Vomiting With Overfeeding-vidown

Health Nearly every newborn will forcefully empty his stomach at one time or another. Babies vomit as a result of any one of a great number of diseases, but more than 95 percent of them vomit because of overdis-tension of their stomachs. Overdistension doesn’t always mean overfeeding. The baby’s stomach can just as easily overdistend with air. Air enters a baby’s stomach whenever she cries, sucks on a pacifier, gulps her milk, or makes an in.plete seal with the breast. If the air isn’t promptly returned to the room via a burp, it warms up from room to body temperature. Being a gas, air expands as it’s warmed, and the little gulps of it grow, distending the baby’s stomach. This is called aerophagia (aero refers to air; phagia means eat). Secondarily, milk can overdistend the baby’s stomach. The average baby from ten days to six months old can hold in her stomach 30 milliliters of milk for every kilogram that she weighs. In other words, a 3-kilogram baby should be able to hold 90 milliliters in her stomach. But what if her stomach already holds 60 milliliters of air? In that case, putting another 90 milliliters of milk in will cause the same overdistension that feeding her 150 milliliters would produce. Whether milk or air, the result is the same. The baby’s stomach muscle gets stretched and stretched, and when it reaches a critical level of tension, it contracts, emptying its contents. If you could be sure how much air was in your baby’s stomach at the start of feeding, you would know how much milk you could safely give without producing overdistension. Regrettably, there’s no way of knowing, and that’s why so many Wealthy, normal babies vomit. What you might do to avoid vomiting is to try burping the baby just before you start to feed her. If she’s a cooperative child, she’ll oblige you by emptying the air from her stomach. If she’s like most hungry babies, she’ll cry until she gets what she wants. And she doesn’t want to get burped. Still, the cause is worthy, and what do you have to lose? Spitting Up and "Cheesing" (Reflux) Regurgitating, spitting up, and cheesing are all terms for the no forceful, partial emptying of the stomach. Sometimes just a trickle of milk flows out of the corner of the sleeping baby’s mouth. Sometimes a burp carries an unexpected payload. Often, little more than chunks of sour, curdled milk ooze out of the baby’s smiling mouth, staining and perfuming the baby’s clothing, the baby, your rug, and you. The "cheese" of one of my children always landed in my shirt pocket, scoring a direct hit into a freshly opened pack of cigarettes. As you might imagine, this put a permanent end to my smoking habit. Like vomiting, spitting can be a sign of any one of a long list of serious diseases, but in the overwhelming majority of cases, babies’ spitting up is caused by reflux (re means backward; flux is flow) from the stomach back to the mouth. The primary culprit is the infant’s immature esophagus. The esophagus is the tube that carries fluids and solids from the mouth to the stomach. A ring of muscle fibers surrounds its end near the stomach. When the baby swallows, the muscle ring or sphincter relaxes, allowing the food to pass through. To keep the food from backing up, the sphincter then contracts, creating a zone of pressure higher than the stomach’s. The difference in pressure keeps the flow of food from the esophagus moving in the direction of the stomach. If the pressure difference is reversed, gastro- (stomach) esophageal reflux (or GER) will occur. About the Author: 相关的主题文章:
