Normally acid environment is maintained in the vagina. Disturbance of the pH balance serves the ground for the development of pathological microflora and appearance of vaginal irritation. Apart from infections, vaginal itching may result from menopausal symptoms, oncological diseases, allergy and pediculosis pubis (pubic lice). Telling the difference between them, as well as prescribing adequate treatment is only up to the gynecologist, who will need to make all the necessary analysis in advance.
Physiologically, the vagina maintains acid environment (about 4.0 pH). This medium is supported due to the generation of the agents of normal vaginal microflora, namely lactobacilli. This level of acidity prevents excessive growth and development of other microorganisms, providing for maximal comfort in genitalia.
Occurrence of vaginal itching is a pathological symptom, which may be associated with multiple diseases. Pathological discharge, which is able to provoke itching, should be mentioned in the first place. This discharge can have a bad smell and various forms. In the majority of cases, the reason for this discharge is inflammation of lower segments of the genital tract (vaginitis, bacterial vaginosis, cervicitis). Though, sometimes such discharge may be associated with helminths, psychogenetic or hormonal stimulation (for example, intake of certain drugs or diseases of the nervous system).
Besides, itching may be indicative to:
- Oncological diseases;
- Age-determined urogenital atrophy;
- Allergic reaction;
- Pubic lice and scabies;
Various infections, serving the cause for vaginal irritation
All the infectious diseases shout be classified according to their incitant agents: bacteria, fungi or viruses. Let us discuss the most common variants of vaginitis:
Very often, inflammation of the vagina is being caused by the Candida yeast. The signs of this disease include acute vaginal irritation and curdy discharge with a foul odor. This pathology requires rather a long-term treatment, which is, unfortunately, little effective. Apart from essential antifungal medication, immune-enhancing drugs should be applied, since Candidiasis is a veritable indicator for critical decrease of protective resources of the organism.
