Why Do I Feel the Urge to Defecate When My Back Hurts?

In daily life, the sensation of wanting to defecate along with low back pain is mainly associated with certain diseases. Typically, it can be caused by lumbar vertebral hyperosteogeny and kidney stones. Lumbar vertebral hyperosteogeny can compress the nerve around the anus, thus stimulating the urge to defecate. This symptom can be alleviated through conservative treatment methods. On the other hand, kidney stones are the primary factor leading to the combination of low back pain and the urge to defecate. This is because kidney stones can obstruct the bowel movement, resulting in both low back pain and constipation.

Lumbar vertebral hyperosteogeny or lumbar muscle strain can also be caused by spleen and kidney yang deficiency. Conservative treatment is generally adopted for low back pain, including massage, acupuncture, physical therapy, and tuina. Patients can also take traditional Chinese medicines that promote blood circulation, relieve swelling and pain, and dispel evil cold, such as Yaotongning Capsule. This medicine is made from Chinese medicinal herbs like Semen Strychni, Myrrha, and Eupolyphaga sinensis, which can invigorate the blood vessels, meridians, dispel dampness, and dispel cold.

When experiencing low back pain along with the urge to defecate, appendicitis and kidney stones should be considered as possible causes. Appendicitis and kidney stones are the most common reasons for low back pain and the sensation of wanting to defecate, even though there is no actual stool to pass. In such cases, an abdominal ultrasound examination can be performed to rule out appendicitis and kidney stones.

If a patient experiences trauma or fatigue that leads to injury of the psoas major muscle, the resulting pain can cause muscle contraction and spasm, increasing abdominal pressure and stimulating gastrointestinal motility, which can also lead to the sensation of wanting to defecate.

In such cases, it is generally recommended to perform stool routine and blood routine tests. If both tests show an elevated white blood cell count, bacterial enteritis should be considered, and anti-infective treatment is required. The occurrence of low back pain in these diseases is mainly due to the entry of irritating inflammatory secretions into the pelvic cavity during intestinal infection. These secretions can irritate the peritoneal membrane, causing pain in the affected area. Generally, the symptoms will alleviate as the infection improves.
