大多数情况下,有饮食问题的儿童可能没有明确的诊断原因。多达25%的父母报告说他们的孩子在饮食方面有一些问题。这些人通常是蹒跚学步的孩子和年幼的孩子,他们要么很活跃,要么很忙,只是对吃不感兴趣。他们的成长经常沿着成长趋势图表上较低的百分位。有些孩子有对食物质地有要求的问题,只吃特定的食物。这通常是自闭症儿童的一个问题,他们的口腔敏感度更高。患有慢性疾病的儿童,特别是需要长期住院的儿童,往往会出现某种程度的进食问题。这方面的例子包括患有心脏或肾脏问题或其他需要长期住院治疗的疾病的儿童。早产儿对饮食的兴趣降低和饮食不良也存在。
患有神经肌肉疾病的儿童,如果没有协调的吞咽机制,也很难进食。这在患有脑瘫的儿童身上可以看到,脑瘫是一种主要影响肌肉的疾病。有解剖问题影响嘴唇、喉咙后部(上颚)和上呼吸道的儿童也可能发现难以进食。唇腭裂就是这样的例子,但是这些孩子通过手术和支持得到了改善。患有遗传疾病的儿童,例如唐氏综合症,一开始喂养能力很差,在早期需要特殊的帮助和支持。
有饮食问题的孩子需要什么样的评估?
如果你认为你的孩子吃东西很差,并且你很担心,那么向他或她的儿科医生寻求帮助是明智的。值得进一步评价的危险信号如下:
在回顾孩子的发育历史与进行物理、儿科医生的治疗后,可能会更加小心地选择遵循或引导你的孩子的专家,如儿科胃肠病学家、儿童营养师、遗传学专家、小儿耳鼻、喉科专家或发育儿科医生(尤其是发育滞后或孤独症的问题),也可以从儿童语言治疗师寻求帮助。根据这些评估,医生可能会要求进行血液测试,以检查贫血和营养不足,并检查血液电解质状态。医生也可以安排特殊的钡餐x线检查(上消化道)来评估上消化道的解剖结构,并进行吞咽研究来评估吞咽机制。
我们可以做些什么来帮助孩子解决饮食问题?
随着时间的推移,在一些帮助和支持下,大多数有进食问题的孩子都会有所改善。通常,饮食干预和一些增加热量摄入是需要采取的措施。这些方法可以帮助那些生长发育不良的儿童,而这些儿童的生长发育也与口腔摄入不良有关。在儿童中,只有5%到10%的热量摄入是生长所必需的,因此只需要少量增加热量摄入。可以寻求儿科营养师的帮助,食物的选择可以轮换和重复,使其更能吸引孩子吃不同的食物。在这种情况下,孩子们坚持有限的食物选择并不罕见,但他们通常会随着时间的推移而改善。
那些有持续喂养问题风险的儿童,特别是早产儿、自闭症儿童、神经或解剖问题儿童以及遗传疾病儿童,需要更全面的方法。职业和语言治疗师的帮助也可以招募。这些孩子经常按照自己的节奏进步,强迫他们提高摄入量可能会适得其反。有时,同时存在胃食管性反流的儿童在选择适当的反流治疗后可能做得更好。一些孩子在服用了像赛庚啶这样的药物后,食欲会有所改善。
有一些儿童和蹒跚学步的孩子有明显的口腔厌恶,需要进一步的干预和支持。将喂食管通过鼻孔插入胃中,或者直接进入胃中,将有助于减轻孩子和父母的压力,并有助于提供额外的热量来维持生长和发育。管子的目的不是提供所有的热量需求,而是作为一个管道,提供补充营养。尽管有试管,还是应该鼓励孩子们用嘴吃东西。
此外,将有严重口腔厌恶和喂养问题的儿童纳入一个既定的喂养计划可能更有助于帮助儿童提高口腔喂养技能。该项目通常包括儿童心理学家、儿童营养师、职业和语言治疗师。在这样的项目中,对病人的需要进行广泛的评估,并为病人制定单独的项目。治疗包括与父母合作,帮助提高孩子的口腔适应咀嚼吞咽技能。这些疗法需要时间才可能发挥作用,而且这些项目需要长期与其他专家密切合作。
MOST OFTEN, CHILDREN with problems related to eating may not have a clear diagnostic reason. Up to 25 percent of parents report that their children have some problems with eating. These are often toddlers and young children, who are active or otherwise busy and just not interested in eating. They grow and often maintain their growth along the lower percentiles on the growth chart. Some of these children have food texture issues and choose to only eat certain foods. This is often a problem in children with autism, who have heightened oral sensitivities. Children with chronic medical conditions, especially those requiring prolonged hospitalization, often develop some degree of feeding issues. Examples of this include children with heart or kidney problems or other disorders that require prolonged inpatient hospital admission. Decreased interest in eating and poor eating are also seen in premature babies.
