Detailed answer

Hyperpigmentation, or the darkening of certain areas of the skin, is not commonly seen as a symptom of oral thrush or candidiasis. Oral thrush is a fungal infection caused by Candida species and typically presents as creamy white lesions on the tongue, inner cheeks, or roof of the mouth. Candidiasis can also affect other parts of the body, such as the genital area, nails, or skin folds, but hyperpigmentation is not a typical symptom in these cases either. Hyperpigmentation is more commonly associated with conditions such as melasma, post-inflammatory hyperpigmentation, or certain hormonal imbalances. If you are experiencing hyperpigmentation and are concerned, it is recommended to consult with a dermatologist for accurate diagnosis and appropriate treatment options.
