Parents always show increased attention to the health of their newborn children, noting all unusual and therefore alarming moments. Especially young mummies and daddies are worried when the lower lip and / or the chin of the newborn are shaking. This incomprehensible symptom seems to be not dangerous, but raises many questions and in order to separate the norm from pathology, it is necessary to understand the causes of this phenomenon.
Why does the lower lip and chin of the newborn tremble?
In the first three months of life, there is a physiological tremor of the lower lip, chin and limbs in the newborn. The reason for this lies in the immaturity of the endocrine and nervous systems of the baby. The adrenal glands can not adequately control the amount of norepinephrine released into the blood in a violent manifestation of emotions, and immature centers in the brain are not yet able to control the movements completely. The combination of these nuances of the child's development leads to the fact that the baby's lip periodically shakes. It is characteristic that in norm the tremor is noted after strong emotional excitement, crying and physical activity.
In which case to sound an alarm, if the lip of a newborn is trembling?
- if the tremor does not pass after reaching the child three months;
- if not only the lip is shaken, but the head as a whole;
- if the tremor was not preceded by crying or an emotional outburst;
- if the tremor is clearly expressed and occurs frequently and without cause.
When identifying the above signs, you should contact the pediatrician for a referral to a pediatric neurologist who will prescribe the necessary diagnosis of the causes and select the treatment.
Causes of lower lip tremors in newborns:
- hypertension of muscles;
- prematurity, because their nervous system is immature by definition, and development within the mother's womb is significantly different from development outside of it;
- stresses experienced by the mother during pregnancy - adrenaline that penetrates the placenta, can provoke
disorders in the development of brain structures; - hypoxia, both during pregnancy and during childbirth, which can be caused by various causes (intrauterine infections, mother's diseases, the threat of miscarriage , polyhydramnios, rapid delivery or vice versa, weak labor activity, etc.).
In most cases, the detected tremor is easily eliminated by simple enough methods: relaxing and restorative massage, baths and swimming, taking vitamins, and physiotherapy.
