What if your organs could feel pain from sensations that normally shouldn’t hurt?
This can happen with visceral hypersensitivity, a condition in which the pain threshold of internal organs becomes unusually low. Normal processes such as digestion, intestinal movement or bladder filling may then feel painful or uncomfortable.
The condition is strongly associated with functional gastrointestinal disorders, particularly irritable bowel syndrome (IBS). Studies suggest that visceral hypersensitivity is an important contributor to abdominal pain in many people with IBS, although it is not present in every patient.
The mechanism involves the brain–gut axis. Nerves within the digestive tract continuously detect stretching, movement, chemical changes and other signals. When these pathways become sensitised, ordinary signals can be amplified before reaching the brain.
Several factors may contribute. Previous gastrointestinal infection, inflammation, repeated pain, psychological stress, altered gut microbiota and changes in intestinal permeability have all been investigated. Both peripheral nerves and central pain-processing pathways may play a role.
Symptoms can include abdominal pain, bloating, nausea, indigestion and altered bowel habits. The discomfort may feel deep, diffuse or difficult to pinpoint. Some people may also experience increased sensitivity to touch, temperature or other sensations.
Visceral hypersensitivity is not simply “pain in the gut.” It reflects a complex interaction between the organs, nerves and brain.
Diagnosis usually focuses on symptoms and exclusion of other structural or inflammatory conditions. Special tests that measure visceral sensitivity are mainly used in research rather than routine clinical practice.
Treatment depends on the underlying condition and may involve dietary strategies, medications, psychological therapies and approaches that target abnormal pain processing. The goal is not only to treat the organ, but also to regulate the communication between the gut and the nervous system.
Could a normal digestive sensation feel painful if your nervous system turned up the volume?
Have you ever experienced pain that seemed much stronger than the physical trigger?
