What causes a slight pain in the lower right abdomen?

Generally, mild pain in the lower right abdomen may be caused by factors such as poor diet, vigorous exercise, appendicitis, ureteral stones, Crohn's disease, and others. If discomfort occurs, it is recommended to seek medical attention promptly. Detailed explanations are as follows:

1. Poor Diet

Consuming excessive amounts of cold, spicy, or greasy foods in one sitting, eating too quickly, or overeating may cause gastrointestinal spasms, resulting in pain in the lower right abdomen. It is recommended to adjust dietary habits, avoid irritant foods, eat regularly, and chew food slowly.

2. Vigorous Exercise

Sudden vigorous exercise, such as fast running or rope jumping, may cause intestinal motility disorders and pulling of the intestinal mesentery, leading to pain in the lower right abdomen. Adequate warm-up before exercise, gradual increase in intensity, and immediate cessation of activity if pain occurs are recommended. Rest and gentle abdominal massage may help alleviate symptoms.

3. Appendicitis

Appendicitis typically occurs due to blockage of the appendix lumen, followed by bacterial invasion, causing inflammatory reactions in the appendix. Inflammation may irritate surrounding tissues, resulting in the aforementioned symptoms. It may also be accompanied by nausea and vomiting. Treatment may include medications such as amoxicillin capsules, metronidazole tablets, or cefixime dispersible tablets, as directed by a physician.

4. Ureteral Stones

When certain components in urine, such as calcium, oxalate, or uric acid, reach high concentrations, they may crystallize and gradually aggregate into stones. When stones move within the right ureter, they may irritate the ureteral mucosa, causing ureteral spasms and resulting in severe pain in the lower right abdomen. Symptoms may also include frequent urination and urgency. Patients should follow medical advice to use medications such as Shenshitong granules, lithiasis granules, or tamsulosin hydrochloride sustained-release capsules for treatment.

5. Crohn's Disease

Crohn's disease may be associated with factors such as genetics, environment, and immune response. The disease primarily affects the terminal ileum and adjacent colon, causing pathological changes such as ulcers, inflammation, and granulomas in the intestinal mucosa, which may lead to pain in the lower right abdomen. It may also be accompanied by symptoms such as fever and anemia. Symptomatic relief may be achieved with medications such as sulfasalazine enteric-coated tablets, mesalazine enteric-coated tablets, or prednisone tablets, as directed by a physician.

In daily life, maintaining regular eating habits, avoiding overeating and irritant foods, practicing good menstrual and sexual hygiene (especially for women), ensuring adequate rest and sleep, and enhancing physical immunity are recommended.
