What is the cause of intussusception?

In general, intussusception may be caused by abnormal intestinal peristalsis, the physiological structure of the ileocecal region in infants and young children, rotavirus infection, acute appendicitis, Meckel's diverticulum, among other factors. If discomfort occurs, timely medical attention is recommended. Specific analyses are as follows:

1. Abnormal Intestinal Peristalsis

Discoordination of contraction and relaxation in intestinal smooth muscles, or external stimulation, may cause a segment of the intestine to telescope into an adjacent segment, leading to intussusception. It is advisable to pay attention to dietary adjustments and avoid irritating foods.

2. Physiological Structure of the Ileocecal Region in Infants and Young Children

Due to immature intestinal development in infants and young children, the ileocecal region is prone to inflammation-induced edema and thickening. During peristalsis, this may pull on the intestinal tract and lead to intussusception. Attention should be paid to infant dietary hygiene to prevent intestinal infections.

3. Rotavirus Infection

After exposure to certain substances causing rotavirus infection, damage to the intestinal mucosa may result in cauliflower-like protrusions and localized thickening of the intestinal wall, leading to narrowing of the intestinal lumen and triggering intussusception. This may be accompanied by symptoms such as bloody stools and abdominal pain. Under medical guidance, patients may use medications such as Isatidis Radix Granules, Ribavirin Tablets, and Oseltamivir Phosphate Capsules for treatment.

4. Acute Appendicitis

Acute appendicitis is often associated with bacterial invasion and other causes. Inflammation leads to congestion, edema, and exudation of the intestinal mucosa, disrupting normal intestinal motility and emptying, thereby promoting the formation of intussusception. Symptoms may also include abdominal pain and rectal bleeding. Under medical guidance, medications such as Levofloxacin Tablets, Metronidazole Tablets, and Mesalazine Enteric-coated Tablets may be used for treatment.

5. Meckel's Diverticulum

Meckel's diverticulum is usually caused by developmental abnormalities. Food residues and bacteria can easily accumulate within the diverticulum, leading to inflammation and edema, which may result in symptoms of intussusception, possibly accompanied by abdominal pain and vomiting. Patients are advised to follow medical instructions and use medications such as Amoxicillin Clavulanate Potassium Tablets, Cefuroxime Axetil Tablets, and Metronidazole Tablets to alleviate symptoms.

Maintaining a balanced diet, avoiding irritating foods, and keeping emotionally stable are recommended in daily life to reduce the risk of intussusception.
