Patients with vaginitis can drink milk in moderation and it will not affect the progression of the disease. In clinical practice vaginitis is a common gynecological disease caused by pathogenic infections and also associated with external stimuli and changes in hormone levels. Common types of vaginitis include trichomoniasis, vulvovaginal pseudomonal yeast disease, bacterial vaginitis, and atrophic vaginitis, which are usually treated with drugs such as metronidazole, tinidazole, and fluconazole. Drinking milk does not affect the effect of the drugs and does not cause the disease to worsen, so patients need not worry too much. It is easy to digest and absorb, and it can provide sufficient nutrition for the body, so vaginitis patients can drink it to improve their body resistance, which is beneficial to their health. When consuming milk, make sure you drink it within the expiration date, avoid drinking milk on an empty stomach, and heat it properly before drinking so that the cold milk does not enter the gastrointestinal tract and cause stomach cramps, leading to diarrhea and abdominal pain. The diet should be as light and nutritious as possible, reduce the intake of cold, spicy and stimulating foods, pay attention to personal hygiene in daily life, and change underwear regularly.
