Altitude: Research shows that over 47% of individuals living at high altitudes exhibit spoon nails, with even higher prevalence among those engaged in manual labor.
Rural Environments: Spoon nails were observed in 32% of children living in rural areas, compared to 17% in urban children, likely due to greater foot trauma from walking barefoot.
Occupational Risks: Professions such as hairdressing, involving frequent exposure to petroleum-based hair products, may increase the risk of developing spoon nails.
Diagnosis and Evaluation
If you notice spoon nails or related symptoms, it is important to seek medical advice. Diagnosis may involve:
A physical examination of the nails.
Blood tests to assess for anemia or vitamin deficiencies.
Imaging studies or additional tests if an underlying systemic condition is suspected.
Treatment
Management of spoon nails primarily involves treating the underlying cause:
Iron Supplements: Used to correct iron deficiency anemia.
Dietary Improvements: Enhancing nutrient intake through a balanced diet.
Treatment of Underlying Conditions: Managing diseases such as lupus, thyroid disorders, or heart disease.
Protective Measures: Preventing nail trauma and reducing exposure to harsh chemicals.
Pitted Nails: What They Indicate

Dr. Shah explains that small indentations or pits on the nail surface are commonly observed in individuals with skin conditions such as psoriasis, eczema, and alopecia areata—a form of patchy hair loss. These nail changes are usually accompanied by other visible symptoms; for instance, psoriasis often presents with dry, scaly skin patches, eczema causes dry, itchy, cracked, and sore skin, and alopecia areata is characterized by localized hair loss.
A dermatologist can determine the underlying cause of these nail indentations. In mild cases where the pitting is asymptomatic, treatment is typically unnecessary. However, some cases may benefit from topical or injected corticosteroids and vitamin D3, usually administered in conjunction with therapies targeting the underlying skin disorder.
What Is Nail Pitting?
Nail pitting describes the presence of shallow or deep indentations on the surface of the nails, which can affect both fingernails and toenails. These pits often look like small white spots or marks.
Symptoms of Nail Pitting
Nail pitting is frequently accompanied by other nail changes, especially when associated with nail psoriasis, including:
Alterations in nail shape or deformities
Thickening of the nails
Discoloration of the nails
Nails becoming loose and separating from the nail bed (onycholysis)
In severe cases, nails may become brittle and crumble
Psoriasis-related symptoms may also be present with or without skin involvement, such as:
Scaly, discolored patches on the skin
Dry, cracked, or bleeding skin
Itching or burning sensations
Stiffness or swelling in the joints
Causes of Nail Pitting
Dermatitis: Including atopic and contact dermatitis.
Psoriasis: Nail changes affect up to half of individuals with psoriasis.
Connective Tissue Disorders: Such as Reiter’s syndrome and osteoarthritis.
Autoimmune Diseases: Including alopecia areata, sarcoidosis, and pemphigus vulgaris.
Genetic Disorders: For example, incontinentia pigmenti.
Melanoma and Your Skin: Key Information
Source: Dermnet New Zealand
Many people recognize that cancer can manifest as unusual spots on the skin; however, melanoma—the most aggressive form of skin cancer—can also develop on the fingernails or toenails. If you observe a dark streak running down a nail, it is advisable to consult a dermatologist. While such a dark line is not always indicative of cancer, timely evaluation is important because melanoma is more treatable when detected early.
Although skin cancer is commonly associated with exposed areas, it can also occur beneath and around the nails. Nail melanoma is a rare but highly serious type of nail cancer. It is more frequently seen in older adults, individuals with darker skin tones, and those with a personal or family history of melanoma.
Early Detection and Treatment
Nail melanoma is frequently diagnosed at a later stage, which increases its severity and risks. It is important to regularly examine your nails and seek consultation with a dermatologist if you observe any unusual or suspicious changes. Early identification of melanoma greatly enhances the chances of successful treatment.
Signs to Watch For
When examining your nails for potential melanoma, be alert to these indicators:
Dark Streak: A brown or black stripe running along the nail, often appearing on the thumb or big toe.
Darkened Skin Around the Nail: The skin surrounding the nail may darken, which can signal advanced melanoma.
Nail Lifting: The nail may start to separate from the nail bed.
Nail Splitting: A vertical crack or split down the center of the nail.
Bump or Nodule: A raised area or an irregularly colored band on the nail.
Terry’s Nails: An Overview of the Condition
source: Hojasmuertas
Terry’s nails, named after the physician who first identified the condition, are characterized by whitening of more than two-thirds of the nail bed, leaving a narrow red or pink band at the tip. According to Dr. Shah, this nail change is often an indicator of liver disease. Other associated symptoms of liver disease may include fatigue, jaundice (yellowing of the skin), and loss of appetite. However, Terry’s nails can also appear as a normal part of aging or may signal other serious health issues such as heart disease and diabetes.
Terry’s nails are identified by a predominantly white appearance of the nail, with a thin red or brown band at the tip. The nails typically have a unique, frosted-glass-like appearance.
Although Terry’s nails usually affect all the fingernails, they may also be present on just one nail or on the toenails.
Causes of Terry’s Nails
Terry’s nails are believed to occur due to a reduction in the number of blood vessels and an increase in connective tissue beneath the nail bed, which results in the characteristic whitish coloration of the nails.
Common Underlying Conditions Associated with Terry’s Nails
Terry’s nails are frequently linked to various medical conditions, including:
Liver disease, particularly cirrhosis
Peripheral vascular disease
Chronic kidney failure
Type 2 diabetes
HIV infection
Congestive heart failure
Certain skin disorders, such as vitiligo and tuberculoid leprosy
Viral hepatitis
In addition, Terry’s nails may also develop naturally as part of the aging process, even in the absence of underlying illness.
Treatment for Terry’s Nails
There is no direct treatment for Terry’s nails. Improvement in the appearance of the nails usually occurs by effectively managing the underlying medical condition responsible for the changes.
Terry’s Nails vs. Lindsay’s Nails
Both conditions involve changes in nail color that reflect underlying health problems:
Terry’s Nails: Characterized by predominantly white nails with a narrow red or brown band at the tip.
Lindsay’s Nails: Also known as “half-and-half” nails, featuring a white base and a distinct brownish-red tip.
Lindsay’s nails are most commonly associated with chronic kidney disease. The pale portion is due to chronic anemia, while the darker tip results from increased melanin production.
What Do Yellow Nails Mean?

Yellow Nails: Causes and Treatment
Yellow nails can result from various factors, with fungal infection being the most common cause. Such infections may cause the nail bed to retract, while the nails become thickened and brittle. Although treatment can take time, the condition is generally painless. In rare cases, yellow nails may indicate underlying health issues such as diabetes, psoriasis, thyroid disorders, or lung disease.
Treatment Approaches for Yellow Nails
Management of yellow nails depends on identifying and addressing the root cause. Most instances of discoloration are due to fungal infections or frequent exposure to certain chemicals or products. Home remedies can help in these cases, but their effectiveness is not guaranteed. Persistent nail discoloration should prompt consultation with a healthcare professional for proper diagnosis and treatment.
