WebMD Â® Digestive Disorders Community Visceral hypersensitivity basically means that the inside of your intestinal tract is 'touchier' than normal. Let's say you had a 'scale' in your GI tract that registered 'stretch' of the walls. If something move through them and a normal stretch of the walls produces no sensation except a slight feeling of 'something is there,' a person with visceral hypersensitivity will feel like the tract is being stretched to 2x it's normal diameter.

delayed hypersensitivity type II hypersensitivity. type IV reaction. A slowly developing cell-mediated immune response in which T helper 1 lymphocytes respond to specific antigen by releasing cytokines, some of which activate macrophages, as occurs in tuberculin reaction, graft rejection, some autoimmune diseases, etc.

- Chronic hypersensitivity pneumonitis. Chronic disease occurs in people with long-term low-level antigen exposure (such as owners of birds) and manifests as onset over months to years of exertional dyspnea, productive cough, fatigue, and weight loss.

Hypersensitivity reaction - types, symptoms, treatment and allergy There are four types of hypersensitivity reaction, classified according to the way in which the ALLERGEN or ANTIGEN activates the reaction. The classic allergic reaction is the type I hypersensitivity reaction, with exposure to an external substance (the allergen) initiating the IMMUNE RESPONSE.ymptoms vary with the type and severity of the hypersensitivity reaction. Itching and skin rash or URTICARIA (hives) are common with type I hypersensitivity reactions. Symptoms may involve the airways (allergic asthma) or gastrointestinal tract (food allergies).

- They also had nausea, vomiting, anxiety, feeling of impending death which further gives more warning signals to slow down. For the sensory characteristics of visceral pain -- “ %ot evoked from all viscera ”, it is known that not all internal organs are sensitive to pain especially for solid organs e.g. liver parenchyma.

Hypersensitivity Pneumonitis Hypersensitivity pneumonitis (HP) is a spectrum of immune-mediated disorders characterized by diffuse inflammation of interstitial lung, terminal bronchioli, and alveoli. Inflammation is caused by prolonged or frequent exposure of inhaled antigens generally less than 5 µm in size.

Hypersensitity, And Types of Hypersensitivity I, II, III, IV Hypersensitivity refers to excessive, undesirable (damaging, discomfort-producing and sometimes fatal) reactions produced by the normal immune system. Hypersensitivity reactions require a pre-sensitized (immune) state of the host. Hypersensitivity reactions can be divided into four types: type I, type II, type III and type IV, based on the mechanisms involved and time taken for the reaction. Frequently, a particular clinical condition (disease) may involve more than one type of reaction.

What is Hypersensitivity? Hypersensitivity is a term that is used to identify situations in which some type of substance or medication triggers an unusually strong and adverse reaction from the immune system. In some instances, hypersensitivity reactions can be extremely uncomfortable, cause permanent damage, or even result in death.

- BACKGROUND AND OBJECTIVES: Abdomen is the most frequent site for acute or chronic painful syndromes, for referred pain from distant structures or for pain caused by systemic injuries. Abdominal visceral pain is induced by hollow viscera or parenchymal viscera walls stretching or by peritoneal stretching.

Visceral pain Visceral pain. 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.

visceral visceral pertaining to the viscera or internal organs. Hence visceral afferents the components of the peripheral nervous system that carry information from the organs. The outgoing nerves to the viscera are the sympathetic and parasympathetic nerves of the autonomic nervous system but are not usually known as visceral efferents. visceral pertaining to a viscus.

Visceral Hypersensitivity: A Major Source of Abdominal Pain Some people are troubled by such a problem called visceral hypersensitivity. The phenomenon of hypersensitivity involves the nervous system. At some point, the irritation to a particular organ system like the skin or the gut leads to the sensitization of the nervous system, the alarm system.

âvisceralâ vs âemotionalâ In my opinion the best way to distinguish between these terms is to recognize that visceral reactions IS a type of deep emotional reaction, the other variant being a deep cerebral emotional reaction. I do not agree with the notion that emotional responses are always non-intellectual. This is a misleading notion.p vote 2 down vote. I think that visceral sometimes doesn't relate to what we normally describe as feelings. It seems that a visceral reaction to something may often also connect with a strong emotional response to the same moment or stimulus.

- Hypersensitivity refers to having an extreme sensitivity to stimulation of the senses, i.e., touch, sight, hearing, taste, and smell. Children who are hypersensitive may complain about sensory stimuli that seem minor to others.

Abdominal Somatic Pain Vs Visceral Vs Abdominal Referred Pain As compared to somatic pain, visceral pain is dull and poorly localized. And it is referred to mid line. As compared to somatic where muscle tenderness is observes, in visceral pain reflex sweating, salivation, nausea, vomiting and increased heart rate may be observed. Colic is one form of visceral pain that could be due to intestinal obstruction, passage of gallstones in biliary ducts, or passage of stone in the ureter.

- What is central sensitization? Central sensitization is a condition of the nervous system that is associated with the development and maintenance of chronic pain. When central sensitization occurs, the nervous system goes through a process called “wind-up” and gets regulated in a persistent state of high reactivity.
