Help! ! ! My father is 48 years old. For two years, his stomach has been aching in the lower left corner. My father has been examining kidney calculi since he finished the operation.

1, gastrointestinal dysfunction or intestinal flora imbalance-can appear left lower abdominal pain, some can appear diarrhea, some show constipation, anyway, the symptoms are different-

2. If the treatment is ineffective, superficial function is unlikely to cause. It is necessary to consider the etiology of intestinal organic diseases, such as intestinal polyps, tuberculosis and tumors. And it is really necessary to have a general examination.

Tumors are generally thin, with anemia and gastrointestinal bleeding. -There is a big gap between early detection and late detection of tumors, so whether your father has the above performance or not, it is recommended that you do abdominal CT plain scan+tumor markers+blood routine+fecal occult blood.

Colonoscopy-look for polyps. Some intestinal polyps are just pain, and some will have stool changes-just remove the polyps.

Tuberculosis is rare at your father's age. Anyway, colonoscopy can determine whether there is.

If everything is normal, it is probably intestinal adhesion, which is most likely to happen after surgery. This is related to personal physique, just like cutting a mouth with a knife. Some people will have scars, and some people will get nothing. Usually dull pain, sometimes fierce, sometimes normal stool, sometimes constipation,

I suggest that you'd better be hospitalized. Your father was in middle age and suffered for two years. You should check it and solve the problem as soon as possible. If there is no big problem, at least your family will feel at ease.
