Visceral pain is pain that results from the activation of nociceptors of the thoracic, pelvic, or abdominal viscera (organs). Visceral structures are highly sensitive to distension (stretch), ischemia and inflammation , but relatively insensitive to other stimuli that normally evoke pain such as cutting or burning.
Studies have shown altered muscle contractility and tone, bowel compliance, and transit may contribute to many of the gastrointestinal symptoms of FGID which may include diarrhea, constipation, and vomiting. [20] Visceral hypersensitivity In FGID there is poor association of pain with GI motility in many functional GI disorders.
Theories include combinations of "gut–brain axis" problems, alterations in gut motility, visceral hypersensitivity, infections including small intestinal bacterial overgrowth, neurotransmitters, genetic factors, and food sensitivity. [2] Onset may be triggered by a stressful life event, [16] or an intestinal infection. [17]
Reviewing the presence of non-abdominal symptoms (e.g., fever, chills, chest pain, shortness of breath, vaginal bleeding) that can further clarify the diagnostic picture. Using Carnett's sign to differentiate between visceral pain and pain originating in the muscles of the abdominal wall. [19]
However, SUDD occurs when only abdominal pain with bowel habit change is present, without any other systemic symptoms of diverticulitis like fever, elevated white blood cell count, elevated C-reactive protein. [6] Low grade inflammation of the colonic mucosa within the diverticulum and visceral hypersensitivity are also thought to cause SUDD. [6]
Functional abdominal pain syndrome is a functional gastrointestinal disorder. [4] Functional gastrointestinal disorders (FGD) are common medical conditions characterized by recurrent and persistent gastrointestinal symptoms caused by improper functioning of the enteric system in the absence of any identifiable organic or structural pathology, such as ulcers, inflammation, tumors or masses.
