What is a common cause of recurrent candidal infections?

Recurrent candidal infections, commonly known as yeast infections, are often associated with conditions that can alter the body's normal flora and immune responses. Diabetes mellitus is one of the most common underlying conditions that can lead to an increased risk of these infections.

In individuals with diabetes, particularly if their blood glucose levels are poorly controlled, glucose can accumulate in various tissues and fluids. Higher levels of glucose in vaginal secretions create an environment favorable for the growth of Candida organisms. Additionally, diabetes may impair immune function, making it more difficult for the body to fight off infections, including those caused by fungi such as Candida.

This connection illustrates why diabetes mellitus is a significant risk factor for recurrent candidal infections. The other options may contribute to health issues but are less directly linked to the frequent occurrence of these fungal infections.
