A white patch on the lip can be caused by a variety of reasons, including fungal infections, nutritional deficiencies, and oral mucosal diseases. This condition usually doesn't cause pain, but may be accompanied by mild itching. If the white patch appears after meals or upon waking in the morning, it may be due to poor oral hygiene or dietary habits causing an oral mucosal reaction.
Another possibility is nutritional deficiency, particularly a lack of B vitamins or iron, which can lead to abnormal changes in the oral mucosa. In this case, white patches may recur over a period of time, accompanied by symptoms such as fatigue and difficulty concentrating. If the symptoms continue to enlarge, darken in color, or are accompanied by pain or bleeding, it is necessary to consider whether there is a more serious health problem, such as precancerous lesions of the oral cavity, and in this case, you should seek medical attention immediately for a professional examination.
Patients must know that while white patches on the lips are mostly benign, any unusual changes should be taken seriously. Avoid self-diagnosis and seek professional medical help for a thorough examination promptly. Common misconceptions include believing that white patches are caused by simple oral hygiene problems, while ignoring potential nutritional deficiencies or other health issues.
