Disease description:

My mother hasn't had a bowel movement for several days, but she frequently feels a dragging pain in her abdomen along with a sensation of needing to defecate, yet she is unable to pass stool. I would like to know what causes this feeling of abdominal heaviness and the inability to defecate despite the urge?

Aching abdominal pain with a feeling of needing to defecate but being unable to may be caused by pathological factors or constipation. Intestinal inflammations such as colitis and proctitis can lead to congestion and swelling of the intestinal mucosa, possibly causing a sensation of heaviness and pain in the abdomen. In daily life, insufficient water intake or an unreasonable diet may result in dry, hardened stools, leading to the sensation of needing to pass stool but being unable to do so.
