Are allergies asthmas and coughs related?

Asthma and allergies

as far as the relation. allergies tend to triger histamine to be released which can cause swelling, rashes, itching, etc.. the swelling can have the side effect of fluid accumulation from mucus membranes. asthma is a constriction of tiney muscles deep in the lungs, as they constrict it takes more time and force to breath through the smaller tubes. an alergy can cause swelling of the tissue in the upper and lower airways having the same affect as asthma but also fluid accumulation. in a severe alergic reaction you can have constriction of the upper airway. any fluid, swelling, itching, constriction of the airway can cause coughing. as far as an alergy causing or trigering asthma Im not sure.
Keep searching the net for information and help, try sites devoted to asthma and allergies. also go to sites with message boards. you may find other people there that may share signs/symptoms, and find information on some specialists that may be able to help. Im sure the answer and help is out there somewhere. as far as going out west for TB, I have heard of many people with the condition moving to places like Arizona to improve their conditions. make sure it is a warm dry environment with CLEAN air. bakersfield where I live is warm and dry but we also have a high rate of asthma in children due to our poor air quality. But remember if it is an allergy problem the polen and dust flying in the air in these areas can cause problems as well. what ever your sisters underlying cause you should get a high quality air filter for the living space. she is also going to need to understand what things she is allergic to and do her best to avoid those things the best she can. I wish your sister the best and hope you find the right medical professional that can improve her condition.
