The lower esophageal sphincter LES allows stomach acid and undigested food to travel up your esophagus instead of closing shut.
The sour taste from stomach acid can trigger nausea and even vomiting. Oftentimes, correcting acid reflux requires lifestyle changes. Fried foods, citrus, spicy foods, caffeine, sodas, and alcohol can sometimes weaken the LES.
Other lifestyle changes that can decrease acid reflux episodes include quitting smoking, elevating your head when sleeping, and not lying down after eating. Antacids can also provide immediate acid reflux relief. Have you ever been next in line at some sort of public speaking engagement and felt queasy?

Vomiting for more than a few days, or experiencing other symptoms alongside the vomiting, could mean there is a serious underlying condition and you may need medical assistance. When a vomit is looming, a signal is sent to an area of the brain called the chemoreceptor trigger zone, or CTZ. The CTZ receives this information and determines if the threat warrants vomiting. The CTZ then communicates to other areas of the body to start the domino effect for vomiting.
Before you vomit you may feel nauseous, become pale, have a cold sweat, and have an increased heart rate. Your mouth will also produce extra saliva to protect your teeth from the incoming stomach acid.
As your body prepares to vomit, the major muscles in between the neck and abdomen — the diaphragm, chest wall and the abdominal muscles — all contract at the same time. This puts pressure on the stomach, forcing the contents in the stomach up the throat and through your mouth. Generally, a few contractions occur before vomiting, causing dry heaving. As the contractions continue, the stomach contents are up, up and away!
To protect you from choking, the throat has a flap called the epiglottis which closes to stop any vomit getting into the windpipe and lungs. Vomiting causes the body to lose fluids that contain salts and minerals called electrolytes.
