Infections or Illness: Severe illnesses or infections, including high fever or viral infections like chickenpox or measles, can lead to Beau’s lines as the body temporarily stops nail growth.
Trauma or Injury: Physical injury to the nail, such as trauma to the finger or hand, can cause temporary interruption of nail growth, resulting in horizontal ridges.
Nutrient Deficiencies: Deficiencies in zinc, protein, or biotin can disrupt nail growth, leading to the appearance of Beau’s lines.
Systemic Conditions: Conditions like diabetes, heart disease, thyroid disorders, and malnutrition may be associated with horizontal ridges.
Chemotherapy: Cancer treatments, particularly chemotherapy, can interrupt the growth of nails, causing ridges to form as a side effect.
When to See a Doctor:
If you develop Beau’s lines and they are accompanied by other symptoms like unexplained weight loss, fatigue, or swelling, it’s important to consult a doctor. This could point to an underlying systemic issue that needs attention.
3. Pitting (Small Dents or Holes) on Nails
What It Is:
Pitting refers to small, shallow indentations or depressions that appear on the surface of the nails. It’s more commonly associated with certain skin conditions.
Possible Causes:
Psoriasis: Pitting is a common sign of psoriasis, a chronic autoimmune condition that affects the skin but can also impact nails. The condition may lead to small pits forming in the nails.
Eczema: Another skin condition that can lead to pitting, as eczema can affect the nail matrix (the part of the nail where growth occurs).
Arthritis: Certain types of arthritis, particularly psoriatic arthritis, can also cause pitting in the nails.
When to See a Doctor:
If you notice pitting along with other skin symptoms (like rashes or joint pain), it’s a good idea to see a dermatologist or rheumatologist, as it could be a sign of an autoimmune condition.
