What Happens If You Fart While Scuba Diving? The Unspoken Truth

what happens if you fart while scuba diving

Beneath the ocean waves, you’re blissfully scuba diving, admiring the vibrant colours and dazzling life that the underwater world has to offer. Suddenly, as you swim through this enchanting world, you’re struck with a pressing question: what happens if you fart while scuba diving?

While it may seem like a frivolous topic to discuss, it’s a legitimate question that many divers have asked. Not only does it involve matters of basic human decency and manners, but it also covers concerns regarding safety and potential underwater hazards. So, what’s the truth about farting underwater? Well, let’s dive right into the details!

As it turns out, you can actually fart while scuba diving, and it’s generally safe to do so. Farts while diving are often a result of changes in pressure within your body brought about by the depth underwater.

In fact, you’ll likely find that you don’t even feel the urge to pass wind beyond a certain depth. However, the noise of your underwater flatulence can be louder and travel farther than it would on the surface, so bear in mind the potential embarrassment when releasing gas among your fellow divers!

Dry Suit Vs. Wet Suit

While the topic of farting while scuba diving may seem humorous, it actually highlights an important difference between dry suits and wetsuits.

Wetsuits are made of neoprene material that is designed to trap a thin layer of water between the suit and the diver’s skin. The water is then warmed by the diver’s body heat, creating a layer of insulation that helps to keep the diver warm.

However, this layer of water also allows gas bubbles to escape through the pores or openings in the suit. When a diver farts in a wetsuit, the gas will typically escape through the suit and rise to the surface.

Dry suits, on the other hand, are made of impermeable material that does not allow water to penetrate the suit. Instead, dry suits are designed to keep the diver completely dry by sealing the suit at the neck, wrists, and ankles.

While this can make it slightly more challenging to expel gas from the suit, it is still possible to do so by using the suit’s valves.

Overall, the choice between a dry suit and a wet suit comes down to personal preference and the conditions in which the diver will be diving. Dry suits are typically used in colder water or in situations where the diver needs to stay completely dry, while wet suits are more commonly used in warmer water or for shorter dives.

Regardless of the type of suit, it is important for divers to follow proper safety protocols and to be aware of their bodily functions while underwater.

Depth and Farting

Depth and Farting

The depth at which you’re scuba diving can impact the speed at which gas bubbles disperse. This is due to the water pressure causing air bubbles to move faster, leading to faster dispersion of gases like hydrogen sulphide.

Can Scuba Diving Make You Gassy?

Scuba diving can indeed lead to an increased urge to pass gas, as the pressure changes might affect your digestive system. However, this experience varies from person to person and should not be a cause of worry.


Some symptoms you may experience if you feel the need to fart while scuba diving include stomach cramps, bloating, and discomfort. And while it might be embarrassing for some divers, farting underwater is a natural bodily function.

Gastric Squeeze Vs. Decompression Sickness

Gastric squeeze and decompression sickness are two distinct medical conditions that can occur during scuba diving.

Gastric squeeze, also known as barotrauma of the stomach, occurs when a diver’s stomach is not properly equalised during a rapid ascent. The pressure inside the stomach increases, causing discomfort, pain, and potentially leading to injury. Symptoms may include nausea, vomiting, and bloating.

Decompression sickness, also known as “the bends,” occurs when a diver ascends too quickly, causing nitrogen bubbles to form in the bloodstream. This can lead to a range of symptoms, including joint pain, fatigue, dizziness, and shortness of breath. In severe cases, it can be life-threatening.

While both conditions can be serious, decompression sickness is generally considered to be the more dangerous of the two. It is important for divers to follow proper safety protocols and to ascend slowly and carefully to minimise the risk of both gastric squeeze and decompression sickness.

While farting underwater is generally harmless, extreme cases may lead to complications like gastric squeeze, which is caused by increased pressure on the stomach, leading to discomfort, pain, and difficulty in equalising. It’s important to differentiate it from decompression sickness; if you experience difficulty in equalising your ears or any other health problem, consult your instructor and consider rescheduling your dive.

Does Farting in My Wetsuit Affect My Buoyancy?

Does Farting in My Wetsuit Affect My Buoyancy?

Farting in your wetsuit may not significantly affect your buoyancy. However, the release of gas may result in some slight adjustments to your diving position, but it’s unlikely to cause any major disturbances.

Tips to Prevent Farting While Scuba Diving

To reduce the likelihood of farting while scuba diving, consider the following tips:

  • Monitor your diet: Avoid consuming gas-producing foods like beans and carbonated beverages. Stick to a balanced diet with easily digestible items.
  • Exercise regularly: Engaging in regular exercise can help improve your digestive system, reducing the likelihood of gas buildup.
  • Avoid air swallowing: Be mindful of habits that lead to air swallowing, such as chewing gum or smoking, as they can contribute to increased gas.

Remember, farting while scuba diving is an entirely normal bodily function, and there’s no reason to be overly concerned. However, if it becomes a significant issue, it may be worthwhile to discuss with your instructor and possibly adjust your diving habits.

And always keep in mind the guidelines for safe diving, such as equalising pressure, ascending slowly, and avoiding hazardous underwater environments.

Frequently Asked Questions

FAQs farting while scuba

Can you pass gas underwater?

Yes, you can fart while scuba diving. In fact, it’s quite normal for divers to pass gas underwater due to the pressure changes experienced during descent and ascent. Don’t worry, the smell dissipates more quickly underwater, so feel free to let one rip!

Does farting affect buoyancy?

Farting in your wetsuit won’t affect your buoyancy much, as the gas released is minimal in comparison to the air in your buoyancy control device (BCD). So, don’t fret about floating to the surface unexpectedly due to a cheeky toot!

Is it harmful to fart in a wetsuit?

There’s no harm in farting in a wetsuit while diving. Just be aware that if you’re wearing a drysuit, the gas will be trapped inside, so smart divers should “vent” away from their buddies upon surfacing.

Can farting cause bubbles?

Depending on the tightness of your wetsuit or drysuit, farting might cause small bubbles to escape. However, these bubbles won’t cause any harm or reveal your scuba secret to your buddies.

Does underwater farting pose risks?

While holding in a fart can cause discomfort or pain, letting one loose underwater does not pose any significant risks. In fact, it’s better for your health to release the gas than to hold it in and risk overstressing your body.

How to handle bodily functions while diving?

Aside from breaking wind, there are a few other aspects of managing bodily functions while diving. Remember to monitor your hydration levels to ensure optimal comfort and alleviate risks of decompression sickness. Moreover, empty your bladder and bowels before a dive to avoid any unwanted surprises.

Finally, if you use the restroom underwater, pay special attention to your surroundings and currents – no one wants to be “that diver”!
