What describes the situation occurring in Candidiasis?

Candidiasis is primarily characterized by an imbalance in the normal flora of the body, particularly involving yeast from the Candida species. Under normal circumstances, Candida is present in small amounts along with other microorganisms, such as bacteria. However, various factors such as antibiotic use, hormonal changes, or compromised immune function can disrupt this balance, allowing Candida to overgrow. This overgrowth is what leads to the symptoms associated with candidiasis, such as itching, inflammation, and discomfort in affected areas, especially mucous membranes like in oral thrush or vaginal yeast infections.

The other options pertain to different health issues. Excessive protein intake would not directly relate to the development of candidiasis. Similarly, while high levels of white blood cells might indicate an immune response to various infections, they are not a defining feature of candidiasis itself. Vitamin deficiencies can lead to various health problems, yet they are not specifically tied to the overgrowth of Candida. The fundamental aspect of candidiasis is indeed the disruption of the normal bacterial flora, making the imbalance in normal bacteria the correct description of this situation.
