Emergency warning: If you have severe vaginal or lower abdominal pain, high fever, foul-smelling green or yellow discharge, vaginal bleeding, fainting, or severe dizziness, go to the emergency department immediately or call your local emergency health line. General information: Fasting is not a primary factor that directly causes fungus to “multiply.” However, factors that can occur during the fasting day—dehydration, hunger, blood sugar fluctuations, stress, warm/moist conditions, and local irritation—can make symptoms (burning, itching, pain) more noticeable. Local treatments such as suppositories or ovules may cause mild burning or discomfort during the first days of use; this can affect adherence for some people. Practical guidance: If you plan to continue fasting, consult your healthcare professional or pharmacist before making any changes to treatment or fasting practices. For religious rulings, ask a trusted religious authority. Low‑risk measures that may help reduce mild symptoms: drink enough fluids at suhoor and iftar (non‑fasting hours), wear breathable cotton underwear, change wet or sweaty clothing promptly, avoid perfumed soaps and vaginal douches, and limit sugary, highly refined foods. Seek medical evaluation if symptoms significantly worsen or new concerning signs appear.
