Vomiting and Nausea Symptoms

• Nausea is a sensation that almost everyone knows from personal experience. It is a feeling of unease that frequently includes an upset stomach, dizziness, and anxiety. There is often an urge to vomit. You often feel as if this sensation comes from your stomach, but it is mostly controlled by the brain.

• Vomiting, however, frequently improves the sensation of nausea, at least temporarily. Vomiting occurs when the stomach forcefully sends its contents up to and out the mouth. If the nausea is severe, vomiting can continue after all the food and liquid has been sent out. This is called the dry heaves.

• When vomiting leads to dehydration from loss of fluids, you may have increased thirst and dry lips and dry mouth. You may not urinate often. In children, signs of dehydration include dry lips and mouth, sunken eyes, rapid breathing, and dry diapers, indicating the child is not producing urine.
