Yellow nail syndrome
Yellow or green discoloration in your fingernails may result from a respiratory
condition, such as chronic bronchitis, or from swelling of your hands (lymphedema).
In yellow nail syndrome, nails thicken and new growth slows. Nails affected with
this condition may lack a cuticle and may detach from the nail bed in places.
The discoloration occurs because of the slow growth of your nails. Although this
condition is often a sign of respiratory disease, it's possible to have yellow
or green nails and not have a respiratory condition. Yellow or green nails may
also result from any condition that causes the growth of your nails to slow
down.

Pitting
Small depressions in the nails are common in people with psoriasis — a skin
condition that produces scaly patches — or 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.
-------------------------------
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.
-----------------
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
-------------------------
Terry's nails
With the condition known as Terry's nails, your nails look opaque, but the tip
has a dark band.
Sometimes this can be attributed to aging. In other cases, it can be a sign of
serious illness, such as:
Cancer
Congestive heart failure
Diabetes
Liver disease
------------------------------------
Beau's lines
Beau's lines are indentations that run across your nails.
They can appear when growth at the area under your cuticle is interrupted by
injury or severe illness, such as a heart attack. Beau's lines may also be a
sign of malnutrition
---------------------------------
Nail separates from nail bed
With a condition known as onycholysis, your fingernails become loose and can
separate from the nail bed. If your nails show signs of detaching, this may be
associated with:
Injury
Thyroid disease
Fungal disease
Drug reactions
Reactions to nail hardeners or acrylic nails
Psoriasis
------------------------------------
Thickened toenails: What causes them?
Your toenails can thicken for many reasons. These include an injury, skin
conditions such as psoriasis, tight or poorly fitting shoes, and fungal
infections — as shown in this picture.
Among these, a fungal nail infection — onychomycosis (on-i ko-mi-KO-sis)
— is the most common cause of thickened toenails.
