The causes of pediatric constipation 1, diet and lifestyle habits inappropriate diet is too little, too fine, lack of vitamins, insufficient water, etc. can induce constipation. Eating less, insufficient calories in food, not easy to induce gastrointestinal response, colon peristalsis slowed down, no stool, while long-term dietary deficiencies form malnutrition, then the abdominal muscle and intestinal muscle thin, low tension, weakened propulsion, forming a vicious circle, constipation aggravated. High-fiber diet is not easy to constipation because the fiber polysaccharide in food can not be digested, part of which can be decomposed in the intestine by the fermentation of cells, the end product is short-chain fatty acids, ammonia, CO2 and methane, can stimulate the colon to produce peristaltic enhancement, and undigested fiber can increase the stool volume, retain water, soft stool, shorten the intestinal running time, reduce the pressure in the colon. The mechanism of the role of fiber in the development of constipation is not well understood, and it has also been reported that constipation occurs independently of fiber. If the food contains more protein and less carbohydrate, there are more bacteria in the intestine to break down protein than fermenting bacteria, and the intestinal contents are less fermented, so the stool is alkaline, dry and less frequent. If the fat and carbohydrate content is increased, the stools are more frequent and soft. After consuming a large amount of calcified casein, the stool is easily dry and constipated. Older children have an irregular life, lacking the habit of defecation, and have not established a good conditioned reflex to defecate, often not defecating for several days. Commonly used laxatives or enemas, lack of physical exercise or chronic diseases, especially malnutrition and rickets can make intestinal dysfunction and constipation. 2, congenital megacolon Congenital intestinal ganglion cell deficiency 3, idiopathic megacolon A psychological, functional constipation caused by peristaltic dysfunction of the colon. Children often inhibit defecation due to playfulness, or parents are too hasty in training defecation and take coercive measures, which makes children nervous when defecating and affects the establishment of normal defecation reflex. The onset is mostly after 2 years of age. A few have abdominal pain or fecal incontinence, and the rectum and colon filled with feces can be palpated in the abdomen. 4, local organic lesions congenital anal stenosis, rectal perineal fistula or congenital anorectal malformation after surgery can lead to constipation. Those who suffer from anal fissure or other painful anal canal and rectal diseases can resist defecation for a long time, which is a more common cause of constipation in children. 5, the sigmoid colon is too long Conservative treatment first, most of the light can be cured. If it is ineffective, rectosigmoidectomy is performed, and the long-term results are more satisfactory after surgery. 6, endocrine disorders hypothyroidism, in infancy, there is a loss of appetite, feeding difficulties, hypotonia, abdominal distension and constipation. In hyperthyroidism, blood calcium increases, neuromuscular stress decreases, intestinal peristalsis weakens, muscle power is low, appetite is poor, weight does not increase and constipation. This kind of constipation is a local manifestation of systemic diseases. 7, neurological diseases Cerebral hypoplasia, cerebral palsy or microcephaly can interrupt the defecation reflex or inhibit the parasympathetic nerve, with varying degrees of constipation. Treatment of pediatric constipation 1, adjust the diet There should be a suitable recipe in infancy, such as constipation, you can add juice or honey. Manual feeding infant constipation, should reduce the amount of cow’s milk or increase the amount of sugar in the cow’s milk 8%-10%, and add juice. The diet of older children should contain some coarse grains made of food. 2, training defecation habits defecation is a reflex action. Children can be trained to develop the habit of defecation in accordance with the early morning to sit on the potty, if you can not defecate faster, do not chastise, and do not squat for a long time, so as not to cause rectal prolapse or defecation inhibition. 3, medication laxatives can be taken for a short period of time, occasionally a small piece of soap bar (after wetting with water) inserted into the anus, or wear gloves after hand picking stool. 4.Chinese medicine and acupuncture Chinese medicine believes that habitual constipation is caused by the deficiency of fluid and intestinal dryness, and the treatment is to nourish Yin and moisten the intestines. 5, enema therapy for long-term chronic constipation can be used to retain the oil enema or saline enema. 6.Surgical therapy For the above-mentioned treatment is ineffective in children should consider surgery.
