What are the causes of intermittent dull pain in the right abdomen?

Generally, intermittent dull pain in the right abdomen may be caused by dietary factors, exercise factors, acute appendicitis, cholecystitis, right ureteral stones, and other reasons. It is recommended to seek medical attention promptly and undergo treatment under a doctor's guidance. Detailed analysis is as follows:

1. Dietary Factors

Irregular eating habits and overeating can lead to gastrointestinal dysfunction, potentially causing intermittent dull pain in the right abdomen. It is important to maintain regular eating habits, consume meals at regular intervals in appropriate quantities, and avoid eating irritating foods.

2. Exercise Factors

During exercise, blood is redistributed throughout the body, resulting in relatively reduced blood supply to the gastrointestinal tract. The intestinal smooth muscles may spasm due to ischemia and hypoxia, causing intermittent dull pain in the right abdomen. This pain usually occurs during or shortly after exercise and gradually subsides with rest. Adequate warm-up activities such as jogging and stretching should be performed before exercising to allow the body to gradually adapt to the physical activity.

3. Acute Appendicitis

Acute appendicitis may be caused by factors such as obstruction of the appendix lumen. After the appendix lumen becomes obstructed, pressure within the appendix cavity increases, allowing bacterial proliferation and toxin secretion, which damages the appendix mucosa and triggers inflammation. Inflammatory stimulation of nerve endings in the appendix leads to intermittent dull pain or persistent distending pain in the lower right abdomen, which may be accompanied by symptoms such as nausea, vomiting, and fever. Patients should follow medical advice to use medications such as Ceftriaxone Sodium for Injection, Metronidazole Tablets, and Ornidazole Sodium Chloride Injection for anti-infective treatment.

4. Cholecystitis

Cholecystitis is mostly caused by cystic duct obstruction, bacterial infection, and other factors. After cystic duct obstruction, bile drainage is impaired, irritating the gallbladder mucosa and triggering inflammation. Inflammatory processes stimulate nerves around the gallbladder, resulting in intermittent dull pain in the upper right abdomen, which may be accompanied by symptoms such as nausea, vomiting, and loss of appetite. Patients can use medications such as Xiaoyan Lidan Tablets, Ursodeoxycholic Acid Capsules, and Cefoperazone Sodium and Sulbactam Sodium for Injection for treatment under medical guidance.

5. Ureteral Stones

Ureteral stones may form when components such as calcium, oxalate, and uric acid in urine reach high concentrations in the kidney or ureter, leading to crystallization and gradual aggregation. When stones move within the ureter, they may irritate the right ureteral mucosa, causing intermittent dull pain in the right abdomen, which may also be accompanied by symptoms such as hematuria, frequent urination, and urgency. Patients can, under medical advice, undergo procedures such as extracorporeal shock wave lithotripsy or ureteroscopic lithotripsy and stone removal to expel the stones, or use medications such as Diclofenac Sodium Sustained-Release Tablets, Tamsulosin Hydrochloride Sustained-Release Capsules, and Pishi Keli to relieve pain under medical supervision.

In daily life, it is important to maintain good eating habits and balanced nutrition, while consistently engaging in moderate physical activity and paying attention to appropriate exercise methods and intensity.
