Experts agree that almost no one is immune from motion sickness. Given a strong enough stimulus , anyone with a normal sense of balance will succumb. Some people are susceptible to certain types of motion only or under special circumstances only. Individuals who may experience no discomfort at all riding in a car or plane, might fall victim to seasickness because of the ship's combined motions of pitching from back to front and rolling from side to side. Others can become queasy on a carnival ride or even in a movie chase scene. The reasons for the body's unpleasant reaction to movement are really not known. Theories focus on the delicate balance system in the inner ear. A mismatch between the balance the ear "feels" through the semicircular canals and the balance that the eye "sees" can cause the ear to send signals to a part of the brain known as the vomiting center.

While I admittedly do not have a psychology background, I definitely related to the symptoms she described and it made me wonder. I thought about everything parents dealing with a child that has IBD go through, as well as what we went through with our child. In my case, I had just had my twins six weeks earlier and the hormones were nuts! One of my twins never slept, was in pain constantly from GERD and had issues with her airway that we later determined was from severe asthma. Watching your child frequently struggle to breathe or scream in pain while you are helpless to do anything is heart-wrenching, to say the least. When my daughter was six-weeks old she had an apnea related to her GERD that was later determined to be an ALTE, apparent life-threatening event. She stopped breathi...
