Repeat itch-scratch cycles may lead to skin thickening and darkening.
Possible complications include rashes, eczema, and bacterial infections.
Extremely dry skin can cause cracks and breaks on the skin.
Medications including topical corticosteroids and oral antihistamines can help ease itching.
Secondary infections may result from scratches and skin breakdown.
Topical or oral antibiotics may be necessary for secondarily infected dry skin.
Several home remedies, such as decreasing bathing frequency and lubricating the skin with thick moisturizers after showers, can help control and prevent dry skin.
What is dry skin?
Dry skin is a very common skin condition characterized by a lack of the appropriate amount of water in the most superficial layer of the skin, the epidermis. While dry skin tends to affect males and females equally, older individuals are typically much more prone to dry skin. The skin in elderly individuals tends to have diminished amounts of natural skin oils and lubricants. Areas such as the arms, hands, and particularly lower legs tend to be more affected by dry skin. Dryness of the skin is affected by the amount of water vapor in the surrounding air, the humidity. Dry skin is also known as xeroderma.
Dry skin may be a mild, temporary condition lasting a few days to weeks. Dry skin may also become a more severe, long-term skin problem for some. Symptoms of dry skin include discomfort from skin tightness and itching. In addition, external factors such as weather can affect the severity of skin dryness. For example, cold or dry air and winter weather can worsen dry skin. Individuals whose occupations require more frequent hand-washing and sanitizing may experience dry skin more often. Dry skin may also be a side effect of some medications or a symptom of an underlying medical disorder.
The epidermis is normally composed of fat (lipid) and protein. The lipid portion of the epidermis helps prevent skin dehydration. When the skin's fatty oils are removed, the skin loses its protection and loses moisture more easily. As skin becomes dry, it also may become more sensitive and prone to rashes and skin breakdown. This condition is sometimes referred to as xerosis. Dry skin may be an entirely invisible skin condition, or may cause a fine dry powder-like appearance of the skin. Untreated, dry skin may become irritated and result in a red rash (xerodermatitis).
Simple prevention and treatment measures are very effective in the treatment of dry skin. Basic dry skin prevention steps include avoidance of harsh soaps and chemical cleansers. Treatment generally requires more frequent and regular applications of bland emollients and moisturizers. Untreated, dry skin may result in complications, including rashes, eczema, secondary bacterial infections, cellulitis, and skin discoloration. Fortunately, dry skin is usually mild and can be easily remedied.
The word "rash" means an outbreak of red bumps on the body. The way people use this term, "a rash" can refer to many different skin conditions. The most common of these are scaly patches of skin and red, itchy bumps or patches all over the place.
A skin tag is a small benign growth of skin that projects from the surrounding skin. Skin tags can vary in appearance (smooth, irregular, flesh colored, dark pigment, raised). Skin tags generally do not cause symptoms unless repeatedly irritated. Treatment for skin tag varies depending on the location on the body.
Hypothyroidism is any state in which thyroid hormone production is below normal. Normally, the
rate of thyroid hormone production is controlled by the brain at the pituitary.
Hypothyroidism is a very common condition and the symptoms of hypothyroidism are
often subtle.
Psoriasis is a long-term skin condition that may cause large plaques of red, raised skin, flakes of dry skin, and skin scales. There are several types of psoriasis, including psoriasis vulgaris, guttate psoriasis, inverse psoriasis, and pustular psoriasis. Symptoms vary depending on the type of psoriasis the patient has. Treatment of psoriasis may include creams, lotions, oral medications, injections and infusions of biologics, and light therapy. There is no cure for psoriasis.
Diabetes mellitus is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.
Sjögren's syndrome is an autoimmune disease involving the abnormal production of extra antibodies that attack the glands and connective tissue. Sjögren's syndrome with gland inflammation (resulting dry eyes and mouth, etc.) that is not associated with another connective tissue disease is referred to as primary Sjögren's syndrome. Sjögren's syndrome that is also associated with a connective tissue disease, such as rheumatoid arthritis, systemic lupus erythematosus, or scleroderma, is referred to as secondary Sjögren's syndrome. Though there is no cure for Sjögren's syndrome, the symptoms may be treated by using lubricating eye ointments, drinking plenty of water, humidifying the air, and using glycerin swabs. Medications are also available to treat dry eye and dry mouth.
Athlete's foot (tinea pedis) is a skin infection caused by the ringworm fungus. Symptoms include itching, burning, cracking, peeling, and bleeding feet. Treatment involves keeping the feet dry and clean, wearing shoes that can breathe, and using medicated powders to keep your feet dry.
Hyperthyroidism is an excess of thyroid hormone resulting from an overactive thyroid gland. Symptoms can include increased heart rate, weight
loss, depression, and cognitive slowing. Treatment is by medication, the use of
radioactive iodine, thyroid surgery, or reducing the dose of thyroid hormone.
Itching can be a common problem. Itches can be localized or generalized. There are many causes of itching to include: infection (jock itch, vaginal itch), disease (hyperthyroidism, liver or kidney), reactions to drugs, and skin infestations (pubic or body lice). Treatment for itching varies depending on the cause of the itch.
There are many types of thyroid disease. Some occur due to the function of the thyroid itself such as hypothyroidism, hyperthyroidism, Hashimoto's thyroiditis, etc. Some causes of thyroid disease occur due to problems with the structure of the thyroid gland such as goiters, thyroid nodules, and thyroid cancer. Treatment of thyroid disease depends on the cause of the disease.
Sjögren's syndrome involves inflammation of glands
and other tissues of the body.
About 90% of Sjögren's syndrome patients are female.
Sjögren's syndrome can be complicated by infections
of the eyes, breathing passages, and mouth.
Sjögren's syndrome is typically associated with
antibodies against a variety of body tissues (autoantibodies).
Diagnosis of Sjögren's syndrome can be aided by a
saliva-gland biopsy.
Treatment of patients with Sjögren's syndrome is directed toward the particular areas of the body that are involved and complications, such
as infection.

mouth and eyes. Autoimmune diseases feature the abnormal pr...
