In life, children inevitably get tummy aches. What is the cause of tummy ache in children? Knowing the possible causes of your child’s tummy ache can help you take timely measures to diagnose and treat it. 1. Intestinal cramps: This is the most likely cause of tummy pain in children. In hospital pediatric surgery clinics, the majority of children’s stomach pains are caused by pediatric intestinal spasms (intestinal cramps). The main causes of intestinal cramps are growing pains or eating improperly. This is when the child does not have certain pressure points, can eat and drink, and is in pretty good spirits. 2, ascariasis: after the larvae of the worms develop into adult worms in the small intestine, they have toxic effects and mechanical stimulation on the small intestine, causing abdominal pain, diarrhea, indigestion and other symptoms to occur. When the number of adult worms is as many as tens or hundreds, the worms can twist and form a group with each other, causing intestinal obstruction. And roundworms have the habit of drilling, and often burrow into the appendix and bile ducts to cause appendicitis and biliary ascariasis, resulting in abdominal pain. When the environment changes or the child has fever, diarrhea, hunger and eating irritating food, the child suddenly has abdominal pain, crying, rolling, bending, cold sweat, pale face, and the abdominal pain is most serious around the navel. Sometimes the abdominal pain can relieve itself or even disappear. Each pain attack for a few minutes, this pain may come on every other day, but also may be several times a day. 3, enteritis: mainly around the umbilicus as the center of the entire lower abdominal pain, accompanied by vomiting, diarrhea, the stomach feel soft, no fixed pressure points. Enteritis is usually caused by eating an unclean diet. The daily life can pay attention to dietary hygiene. 4. acute appendicitis: mainly pain in the right lower abdomen. 2 or 3 year old children have stomach pain and have obvious bloating, accompanied by vomiting, pressure pain all over the abdomen, not allowed to touch, may have a fever of 38 degrees more. 2 or 3 year old children should pay more attention because it is easy to cause perforation and become peritonitis. 10 year old children with appendicitis start with pain in the upper abdomen and after a few hours move to pain in the right lower abdomen, some The child is accompanied by nausea and vomiting, and there are very obvious pressure points in the right lower abdomen that are not allowed to be touched. 5. Ingrown hernia: The abdominal pressure increases due to crying, coughing, laughing, sneezing, and exertion (such as when relieving stool), which causes the intestines to enter the groin or scrotum, thus causing abdominal pain. The child may have paroxysmal crying, abdominal pain, abdominal distention and vomiting, and a swelling in the inner groin when standing or straining to defecate, or an enlarged scrotum on one side only. 6. Acute mesenteric lymphadenitis: bacteria enter the celiac duct through the ruptured intestinal mucosa of the gastrointestinal tract, causing inflammatory enlargement of the mesenteric lymph nodes; clinical symptoms such as fever, abdominal pain, nausea, vomiting and diarrhea appear due to stimulation by inflammatory exudate. Often, fever and abdominal pain follow. The site of abdominal pain may be diffuse or vary depending on the location of the inflamed lymph nodes, but is most common in the right lower abdomen. The site of abdominal pain is variable, as is the intensity of abdominal pain. It occurs mostly in children with allergies. It is often associated with the consumption of allergenic foods such as fish, shrimp, eggs, etc. The pain around the umbilicus often occurs along with itchy rash on the skin, accompanied by vomiting and diarrhea.
