When a woman has gynecological inflammation, she usually needs vaginal douching. One should choose the right and safe lotion. Some women who have gynecological inflammation just go to the market and buy some lotions to cleanse. These lotions may have an antiseptic and antibacterial effect, but they may also harm the dominant bacteria like Lactobacillus and lead to vaginal dysbiosis, which can lead to recurring vaginal inflammation. Therefore, women who have vaginitis need to go to the hospital and use the correct lotion to cleanse under the guidance of the doctor for better results. The second thing is to buy a comfortable and safe vaginal douche. The length of vagina varies from one woman to another because of her race and height. If the length of the douche is the same, it may not be suitable. Because if the douche is too long, it may damage the vaginal wall, and if it is too short, the effect is not very good. So women can choose a suitable douche for douching according to their height or the length of their vagina, which is relatively better and will not damage the vagina. Therefore, the douching solution and the douche are crucial in the process of vaginal douching.
