Long-term abdominal pain before bowel movements, relieved after defecation

In general, persistent abdominal pain before bowel movements that relieves afterward may be caused by poor eating habits, gastrointestinal dysfunction, viral gastroenteritis, or other factors. Patients can receive symptomatic treatment based on the specific cause. The detailed analysis is as follows:

1. Poor Eating Habits

Frequently consuming foods low in dietary fiber may slow gastrointestinal motility, causing food to remain in the intestines and resulting in abdominal pain before defecation, which resolves afterward. It is recommended to adjust the diet by increasing intake of fiber-rich foods.

2. Gastrointestinal Dysfunction

Regularly skipping breakfast or having irregular eating patterns may lead to abnormal gastrointestinal function and cause abdominal pain before bowel movements. It is recommended that patients, under medical guidance, take medications such as mebeverine hydrochloride tablets or Bifidobacterium live capsules, while also maintaining healthy eating habits.

3. Viral Gastroenteritis

Lack of physical activity may reduce immunity, leading to intestinal viral infection and inflammation, causing symptoms such as constipation and abdominal pain. It is recommended that patients, under medical supervision, use antiviral medications such as acyclovir capsules or oseltamivir phosphate capsules, along with appropriate exercise.

Besides the above three causes, similar symptoms may also result from other conditions such as bacterial enteritis, intestinal obstruction, or colorectal cancer. Therefore, patients are advised to seek timely medical evaluation and treatment.
