Constipation and the Pelvic Floor: How Kegel8 Can Help Protect Bowel and Bladder Health
How Can Constipation Damage Your Pelvic Floor?
Constipation doesn’t just make you feel bloated or uncomfortable — it can also damage your pelvic floor muscles. Chronic straining puts pressure on the muscles that support the bladder, womb, and bowel. Over time, this weakens them and can lead to:
-
Pelvic organ prolapse (rectal, bladder, or womb)
-
Faecal incontinence (leakage of stool or gas)
-
Urinary incontinence caused by pressure on the bladder
Constipation is linked to 70% of rectal prolapse cases, and its impact on pelvic health is considered as significant as childbirth. Recognising and treating constipation early is key to preventing long-term pelvic floor dysfunction.

What Causes Constipation?
Constipation happens when waste moves too slowly through the bowel or becomes difficult to pass. Common causes include:
-
Blockages in the bowel (anal fissures, rectoceles, tumours)
-
Nerve problems from conditions like Parkinson’s, MS, or stroke
-
Pelvic floor weakness, making stool harder to push through
-
Hormonal imbalances, which affect muscle contractions
Symptoms of Constipation
You may be experiencing chronic constipation if you:
-
Pass fewer than 3 stools a week
-
Pass hard, lumpy stools
-
Strain excessively to empty your bowels
-
Feel blocked, or incomplete emptying
-
Need to use your hands or fingers to help stool pass
If you have two or more of these symptoms for over 3 months, constipation is considered chronic.
Risk Factors for Constipation
Certain factors increase the likelihood of constipation, including:
-
Being female (linked to hormonal changes)
-
Older age
-
A low-fibre diet
-
Dehydration
-
Lack of physical activity
How to Prevent Constipation and Protect Your Pelvic Floor
1. Strengthen your pelvic floor
Straining weakens pelvic floor muscles over time. Using the Kegel8 Ultra 20 Electronic Pelvic Toner helps target and strengthen the pelvic floor, supporting better bowel and bladder control. If you find manual Kegels difficult, Kegel8 ensures the right muscles are worked automatically.
2. Improve your toilet position
A simple toilet stool like the Go Better toilet stool helps raise the knees, changing the anorectal angle to make passing stool easier and reduce strain.
3. Optimise your diet
Eat at least 30g of fibre daily from wholegrains, fruits, and vegetables. Low fibre intake is linked to constipation and bowel cancer.
4. Stay hydrated
Drink plenty of water to soften stool. Limit fruit juices which may irritate the bowel.
5. Keep moving
Regular exercise keeps your bowels active and helps prevent constipation.
6. Listen to your body
Don’t ignore the urge to go. Delaying bowel movements can worsen constipation.
7. Take your time
Allow yourself enough time in the bathroom — stress and rushing can make constipation worse.
8. Consider magnesium
Magnesium supplements may help relax muscles and ease bowel movements. A warm sitz bath with Epsom salts can also support muscle relaxation and help absorption of magnesium through the skin.
- Supplementing with magnesium – Magnesium can help to improve your muscles and get things moving.
- Indulging in a Sitz bath – An Epsom salt bath can also help your body to absorb magnesium, as well as being hugely relaxing.
