what is the difference between hypersensitivity and autoimmunity?

Very different: A hypersensitivity is generally what we call an allergic reaction. This is mostly to things you find in the environment, and most of the time is driven by an antibody called ige. An autoimmune disease is usually driven by igg antibody, and what is being attacked is something in the body that the immune system thinks is "foreign" and should be "dealt with" when it shouldn't be.

Yes: Hypersensitivity usually means that your immune system reacts to something the majority of people do not. The agent is from the outside world. Autoimmunity means that your immune system is attacking your body's own tissue.

What's the difference between immunodeficiency and autoimmunity?

Dr. Javier Chinen

Function and target: The immune system should react against substances that harm us, and should tolerate substances that do not harm us. In immunodeficiency, there is a weakness on the immune response. Infectious occur frequently and more severe. In autoimmunity, there is malfunction on the immune response, targetting our own tissues, such as our joints in rheumatoid arthritis. Both processes may occur together.

Desensitization: Allergen desensitization does not work on all allergies--it is most effective with seasonal allergens, indoor allergens and insect bites.Insect bites from bees, red ants and wasps are treated with allergen desensitization.Allergen desensitization uses small amounts of the allergen the person is allergic to and injects the allergen into the individual's body.

How do I solve my hypersensitivity to sound? Besides earplugs.

Depends on diagnossi: Do you know why you are hypersensitive to sounds? This could be a neurological issue, it could be due to migraines, it you've had this all your life it could just be congenital. Is it one or both ears. If only one ear, could be something serious, a problem in that side of your auditory system, worse case scenario a tumor. Unlikely, but see your dr. To rule out something serious but treatable!

Sound hypersentivity: Too broad question. Cause of sensitivity? Treat the cause! trauma psychological or physical can trigger hyper response to stimuli , even though sound might not have been part of the trauma. Part of hyperarousal, state of hyper stimulation, easily startled...Treat the cause. If cause not found or not remembered (child trauma-abuses), specialists can still help find cause by different modalities.

What is the difference between autoimmunity and polymyalgia rheumatica?

See below: Pmr is an auto immune disease. In auto immune diseases certain types of white blood cells attack your own tissues and cause cell or tissue destruction. Lupus and rheumatoid arthritis are two common examples. In these cases the immune system must be modulated, sometimes with powerful medications.
