Allergy to dust can develop due to genetic characteristics, certain diseases of internal organs, environmental factors. It may not appear from the first months of life, but may occur unexpectedly at any age. If you suspect a household Allergy, it is recommended to contact an allergist-immunologist and pass tests.
Dust consists of small particles of various origins, and only some of the particles in its composition can provoke allergic reactions, so an Allergy to home dust can occur in someone who does not have allergic reactions to construction, book, cement and Vice versa. A person who is allergic to coal dust will not necessarily sneeze and cough while fluffing the pillow.
Symptoms
Allergy to construction dust, household dust, and any other is manifested by one of the 5 main symptoms or a combination of them. Regardless of what provoked the symptoms, the symptoms are almost always identical.
Conjunctivitis
Allergic conjunctivitis is provoked by the ingress of an allergen on the mucous membrane and can have a light, medium and severe course. You can distinguish allergic inflammation from simple mechanical irritation by the fact of simultaneous and uniform inflammation of both eyes, which is manifested by the following signs:
hyperemia of the conjunctiva-the capillaries are clearly distinguished, the conjunctiva around them is reddened;
lacrimation – from scanty to constant for several hours;
redness of the eyelids with partial or complete closure of one or both eyes against the background of angioedema (may cause swelling of the entire face).
Exacerbation of the listed symptoms in a room or in conditions of increased dust is an additional diagnostic sign that must be reported to the doctor.
Allergic rhinitis
The disease is manifested by sneezing, rhinorrhea (discharge of clear fluid from the nose) or congestion, itching. At night, the patient’s condition may be relieved due to the natural release of anti-inflammatory hormones at this time of day. Allergy to construction dust or any other may be accompanied by a secondary infection, then the texture and color of the discharge from the nose may change.
Atypical dermatitis
Dust Allergy can also manifest as eczema after local interaction. Typical signs are itching, peeling, the appearance of spots, cracks on the skin, sometimes the formation of ulceration, wet areas. Allergic eczema is usually localized to certain areas. In children under 12 years of age, this is the area of the elbow, knee, wrist joints, face, and lower legs. In adults, manifestations are observed on the hands, the back of the neck, in the upper half of the body, the “decollete” zone.
Addition to these signs
dry skin is also possible
white or red dermography;
cheilitis-inflammation of the lips and skin around it.
Urticaria
As a rule, urticaria is acute when interacting with a large amount of allergen. Three main symptoms related to urticaria:
blisters – red or whitish areas of puffiness of the skin of various sizes, sometimes with redness around, usually with itching; disappear after 24-30 hours, sometimes faster;
swelling due to the merger of large blisters – with or without itching, sometimes with a burning sensation, can be painful, disappears for about 3 days, sometimes faster;
angioneurotic edema.
Edema appears on the face, hands, and less often on other parts of the body. Edema of the larynx, bronchi, and intestines when exposed to dust particles is rare.
An allergic reaction to household, book, coal, or cement dust causes urticaria and angioedema only in very rare cases.
