Can constipation cause back pain? The answer is yes, and for many people, this connection explains the discomfort that often lingers in the lower back.

How to Know if Back Pain Is Due to Constipation?

To know if your back pain is caused by constipation, watch for these clues: 

• The back pain occurs or worsens around or just after bowel movements before relief.

• You have symptoms of constipation, such as infrequent or hard stools, straining, bloating, or a feeling of fullness in the abdomen.

• You experience pain in the lower back, often in the lumbar area, sometimes radiating toward the lower abdomen

• Pain tends to improve after passing stool or when the abdomen is relieved by gas. 

• There are no signs of classic mechanical back pain, like sharp shooting pain down one leg, no recent injury, nor neurological symptoms like tingling or numbness in the legs. 

If you notice several of these together, constipation is likely a contributor or even the main cause of your back pain. From here, steps like exercise, diet, and possibly targeted physical therapy or nutrition support can help.

Why Constipation Leads to Back Pain? Causes Explained

Constipation may cause back pain for several interconnected reasons: 

• Abdominal pressure and distension: Hard or blocked stool stretches the colon and increases intra-abdominal pressure, which pulls on lower back muscles and can strain ligaments. 

• Postural changes: To cope with discomfort or to avoid pressure, people may adjust posture by leaning forward or backward and stiffening the core, leading to muscle strain in the back.

• Visceral referred pain: Organs in the abdomen share nerve pathways with the back, and irritation or tension in the intestines can “refer” pain to lumbar or sacral spine regions.

• Muscle tensing: Bloating or abdominal discomfort causes involuntary muscle tightening in both the abdomen and lower back, resulting in soreness. 

• Reduced movement: Constipation often goes with reduced physical activity, which weakens core and back musculature, making back pain more likely. 

• Hydration & Electrolyte Imbalance: Low fluid intake and disturbances in electrolytes,  such as magnesium or potassium, which often accompany digestive issues, can affect muscle function.

What Does Constipation Back Pain Feel Like?

Constipation and back pain might feel like an aching heaviness rather than a sharp, stabbing sensation. Many people notice a sense of tightness across the lower back, often on both sides but more pronounced on one side, depending on where the stool is impacting.

It may feel as though pressure or fullness in the lower abdomen is pulling on the back muscles. Also, discomfort can increase when bending forward, twisting, or lifting objects. 

In some cases, there’s even a subtle cramping or spasm in the lumbar area or across the pelvis region that reinforces the feeling of tension and bloating. 

Where Is Constipation Pain in the Back Located?

Constipation back pain is located primarily in the lumbar region, sometimes extending to the sacrum and into the sides of the lower torso. It is less likely to originate in the upper back, neck, or shoulders.

Let’s now explore some simple at-home exercises to help relieve back pain caused by constipation.

5 Exercises to Help Relieve Back Pain Caused by Constipation

Exercise 1: Child’s Pose with Belly Release

Steps: 

1. Start on your hands and knees, tabletop position, and wrists under shoulders, knees under hips.

2. Slowly sink your hips back toward your heels, lowering your torso forward and resting your forehead or chin on the floor or a prop, like a block or pillow.

3. Let your belly drape heavily toward your thighs, but don’t tuck in. Breathe deeply, allowing the abdomen to relax and stretch gently.

4. Hold for 30 to 60 seconds, breathing into the lower belly with each inhale; exhale fully.

5. To release, walk your hands back toward your body, and sit up slowly.

📌 This position opens up and decompresses the abdominal region, gently stretches the lower back, and encourages movement in the intestines. 

Exercise 2: Supine Knee-to-Chest Stretch 

Steps: 

1. Lie flat on your back with legs extended and arms by your sides.

2. Bend one knee and slowly bring it toward your chest, wrapping your arms around your shin or knee. Keep the other leg straight on the floor.

3. Hold for 20‐30 seconds, breathing steadily.

4. Release, then repeat with the other leg.

5. For deeper relief, you can draw both knees in toward your chest together (double knee hug) and gently rock side to side.

📌 The main benefit is that it helps stretch the lower back, massages the intestines, and aids in colon movement.

Exercise 3: Wind-Relieving Pose

Steps: 

1. Lie on your back with knees bent and feet flat.

2. Draw both knees toward your chest, wrap your arms around them.

3. Gently rock side to side, massaging the lower back and hips.

4. Hold 30–60 seconds, breathing deeply.

5. Release by lowering one leg at a time or both slowly.

📌 Wind-relieving pose releases trapped as, helps abdominal motility, and eases tension in the lower back.

Exercise 4: Cat-Cow Stretch

Steps: 

1. Begin on hands and knees, neutral spine.

2. Inhale: drop belly toward floor, lift head and tailbone, “Cow.”

3. Exhale: round the spine upward, tuck the chin and tailbone, “Cat.”

4. Repeat slowly for 8–12 cycles, matching breath to movement.

5. Optionally pause in the most comfortable positions for extra stretch.

📌 This exercise mobilizes the spine, stimulates abdominal organs, and helps with digestion and reducing stiffness.

Exercise 5: Supine Spinal Twist

Steps:

1. Lie on your back with your arms extended out to sides in a “T” shape.

2. Bend one knee, cross it over the midline of the body toward the floor on the opposite side, keeping your shoulders grounded.

3. Turn the head to the opposite side of the bent knee for a gentle twist.

4. Hold for 30 seconds to 1 minute, breathing deeply.

5. Return to the center, repeat on the other side.

📌 The posture gives gentle twist massages to the intestines, relieves lower back tension, and helps with colon transit.

What Foods Help Relieve Constipation?

The ideal meal includes fiber, fluids, and gut-friendly foods. Here is a list of foods that support healthy bowel movements and help reduce back discomfort:

• High-fiber fruits: pears with skin, berries, apples, prunes, figs. 

• Vegetables: Leafy greens like spinach and kale, broccoli, Brussels sprouts, and carrots. 

• Whole grains: oats, barley, brown rice, quinoa. 

• Legumes: lentils, beans, chickpeas. 

• Nuts and seeds: chia seeds, flaxseeds, almonds in moderation. 

• Hydration helpers: water, herbal teas like peppermint, and clear broths. 

• Fermented Foods/Probiotics: yogurt, kefir, kimchi, to support gut flora. 

• Healthy Fats: olive oil, avocado, can help lubricate the digestive tract. 

💧 Combining these foods with adequate water, aiming for at least 8 cups or half a gallon per day, helps fiber do its job. 

What Not to Do When Constipated?

If constipated, avoid the following:

• Holding in bowel movements and delaying them.

• Relying on large doses of laxatives long-term without medical advice.

• Eating too many processed, low-fiber foods, such as white bread, chips, or sweets.

• Becoming extremely dehydrated, skipping fluids, or consuming too much caffeine without water.
