what is a yeast infection caused by

A yeast infection is usually caused by an overgrowth of a fungus called Candida , most often Candida albicans. It can happen when the normal balance of bacteria and yeast in the body gets disrupted, such as after antibiotics, during pregnancy, with uncontrolled diabetes, or in warm, moist, irritated areas.

Common causes

• Antibiotics that reduce helpful bacteria.

• Hormonal changes, including pregnancy or around the menstrual cycle.

• Warm, humid conditions or tight, synthetic clothing.

• A weakened immune system or uncontrolled diabetes.

Typical symptoms

• Itching or irritation.
• Burning, soreness, or redness.
• Thick, white, usually odorless discharge in vaginal yeast infections.

When to get checked

If symptoms are severe, keep coming back, or could be caused by something else, it’s best to get a medical diagnosis since other infections can look similar.
