Why do strong emotions sometimes cause people to become physically sick and throw up?
Q: Okay here's some examples. When people are nervous. When people are in pain. When people are emotionally disgusted, etc etc. My one friend vomited when he found out that his girlfriend had been raped by a guy before they went out. I always thought that to be physically sick you needed to have a virus or be grossed out. What happens when people throw up from emotions? Why?
A: it is called fight or flight...your body has no other way to react...The Fight or Flight ResponseThe choices people make while they are experiencing significant trauma, and afterwards, aren't always consciously crafted decisions. They generally fit into three typical categories of self-preservation techniques that humans employ whether they think about it or not, Dr. Moffic said, and post-traumatic stress disorder is often the result when those techniques go far beyond simple coping mechanisms. "Probably the best way to think about that is, when we're exposed to a trauma - whether it's a little one like on Halloween or a big one like a serious accident - our more primitive self-help responses go into motion," said Dr. Moffic. "This is generally called 'fight or flight.' If we're faced with a trauma, our initial, almost unconscious reaction, is to flee or fight. Or, if we can't do either, we may just sit and withdraw. Those kinds of responses have been known for thousands of years, since the cavemen. That's how humans respond to trauma. "When the trauma is really severe or lasts for a long time, that kind of response goes awry in that it doesn't go away. You're always in a fight-or-flight or withdrawal mode to some degree. Instead of that system going off it's turned on to some degree all the time and that tells us what kind of symptoms we're going to see. "For instance, if you're the kind of person who has responded to trauma by fighting, you're going to be hyper-aroused to one degree or another all the time. Hyper-arousal is one kind of symptom. You could be anxious all the time, you could have trouble sleeping, or you could feel agitated, or startle easily, or be irritable. All those things are a reflection of being over-aroused. You're almost in your fight mode, really ready to fight, all the time. "Second, there's the flight response. If that's been over-stimulated or doesn't go away, what happens when 'flight' goes awry? Your symptoms could include being reserved, quiet, preoccupied, very fearful all the time, or do what we call 'dissociate', which is blanking out for a while, forgetting what you're doing That's what happens if the flight response goes awry." read more here:http://healthlink.mcw.edu/article/1031002705.html

Why do strong emotions some times cause people to become physically sick and throw up?
Q: Okay here's some examples. When people are nervous. When people are in pain. When people are emotionally disgusted, etc etc. My one friend vomited when he found out that his girlfriend had been raped by a guy before they went out. I always thought that to be physically sick you needed to have a virus or be grossed out. What happens when people throw up from emotions? Why?Oh and I heard also that too much stress can cause people to vomit often. How?
A: Strong emotional experiences can overstimulate the sympathetic nervous system and wreak all kinds of havoc physically. Pupil dilation, butterflies in the stomach, vomiting, relaxed bladder (wetting yourself), dry mouth, increased heart rate and respiration, vasoconstriction to stomach and skin (feelings of "goose flesh"), vasodilation of blood vessels. This is commonly called the "fight or flight" reaction. For short periods of time, the body can handle the changes. During prolonged periods of stress, the body startsn to break down. Ulcers, high blood pressure, heart disease, irritable bowel syndrome, colitis, etc. can develop due to extreme sympathetic arousal.
