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.[apps.who.int] 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[kidshealth.org] Pressure Urticaria –Pressure urticaria is a form of hives and wheals that develop in response to physical pressure (similar to dermatographia).[cholinergicurticaria.net]

  • Systemic Mastocytosis

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

  • Hypersensitivity

    […] marked sensitivity/reactivity to innocuous stimuli hypersensitivity An excessive reaction, local or systemic, or inappropriate immune response to an antigen.[medical-dictionary.thefreedictionary.com] 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[ncbi.nlm.nih.gov] […] by the Schiff sensitivity scale/a visual rating scale (VRS) and tactile threshold, respectively], and using the Dentin Hypersensitivity Experience Questionnaire (DHEQ, a[ncbi.nlm.nih.gov]

  • Orthostatic Hypotension

    Individuals with pure autonomic failure have marked hypersensitivity to all pressor and depressor stimuli.[ncbi.nlm.nih.gov] 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[en.wikipedia.org] Water ingestion - -drinking 16 oz of water over 5 minutes can prevent a fainting spell (Lu et al, 2003)..[dizziness-and-balance.com]

  • Syncope

    Stimuli can also include forceful coughing, turning of the neck or wearing a tight collar (carotid sinus hypersensitivity), or urinating (micturition syncope).[www2.gov.bc.ca] 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.[utmc.utoledo.edu] For individuals who have problems with chronic fainting spells, therapy should focus on recognizing the triggers and learning techniques to keep from fainting.[en.wikipedia.org]

  • 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[adaa.org] 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.[web.archive.org] ., fibromyalgia, temporomandibular joint disorder, irritable bowel syndrome, headache and chronic fatigue syndrome) are associated with hypersensitivity to painful stimuli[dx.doi.org]

  • Arteriosclerosis

    The inducible form of the heme oxygenase (HO-1) is another example of endogenous anti-inflammatory pathway induced in response to inflammatory stimuli.[physrev.physiology.org] If you have a fainting spell, call your provider right away.[nlm.nih.gov] 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[physrev.physiology.org]

  • Whiplash Injury

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

  • 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.[prevention.com] 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.[everydayhealth.com] It may be accompanied by nausea and vomiting as well as blurred vision and sensitivity to certain stimuli.[everydayhealth.com]

  • 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[pnas.org] 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[doi.org] […] to non-target stimuli might be associated with hypersensitivity [ 19 ].[doi.org]
