Doctors say your nails could be warning you about your health problems — here’s what to watch

Your nails are more than just an aesthetic feature, they can offer significant insights into your overall well-being. “Your nail health is a very good reflection of your overall health,” cites dermatologist Christine Poblete-Lopez, MD. “Many things can occur in the nails that can signify systemic or skin problems.”

Sudden variations in or around your fingernails and toenails like changes in color, texture, or shape, may signify issues such as fungal infections, vitamin deficiencies, arthritis, psoriasis, or melanoma. Healthy nails normally have a smooth, shiny texture with a pink nail, b surface but abnormalities may be there.

Common Nail Concerns and What They Mean

Nail Fungus

Yellow toenails may suggest a fungal infection. With time, nails can thicken and form white spots (leukonychia) or streaks. Cuts or cracks in the toe is an entry part for fungi, and though less frequent, fingernails can also be impacted.

Nail Infection

Bacteria can enter via cuts in the cuticles or nail folds (paronychia), resulting in inflammation, pain, and swelling. Nails may also have ridges, turn yellow or green, and change to brittle.

Nail Injury

Injuries such as stubbing a toe or wearing tight shoes, can lead to discoloration (purple, red, brown, or black) called a subungual hematoma. Wounded nails may get thicken with time in regard to repeated trauma (onychogryphosis) and may result into ingrown nails or white spots.

Moles or Melanoma

Discoloration in lines from cuticle to tip may be suggested as a reason for benign moles or subungual melanomas. Dr. Poblete-Lopez advises consulting a doctor if brown lines impact a single nail or get expanded into the cuticle. Ethnic pigmentation changes are usual in African American and Asian populations and usually impact several nails.

Psoriasis

Psoriasis can result to yellow-red “oil drop” or “salmon patch” discoloration, pitting, Beau’s lines, nail loosening (onycholysis), white spots (leukonychia), black lines (splinter hemorrhages), or redness near the cuticle.

Kidney Disease

Beau’s lines, ridged or spoon-shaped nails, and white streaks can suggest acute or chronic kidney disease or iron-deficiency anemia.

Arthritis, Stress, and Medications

Small cysts around the cuticles may indicate arthritis. Stress can result in horizontal lines, while medications such as chemotherapy or certain antibiotics may darken nails or result in white/yellow bands.

Vitamin Deficiencies

Brittle, thin, or splitting nails may be a cause of deficiencies in iron, zinc, selenium, or vitamin B12. Spoon-shaped nails (koilonychia) signal iron-deficiency anemia often.

Uncommon Conditions

• Yellow Nail Syndrome: Nails seem to look yellow or green, thickened, and may fall off, mainly in people over the age of 50. Symptoms are swelling (lymphedema) and fluid deposit lung tissue (pleural effusions).
  
• Darier Disease: A genetic disorder resulting in reddish or broad white nail stripes and V-shaped nicks around the fingertip, often seeen in adolescence.
  
  

Caring for Your Nails

Preventing nail complications isn’t always possible, but you can aid nail health by:

• Being hydrated
  
• Having a balanced diet
  
• Ensuring enough intake of vitamin B and zinc
  

Many nail variations are normal, but continuous or concerning changes should be examined.

“Anything that doesn’t look normal ought to be addressed,” states Dr. Poblete-Lopez. “Your best course of action is to see a doctor as soon as possible.”

FAQs:

Q1. Why do my nails change color?
Nail discoloration can be caused from infections, trauma, or underlying health concerns such as liver or kidney diseases. It’s essential to examine changes and consult a physician if persistent.

Q2. What results in brittle or splitting nails?
Brittle nails may signal vitamin deficiencies, dehydration, or frequent exposure to harsh chemicals. Adequate nutrition and nail care can help strengthen them.
