Beau's lines look like horizontal grooves, dents, or ridges that run across the fingernails or toenails, caused by a temporary stop in nail growth from illness, injury, or poor nutrition, appearing as indentations or lines in the nail plate. They can affect one or several nails and may look like a single deep line or several shallower ones, appearing as the nail grows out.
Beau's lines are grooves or dents that run across your fingernails or toenails horizontally.
Causes of Beau's Lines. The transverse grooves on the nail plate that are seen in Beau's lines are caused by a disruption or slowing of cell growth from the nail matrix. Beau's lines are most commonly caused by medications, followed by underlying health conditions, physical trauma, and infection.
Beau's lines are transverse depressions in the nail plate that occur after a stressful event that temporarily interrupts nail formation within the proximal matrix. The precipitating event may be local trauma, chemotherapeutic agents that interrupt cell division, or the abrupt onset of systemic disease.
Beau's lines are horizontal, going across the nailline, and should not be confused with vertical ridges going from the bottom (cuticle) of the nail out to the fingertip. These vertical lines are usually a natural consequence of aging and are harmless.
Cancer: Some types of cancer, including lung cancer and Hodgkin's lymphoma, can cause Beau's lines.
Liver disease can cause distinct nail changes, most notably Terry's nails, where nails appear mostly white with a small pink/reddish band at the tip, lacking the normal half-moon (lunula), resembling "ground glass". Other signs include yellowing, thickening, clubbing (nails curve downwards), leukonychia (white spots/bands), and nail separation (onycholysis). These changes reflect issues with blood flow, low albumin, or connective tissue in the nail bed, often seen with cirrhosis.
Beau's Lines are horizontal grooves that appear on the surface of the nails. Basically, Beau's lines are not a disease but rather a condition, and they are generally harmless. This condition usually indicates an injury to the nail or an underlying medical issue.
Nail changes can show signs of heart problems. It's important to watch for these signs to keep your heart healthy. This helps catch heart issues early. Look out for nail changes like clubbing, splinter hemorrhages, and cyanotic nail beds.
Discolored nails that look yellow or greenish. Thick, dry cuticles that are ragged and tear easily. Redness around the nail (called periungual erythema) Fungal infections — people with autoimmune disorders like Sjögren's are at higher risk for infections.
Nail changes are commonly reported by patients receiving anticancer therapy (approx. 23%); vincristine, hydroxyurea, paclitaxel, etoposide, daunorubicin, bleomycin, cyclophosphamide, dacarbazine and methotrexate have been the commonly implicated drugs.
Thyroid diseases such as hyperthyroidism or hypothyroidism may cause brittle nails or splitting of the nail bed from the nail plate (onycholysis). Severe illness or surgery may cause horizontal depressions in the nails called Beau lines.
Some medical conditions that have been associated with the development of Beau's Lines include: coronary thrombosis, myocarditis, hypopituitarism, hyperthyroidism, gout, diabetes mellitus, hypertension, epilepsy, renal failure, and glomerulonephritis.
Beau's lines of the fingernails appear at 4 weeks of life in 92% of newborns and disappear with growth before 14 weeks. This phenomenon describes a single transverse depression of the fingernails (Fig.
Reduced metabolism affects keratin production, the primary protein in nails, causing them to become brittle. Hypothyroid patients may experience fluid retention, causing nails to separate from the nail bed or form indentations. Brittle Texture: Nails become dry, fragile, and split easily.
Three early warning signs of heart failure include persistent fatigue/weakness, shortness of breath (especially with activity or lying down), and swelling (edema) in your legs, ankles, and feet, often accompanied by rapid weight gain from fluid buildup, all signaling your heart isn't pumping efficiently enough. Other key indicators are a chronic cough (sometimes with pink mucus) and heart palpitations.
Signs Your Nails Are Stressed: Brittleness or peeling edges. Horizontal ridges (Beau's lines) Slower-than-usual nail growth.
Vertical Ridges: These are usually harmless and often become more prominent with age. Horizontal Ridges (Beau's Lines): These can be a sign of more serious issues, such as illness, malnutrition, or trauma to the nail.
Drug-induced true leukonychia (Mees' lines) appears as one or several parallel transverse white bands affecting all nails at the same level and moving distally with nail growth5. Beau's lines are typical signs of acute toxicity to the nail matrix with transient arrest in nail plate production.
If your fingernails change color or you develop horizontal nail ridges, consult your health care provider. These changes could indicate an underlying health condition.
Early signs your liver is struggling often include persistent fatigue, unexplained weight loss, loss of appetite, nausea, abdominal pain/bloating (especially upper right), and itchy skin, with changes in urine/stool color and easy bruising also being key indicators, though sometimes symptoms are absent in early stages. Pay attention to changes like dark urine, pale stools, or jaundice (yellow skin/eyes), as these signal the liver isn't filtering toxins or processing bilirubin properly.
Yellow or opaque coloring. Brittle nails. Pitted nails (can easily break off or fall off) Linear depressions across the fingernail (called Beau's lines)
Pruritus is one of the most common symptoms experienced by patients with cholestatic liver disease. Pruritus associated with cholestasis is characteristically localized to the palms and soles, although generalized itching can also occur.
