The cause of persistent distension and pain slightly above the right side of the navel
I always feel a distended pain in the upper right area near my navel, especially noticeable after meals or when pressing on it, and occasionally accompanied by a slight sensation of heaviness. There are no other obvious discomforts. What could be the possible cause of this?

Persistent distension and pain slightly above and to the right of the navel may be caused by various factors.
Digestive system issues such as gastritis, gastric ulcer, or duodenal ulcer, gallbladder diseases (cholelithiasis, cholecystitis), and abnormal liver function can all lead to discomfort or pain in the upper abdomen or right upper quadrant. Appendicitis is also a common cause; in its early stages, the pain may present as discomfort slightly above and to the right of the navel before potentially shifting to the right lower abdomen.
Gallbladder diseases such as cholecystitis and gallstones can also cause pain in this area, especially when gallstones lead to obstruction or infection, resulting in more pronounced pain. Kidney stones or ureteral stones may sometimes cause abdominal pain, particularly when the stones are moving, leading to severe colicky pain.
For female patients, gynecological conditions such as ovarian cysts and endometriosis may also cause abdominal discomfort. In addition, muscle strain, rib fractures, or muscle tension could also be potential causes of pain.
It is recommended to seek timely medical evaluation and undergo detailed examinations, including but not limited to blood tests, abdominal ultrasound, and CT scans, to establish a clear diagnosis and receive targeted treatment.
