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.
Viscero-visceral referral: happens when one organ with afferent nerves close to another organ is sensitized or inflamed (in this case any of the abdominal viscera) [10] Viscero-somatic referral: any pain in the viscera that causes pain in the muscle, bone, and skin (of the abdomen in case of abdominal pain)
Chronic visceral pain from mechanical factors is caused by external compression of internal organs, internal organ traction involving ligaments and vessels, or internal obstructions, such as stones or stenosis, which can block hollow viscera and cause dilation above the obstruction.
All-cause mortality (death from any cause) What’s more, higher visceral fat is associated with health risks like hardened arteries, regardless of body mass index (BMI). Obesity, in general, can ...
Referred pain, also called reflective pain, [1] is pain perceived at a location other than the site of the painful stimulus.An example is the case of angina pectoris brought on by a myocardial infarction (heart attack), where pain is often felt in the left side of neck, left shoulder, and back rather than in the thorax (chest), the site of the injury.
Most pain resolves once the noxious stimulus is removed and the body has healed, but it may persist despite removal of the stimulus and apparent healing of the body. Sometimes pain arises in the absence of any detectable stimulus, damage or disease. [3] Pain is the most common reason for physician consultation in most developed countries.
In FGID there is poor association of pain with GI motility in many functional GI disorders. These patient often have a lower pain threshold with balloon distension of the bowel (visceral hyperalgesia), or they have increased sensitivity even to normal intestinal function; Visceral hypersensitivity may be amplified in patients with FGIDs.

Specifically, chronic pain and depression cause similar changes in neuroplasticity, or the ways the brain forms new connections. For example, both alter levels of neurotransmitters such as ...
