Vomiting and Nausea Symptoms

• Nausea is a feeling of unease that frequently includes an upset stomach, dizziness, and anxiety. There is often an urge to vomit. This sensation often feels as if it comes from the 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 expels its contents out of the mouth. When vomiting continues after all the food and liquid has been forced out, it is called the dry heaves.
• When vomiting leads to dehydration from loss of fluids, the affected person may have increased thirst, dry lips, and dry mouth. The person may not urinate often or urine will be darker in color. In children, signs of dehydration include dry lips and mouth, sunken eyes, rapid breathing, lethargy, and dry diapers, indicating the child is not producing urine.
