1,518 Possible Causes for Dermatographia, Fainting Spells, Hypersensitive to Stimuli

  • Urticaria

    Commonly, acute urticaria has an allergic basis as a type I hypersensitivity state mediated by IgE.[] Other causes include: infections, including viruses exercise anxiety or stress sun exposure exposure to cold, such as cold water or snow contact with chemicals scratching (dermatographia[] Pressure Urticaria –Pressure urticaria is a form of hives and wheals that develop in response to physical pressure (similar to dermatographia).[]

  • Systemic Mastocytosis

    When activated by IgE or other stimuli, mast cells release preformed mediators of inflammation.[] […] usually occurs as a solitary lesion in infants. systemic mastocytosis signs and symptoms: constitutional; fatigue, fever, weight loss skin manifestations; urticaria, pruritus, dermatographia[] These mediators initiate a leukocyte–cytokine cascade that contributes to the acute and delayed hypersensitivity reactions and the various cutaneous and systemic manifestations[]

  • Hypersensitivity

    […] marked sensitivity/reactivity to innocuous stimuli hypersensitivity An excessive reaction, local or systemic, or inappropriate immune response to an antigen.[] Dentin hypersensitivity was evaluated at baseline and following 4 and 8 weeks of treatment through assessment of responses to evaporative (air) and tactile stimuli [measured[] […] by the Schiff sensitivity scale/a visual rating scale (VRS) and tactile threshold, respectively], and using the Dentin Hypersensitivity Experience Questionnaire (DHEQ, a[]

  • Orthostatic Hypotension

    Individuals with pure autonomic failure have marked hypersensitivity to all pressor and depressor stimuli.[] This is different from a syncope caused by cardiac problems because there are known triggers for the fainting spell (standing, heat, emotion ) and identifiable prodromal symptoms[] Water ingestion - -drinking 16 oz of water over 5 minutes can prevent a fainting spell (Lu et al, 2003)..[]

  • Syncope

    Stimuli can also include forceful coughing, turning of the neck or wearing a tight collar (carotid sinus hypersensitivity), or urinating (micturition syncope).[] General Information Syncope, often referred to as a fainting spell, is the abrupt and brief loss of consciousness due to a temporary lack in blood flow to the brain.[] For individuals who have problems with chronic fainting spells, therapy should focus on recognizing the triggers and learning techniques to keep from fainting.[]

  • Fibromyalgia

    Research suggests that people with fibromyalgia are hypersensitive to stimuli that are not painful to others, perhaps due to a reduced blood flow to the portion of the brain[] Research suggests that fibromyalgia is caused by a problem in how the body processes pain, or more precisely, a hypersensitivity to stimuli that normally are not painful.[] ., fibromyalgia, temporomandibular joint disorder, irritable bowel syndrome, headache and chronic fatigue syndrome) are associated with hypersensitivity to painful stimuli[]

  • Arteriosclerosis

    The inducible form of the heme oxygenase (HO-1) is another example of endogenous anti-inflammatory pathway induced in response to inflammatory stimuli.[] If you have a fainting spell, call your provider right away.[] Consequently, A20-deficient mice fail to terminate TNF-induced NF-κB activity, having a persistently active IKK complex that prevents reaccumulation of IκB protein, are hypersensitive[]

  • Whiplash Injury

    In conclusion, subjects with higher levels of catastrophizing presented with sensory hypersensitivity to cold stimuli in the acute phase of whiplash.[] METHODS: Fifty-two participants with acute whiplash-associated disorders (WAD) ( 30; sensory hypersensitivity) or "low risk" (n 35; without these signs).[] Patients with grade 3 have symptoms of hypersensitivity to a variety of stimuli.[]

  • Migraine

    "People with a genetic predisposition have a reduced threshold for the activation of the brain's 'pain centers' and become hypersensitive to stimuli that cause pain.[] You may have trouble concentrating and also still be hypersensitive to certain stimuli. (32) There’s no single test that can lead to a diagnosis of migraine.[] It may be accompanied by nausea and vomiting as well as blurred vision and sensitivity to certain stimuli.[]

  • Chronic Fatigue Syndrome

    The presence of ongoing or fluctuating flu-like symptoms, arthralgias, myalgias, autonomic disturbances, and a striking hypersensitivity to stimuli in many patients with this[] It is unclear whether the myalgia and arthralgia reflect a general hypersensitivity to all sensory stimuli but both need to be present for more than half of the waking time[] […] to non-target stimuli might be associated with hypersensitivity [ 19 ].[]
