Here's a breakdown of what it is:
* Definition: Onychauxis is a thickening of the nail plate that results in deformities and often an abnormal curve. The nail grows excessively in thickness but not necessarily in length.
* Causes:
* Trauma: Repeated injury to the nail matrix (where the nail grows from) is a common cause. This could be from ill-fitting shoes, sports, or other activities.
* Fungal infections: Fungal infections of the nail (onychomycosis) can lead to thickened and distorted nails.
* Poor circulation: Reduced blood flow to the extremities can affect nail growth and lead to thickening.
* Genetics: In some cases, onychauxis may be inherited.
* Systemic diseases: Certain medical conditions, such as psoriasis, eczema, diabetes, and peripheral vascular disease, can contribute to onychauxis.
* Aging: Nail growth naturally slows and nails can become thicker with age.
* Medications: Some medications can affect nail growth.
* Symptoms:
* Thickened nail plate
* Yellowing or discoloration of the nail
* Distorted nail shape (often curved or ram's horn-shaped)
* Pain or discomfort, especially if the thickened nail presses on the surrounding tissue.
* Brittle or crumbly nails
* Difficulty cutting the nails
* Treatment:
* Trimming and Filing: Regular trimming and filing of the nail to reduce thickness and prevent ingrown nails. A podiatrist can do this if the nail is very thick or difficult to manage.
* Topical antifungal medications: If a fungal infection is present, topical antifungal medications may be prescribed.
* Oral antifungal medications: For more severe fungal infections, oral antifungal medications may be necessary.
* Nail avulsion: In some cases, surgical removal of the nail (nail avulsion) may be recommended. This is often followed by medication to prevent regrowth of a deformed nail.
* Addressing Underlying Conditions: Treatment of any underlying medical conditions that may be contributing to the nail changes.
It's important to consult a doctor or podiatrist if you suspect you have onychauxis, as they can diagnose the cause and recommend the most appropriate treatment.
