Oncholysis is loosening or detachment of the nail from the nail bed. It starts at the border of the nail and usually affects the ring finger. However, it can occur on any of the fingernails and takes 3-4 months to clear up. As the condition progresses, the affected nail turns yellowish or whitish in colour.

There are numerous causes that might be responsible for oncholysis. They include physical trauma, excessive manicuring, fungal or viral infection, dermatitis, psoriasis, hypothyroidism, arthritis, idiopathic epilepsy and impaired peripheral circulation.

If you have oncholysis, then make sure that you trim the nail short and do not clean under the nail. It also makes a good idea to consume diets that are rich in omega-3 nutrients. Omega-3 fatty acids especially EPA and DHA help maintain the health of skin and nails. The rich dietary sources of omega-3 nutrients include salmon, mackerel, nuts, whole grains and vegetables. You can also consume a dietary supplement on a regular basis that makes use of omega-3 fatty acids in its formulation.
