What causes itching in the genital area during menstruation?

Some women experience itching in the genital area during menstruation. Because this is a private and sensitive time, scratching is often inconvenient or inappropriate—causing significant discomfort. So, what causes vaginal itching during menstruation?

What Causes Vaginal Itching During Menstruation?

Vulvar itching during menstruation may stem from one of the following two common causes: 1. Vaginitis: Women with pre-existing fungal (e.g., candidiasis) or bacterial vaginosis may experience symptom flare-ups during menstruation due to lowered immune resistance. 2. Allergic reaction: Some sanitary pads—or even certain types of underwear—may trigger allergic reactions in sensitive individuals. Allergy to sanitary pads can cause localized rashes and subsequent itching. In such cases, it is advisable to change pads regularly and consider switching to a different brand.

Menstruation is a normal physiological process in women, characterized by endometrial shedding and bleeding under the influence of estrogen secreted by the ovaries. Immune function tends to decline during menstruation; therefore, women should avoid catching colds and refrain from consuming raw, cold, or spicy/irritating foods. Heavy physical labor and intense exercise should also be avoided, as these may increase menstrual flow and prolong the duration of menstruation. Personal hygiene must be carefully maintained during this time—sexual intercourse and tub bathing are strictly prohibited.

When vulvar itching is pronounced, vaginitis is often the underlying cause. Prompt gynecological examination is recommended to identify the specific type of vaginitis and initiate appropriate treatment. We hope this information has been helpful!
