Holly from Indiana speaks for about 90 million fellow sufferers of this problem. Here's the small and large story about the intestines: Serotonin is the natural chemical in the body that antidepressants affect. Though 5 percent of your body's serotonin is in your brain, 95 percent is in your intestines. "You have a second brain down there," Dr. Oz says. "There are 100 million nerves in that intestine tract. That's the same amount of nerves as you have in your spine."
If your intestines become confused, Dr. Oz says, one effect could be diarrhea, bloating and discomfort from inflammatory bowel disease, or IBS, a very common problem. If you have this problem for more than a day or so, "take chicken soup with some rice because it will help you reabsorb sugar and salt." If you get diarrhea chronically, Dr. Oz says the cause may be food allergies. Some common food allergies include milk products and wheat.
According to Dr. Oz, diarrhea is not necessarily a bad thing. Sometimes, it's just your body's way of protecting itself. "The immune system in your intestines is a very intricate one and it knows when food is not right for you," he says. "So it will tell your body, 'You know what? Get rid of that. We don't want this in us!'"
