If left untreated, it can lead to progressive health issues, including visual impairment and increased susceptibility to infections.<\/p>\n<h2><strong>Vitamin A Deficiency Symptoms<\/strong><\/h2>\n<p>\u00a0<\/p>\n<p>Symptoms often appear gradually and may vary in severity.<\/p>\n<h3>Early Signs<\/h3>\n<ul>\n<li>Difficulty seeing in dim light<\/li>\n<li>Dry eyes or
