Impact of Scuba Diving on Bowel Movements

Scuba diving has several effects on the diver’s bowel movements. Below are some of the negative gastronomical problems a swimmer may experience when scuba diving:

  • Abdominal Cramps

When scuba diving, the body experiences water pressure that may create air spaces in the digestive system. The impact affects gas production and may cause bloating and abdominal cramps.

Physical exertion may also reduce the blood flow to the intestines, hampering digestion. The slowed system may lead to stomach ache.

  • Nausea or Vomiting

The inner ear is responsible for the body’s balance. When scuba diving, the coordination between the eyes, ears and the body is lost.

The eyes perceive a still environment in the boat, while the rest of the body senses the water motions. The conflicting senses may induce nausea and, in some instances, vomiting.

  • Gassiness

Though you may not be gassy while scuba diving, the problem may arise once you are back on the surface. Swallowing air when entering or leaving the ocean may later on cause cramps, abdominal fullness, flatulence, and belching.

What to Do if You Need to Poop While Scuba Diving?

If you get an urge to poop while underwater, the best solution is to restrain yourself. The need may disappear, and you will be able to continue with the exploration.

If the need persists, do not relieve yourself in the waters. Doing so may ruin your diving wear. Instead, alert the team of your exit, and get back to your boat to relieve yourself.

If the urge is urgent and challenging to hold, swim further away from your partners. Relieve yourself at a place where you are sure the water tide is going away from your buddies.

Can You Poop in a Wetsuit?
