Detailed answer

Hyperpigmentation refers to the darkening of the skin due to an overproduction or accumulation of melanin. While fungal infections can cause hyperpigmentation, it is not specific to oral thrush alone. Fungal infections such as tinea versicolor, candidiasis, or pityriasis rosea can lead to hyperpigmentation in various areas of the body, including the skin. However, oral thrush, which is caused by Candida yeast, primarily affects the mouth and does not typically lead to hyperpigmentation. It is important to seek medical advice for a proper diagnosis and treatment plan if you suspect a fungal infection. A dermatologist can examine the affected areas and recommend suitable treatments to address both the infection and hyperpigmentation, if present.
