We now know that asthma isn't just a disease of the respiratory system, that it is a syndrome linked with the immune system, nervous system, and even the intestinal system. The latest research now suggest a possible link between asthma and the cardiovascular system.
The study was performed at Northwestern University and published in the December 8, 2015, issue of the Journal of Allergy & Clinical Immunology. It involved a survey of 13,275 children from all 50 states, and showed that those with allergic asthmatics were twice as likely to be diagnosed with high blood pressure and high cholesterol than those without asthma.
It should be known here that most cases of asthma diagnosed in childhood (childhood onset asthma) also involve allergies. It should also be known that about 75 percent of asthmatics overall also have allergies. The asthma subtype involved here is sometimes called allergic asthma or eosinophilic asthma.
It should also be known that both high blood pressure and high cholesterol, (particularly the bad kind of cholesterol), is linked with heart disease. High blood pressure results from arteries that are constricted, and this causes the heart to work hard to push blood through them.
