Can Stress cause Bacterial Vaginosis?

2 mins to read
Increased psychosocial stress is associated with an increased prevalence of Bacterial Vaginosis. BV occurs due to a flora imbalance in the vagina, that is, too much pathogenic bacteria and not enough “good bacteria”. This balance can be affected by many factors, the body's stress levels being one of them.


We know that prolonged stress can impact our sleep, immunity and general wellbeing,  but you may be surprised to learn that there is a link between stress and bacterial vaginosis (BV).

A study, published in the American Journal of Obstetrics and Gynecology, suggests that increased psychosocial stress is associated with an increased prevalence of BV. 

BV occurs due to a flora imbalance in the vagina, that is, too much pathogenic bacteria and not enough “good bacteria” or Lactobacillus species.

The lack of Lactobacillus species leads to poor protective defences in the vagina and an increase of pH, which favours the growth of “bad” bacteria. Why Lactobacillus balance is disturbed in the first place is believed to be due to a number of factors including hormones, sexual practices, hygiene, smoking, and according to the above study, stress.

Stress is a physical or emotional event that can impact the body and/or the emotional health of an individual. Initially a stressful event triggers the fight-or-flight response and blood is shuttled to the heart, lungs and muscles. At the same time digestion and the immune system slow down. Cortisol, adrenaline and noradrenaline are released by the adrenal glands, to help perform the changes required to deal with stress.

As the stress response is maintained, the body continues to produces high amounts of cortisone, which can lead to disturbed sleep, increased nutrient requirements and a dampened immunity. This stress response, and the resulting lower immunity, can lead the vagina to be more susceptible to flora imbalances.
