Nail Conditions

Lifting of the Nail Plate (Onycholysis)

• Repeated minor injury to the nail underside is the common root cause of the nail plate's lifting—the nail oxides' risen section and changes from pink to white. Concerning skin conditions, this can also be symptomatic for psoriasis, fungal nail infections (onychomycosis) or water immersion.

​

Pitting

• Pitting is while small divots in the nail roughly the size of a pinhead. This is usually associated with other skin conditions such as psoriasis, eczema and alopecia areata (hair loss).

​

Ridging

• Ridging is the vertical or horizontal elevations or depressions in the nail. Vertical ridging is common in older people with repeated nail injury or another condition of lichen planus. Horizontal ridging is caused by interference with the nail bed through biting or picking. It can also appear as a result of episodic paronychia.

​

Thickening of Nail (Onychogryphosis)

• Common in toenails Onychogryphosis is seen in older adults who used long term ill-fitting footwear and/or nail neglect. It is also associated with psoriasis and fungal infections.

​

Discolouration

• Yellow colouring is a result of fungal nail infection (onychomycosis), psoriasis or smoking. In rare conditions, ‘yellow nail syndrome’ can be seen as an underlying disorder affecting the lungs and lymphatics.

• Green nails are usually due to a bacterial nail infection (pseudomonas) or an infection due to a yeast called candida. Pseudomonas infection can often affect nails that a common fungal infection or trauma has damaged.

• Brown colouring can be caused by medications, chemicals from hair dyes, nail varnish, nicotine, trauma, chemotherapy and antibiotics. In rare conditions, melanomas may present as brown or black pigmentation on or under the nail. It is of high importance to seek medical advice to rule out melanoma in the case of a single brown or black nail.

• White (leuconychia) nail colour could be familial or be caused by any medical condition, resulting in low protein levels in the blood.

​

Inflammation of the Nail Fold (Paronychia)

• The nail cuticle's acute infection can cause redness, swelling, tenderness, and pain, in some cases, pus formation. This is commonly a result of over-zealous manicuring or when nails are immersed in water for long periods of time. Occasionally, Paronychia can also be seen in infants who suck their thumbs.
