Constipation is a common and complex clinical symptom, which mainly refers to reduced frequency of bowel movements, decreased stool volume, dry stools, and straining to pass stools. Constipation rarely causes back pain symptoms in the organism. If the patient has habitual constipation, often squatting for a long time in the toilet, it may lead to soft tissue injury of the waist muscles, triggering low back pain symptoms, and there may be some indirect connection between the two. If constipated patients with low back pain symptoms, it is important to know whether there are lumbar spine diseases such as lumbar disc lesions, degenerative spondylitis, lumbar muscle strain, in addition to urinary system diseases such as kidney stones often manifested as pain in the lower back.
