A lot of things might cause irritated skin. Immune system diseases, medicines, and infections are among them. Allergic skin reactions occur when an allergen is responsible for eliciting an immune system reaction.
Having itchy, red, bumpy skin is aggravating, uncomfortable, and humiliating. Rashes can be caused by many factors, including contact with specific plants (such as poison ivy), as well as allergic reactions to medications or foods. An infection like measles or chickenpox can also produce rashes. Two of the most frequent skin rashes are eczema and hives, both of which are caused by allergies. An allergist can identify and treat your skin disease caused by an allergy, allowing you to live life to the fullest.
Eczema is the most common skin disorder, particularly among youngsters. It affects one out of every five infants but only about one out of every fifty adults. It's currently understood to be caused by the skin barrier's "leakiness," which leads it to dry out and get irritated and inflamed by various environmental conditions. In addition, some young children with eczema have a dietary sensitivity, which can aggravate the condition. The condition is caused by the inheritance of a defective gene in the skin called filaggrin in around half of the patients with severe atopic dermatitis. Because the itch of eczema is not only produced by histamine, unlike hives (urticaria), antihistamines may not be effective in controlling the symptoms. Asthma, hay fever (allergic rhinitis), and food allergies are frequently associated with eczema. The atopic march is the name given to this sequence of events.
Between ten and twenty percent of children and one to three percent of adults suffer from eczema. Eczema is characterized by dry, red, irritated, and itchy skin. Small, fluid-filled lumps on the skin, especially when infected, may exude a clear or yellowish liquid. Eczema sufferers frequently have a family history of allergies.
Hives are a type of skin irritation caused by the immune system's production of histamine. This causes small blood vessels to leak, resulting in skin edema that appears as red pimples or welts.
Urticaria is divided into two types: acute and chronic.
When your skin comes into direct contact with an irritant or allergen, allergic contact dermatitis develops. If you have a nickel allergy and come into touch with jewelry that contains even a trace amount of nickel, your skin may become red, bumpy, scaly, itchy, or swollen at the place of contact. A rash, blisters, itching, and burning are some of the symptoms.
Poison ivy, poison oak, and poison sumac can all produce allergic contact dermatitis if you come into touch with them. An oily coating that covers these plants causes a red, itching rash. Touching them or touching clothing, dogs, or even gardening tools that have come into contact with the oil can cause an allergic reaction.
Contact dermatitis can be caused by soaps, laundry detergents, fabric softeners, shampoos, or even excessive water exposure. Metals (such as nickel, a component of stainless steel and other alloys used to produce costume jewelry), adhesives, nail polish, topical treatments, plants, and latex gloves can also induce a reaction.
It's possible that an allergen won't trigger a skin reaction unless it's also exposed to sunshine. Photoallergic contact dermatitis is the name for this disorder. Shaving lotion, sunscreen, and various perfumes are examples of things that can cause this.
Angioedema is the swelling of the deep layers of the skin. It is frequently encountered in conjunction with urticaria (hives). Angioedema commonly affects soft tissues like the eyelids, lips, and genitals. When angioedema occurs for a brief period of time, such as minutes to hours, it is referred to as "acute." An allergic reaction to drugs or foods is the most common cause of acute angioedema. Chronic recurrent angioedema occurs when the illness repeatedly occurs throughout time. Often there is no identifiable cause.
Angioedema is a type of angioedema that is passed down through the generations. Hereditary angioedema (HAE) is a rare but deadly genetic disorder characterized by swelling in the hands, feet, face, intestinal wall, and airways. It is necessary to visit a specialist because it does not react to antihistamines or adrenaline treatment.
An allergist/immunologist, a physician with specific training and expertise to accurately diagnose your disease, give relief for your symptoms, treat and manage skin conditions as one of the most frequent types of allergies.
