Scuba diving is a popular recreational activity that allows individuals to explore the underwater world.
However, for pregnant women, it is important to consider whether scuba diving is safe for both the mother and the developing fetus.
It is also important to note that the information on the safety of scuba diving during pregnancy is limited, and more research is needed to determine safe limits.

Understanding Scuba Diving
Scuba diving is a popular recreational activity that involves exploring the underwater world. It requires the use of specialized equipment, including a scuba tank, regulator, and buoyancy control device.
Scuba diving can be a fun and exciting activity for many people, but it is important to understand the risks involved, especially when it comes to diving while pregnant.
One of the most important factors to consider when scuba diving is the pressure of the water. As a person descends deeper into the water, the pressure increases.
This is because water is much denser than air, and the weight of the water above creates pressure. The pressure is measured in bars, with one bar being equivalent to the pressure at sea level.
When scuba diving, it is important to monitor the pressure and adjust the equipment accordingly. This is because the pressure can affect the body in various ways.
For example, it can cause the lungs to compress, which can lead to difficulties breathing. It can also affect the body’s tissues and organs, causing pain and discomfort.
During pregnancy, the body undergoes many changes, and these changes can affect how the body responds to pressure.
For example, the extra weight of the baby can cause the body to become more buoyant, which can affect the ability to control buoyancy while diving. Additionally, the changes in hormone levels can affect how the body responds to pressure changes.
Given the potential risks, it is generally recommended that pregnant women avoid scuba diving. However, there is limited scientific data on the safety of diving during pregnancy, and some women may choose to continue diving with their doctor’s approval.
It is important to discuss the risks and benefits with a healthcare provider before making a decision.
Physiological Changes during Pregnancy
Pregnancy is a time of significant physiological changes for women. These changes are necessary to support the developing fetus and prepare the mother’s body for childbirth.
Some of the most notable changes include an increase in blood volume, heart rate, and respiratory rate. These changes can have an impact on a woman’s ability to scuba dive safely.
During pregnancy, the placenta plays a crucial role in providing the developing fetus with oxygen and nutrients. As a result, blood flow to the placenta increases significantly, which can lead to a decrease in blood flow to other parts of the body.
This can impact a woman’s ability to tolerate the physical demands of scuba diving, particularly at deeper depths.
Gestation also causes changes in lung function, which can impact a woman’s ability to breathe underwater. As the uterus expands, it can push up against the diaphragm and reduce lung capacity.
This can make it more difficult for a woman to take deep breaths and regulate her breathing while scuba diving.
Additionally, hormonal changes during pregnancy can impact a woman’s ability to scuba dive safely. For example, relaxin, a hormone that helps to relax the pelvic ligaments in preparation for childbirth, can also impact joint stability and increase the risk of injury while scuba diving.
Potential Risks of Scuba Diving While Pregnant
Scuba diving is a physically demanding activity that requires a lot of energy and involves exposure to high pressure environments. The risks associated with scuba diving during pregnancy are not well understood, but there are some potential risks that pregnant women should be aware of.
One of the main concerns regarding scuba diving while pregnant is the risk of decompression sickness. This occurs when nitrogen bubbles form in the tissues of the body due to the rapid changes in pressure that occur during a dive.
Decompression sickness can cause a range of symptoms, including joint pain, fatigue, and shortness of breath. In severe cases, it can lead to paralysis or even death.
Another potential risk of scuba diving while pregnant is the risk of arterial gas embolism. This occurs when gas bubbles enter the bloodstream and block the flow of blood to vital organs.
Arterial gas embolism can cause a range of symptoms, including chest pain, shortness of breath, and loss of consciousness.
There is also some evidence to suggest that scuba diving while pregnant may increase the risk of miscarriage or developmental abnormalities in the unborn baby.
This is because exposure to high pressure environments can cause tissue trauma and nitrogen bubbles to form in the body, which can disrupt normal fetal development.
The Divers Alert Network (DAN) recommends that pregnant women avoid scuba diving altogether, as there is not enough evidence to determine safe limits for diving during pregnancy.
If a pregnant woman does decide to dive, she should be aware of the potential risks and take extra precautions to minimize them. This may include avoiding deep dives, limiting the duration of dives, and using a hyperbaric chamber to reduce the risk of decompression sickness.
Medical Opinions and Research on Diving While Pregnant
Medical opinions and research generally advise against scuba diving during pregnancy due to the potential risks involved.
The American College of Obstetricians and Gynecologists (ACOG) recommends that women avoid scuba diving during pregnancy, as there is a lack of data on the effects of scuba diving on fetal development [1]. The Divers Alert Network (DAN) also advises against diving while pregnant, as well as diving within 24 hours of giving birth [2].
Studies have shown that diving can increase the risk of decompression sickness, which occurs when nitrogen bubbles form in the bloodstream.
This can be dangerous for both the mother and the fetus, as it can lead to fetal distress and miscarriage [3]. Additionally, the oxygen concentration in the body can be affected by the increased pressure underwater, which can be harmful to the fetus [4].
The Undersea and Hyperbaric Medical Society recommends that pregnant women do not participate in hyperbaric oxygen treatment, which is similar to scuba diving in terms of the pressure changes involved [5].
The RSTC Medical Form, which is used to assess a diver’s medical fitness, also includes pregnancy as a contraindication for diving [6].
While there is limited research on the effects of scuba diving during pregnancy, the available evidence suggests that it is not safe.
Pregnant women are advised to consult with their doctor before engaging in any activities that may pose a risk to their health or the health of their fetus.

Precautions and Alternatives to Scuba Diving
While scuba diving can be a fun and exciting activity, it is not recommended for pregnant women. The risks associated with scuba diving while pregnant are not yet fully understood, and there is a lack of research in this area. Therefore, it is recommended that pregnant women avoid scuba diving altogether.
However, there are alternatives to scuba diving that pregnant women can enjoy. Snorkeling is a great low-impact alternative that allows pregnant women to enjoy the underwater world without the risks associated with scuba diving.
It is important to note that caution should still be exercised when snorkeling, and pregnant women should not push themselves too hard or swim too far from shore.
Swimming is another great alternative to scuba diving. It is a low-impact exercise that can be done throughout pregnancy, and it provides a great cardiovascular workout. Pregnant women should wear a wetsuit when swimming in colder waters to keep their body temperature regulated.
If a pregnant woman is still interested in diving, shallow diving may be an option. However, it is important to note that shallow diving still carries risks, and pregnant women should consult with their doctor before attempting any type of diving.
Carbon monoxide poisoning is a risk associated with diving, and pregnant women should be cautious when diving near boats or in areas with high boat traffic. It is important to always monitor for symptoms of carbon monoxide poisoning, such as headache, nausea, and dizziness.
For women who are trying to conceive, it is recommended that they abstain from diving until after they become pregnant. There is a lack of research on the effects of diving on fertility, and it is better to err on the side of caution.
