Separation of the nail from the nail bed, medically known as onycholysis, is a common condition that results in a white appearance of the affected part of the nail. Fingernail or toenail separation can have numerous causes but is typically related to trauma or a fungal infection of the nails. Nail separation can sometimes be associated with other abnormalities of the nails, including nail pitting, flaking or crumbling, or other damage to or changes in the nail. Toenail or fingernail separation is generally painless and may occur gradually, without the affected individual being aware of a distinct cause. In some instances, onycholysis can be related to systemic conditions, including connective tissue disorders or hyperthyroidism.
Other causes of nail separation
- Bacterial Infection
- Chemical Dermatitis
- Congenital Abnormalities
- Excessive Exposure to Moisture
- Histiocytosis X
- Reiter Syndrome

Causes of Nail Separation
Amyloidosis is a group of diseases resulting from abnormal deposition of certain proteins (amyloids) in various bodily areas. The amyloid proteins may either be deposited in one particular area of the body (localized amyloidosis) or they may be deposited throughout the body (systemic amyloidosis). There are three types of systemic amyloidosis: primary (AL), secondary (AA), and familial (ATTR). Primary amyloidosis is not associated with any other diseases and is considered a disease entity of its own. Secondary amyloidosis occurs as a result of another illness. Familial Mediterranean Fever is a form of familial (inherited) amyloidosis. Amyloidosis treatment involves treating the underlying illness and correcting organ failure.
Eczema is a general term for many types dermatitis (skin inflammation). Atopic dermatitis is the most common of the many types of eczema. Other types of eczema include: contact eczema, allergic contact eczema, seborrheic eczema, nummular eczema, stasis dermatitis, and dyshidrotic eczema.
Can a Nail Grow Back if Removed?
Yes, nails have good regeneration capacity, but they grow slowly. Fingernails may grow one-tenth of a millimeter each day, so completely removed fingernails usually grow within 6 months. Toenails may grow at about one-half or one-third the rate of the fingernails, so completely removed toenails may grow within 18 months.
Do You Have to Drain a Subungual Hematoma?
A subungual hematoma is bleeding under the nail. A doctor will drain your subungual hematoma only if it causes pain or is greater than 50% of the surface area of your nail. If blood is spontaneously draining from the hematoma, drainage of subungual hematoma is generally not required.
Eczema refers to skin inflammation. There are many different types of eczema that produce symptoms and signs that range from oozing blisters to crusty plaques of skin. Treatment varies depending upon the type of eczema the person has.
Fungal nails (onychomycosis) may be caused by many species of fungi, but the most common is Trichophyton rubrum. Distal subungal onychomycosis starts as a discolored area at the nail's corner and slowly spread toward the cuticle. In proximal subungal onychomycosis, the infection starts at the cuticle and spreads toward the nail tip. Yeast onychomycosis is caused by Candida and may be the most common cause of fungal fingernail.
Hyperthyroidism is an excess of thyroid hormone due to an overactive thyroid gland. Symptoms can include increased heart rate, weight loss, heart palpitations, frequent bowel movements, depression, fatigue, fine or brittle hair, sleep problems, thinning skin, and irregular vaginal bleeding. Graves' disease is the most common cause of hyperthyroidism. Many other health problems or taking excess thyroid hormone medication can cause an overactive thyroid gland. Treatment for the condition is with medication, radioactive iodine, thyroid surgery (rarely), or reducing the dose of thyroid hormone. No diet has been shown to treat hyperthyroidism or its symptoms and signs.
Leprosy (Hansen's disease) is a disfiguring disease caused by infection with Mycobacterium leprae bacteria. The disease is spread from person to person through nasal secretions or droplets. Symptoms and signs of leprosy include numbness, loss of temperature sensation, painless ulcers, eye damage, loss of digits, and facial disfigurement. Leprosy is treated with antibiotics and the dosage and length of time of administration depends upon which form of leprosy the patient has.
Lupus (Systemic Lupus Erythematosus or SLE)
Systemic lupus erythematosus is a condition characterized by chronic inflammation of body tissues caused by autoimmune disease. Lupus can cause disease of the skin, heart, lungs, kidneys, joints, and nervous system. When only the skin is involved, the condition is called discoid lupus. When internal organs are involved, the condition is called systemic lupus erythematosus (SLE).
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.
Sarcoidosis, a disease resulting from chronic inflammation, causes small lumps (granulomas) to develop in a great range of body tissues and can appear in almost any body organ. However, sarcoidosis most often starts in the lungs or lymph nodes.
Scleroderma is an autoimmune disease of the connective tissue. It is characterized by the formation of scar tissue (fibrosis) in the skin and organs of the body, leading to thickness and firmness of involved areas. Scleroderma is also referred to as systemic sclerosis, and the cause is unknown. Treatment of scleroderma is directed toward the individual features that are most troubling to the patient.
Syphilis in Women
Syphilis is a sexually transmitted disease (STD) caused by a spiral-shaped type of bacteria known as a spirochete. There are three stages of syphilis with distinct symptoms. During first stage of syphilis, a painless ulcer known as a chancre forms. Irreversible organ damage can occur during the late stage of syphilis. Special blood tests are used to diagnose syphilis. Syphilis infection is treated with penicillin. Condom use can often prevent syphilis.
Warts (Common Warts)
Common warts are skin growths causes by the human papillomavirus. There are many types of warts, including plantar warts, common hand warts, warts under the nails, mosaic wars, and flat warts. Over-the-counter treatments typically involve the use of salicylic acid products.
