Arched Back Crying Baby - What Does it Mean?
Crying is a completely healthy and normal thing that all newborn babies do (to varying degrees). Particularly in the first several weeks after birth, crying is a baby's only effective method of verbal communication. As babies grow they quickly develop other verbal and non-verbal communication tools, but early only crying is the only effective tool in the infants have to talk to their parents.
Not all infant crying is the same. Infants deploy different types and levels of crying to communicate different things. Some crying is meant to signal that the baby is hungry. Other types of crying is meant to signal pain or discomfort. Parents usually pick up on these subtle crying differences very quickly.
New babies will often cry because they are in discomfort or mild pain. Newborns have gas and things that bother them so pain crying is nothing to worry about. However, there is one particular type of "pain crying" that is cause for concern: arched back crying. If a baby appears to be arching its back while crying intensely this is considered abnormal and possibly concerning. Back arching is a common reflex that babies exhibit when they suffer from very acute or strong pain. So if a baby is flexing their back up when they cry it usually means they are feeling more than just the normal baby pains. The other reason infant back arching (with or without crying) can be cause for concern is that arching the back is also an early symptom of spastic cerebral palsy.Possible Causes of Arched Back Crying
Anything that causes a baby to experience significant pain or discomfort can trigger arched back crying. Here is a list of some potential triggers. Keep in mind that the less serious causes are more likely.
- Colic: colic is a very common problem for many newborn babies. Colic is sort of a broad term used to describe gastrointestinal discomforts in infants. No one really knows exactly why or how colic occurs, but we do know that it has to do with the fact that infants have immature digestive systems and tend to be overly sensitive. Individual cases of colic can range from mild to very severe. Babies were severe colic can exhibit very intense pain on a regular basis. Colic usually goes away as the baby develops. Colic is the likely cause for any arched back crying.
- Infant Acid Reflux: gastroesophageal reflux (commonly called "acid reflux") is a very common problem for newborn babies. Just like acid reflux in adults, infant acid reflux happens when food (for infants breast milk or formula) in the stomach gets pushed back upwards into the throat and esophagus. The reflex that pushes the food back up is uncomfortable itself and the refluxed food or milk is mixed with stomach acid so it burns the inside of the throat. In adults, acid reflux is usually just a minor discomfort, not something particularly painful. In newborns, however, infant acid reflux can be extremely uncomfortable and even painful. So infant acid reflux is a very likely cause of arched back crying. Especially when the back arching seems to occur after feeding.
- Nerve Damage: during a long or difficult vaginal delivery, babies often suffer damage to their delicate nerves. The nerves in the baby's shoulder are particularly vulnerable during vaginal delivery. When nerve damage during delivery is very significant, it can result in permanent injuries such as Erb's Palsy. Minor nerve damage or pinched nerves suffered during vaginal delivery can trigger acute pain along the baby's neck and back. This shooting pain can be a potential trigger for back arching and pain crying.
- Jaundice/Kernicterus: infant jaundice is a very common condition that most newborns experience to some degree. It is caused by excess levels of bilirubin (a waste product of red blood cell break down) in the baby's bloodstream. Jaundice itself is not painful, however, if not managed jaundice can progress to dangerous levels. Eventually, severe jaundice can lead to kernicterus, a rare type of brain damage caused by excess bilirubin. When jaundice starts to progress to this threatening stage baby's reportedly experience intense pain along their spine. If a baby has severe jaundice, arched back crying is often viewed as an early clinical symptom of kernicterus.
- Cerebral Palsy: cerebral palsy is a movement disorder caused by damage to the developing brain of a baby or fetus. The injury impairs the brain's ability to control and coordinate muscle movements in the body through impulse signals. There are several different types of cerebral palsy. The predominant type of cerebral palsy is spastic CP which is characterized by involuntary muscle contractions and rigidity. Back arching in newborn babies is often one of the earliest signs of the involuntary muscle contractions that plague children with spastic CP.
