Age itself isn't typically a limiting factor for laser nail fungus treatment. In fact, this approach can be particularly suitable for older patients because it doesn't involve oral medications that might interact with other prescriptions or stress the liver and kidneys. The laser treatment is non-invasive and doesn't enter the bloodstream, which makes it a safer option for people with multiple health conditions or those taking various medications. That said, the overall health of the patient and the condition of their nails should be evaluated by a professional. Older individuals may have thicker nails or circulation issues that could affect healing time, but these factors don't prevent treatment - they just need to be taken into consideration when developing the treatment plan.
