Patients with bacterial vaginosis are not advised to eat spicy and acidic foods, not to drink alcohol, and preferably not to eat seafood, in order to avoid the recurrence of anaerobic infections that can cause bacterial vaginosis. It is also recommended to insert lactobacillus capsules into the vagina for treatment after the symptoms have completely disappeared and the laboratory tests have turned to (-). Lactobacillus capsules are mainly used to mediate the normal vaginal flora and improve the local resistance of the vagina so that the anaerobic infection will not recur.