Children with neuromuscular disorders who do not have a coordinated swallowing mechanism also struggle to eat. This is seen in children with cerebral palsy, a disease that predominantly affect muscles. Children with anatomical problems affecting the lips and back of their throat (palate) and upper airway may also find it difficult to eat. Cleft lip and palate are examples of this, but these children improve with surgery and support. Children with genetic disorders, for example Down syndrome, are poor feeders in the beginning and will require special help and support in the early years.
What kind of evaluations would a child with a feeding problem require?
If you think that your child is a poor eater and you’re concerned, it’s prudent to seek help from his or her pediatrician. Red flags that warrant further evaluation are as follows:
After reviewing your child’s history and conducting a physical, the pediatrician may choose to follow your child more carefully or refer your child to a specialist, such as a pediatric gastroenterologist, pediatric dietitian, genetics specialist, pediatric ear nose and throat specialist or developmental pediatrician (especially if developmental miles stones are lagging or if there are concerns of autism), and may also seek input from a pediatric speech therapist. Based on these assessments, the doctor may order a blood test to look for anemia and nutritional deficiencies and check blood electrolyte status. The doctor may also order special barium X-ray tests (upper GI) to evaluate the anatomy of the upper gastrointestinal tract, plus a swallow study to assess the swallowing mechanism.
What can be done to help children with feeding problems?
Most children with feeding problems improve over time and with some help and support. Often, dietetic interventions with some increase in caloric intake is all that is required. This approach helps those children who also have poor growth associated with poor oral intake. In children, only 5 to 10 percent of caloric intake is required for growth and therefore only requires a small increase in caloric intake. The help of a pediatric dietitian may be sought, and the food choices may be rotated and repeated to make it more appealing for the child to eat different foods. It’s not uncommon for children to stick with a limited choice of foods in this situation, but they usually improve with time.
Those children who are at risk for persistent feeding problems, especially premature babies, children with autism and kids with neurological or anatomical problems, as well as genetic disorders, require a more comprehensive approach. The help of occupational and speech therapists may also be enlisted. These children often improve at their own pace, and pushing them to improve intake can become counterproductive. Occasionally, children with coexistent gastroesophageal reflux may do better after optimal management of reflux. Some children may show improvement after taking medications like cyproheptadine that help boost appetite.
There are some children and toddlers who have significant oral aversions and require further interventions and support. Placement of a feeding tubethrough the nostril into the stomach, or directly into the stomach, will help ease pressure off the child and the parents, plus help provide extra calories to maintain growth and development. The intention of the tube is not to provide the entire caloric need but to serve as a conduit to provide supplementary nutrition. Children should still be encouraged to take food by mouth, despite the tube.
Occasionally, enrolling children with significant oral aversions and feeding problems in an established feeding program may be required to help a child work on his or her oral feeding skills. The program often involves a child psychologist, a pediatric dietitian and occupational and speech therapists. The needs of the patient is evaluated extensively in such programs and an individual program is charted for the patient. Therapy involves working with the parents to help advance their child’s oral intake skills. These therapies take time to work, and the programs often work in close coordination with other specialists.
