Can Constipation Cause Back Pain? What You Should Know

Constipation occurs when bowel movements are infrequent or hard to perform. Many people will experience back pain at one time or another. It can be very confusing when these two issues occur together. Constipation, which creates pressure in the body, can cause back pain. This connection can be used to find faster relief and stop the pain from returning.

Stool that stays too long in the intestines begins to harden and build up. The buildup of stool can cause the colon to stretch and put pressure on the pelvic and lower abdominal area. This pressure, which is caused by the colon being so close to your lower spine, can cause nerves to be irritated and nearby muscles to ache. Constipation can cause discomfort that develops gradually. It may even worsen over a period of several days if ignored.

How Constipation Can Cause Back Pain

The intestines press on surrounding tissue as stool builds up in the colon. The pressure on the lower back nerves can cause pain to feel deep, uncomfortable and not sharp. If the stool is tough, it can become stuck and cause intense pressure, which makes the back pain worse.

A common cause is straining when bowel movements. Extra stress is placed on abdominal muscles and the lower back when you push too hard. This repeated strain over time can cause muscle stiffness and soreness, even after you use the toilet.

Why Constipation and Back Pain Often Happen Together

Back pain and constipation are often caused by the same factors. Low-fibre foods, lack of exercise, dehydration and sitting for long periods can all slow down digestion. Sitting for long periods can cause poor posture and compress your abdomen, making it difficult for bowel movements.

Also, stress can play a part. Stress can also play a role. When stressed, the digestion slows down, and the muscles in the entire body tighten, including those of the back. Constipation can be made worse by back pain, and this combination is challenging to stop without a lifestyle change.

Which part of the back is usually affected

Constipation causes back pain that is felt most often in the lower spine area, above the hips. The area closest to the colon or rectum is where you will feel pressure due to stool accumulation. Others may feel a weight in their lower abdomen or pelvic area. Constipation is not always the cause of upper or mid-back discomfort.

Constipation may be the cause of your back pain.

Constipation may cause your back pain if the discomfort is dull, constant and not sharp. After a bowel motion or when constipation has been relieved, the discomfort usually improves. Bloating, gas and abdominal fullness are also signs. Constipation can cause back pain and digestive discomfort.

If the constipation is not the cause of your pain, and you have other symptoms such as numbness or weakness or a fever or unexplained weight loss that is unexplained, then it is best to consult a physician.

Relieve Back Pain Due to Constipation

Constipation can cause back pain. The best way to relieve it is by improving digestion. Consuming more fibre-rich foods, such as whole grains, fruits and vegetables. It softens stool and stimulates regular bowel movement. It is also necessary to drink enough water during the day, since dehydration can make stool complex and challenging to pass.

Walking or stretching can help boost bowel movements and relieve stiffness in the lower back. By responding instantly to demands to go to the toilet, you can prevent stools from getting harder to pass. If constipation continues despite your efforts, you may need to seek medical advice.

When to See a Doctor

Consult a physician if constipation continues for longer than two days and does not improve with simple lifestyle changes. Never ignore constant or severe back pain. If you experience any symptoms such as continuous abdominal pain, blood in the stool or neurological symptoms, then it is necessary to seek immediate medical attention.
