Allergies affect a large number of people worldwide. Some allergies can have a negative effect on blood pressure and cholesterol levels, for example, but a possible connection between a reduced risk of cancer and allergy sufferers has also been found.
Increased risk of heart disease from allergies: A study
So far it is not known exactly how allergies can affect other diseases. Researchers are currently discussing whether allergic diseases may promote other diseases or whether they reduce the risk of other diseases. Both approaches provide apparently plausible arguments; Since the immune system reacts very hypersensitively to harmless substances in an allergy, it is possible that allergy sufferers have an extremely strong immune system because it is “stressed” more and thus “trained”. On the other hand, it is being discussed whether the immune system is already so busy dealing with the allergy triggers that other pathogens are no longer optimally combated. Based on this discussion, various studies on the topic.
An exemplary study is that of Northwestern University Feinberg School of Medicine. This examined data from more than 13,000 children with an allergic disease. The research focused on the question of which diseases can promote allergy in children. Atopic eczema, hay fever and allergic asthma firstly had a proven negative effect on the children’s sleep, secondly, a higher blood pressure and higher cholesterol levels to be determined.
The results of the study show that in addition to reduced sleep rest, blood pressure also rises and cholesterol levels are often elevated. Both high blood pressure and elevated blood lipid levels are significant Risk factors for various heart diseases. Particular emphasis is placed on allergic asthma and hay fever, which even double the risk of heart disease. This makes allergies an even greater risk factor for heart disease than obesity, which was previously thought to be the greatest risk. Why the allergy works this way could be due to the high levels of inflammatory substances in the blood that are typical of an allergy. The substances are responsible for activating inflammatory processes in the vessels. This promotes high blood pressure, according to the study leader, Silverberg. In addition, the high blood pressure can be associated with the often reduced movement of asthmatic children in the fresh air. Accordingly, it becomes apparent that allergies are a significant risk factor for heart disease even in childhood. The head of the study demands that the so-called screening, an early detection program for diseases, be carried out in children suffering from an allergic disease carried out early and closely. This is to prevent high blood pressure and high cholesterol from being overlooked.
Study: Cancer linked to allergies
Another study put the focus slightly differently. The goal was one Relationship between cancer and allergy sufferers to manufacture. Researchers at Baylor College of Medicine’s Cancer Center analyzed the health records of 4,500 people with glioma, that is, one brain tumor sick patients, with those of 4,200 healthy people.

Based on the health data, it was discovered that there were fewer cancer patients among allergy sufferers than among people without allergies. The difference was around 30% – the allergy sufferers usually had a respiratory allergy such as hay fever. It could now be assumed that respiratory allergies could reduce the risk of developing cancer. However, it is not (yet) clear why this could be the case.
Also: Whether the result only Coincidence or actual evidence is for a connection can also not yet be said with certainty; so does study leader Melissa Bondy. In this aspect, in the future more data collected and researched so that concrete statements can be made.
It is important to note that the studies only to specific allergies, such as allergic asthma or respiratory allergies. In addition, the first study focused on children, the second on brain tumor patients. The data can not generalized will; the second study presented in particular can still be no confirmed facts deliver.
Nevertheless, both studies are interesting to look at because they incentive for future research can give and represent progress. A more comprehensive study situation can be of help for affected allergy sufferers in the future and provide important information on the possible effects on other diseases.
