Baby snoring has become one of the common diseases in infants and children. Snoring in infants is mostly physiological, which is caused by narrow nasal passage and more secretions that obstruct airflow. As the baby grows older, it will gradually improve after three or four months of age. As the baby grows older, if the snoring still occurs or becomes more serious, the family should pay attention to it. Pathological snoring is commonly associated with acute upper respiratory tract infection, tonsillar hypertrophy, nasopharyngeal proliferative gland (adenoid) hypertrophy, obese babies, small chin disorder and structural abnormalities. The tonsillar hypertrophy accounts for 70% to 80% of the children who snore clinically, especially those over 2 years old. When snoring symptoms appear, parents should be alert to whether the tonsils are hypertrophic. Dangerous signs of tonsillar hypertrophy 1. snoring Snoring is a major symptom of tonsillar hypertrophy, which is caused by the obstruction of the airway by the hypertrophic tonsils, and can develop into sleep-disordered apnea in severe cases, resulting in a state of oxygen deprivation at night. Long-term hypoxia prevents children from getting a good night’s rest, being bed-ridden in the morning, fatigued during the day, grumpy and easily irritable. In addition, children with frequent snoring are four times more likely to develop ADHD than ordinary children. These children often show inattentiveness in class and hyperactivity. 2. Nocturnal enuresis American ear, nose and throat specialists have found that children with enlarged tonsils often experience bedwetting at night. This may be because tonsil hypertrophy makes the child’s breathing irregular at night, sleep apnea, the brain is in a state of oxygen deprivation, unable to control the bladder constriction muscle and cause urination awareness disorder. 3, obesity Obese babies are usually heavy phlegm, easy to cough phlegm, coupled with hypertrophic tonsils and neck and chest thick fat extrusion of the airway, increasing the resistance of the airway, seriously affecting the quality of sleep at night, thus endangering the physical and mental health of the baby. At the same time, obese babies are more lazy, depressed during the day, do not like to exercise, forming a vicious circle, so that the child’s weight continues to increase. 4, repeated upper respiratory tract infections The baby with enlarged tonsils is prone to repeated acute upper respiratory tract infections, such as acute purulent tonsillitis, acute otitis media, rhinitis, sinusitis, bronchitis, and the child often has throat discomfort, voice change, speech with occlusive nasal sound, coughing and spitting, shortness of breath, low fever and other symptoms. 5, adenoid face Due to long-term open-mouth breathing, airflow impacting the hard palate, making it deformed and high arched, affecting facial bone development, narrow maxilla, high arched hard palate becomes narrow, teeth protrusion, irregular teeth, poor bite, lower jaw sagging, upper lip short thick upward, lower lip hanging, outer canthus down, nasolabial fissure shallow flat. In addition, the baby’s spirit is depressed, the facial expression is dull and dull, which is the “adenoid face”. 6, developmental backwardness, intellectual hindrance Because children need a lot of oxygen for growth and development, long-term hypoxia, which directly leads to insufficient oxygen supply for brain development, resulting in reduced secretion of growth-promoting hormone. The children show poor nutritional development, lagging height, chicken breast, anemia, thinness, indigestion, weakness, headache, dizziness, inattention, slow reaction, boredom, easy to be frightened, irritability, and grinding teeth in sleep at night.
