Synopsis: Information regarding fingernail condition, including shape, nail color, and pitting, spoon nails plus vertical and horizontal fingernail ridges. Vertical fingernail ridges (Lengthwise grooves or ridges) may indicate a kidney disorder (kidney failure); associated with aging or iron deficiency (Anemia). It may mean a tendency to develop arthritis. Paronychia (felon) is inflammation of the nail folds, which appear red, swollen, and tender. The cuticle may not be visible. Causes: fungal infection, secondary bacterial infection, people whose hands are often in water are more susceptible.
- Nail (Anatomy)
- In anatomy, a nail is defined as a horn-like envelope covering the tips of the fingers and toes in humans, most non-human primates, and a few other mammals. Fingernails and toenails are made of a tough protective protein called alpha-keratin, a polymer. Alpha-keratin is found in the hooves, claws, and horns of vertebrates. The nail functions by protecting the digits and contributing to tactile sensation.
Your Fingernail condition, shape, and color can often alert you to underlying health problems. Common conditions include nail color changes, pitting, spoon nails, as well as vertical and horizontal fingernail ridges.
- Nail pitting
Small depressions in the nails are common in people with psoriasis - a skin condition that produces scaly patches. They may also result from nail injuries. Pitting may cause your nails to crumble. Pitting is also associated with conditions that can damage your nail's cuticle, such as chronic dermatitis of your fingers or alopecia areata, an autoimmune disease that causes hair loss.
- Fingernail Ridges
Ridges can signify a possible infection such as the flu.
- Vertical ridges

- Nail clubbing
Clubbing occurs when the tips of your fingers enlarge and your nails curve around your fingertips. This condition results from low oxygen levels in your blood and could be a sign of lung disease. Clubbing is also associated with inflammatory bowel disease and liver disease.

- Spoon nails
Spoon nails (koilonychia) are soft nails that look scooped out. The depression usually is large enough to hold a drop of liquid. Spoon nails may be a sign of iron deficiency anemia.
- Mee's lines
Transverse white lines run across the nail, following the shape of the nail moon. Can occur after acute or severe illness, Arsenic poisoning.
- Absent half-moons

- Terry's nails

- Beau's lines
