Constipation is most often attributed to diet and hydration, however you may be surprised to know that one of the most overlooked contributors to constipation is scar tissue. Thats right! Whether from surgery, injury, or chronic inflammation, scar tissue can physically restrict bowel movement and as well as amp up the sympathetic bias (fight or flight) of the autonomic nervous system, leading to slowed gut motility and tension in the pelvic floor muscles. Understanding how scar tissue and autonomic nervous system imbalance affect digestion and muscle tension is key to finding lasting relief.

How Scar Tissue Impacts Bowel Function

Scar tissue is the body’s natural response to injury, forming fibrous connections (and often adhesions) that help close and heal wounds. However, these adhesions can create tight, restrictive bands around the intestines, interfering with peristalsis (the wave-like muscle contractions that move stool through the digestive tract). This can lead to:

• Mechanical obstruction: Adhesions can tether or kink sections of the bowel, making it harder for stool to pass.  
• Reduced motility: Restricted movement in the intestines slows transit time, leading to hardened stool and constipation.
• Discomfort and bloating: Tight or restricted areas in the gut can cause pain, pressure, and distention, worsening digestive symptoms.

Scar tissue isn’t just a physical barrier—it also influences the nervous system, which plays a crucial role in bowel function.

The Nervous System’s Role in Digestion

The autonomic nervous system (ANS) regulates digestion, with two key branches:

• The sympathetic nervous system (fight-or-flight): When activated, it slows digestion to conserve energy for perceived threats.
• The parasympathetic nervous system (rest-and-digest): This promotes peristalsis and normal digestive function.

Chronic stress, trauma, or scar tissue can push the body into a prolonged sympathetic state, reducing gut motility and contributing to constipation. Many people with chronic constipation have an imbalance in their ANS, making it essential to support vagus nerve function and encourage parasympathetic activation.

Strategies to Address Scar Tissue and Nervous System Imbalance

1. Manual Therapy for Scar Tissue Release

Hands-on techniques can help break up adhesions and restore movement in the digestive tract:

• Myofascial release: A gentle, sustained pressure technique that targets fascial restrictions.
• Visceral manipulation: A specialized therapy that enhances organ mobility and function.
• Abdominal massage: Encourages circulation and helps mobilize the intestines.

2. Supporting the Vagus Nerve for Better Gut Motility

Since the vagus nerve controls digestion, stimulating it can help shift the nervous system into a parasympathetic state. Effective strategies include:

• Diaphragmatic breathing: Deep belly breathing activates the vagus nerve and promotes relaxation.
• Gargling and humming: These simple exercises stimulate vagal activity.
• Cold exposure: Brief cold showers or splashing cold water on the face can enhance vagus nerve tone.

3. Stress Reduction and Nervous System Regulation

Chronic stress perpetuates digestive dysfunction. Incorporating stress management techniques can improve gut motility:

• Mindfulness, prayer and meditation: Reduce overall stress and promote relaxation.
• Yoga and gentle movement: Help release physical tension and improve nervous system balance.
• Acupuncture: Supports nervous system regulation and gut function.
• Dolphin Neurostim: used to both up-regulate parasympathetic tone of autonomic nervous system as well as softening scar restrictions.

Restoring Gut Function for Lasting Relief

Addressing constipation requires more than just fiber and water—it demands a comprehensive approach that includes scar tissue release and nervous system regulation. By incorporating manual therapy, vagus nerve activation, and stress management, you can restore normal bowel function and break free from chronic constipation.
