Is allergic dermatitis contagious?
Allergic dermatitis is a common skin disease, which is an inflammatory skin disease caused by contact with allergens. So, is allergic dermatitis contagious? It is not contagious. This disease can cause itchy skin, formation of vesicles or papules, redness, or swelling. Once symptoms appear, it is recommended to treat with anti-allergic medication. Also, it is important to avoid contact with allergens again, eat a light diet, and ensure adequate rest.
How to treat eczema dermatitis in pregnant women?
Pregnant women's eczema is a relatively common disease during pregnancy. Eczema is a rash-like change in the skin that occurs after pregnancy. First, we must exclude a pregnancy-specific disease called cholestasis of pregnancy. Cholestasis of pregnancy primarily manifests as skin itching, starting initially in the palms and soles of the feet and can spread to various parts of the body, with abdominal itching being the most severe. It differs from eczema mainly in that eczema usually involves changes in the skin, but the itching from cholestasis of pregnancy does not show obvious changes on the skin surface. If cholestasis of pregnancy is excluded, we can manage the condition based on the dermatologist's advice. For mild cases, some topical medications, such as calamine lotion, can be used without significant effects on the baby. If the eczema is severe or even affects sleep, sedative medications may be used before bedtime, or some oral antihistamines can help treat the condition. (Please follow the doctor's prescription when taking any medication.)
Symptoms of Allergic Dermatitis
Allergic dermatitis is a common skin disease characterized primarily by allergic skin reactions, manifesting as numerous small and large papules on the body, and may also include symptoms of itching. If itching is significant, scratching is likely to occur, which can lead to bleeding, scabbing, and flaking of the small papules. After developing allergic dermatitis, it is crucial to promptly identify the allergen and treat the condition accordingly, avoiding contact with foods that may trigger allergies.
Seborrheic dermatitis causes
The causes of seborrheic dermatitis are multifaceted. Typically, if one does not pay attention to their diet, consuming spicy, irritating, or overly greasy foods can easily lead to the occurrence of seborrheic dermatitis. Seborrheic dermatitis can also occur when there is excessive secretion of male hormones, which leads to overactive sebaceous glands. Additionally, some metabolic disorders and genetic factors are also related to the onset of seborrheic dermatitis. Furthermore, seborrheic dermatitis can be associated with a deficiency in B vitamins, as well as physical and chemical irritants. Frequent scratching of the skin or the use of overly alkaline facial cleansers can promote the occurrence and exacerbation of seborrheic dermatitis. Psychological factors can also lead to the occurrence of seborrheic dermatitis; excessive stress, anxiety, and depression can all trigger the condition.
Is eczema contagious?
Atopic dermatitis, also known as eczema, is a particular type of eczema that overall falls under allergic diseases. It is related to individual allergic constitution, familial inheritance, and allergies to high-protein substances. This disease usually manifests in childhood and symptoms may decrease as one ages. Atopic dermatitis is not contagious; it cannot be spread through contact, sharing clothes, or living together. However, the treatment cycle for this condition is lengthy and challenging. It is crucial to seek proper treatment in the dermatology department of a reputable hospital. Allergy testing can be conducted followed by desensitization or medication treatment specific to the symptoms identified. After recovery, it is important to enhance physical exercise, strengthen immunity, avoid spicy and irritating foods, and refrain from staying up late.
What is seborrheic dermatitis?
Seborrheic dermatitis refers to a type of inflammatory skin disease that occurs in areas where sebum secretion is abundant, including the face, chest, and back. These areas tend to be oilier and are prone to developing erythema and greasy scales. If the seborrheic dermatitis is of the dry type, it may also be accompanied by symptoms of peeling skin. The condition commonly affects individuals with hyperactive sebaceous glands, typically those with oily skin. Some people have combination skin that is also prone to oiliness, making them susceptible to seborheic dermatitis, often due to improper skin care. Dietary habits, frequent late nights, and consuming overly spicy or greasy foods can also lead to the development of seborrheic dermatitis.
Will seborrheic dermatitis recur?
Seborrheic dermatitis is likely to recur. In cases of seborrheic dermatitis, oily skin can easily lead to recurrence. Additionally, an inappropriate diet, often consisting of spicy, irritating food, as well as fried and greasy food, and habitual late nights, can also easily lead to recurrence. Therefore, when seborrheic dermatitis occurs, it’s essential to maintain a light diet, avoiding spicy and irritating foods, and seek treatment under the guidance of a doctor. For topical use, one can choose corticosteroid medications, typically choices include desonide ointment or hydrocortisone butyrate cream. For oral medications, options include Vitamin B6 or a B-complex vitamin. If itching is significant, it might also be necessary to combine treatment with antihistamine medications.
Can cheilitis cause facial dermatitis?
Cheilitis is generally caused by the delicate skin on the lips, which may not tolerate strong external irritations, such as during the dry climate in autumn and winter. Prolonged exposure to these irritations can lead to inflammation. For example, the lips may show signs of redness, swelling, heat, pain, or dryness and peeling with bleeding, causing significant discomfort in the patient's diet and daily life. Cheilitis generally does not cause inflammation of the facial skin. However, when a patient has cheilitis, it is also possible that the face has been irritated by external climatic conditions, leading to facial dermatitis. At this time, it is advised that patients should pay attention to protecting their face, wear a mask when going out, and take good care of their facial protection. Additionally, patients can apply some ointment to the face to effectively alleviate discomfort caused by inflammation.
How to deal with seborrheic dermatitis?
For seborrheic dermatitis, topical application of some corticosteroid medications like desonide ointment or hydrocortisone butyrate cream can be utilized. However, it is important to avoid prolonged, excessive use on the more delicate facial skin. In cases of oozing or erosion, treatments such as boric acid solution or saline can be used for wet compresses. Additionally, for seborrheic dermatitis, one may also choose calcineurin inhibitors like tacrolimus ointment or pimecrolimus cream. If severe itching occurs with seborrheic dermatitis, symptomatic itch relief should be provided, primarily through oral antihistamines such as desloratadine dispersible tablets or cetirizine hydrochloride tablets. Treatment can also include traditional Chinese medicine based on differential diagnosis.
Can seborrheic dermatitis be cured?
Seborrheic dermatitis, also known as seborrheic eczema, is a chronic papular squamous superficial inflammatory skin disease that occurs in areas rich in sebaceous glands such as the head and trunk. The exact causes of the disease are still not completely clear, but it is mainly believed to be related to increased sebum secretion or changes in its chemical composition, and associated with colonization and infection by Malassezia species. Additionally, factors such as mental stress, diet, alcohol consumption, and vitamin B group deficiency can also affect the occurrence and development of this disease to varying extents. Thus, the condition is chronic and can recur repeatedly. Although seborrheic dermatitis can be clinically cured, it is prone to recurrence. Hence, it is important to maintain a regular lifestyle, ensure adequate sleep, limit the intake of polysaccharides and fats, consume more vegetables and fruits, abstain from alcohol and spicy irritant foods, and avoid various mechanical irritations. Using less hot water and strong alkaline soaps for bathing can help reduce the recurrence of seborheic dermatitis.
