6. Bluish coloration of the skin
In anaphylaxis, there are a series of changes in the circulatory system, and one of the most common signs is a bluish coloration of the skin, which is clinically named cyanosis. This condition only reflects a lack of oxygen supply to the area and predominance of non-oxygenated blood, which looks bluish through the skin instead of red. These patients have an impaired circulation of peripheral blood, low blood pressure and low levels of oxygen in the blood, which may lead to serious complications when their condition is not attended in the emergency room.
As you have seen, allergies in adults can be quite dangerous or rather mild and difficult to detect. It all depends on the type of allergy, the antigen involved, and the type of hypersensitivity reaction that is triggered. Most cases of allergies in adults are self-limited and can be controlled by oral or topic antiallergic medications, but you should be careful when symptoms of anaphylaxis start to arise. In these cases, do not delay your diagnosis further and go to the emergency room. That is how your individual case will be examined and you will know for sure whether or not you need to worry about these symptoms. Keep in mind that certain allergens are more rapidly progressing than others, as in the case of peanuts and seafood allergies, and if you have encountered this type of allergy you should be very careful with the preparation of your food and inform the personnel in restaurants about your food allergies before ordering.
