Causes, Symptoms and Treatment of Lower Back Pain and Diarrhea

Lower back pain and diarrhea can be symptoms of a variety of medical conditions. Both symptoms are common. If you have diarrhea and back discomfort at the same time, it could mean you have a serious illness. Both can occur simultaneously for a variety of reasons. Some conditions that may result in both are tumor growth, enteropathic arthritis, IBS, and constipation. It is important to get medical attention if symptoms get worse. 

Lower Back Pain & Bowel Problems

Bowel diseases damage the small intestines. Bowel issues are mainly caused by smoking, nutrition, microbiological and immunologic factors, and Crohn's disease in the family. Constipation, diarrhea, gas, and abdominal pain are some of the most common signs of bowel problems. The link between gastrointestinal issues and lower back pain is often overlooked. Bowel issues and lower back pain are definitely linked. Abdominal pain and bloating suggest irritable bowel syndrome. In addition to bloating and gas, IBS often causes extraintestinal symptoms. This includes sleep issues, headaches, urination issues, exhaustion, muscle discomfort, pelvic or jaw pain, and back pain.

The Reasons For Lower Back Pain And Diarrhea

Your lower back ache and diarrhea may be unrelated, but persistent symptoms suggest a medical explanation. Some possible reasons for these symptoms include:


The appendix, a tiny organ in the lower right abdomen from the first section of the colon, is inflamed in appendicitis. It can lead to severe lower back pain and diarrhea simultaneously. Other symptoms are:

  • Fever

  • Appetite loss

  • Urinating burn

  • Urinating frequently or urgently

  • Urine is cloudy or foul

Fecal Impaction

A huge, hard, dry stool lodged in the rectum is called feces impaction. Chronic constipation, commonly caused by laxative use, is the main cause. Constipated feces are dry and hard to pass.

  • Cramping

  • Bloating

  • Bleeding

  • Unexpected weight loss

  • Anemia

Irritable Bowel Syndrome

Irritable bowel syndrome is a common issue nowadays. Its symptoms include:

  • Bloating

  • Stomach pain

  • Diarrhea

  • Constipation

  • Cramps

IBS might be painful, but it doesn't cause cancer or damage the colon like inflammatory bowel illnesses. In addition to stomach pain, it can cause lower back pain and diarrhea. It might produce constipation or alternate diarrhea and constipation.  


Doctors call painful menstrual periods dysmenorrhea. An analysis found that 45–95% of menstruators have dysmenorrhea. Some people feel pelvic discomfort that radiates to the lower back in addition to abdominal cramping. Additional dysmenorrhea symptoms are: 

  • Nausea

  • Vomiting

  • Exhaustion

  • Sleep troubles

Over-the-counter ibuprofen, aspirin, and naproxen help many dysmenorrhea sufferers. If these therapies fail, back pain doctors in Dallas may prescribe harsher painkillers or birth control. They may also suggest dysmenorrhea testing to establish the cause. Alternative treatments include lifestyle changes. The back specialist in Dallas can recommend different lifestyle changes like regular exercise, quitting smoking, and getting enough sleep to lessen the pain.

Other Conditions That Could Have Caused It?

Finding out what is causing your back pain and bloating might depend on which sign shows up first. Many illnesses might create worrisome symptoms. Following are some of them:

  • Menstruation: When the uterus sheds its lining once a month, it is normal to experience pain, cramps, or discomfort. Lower back cramps may accompany period cramps.

  • Premenstrual syndrome: PMS affects cisgender women's emotions, health, and behavior during menstruation. Lower back and stomach pain or bloating may occur.

  • Endometriosis: This discomfort may manifest in the abdominal region or the back, or it may occur simultaneously in both areas.

  • Pregnancy: While you're pregnant, you might have both stomach cramps and back pain. Labor may occur if the cramps are worse and more frequent than menstrual cramps. Constipation can cause bloating. Back pain frequently results from fetal growth and an altered center of gravity. Changing hormones and extra stress on the gastrointestinal tract can cause lower back pain and diarrhea during pregnancy.

Severe Lower Back Pain And Diarrhea Treatments

Low back pain and diarrhea are usually caused by muscle tension and spasm and do not require surgery. Your pain can be treated with medicine or the best pain management in Dallas. Here are some:


  • Try acetaminophen (Tylenol), nonsteroidal anti-inflammatory drugs including aspirin, naproxen, and ibuprofen, gabapentin, or pregabalin.

  • Acetaminophen diminishes fever and discomfort, but not inflammation. Antiseizure drugs gabapentin and pregabalin block pain.

  • Painkillers like codeine may be recommended for severe back discomfort. However, opioids cause habituation, constipation, and lightheadedness; thus, they should be avoided and taken carefully. 

See a physiatrist if you have no evident injury to explain your pain. This physical medicine professional can evaluate back discomfort and recommend nonsurgical therapies like physical therapy.

The case for surgery must be compelling, as most low-back pain patients recover without medical intervention. Eighty percent of sciatica patients heal without surgery. The most obvious back surgery indications include severe progressive nerve issues, bowel or bladder dysfunction, and cauda equina syndrome.

If MRI or electromyogram results match the patient's symptoms, back surgery may be considered. The best orthopedic spine specialists in Ennis can recommend different surgery options according to your disease range. Back pain may require surgery in severe circumstances when other treatments fail. Common methods include:

  • Discectomy, including microdiscectomy and minimally invasive lumbar discectomy, is the surgical excision of a portion of a herniated disc.

  • Spinal fusion is a bone implant that facilitates the fusion of the vertebrae.

  • A spinal laminectomy removes the lamina to increase space and minimize inflammation.


There are several reasons for abdominal pain, lower back pain and diarrhea. Try to see if symptoms go away on their own, unless the pain is severe or accompanied by other symptoms.
