In daily life, we can often see such scenes, some children playing and suddenly will say their stomach pain, some pain with a hand over the stomach, or squatting on the ground crying stomach pain, and some even pale. This is when parents usually rush to take their children to the hospital, only to have them get better after a while. This tossing and turning of parents wastes time and delays work, so it is important to learn to distinguish whether a child’s abdominal pain is functional or organic lesions. Functional abdominal pain generally requires no special treatment and can disappear on its own, while organic abdominal pain must be differentially diagnosed and treated by a professional physician. From the medical professional point of view, the causes of abdominal pain are actually quite complicated, if combined with the abdominal pain I usually encounter in my clinical work, I would like to elaborate from the following aspects to facilitate your understanding: 1. The nature of abdominal pain in general: 1) the characteristics of abdominal pain of a medical nature: 1) the abdominal pain site is relatively diffuse, and the positioning is not very accurate: the child will say that it hurts here and there for a while, and even if it refers to a place that hurts (2) they like to press and feel that the pain can be relieved by rubbing; (3) they can be relieved by themselves, and there is no sign in the abdomen after relieving, that is, after the child says that the stomach does not hurt anymore, you can press on the abdomen of the child and it does not hurt, like nothing happened. (4) Most of them are not accompanied by fever, and even if there is fever, the fever is followed by abdominal pain, and the abdominal pain improves when the body temperature drops; (5) In general, eating does not aggravate the abdominal pain; 2) The characteristics of abdominal pain of surgical nature: (1) the pain is generally severe and unbearable for the child, and it is not easy to relieve the pain naturally, and there is a trend of gradual aggravation; (2) the pain site is relatively fixed, for example, appendicitis is more familiar to everyone, although the clinical (3) often accompanied by its symptoms, such as fever (abdominal pain and then fever), abdominal distension, frequent vomiting, vomit with bile, etc. (4) sometimes can be found in the abdomen mass, or muscle tension, rebound pain, etc.; Second, the common causes of different ages 1, neonatal period: the child abdominal pain will suddenly cry, can not be soothed, if accompanied by If it is accompanied by abdominal distension, vomiting of bile-like material and poor response, it should be alerted to intestinal developmental malformation or necrotizing small bowel colitis (NEC). 2. Infancy and early childhood: paroxysmal violent crying and fussing due to intestinal spasm is more common, and abdominal pain can occur repeatedly if the child eats milk as usual during the interval without abnormal performance; however, if the child has an inguinal hernia, attention should be paid to check whether the hernia can be retracted, and if it cannot be retracted, the crying and fussing will be aggravated when the child touches the hernia. If the child is crying, vomiting frequently, bloating, not passing stool or even blood in stool, the child should be alerted to the possibility of intussusception; abdominal pain and vomiting and diarrhea caused by autumn diarrhea or pediatric enteritis will improve naturally as the disease gets better. 3, preschool and school age: poor defecation can cause intestinal spasm, manifested as a few days without defecation, sudden pain in the left lower abdomen or left part of the navel, pressure pain increased, the left lower abdomen with fecal mass, the pain disappears after laxation, pressure on the abdomen also no pain; improper diet, or after cold can appear vomiting, discomfort and pain in the upper middle abdomen, vomiting is obvious after eating, vomiting abdominal pain temporarily relieved, vomiting abdominal pain is obvious when temporarily Most of the vomiting and abdominal pain will disappear on their own; the vomiting and abdominal pain caused by gastroenteritis are due to gastrointestinal inflammation, and as long as the gastrointestinal inflammation disappears, the natural abdominal pain will be relieved. Rarely, abdominal epilepsy can have seizure abdominal pain performance, and the diagnosis can be confirmed by perfecting EEG examination, and the abdominal pain disappears after antiepileptic treatment. 4, adolescence: chronic gastritis, peptic ulcer disease can cause chronic abdominal pain, obvious under the mid-upper abdominal saber, obvious after eating, or pain when hungry, often accompanied by belching, acid reflux, abdominal distension performance, may have subsaber pressure pain, HP antibody test or C14 breath test positive, help determine the disease, gastroscopy can confirm the diagnosis, treatment of the primary disease, abdominal pain can be relieved; acute appendicitis typically manifests as metastatic right lower The typical manifestation of acute appendicitis is metastatic right lower abdominal pain, accompanied by fixed pressure pain in the right lower abdomen, fever, vomiting, diarrhea, etc. Clinical manifestations of peritonitis may occur after appendiceal perforation, which requires timely disposal by a surgeon. Adolescent females often have manifestations of vegetative dysfunction, and may have symptoms such as chest tightness, abdominal pain, dizziness, etc. Auxiliary examinations often have no positive findings, and most of them do not affect study and life, and can be seen in the adolescent psychology clinic. The above is my summary of some relevant knowledge about abdominal pain in childhood, which is not comprehensive, but it is enough for families to know this information. I hope my scientific article is helpful to you.
