Due to the nature of our nails being exposed to many elements, fungal nail infections, nail splitting, brittle nail syndrome, and bacterial nail infections are relatively common. Several factors can cause different nail diseases such as trauma to the nail, poor circulation, skin diseases, and even other systemic diseases such as iron deficiency, kidney failure, and lung diseases. 

Your nails can often be a mirror of the overall health of your body. Changes in your nails can be due to different systemic diseases. Because of this, speak with your doctor if you notice any changes in your nail’s color, texture, or sensitivity. At MOD Dermatology, our board-certified dermatologists will evaluate the condition of your nails and offer safe and effective treatment for any nail disease such as toenail fungus treatment in Fremont.

The health of your nails can say a lot regarding the overall health of your body. Nail diseases can often point to a deeper condition including anemia, liver disorder, hyperthyroidism, and more. The sooner a professional can evaluate changes in your nails, the easier it will be to treat the underlying issue. Along with treating skin issues, our dermatologists are hair and nail specialists. The most common nail diseases treated at MOD Dermatology include the following:

Nail fungus or onychomycosis:

This common nail infection is often caused by a type of mold called dermatophytes.  The affected area will have patches of white or yellow discoloration along with possible nail thickening and detachment from the nail bed. Those of older age, poor health, experiencing diabetes, or living in a warmer climate are all at higher risk of contracting this nail fungus.

Psoriasis of the nail:

Common signs of psoriasis of the nail include nail pits, discoloration, crumbling nails, separation from the nail bed, and buildup beneath the nail. Treatment from a dermatologist can work to clear the psoriasis and prevent further symptoms. 

Lichen planus of the nail:

This chronic inflammatory disorder can cause riding, thinning, and splitting of the nail plate. It is necessary to seek treatment right away to prevent permanent nail loss. 


Also known as nail separation, this nail disease causes the nail plate to separate from the skin. Whether due to trauma of the nail, a reaction to chemicals, medications, or fungal infections, various treatments can help regrow the nail after it has detached. 


Paronychia is an infection of the tissue folds surrounding the nail. The most common symptoms of this disease include swelling, sensitivity, redness, and pain around the nail. The two types of paronychia are acute and chronic. Your doctor will evaluate the condition and create a customized treatment plan. 

Onychorrhexis, onychoschizia, or brittle nail syndrome:

Onychorrhexis causes vertical ridges and splitting of the nail. This can cause the nails to become brittle and start to break off. While this nail disease is typically harmless, it can cause pain due to having weak nails.

Pseudomonas nail infection:

Most commonly known as chloronychia or green nail syndrome, this nail disease is due to the growth of Pseudomonas aeruginosa under the nail plate. This creates a green discoloration of the nail. This bacterium is prevalent in wet environments such as contact lens solutions, sinks, and sponges.


It is necessary to treat nail diseases as soon as possible so they don’t worsen or affect your quality of life. If you are experiencing a nail fungus infection or other nail disease, call our MOD Dermatology office near Fremont today to schedule a consultation!
