questionnaires before diving. By providing accurate and thorough information, divers can ensure their safety and the safety of those around them while exploring the wonders of the underwater world.

Liver Cirrhosis

Liver cirrhosis is another condition that poses significant risks for divers. The changes in pressure and the physical exertion involved in diving can exacerbate the symptoms of cirrhosis, leading to fatigue, weakness, and increased risk of injury. It is imperative for individuals with liver cirrhosis to carefully consider the potential risks of diving and disclose their condition on the medical questionnaire. Open and honest communication with dive instructors and medical professionals is essential to make an informed decision about whether diving is safe with this condition. Safety should always be the top priority when it comes to underwater activities.


Anaemia is a condition that can significantly affect a diver’s ability to safely participate in diving activities. The reduced oxygen-carrying capacity of the blood in individuals with anaemia can lead to increased fatigue, dizziness, and even fainting, especially under the physical exertion and pressure changes experienced during diving. It is important for individuals with anaemia to carefully consider their condition before engaging in diving and to honestly disclose this information on their medical questionnaires.

Moreover, seeking the advice of a healthcare professional to assess the severity of anaemia and its potential impact on diving safety is crucial. With proper guidance and understanding of the condition, individuals can make informed decisions about their suitability for diving activities. Safety measures and accommodations can also be discussed to ensure a safe and enjoyable experience for everyone involved. Remember, prioritising safety and clear communication is paramount when it comes to addressing medical conditions and engaging in underwater exploration.

Respiratory Conditions

Individuals with respiratory conditions such as asthma need to be particularly cautious when considering diving. The changes in pressure and the potential exposure to irritants in the water can trigger asthma symptoms and lead to breathing difficulties. It is essential for individuals with asthma to disclose this condition on their medical questionnaires and seek guidance from medical professionals and experienced dive instructors to assess the potential risks and safety considerations associated with diving.

Additionally, discussing the use of appropriate medications and inhalers during diving activities can be crucial in managing asthma symptoms and ensuring a safe diving experience. Attention to detail and clear communication about the specific nature of the respiratory condition can lead to the implementation of necessary precautions to mitigate risks and optimise safety.

Diabetes Management

For individuals with diabetes, careful consideration and thorough planning are essential before engaging in diving activities. Fluctuations in blood sugar levels, physical exertion, and the potential effects of pressure changes can all impact the management of diabetes while diving. It is vital for individuals with diabetes to candidly discuss their condition on their medical questionnaires and consult with healthcare professionals to develop a comprehensive plan for managing blood sugar levels during diving.

Educating dive buddies and instructors about the signs and symptoms of hypo- and hyperglycemia, as well as establishing clear communication about emergency protocols, can contribute to a safer diving environment for individuals with diabetes. Adhering to proper dietary guidelines and monitoring blood sugar levels diligently are critical components of ensuring a safe and enjoyable diving experience while managing diabetes.

Remember, open and honest communication on medical questionnaires, along with proactive engagement with healthcare professionals and dive instructors, is vital for individuals with medical conditions to make informed decisions about their suitability for diving. Safety and preparation are paramount in enjoying the underwater world while prioritising personal health and well-being.
