Beau's lines are deep grooved lines that run from side to side on the fingernail or toenail. They are often a symptom of serious conditions and may indicate health trouble. They are usually a result of injury, severe illness, or environmental factors. In some cases, they may be a sign of underlying medical conditions such as hypoalbuminemia, peripheral vascular disease, or uncontrolled diabetes. Beau's lines are typically treated by addressing the underlying cause.

What You'll Learn
Beau's lines
In terms of injuries, Beau's lines can be caused by dropping something heavy on a finger or toe, exposure to extreme cold, manicures or artificial nails, or slamming a finger in a door. Chronic conditions that interfere with blood flow to the nail matrix, such as hypothyroidism, peripheral artery disease, and Raynaud's phenomenon, can also lead to Beau's lines. Skin conditions, severe zinc deficiency, and insufficient protein intake have also been linked to Beau's lines.
Emotional stress, such as divorce, the death of a loved one, or job loss, can also play a role in the development of Beau's lines. Additionally, certain illnesses like heart attacks, high fevers, and strep infections can be a factor. The thickness and number of Beau's lines can provide clues about the underlying cause. For example, a single Beau's line on one nail may indicate an injury to a single finger or toe, while Beau's lines on all nails can suggest an illness or stress as the cause.
To treat Beau's lines, it is essential to address the underlying cause. Once the cause is treated, Beau's lines will grow out gradually, which typically takes about six months. Filling your diet with a rich variety of nutrients and, in some cases, supplements can help promote strong and healthy nail growth. If you have concerns or are unsure about the cause of your Beau's lines, it is recommended to consult a healthcare professional for further evaluation and guidance.

Muehrcke's lines
The appearance of Muehrcke's lines can be a marker for low serum albumin levels. In a study published in the BMJ, Dr Robert Muehrcke examined patients with known chronic hypoalbuminemia and healthy volunteers. He found that the presence of multiple transverse white lines was strongly associated with low serum albumin levels, and the severity of the underlying condition was reflected in the appearance of the lines. Additionally, the lines disappeared upon successful treatment, indicating a return to normal albumin levels.
The exact cause of Muehrcke's lines is not fully understood, but one theory suggests that they may be related to swelling in the nail bed, which puts pressure on the underlying blood vessels, causing colour changes. This is supported by the observation that the lines disappear when pressure is applied to the nail, a phenomenon known as 'blanching'. It is important to note that Muehrcke's lines are not caused by injury to the cuticle or nail area and are different from Beau's lines, which are grooved ridges, and Mees' lines, which are associated with arsenic poisoning and metal toxicity.

Mees' lines
It is important to distinguish Mees' lines from other nail conditions, such as Muehrcke lines or leukonychia, which are caused by injury to the nail bed. Mees' lines are single lines that do not fade with pressure and move up as the nail grows, while Muehrcke lines are paired lines that fade with pressure and remain in the same place on the nail.
If you notice Mees' lines on your nails, it is recommended to consult a healthcare professional for further evaluation. A physical examination, review of medications, and tests for possible exposure to toxins may be necessary to determine the underlying cause.
While Mees' lines themselves do not require treatment, addressing the underlying cause is important. For example, in cases of arsenic poisoning, identifying and eliminating the source of exposure is crucial. Mees' lines will eventually grow out as your nails continue to grow, but treating the underlying condition is the primary concern.

Terry's nails
While there is no specific treatment for Terry's nails, addressing the underlying cause can help improve the condition. It is recommended to consult a healthcare provider for evaluation and treatment if you notice any nail abnormalities, as they can be an indicator of certain health issues.
To maintain overall nail health, it is advisable to avoid biting nails or picking at hangnails. Regular cleaning with a soft-bristle nail brush, moisturising nails and cuticles, and wearing rubber gloves when using chemical products can also help keep nails healthy.

Lindsay's nails
Muehrcke's nails, or Muehrcke's lines, present as one or more pale transverse bands extending across the nail, parallel to the lunula. These lines are a form of leukonychia striata, which are changes in the fingernail that may indicate an underlying medical condition. In contrast to Beau's lines, Muehrcke's lines are not grooved and do not have a three-dimensional deformity. They are also distinct from Mees' lines, which are areas of discoloration in the nail plate that move as the nail grows.
Muehrcke's lines are typically associated with hypoalbuminemia, which can be caused by various factors. These lines are found in the vascular bed beneath the nail plate and do not move with nail growth. They disappear when pressure is applied to the nail, blanching the underlying nail bed. This distinguishes them from true leukonychia striata, such as Mees' lines.
In some cases, Lindsay's nails may be related to Muehrcke's lines, as both conditions can indicate underlying health issues. However, further research and medical evaluation are necessary to establish a definitive connection between the two conditions.
If you or someone you know has nails resembling Lindsay's nails, it is important to consult a healthcare professional for proper diagnosis and treatment. They can help determine the underlying cause and provide appropriate medical advice or interventions.

Frequently asked questions
Transverse lines on nails, also known as Beau's lines, are deep grooved lines that run horizontally across the nail. They are often a symptom of a serious condition.
Beau's lines are caused by a temporary cessation of cell division in the nail matrix, which is where the nail begins to emerge from the finger. This can be caused by an infection, injury, trauma, coronary occlusion, hypocalcaemia, or skin disease.
If you notice Beau's lines on your nails, you should consult a doctor as soon as possible. The treatment for Beau's lines focuses on addressing the underlying cause, which may be an indication of a more serious health issue.
Yes, transverse lines on nails can also be indicative of Muehrcke's nails, which are a strong indicator of hypoalbuminemia. These lines are areas of hypopigmentation without palpable ridges and affect the underlying nail bed, not the nail itself.
