Unveiling Visceral Hypersensitivity: A Deeper Look at Heightened Gut Sensitivity

Within the blog post on Overactive Gastrocolic Reflex (OGR), visceral hypersensitivity (VH) was mentioned as a potential contributing factor. Here’s a dedicated section to delve deeper into VH and its role in digestive discomfort:

What is Visceral Hypersensitivity?

  • Visceral hypersensitivity (VH) refers to an increased sensitivity of the visceral organs,  particularly those in the gastrointestinal (GI) tract, to stimuli. In simpler terms, your gut becomes hypersensitive, perceiving normal sensations like bloating or distention as uncomfortable or even painful. This heightened sensitivity can play a significant role in various digestive conditions, including OGR.

How Does Visceral Hypersensitivity Manifest?

People with VH might experience a range of symptoms in response to everyday stimuli in the gut, such as:

  • Abdominal pain or cramping: Even mild distention or gas buildup can trigger cramping or aching sensations in the abdomen.
  • Bloating: A feeling of excessive fullness or tightness in the belly can be a prominent symptom.
  • Increased Urgency: The normal urge to have a bowel movement can be amplified, leading to a sudden and strong need to use the restroom.
  • Changes in Bowel Habits: VH can sometimes contribute to diarrhea or constipation, depending on the individual’s gut motility patterns.

What Causes Visceral Hypersensitivity?

The exact cause of VH remains under investigation, but several factors are believed to contribute:

  • Abnormal Gut Motility: Disruptions in the rhythmic contractions of the gut muscles can lead to irregular movement and heightened sensitivity.
  • Changes in Gut Microbiome: An imbalance in the gut bacteria composition might play a role in VH by affecting nerve signaling and gut sensitivity.
  • Central Nervous System Involvement: Communication pathways between the gut and the brain might be altered in VH, leading to misinterpretations of normal gut sensations as pain.
  • Low-Grade Inflammation: Chronic, low-level inflammation in the gut lining can contribute to VH by sensitizing nerves.

The Link Between Visceral Hypersensitivity and OGR:

In OGR, the communication between the stomach and colon becomes hyperactive. When someone with VH also has OGR, the already heightened sensitivity in the colon is further amplified by the strong signals from the stomach after eating. This can lead to a more intense and uncomfortable response, explaining the cluster of symptoms characteristic of OGR.

Management Strategies for Visceral Hypersensitivity:

While there’s no cure for VH, various strategies can help manage its symptoms and improve overall digestive well-being:

  • Dietary Modifications: Identifying and avoiding food triggers that worsen gut sensitivity is crucial. A low FODMAP diet might be helpful for some individuals.
  • Stress Management Techniques: Stress can exacerbate VH symptoms, so incorporating stress-reduction techniques like yoga, meditation, or deep breathing exercises can be beneficial.
  • Medication: In some cases, medications like antispasmodics (to relax gut muscles) or antidepressants (at low doses to modulate gut function) might be prescribed.
  • Cognitive Behavioral Therapy (CBT): CBT can help identify and change negative thought patterns that might worsen VH symptoms.


Visceral hypersensitivity can significantly impact your digestive comfort. By understanding the condition and implementing effective management strategies, you can work towards reducing gut sensitivity and achieving a calmer digestive experience. If you suspect you might have VH, discussing your concerns with a healthcare professional is crucial for proper diagnosis and personalized management.
