Vaginal odor is a common concern among women,1leading many to seek understanding and solutions for this delicate issue. A healthy vagina has a natural scent that can vary throughout the menstrual cycle.2 However, changes in vaginal odor can signal different health conditions, requiring a deeper understanding of the causes and remedies.2
Key Learnings
- It is normal for healthy women to have some vaginal odor1,2
- Unpleasant and strong odors, especially when accompanied by other signs and symptoms (such as discharge) indicate there may be an infection2
- Personal intimate hygiene is key to keeping unpleasant vaginal odors away, and making sure the right treatment is applied, can help resolve unwanted symptoms2,4
What Causes Vaginal Odor?
The vagina is a finely balanced ecosystem,3 and vaginal odor can be influenced by various factors such as pH fluctuations, natural elements within vaginal fluids, or the microbial balance within.1,2
It is natural for the vaginal fluids to have a scent.2 It may even be normal to have vaginal fluids with smells you don’t find particularly pleasant, as there are elements in vaginal fluids known to be malodorous.1
There are different types of bacteria that live within the vagina.2 When there is a healthy balance of good bacteria the pH is slightly acidic, which helps protect against infections.2,3 Minor shifts in vaginal pH and total amount of vaginal fluids throughout the menstrual cycle are normal and can cause a shift in vaginal smell.2,3
Normal Vaginal Odors
There are some vaginal smells that can shift throughout the menstrual cycle that are not usually a cause for concern.2 Throughout the menstrual cycle, pH levels can vary naturally, and this can cause changes to the vaginal smells. At times, the smell may be slightly bittersweet or even smell slightly sour.2 A mild sour scent can indicate higher levels of acidity, which is linked to the growth of beneficial bacteria (known as Lactobacilli).2 Other smells can occur from traces of urine or sweat in the vaginal area.2 Finally, some women may even notice change in scent of their vaginal discharge when they eat certain foods.2
Abnormal Vaginal Odors
Even though it is normal for vaginal smells to change throughout the menstrual cycle, vaginal odors that are very strong and smell really bad likely mean that there is something wrong, especially if the strong vaginal smell is coming with other symptoms like itching, burning, and a change in the color of the vaginal discharge.2 Here are some examples of bad vaginal smells you should watch out for:2-4
- Fishy vaginal odor could indicate trichomoniasis or bacterial vaginosis
- Rotten fish smell can happen if there is a forgotten tampon in the vagina or if other feminine hygiene products are not changed often enough
- Foul-smelling discharge, in rare cases, might indicate cervical or vaginal cancer, or a rectovaginal fistula (an opening between the vagina and rectum)
Prevention and Treatment of Vaginal Odors
Personal intimate hygiene is the best way to keep unwanted smells at bay. It is also recommended to have safe sex, stay hydrated, and wear breathable and light clothing.2 If an unwanted bacterial infection is the cause of your strong and unpleasant vaginal smells, you may need antibacterial treatments to help clear the infection and restore a healthy balance of bacteria.2
