Pelvic Floor Dysfunction: The Hidden Cause of Diarrhea, Constipation, and More

Pelvic floor dysfunction is a lesser-known but surprisingly common issue that can mimic—or even cause—chronic bowel problems like diarrhea, constipation, or both. If you've been told your digestive tests are "normal" but still experience bowel trouble, your pelvic floor muscles might be the missing piece.

What Is Pelvic Floor Dysfunction?

The pelvic floor is a group of muscles and ligaments at the base of your pelvis. These muscles control your bladder, bowels, and—if applicable—your uterus. When they don't contract or relax properly, it can result in pelvic floor dysfunction (PFD).

There are two main types:

• Hypotonic (weak muscles): can lead to leakage, urgency, and incomplete evacuation.
• Hypertonic (tight muscles): can cause pain, straining, and difficulty passing stool.

How Common Is It?

• Affects 1 in 5 adults, with women more often diagnosed
• Often underdiagnosed, especially in patients with bowel symptoms
• Common after childbirth, surgery, trauma, or in people with chronic straining

Symptoms to Watch For

Pelvic floor dysfunction can cause:

• Chronic constipation
• Chronic diarrhea
• Feeling of incomplete evacuation
• Straining to defecate
• Rectal pain or pelvic pressure
• Urinary urgency, frequency, or leakage
• A sensation of "falling out" or prolapse

How PFD Links to Bowel Issues

Constipation:

• Poor muscle coordination can prevent effective stool passage
• Patients may have normal colon function but still can't evacuate properly

Diarrhea:

• In some cases, PFD can cause urgency or inability to hold stool
• Misdiagnosed as IBS or food intolerance

Track Your Bowel Symptoms and Triggers

The first step to managing pelvic floor dysfunction is recognizing patterns.

Use BYTEMD or a daily journal to log:

• What you eat and drink
• Bowel movement time and consistency
• Straining or urgency levels
• Pelvic or rectal discomfort
• Physical activity
• Stress, posture, or lifting triggers

Example Entry: June 10, 2025

• Breakfast: Yogurt, banana
• Symptoms: Strained BM, feeling of incomplete emptying
• BM Time: 7:30 AM — Bristol Type 1
• Pelvic tension: High after long sitting
• Activity: Walked 30 minutes
• Water intake: 8 cups

What You Can Do

1. Biofeedback or Pelvic Floor Physical Therapy

• Gold-standard treatment for PFD
• A trained therapist helps retrain your muscles to relax and contract properly

2. Change Bathroom Habits

• Don't strain or sit too long
• Use a footstool to elevate knees above hips
• Create a regular bathroom schedule

3. Support with Diet & Hydration

• Eat fiber-rich foods (25–30g/day)
• Drink 8–10 cups of water daily
• Avoid excessive caffeine and alcohol

Final Thoughts

Pelvic floor dysfunction can be frustrating—but it's treatable. If you've had chronic diarrhea, constipation, or strange pelvic symptoms and no answers, start tracking your patterns today.
