Quick Answer: Why do I feel sick after diving?

Can diving make you sick?

Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body’s tissues.

How long does decompression sickness last?

After several days of diving, a period of 12 to 24 hours (for example, 15 hours) at the surface is commonly recommended before flying or going to a higher altitude. People who have completely recovered from mild decompression sickness should refrain from diving for at least 2 weeks.

How do you treat diver sickness?

The treatment of DCS is with 100% oxygen, followed by recompression in a hyperbaric chamber. [8] In most cases, this will prevent long-term effects. However, permanent injury from DCS is possible. To prevent the excess formation of bubbles leading to decompression sickness, divers limit their ascent rate.

Is it normal to throw up after scuba diving?

Persistent vertigo and vomiting after surfacing from a dive can be any number of things involving the brain or ear such as inner-ear decompression sickness (DCS), inner-ear barotrauma or stroke. The time of symptom onset after the dive increases the probability that it was caused by the dive.

What do you do if you feel sick after scuba diving?

If you are experiencing vertigo underwater, try closing your eyes to steady the spinning. You could also hold onto your buddy or a descent line. If you are still feeling sick after scuba diving, then lay down and rest for a while.

Why do you feel tired after scuba diving?

If you find yourself inexplicably fatigued, or sleepy after diving then it can be due to ‘decompression stress’. … Decompression stress is theorized to be a physiological effect that stems from micro-bubbles that can form in the blood and tissues as a result of sub-optimal dive behaviours.

Why do I get headaches after diving?

The carbon dioxide headache, one of the most common for divers, is caused by an increase in the body’s carbon dioxide level, which stimulates receptors in the brain’s blood vessels. An increase in the brain’s blood flow to these receptors leads to headaches.

What is diving sickness?

Decompression sickness, also called generalized barotrauma or the bends, refers to injuries caused by a rapid decrease in the pressure that surrounds you, of either air or water. It occurs most commonly in scuba or deep-sea divers, although it also can occur during high-altitude or unpressurized air travel.

What is depth poisoning?

Nitrogen narcosis, also known as depth intoxication or rapture of the deep, is a change in consciousness and neuromuscular function caused by breathing compressed inert gas.

Will decompression sickness go away?

In some cases, symptoms may remain mild or even go away by themselves. Often, however, they strengthen in severity until you must seek medical attention, and they may have longer-term repercussions.
