Constipation can cause back pain, which occurs when irregular bowel movements create a blockage that puts substantial pressure on nearby organs and the lower back. This pressure can lead to varying degrees of pain, from mild to severe, and if constipation persists for more than three weeks, seeking professional medical advice is essential to manage the condition and avoid further complications.

Understanding Constipation and Back Pain

What is Constipation?

Constipation means having fewer bowel movements than usual. It's often described as having less than three per week.


  • Low Fiber Diet: Not eating enough fruits, vegetables, and whole grains can lead to constipation.
  • Insufficient Water Intake: Dehydration or not drinking enough water daily can harden stools, making them difficult to pass.
  • Lack of Physical Activity: A sedentary lifestyle contributes to slowed digestion.
  • Medications: Certain drugs, including painkillers, antidepressants, and iron supplements, can cause constipation as a side effect.
  • Ignoring the Urge to Go: Regularly delaying bowel movements can make it harder to pass stools over time.
  • Stress: High levels of emotional stress can affect bowel regularity.
  • Health Conditions: Disorders like diabetes, thyroid issues, and irritable bowel syndrome (IBS) can lead to constipation.
  • Age: The digestive system can become less efficient with age, increasing constipation risk.

Why It Matters:

  • Regular bowel movements are crucial for eliminating waste from your body. Constipation can cause discomfort and affect your quality of life.

Quick Stats by PubMed Central (PMC)

  • Prevalence: Up to 20% of adults experience constipation.
  • Note: It's more common in women and the elderly.

Exploring Back Pain

Back pain is a widespread health concern, manifesting in various forms such as lower back pain, pain near the kidneys, upper back pain, and conditions like sciatica. These types can range from a mild, nagging ache to severe, debilitating pain affecting daily activities. 

Common Causes:

  • Straining muscles or ligaments.
  • Not staying active enough.
  • Poor posture, especially over time.
  • Certain medical conditions, like disk issues.

The Connection Between Constipation and Back Pain

How Constipation Affects the Back

The link between constipation and back pain might seem surprising, yet it's supported by physiological connections. When constipated, the excessive stool accumulation in the colon can put pressure on the lower region. 
Understanding how constipation can lead to back pain involves recognizing the pressure dynamics within the abdomen and lower back.

More common cases:

  • Lower Back Pain: Constipation can cause lower back pain due to the colon's proximity to the lower back area. When the colon is full, it can exert pressure on the lower back muscles and nerves, leading to discomfort or pain.
  • Pain Near the Kidneys: The pressure from a distended bowel can also affect areas near the kidneys, even though the kidneys themselves may not be the source of the pain. The sensation of pain near the kidneys due to constipation underscores the significant impact of bowel health on overall well-being.

Less common cases: 

  • Upper Back Pain: Less common than lower back pain, it's usually associated with posture issues, muscle overuse, or trauma. While less directly linked to constipation, severe cases of bloating and gas can lead to discomfort felt up through the upper back.
  • Sciatica: Characterized by sharp, shooting pain traveling from the lower back down through the leg, this condition is caused by irritation or pressure on the sciatic nerve. Constipation can contribute to sciatica pain if excessive bowel pressure affects the nerves.

When the Roles are Reversed: Back Pain Leading to Constipation

Interestingly, the relationship between back pain and constipation can also be reversed. Conditions like neurogenic bowel, resulting from spinal injuries or diseases affecting the nerves of the bowel, can lead to constipation. 

Neurogenic Bowel: This is a condition that might happen if there are spinal injuries or diseases. It affects the nerves that help the bowel move properly.

  • What Causes It? Injuries to the spine or certain diseases can harm the nerves.
  • The Result: These nerve issues can make it hard for your body to have regular bowel movements, leading to constipation.

Identifying Your Symptoms

Symptoms of Constipation

To better understand if what you're experiencing is constipation, here's a checklist for self-assessment. Note any discomfort or pain in different back areas, as severe constipation might also manifest in these ways.

  • Fewer than three bowel movements a week.
  • Hard, dry, or lumpy stools.
  • Straining or pain during bowel movements.
  • Feeling as though there's a blockage in your rectum that prevents bowel movements.
  • Feeling as though you can't completely empty the stool from your rectum.
  • Back Discomfort: Notice if there's discomfort or pain in the lower back or areas near the kidneys, as constipation can contribute to this sensation.

Recognizing Back Pain Symptoms

Back pain varies greatly, but understanding common versus severe symptoms can help in identifying the cause and deciding on the course of action.

Common Symptoms:

  • Muscle ache.
  • Shooting or stabbing pain.
  • Pain that radiates down your leg.
  • Limited flexibility or range of motion of the back.

Remember, addressing symptoms early and adopting a holistic approach to treatment can significantly improve your quality of life.

Comprehensive Treatment Options

Home Remedies and Lifestyle Changes

Managing constipation often begins with adjustments to your diet and lifestyle. Consider the following tips:

  • Increase Fiber Intake: Include more fruits, vegetables, whole grains, and legumes in your diet.
  • Stay Hydrated: Drink plenty of water throughout the day.
  • Regular Exercise: Engage in daily physical activity, such as walking, swimming, or yoga.

Medical Treatments for Constipation

For those who need a little extra help, over-the-counter options can provide relief:

  • Fiber supplements can help bulk up your stool.
  • Stool softeners can make it easier to pass stools.
  • Laxatives should be used as a last resort and under the guidance of a healthcare professional.

Addressing Back Pain

Back pain resulting from or contributing to constipation might require targeted treatments:

  • Stay Active: Regular physical activity helps keep your digestive system moving and strengthens the muscles supporting your back. Aim for at least 30 minutes of moderate exercise most days of the week.
  • Maintain Good Posture: Whether sitting or standing, maintaining good posture reduces the strain on your back muscles and spine.
  • Physical Therapy: Can improve flexibility and strengthen the back muscles.
  • Chiropractic Care: Adjustments can help realign the spine and relieve pressure.
  • Heat Therapy: Applying heat can soothe muscle pain and stiffness.

For back pain related to constipation, focusing on resolving the digestive issue may alleviate the discomfort in the lower back and near the kidneys.

Innovative Treatments and Therapies

Exploring new or less common treatments can also offer relief:

  • Acupuncture: May reduce chronic pain by stimulating nerve-rich areas.
  • Biofeedback: Helps individuals control bodily processes more effectively, potentially improving bowel movement regularity.

When to See a Healthcare Provider

While many cases of constipation and back pain can be managed with home care, there are times when seeking professional medical advice becomes essential. Recognizing the signs that warrant a visit to a healthcare provider can help in addressing potential issues before they escalate. Here’s when to make that call:

  • Persistent or Worsening Symptoms: If your constipation or back pain persists for more than a few weeks or worsens despite home treatment, it’s time to see a doctor.
  • Severe Pain: Severe lower back pain, especially if it limits your mobility or is accompanied by numbness or tingling in your legs, can indicate a more serious condition.
  • Discomfort Near the Kidneys: Pain or discomfort in the areas around your kidneys, particularly if accompanied by fever or urinary symptoms, could suggest an underlying issue that needs immediate attention.
  • Signs of Sciatica: If you’re experiencing symptoms resembling sciatica, such as sharp pain radiating down one leg, alongside constipation, consult a healthcare provider to rule out nerve compression.
  • Other Alarming Symptoms: Presence of blood in your stool, unexplained weight loss, or severe abdominal pain are signs that should never be ignored and require prompt medical evaluation.
