Pain in the abdomen and constant urge to defecate in men is a normal physiological reaction if it is a simple excretory process. If it lasts for a longer period of time and occurs repeatedly with other symptoms, it should be considered to be caused by organic diseases. Simple abdominal pain and normal bowel movements are transient intestinal obstruction caused by excessive food accumulation and indigestion, which can usually be relieved by dietary modification and good abdominal warmth. However, if the symptoms of abdominal pain, diarrhea and abdominal distension persist for a long time, it should be considered as a manifestation of gastroenteritis, and you should go to the hospital for relevant examinations to clarify the diagnosis before taking medication or taking appropriate treatment measures. Especially for the acute occurrence of abdominal pain and accompanied by nausea, vomiting and other symptoms, it is necessary to promptly seek medical attention and early treatment. In addition, men with abdominal pain and the desire to defecate may also be related to diseases of the urinary system, such as prostatitis, and therefore need to pay attention to.
