What is nausea?

Nausea is simply awful. It’s a stomachache that can cause a loss of appetite, vomiting, and other symptoms as well. Often, nausea brings the overwhelming urge to vomit which can be accompanied by a lot of stomach discomfort.

One moment you are okay and going about your business, and in the next moment your stomach is churning, and your mouth is producing excess saliva.

Your next course of action is to frantically search for a bathroom to empty the contents of your stomach.

We’ve all been there. Not fun.

This condition can be occasional and short-term, or it can be a chronic condition that lasts longer. If you suffer from nausea a few times a week or more often, it is probably greatly affecting your quality of life and general health.

When you are dealing with persistent nausea, it’s nearly impossible to be productive. You may also start to deal with other health conditions such as dehydration or malnutrition if you vomit often and cannot hold down food or water.

What causes occasional nausea?

Short-term nausea is a protective mechanism of the body to get rid of toxins or dangerous substances in the body.

One example of this is food poisoning. Just about everyone has had experience with eating undercooked or contaminated food. You may vow to never eat that dish ever again thanks to your uncomfortable experience of hanging out next to the toilet all night afterward. (I’m still not a fan of rotisserie chicken…)

In this case, nausea is a response in your body that helps you to quickly get rid of the food before it causes serious illness. Fortunately, food poisoning nausea doesn’t usually last very long.
