Let’s Talk About Lactobacillus and Your Microbiome

The word microbiome is a collective term for microorganisms; they may come in the form of bacteria, fungi, viruses, or protozoa. These microorganisms exist in humans, animals, and the environment. In humans, microbiome typically refers to the microorganisms living on our skin and in our gastrointestinal tract, and they play a vital role in our overall health.

Lactobacillus exists within our intestinal lining, vagina, and urinary tract, making it part of our microbiome. These healthy bacteria perform a range of functions to keep us healthy. So, let’s talk about lactobacillus and your microbiome.

What Is Lactobacillus?

Lactobacillus is a type of bacteria which positively affects our health by helping the gut break down food, absorb nutrients, and fight off other organisms which may cause disease and negatively affect our health. Elsewhere in our bodies, lactobacillus maintains the microbial balance by preventing the overgrowth of harmful microbes. In the vagina, a lack of lactobacilli may lead to an overgrowth of other microbes, resulting in bacterial vaginosis (BV), yeast infections, and trichomoniasis. To boost your lactobacillus levels, you can turn to a range of fermented foods which contain prebiotics and probiotics.

Lactobacillus is commonly found in:

  • Certain over the counter medication
  • Yoghurt
  • Miso
  • Kefir
  • Tempeh
  • Cheese
  • Sauerkraut
  • Sour cream
  • Kombucha

How Does Your Microbiome Affect Your Health?

Your microbiome is intricately linked to your overall health. Together these microbes can weigh between 1kg and 2kg. They act as an extra organ, and there are roughly 40 trillion bacterial cells in your bodymore than your human cells.

Most of these microbes are extremely important but others may cause disease, so keeping your microbiome balanced and filled with a diverse range of bacteria is essential. While research is ongoing, scientists have found various links between the microbiome and certain aspects of our health.

Your microbiome may also affect:

  • The production of essential vitamins such as B and K, which support your immune system
  • The regulation of inflammation
  • Mental processes such as memory, learning, and mood
  • Your weight
  • The health of your heart
  • Your risk of diabetes

How Does Your Microbiome Affect Your Baby?

Scientists debate whether the microbiome is formed in utero or after birth, but they know that the mother’s microbiome affects that of the baby. These microbes enter a baby’s system as it passes through the birth canal and potentially in the womb. The mother passes on even more healthy bacteria to the baby with breastfeeding. To this end, maintaining a healthy diet during pregnancy and breastfeeding is beneficial to the baby. A microbiome that lacks diverse bacteria may result in difficulties digesting breast milk and fibre, a weakened immune system, and struggles with brain function.

It is essential to maintain a healthy diet to maintain healthy levels of lactobacillus in your microbiome during pregnancy and breastfeeding. If you are worried about your gut health and microbiome, consult your doctor or gynaecologist on recommended probiotic and prebiotic supplements. Your doctor will advise you on what strains and cultures are best for you and which products are the most efficacious.

OMNI Ultrasound & Gynaecological Care

Condous performs Advanced Endosurgery procedures for women needing intervention for pelvic masses, adnexal pathology, severe endometriosis or hysterectomy. He also runs ‘Hands on’ Live Sheep Laparoscopic Workshops for gynaecologists at Camden Veterinarian School.
Having completed an undergraduate degree with the University of Adelaide, he left Australia in 1993 and moved to London where he completed his training in Obstetrics and Gynaecology. From 2001 to 2003 Condous worked as a Senior Research Fellow at St George’s Hospital, London. At St George’s he set up the Acute Gynaecology Unit, the first in the United Kingdom. It was also during this time that he developed an interest in Early Pregnancy and especially the management of pregnancies of unknown location (PULs). Condous has developed many mathematical models for the prediction of outcome of PULs which have been featured in numerous peer review journals. In 2005, he returned to Australia where he completed his Laparoscopic Fellowship at the Centre for Advanced Reproductive Endosurgery, Royal North Shore, Sydney.

Condous was appointed as a Consultant Gynaecologist and Senior Lecturer at Nepean Hospital in 2006 and soon was made Associate Professor. In 2010, he was made Departmental Head of Obstetrics and Gynaecology at Nepean Hospital. He obtained the MRCOG in 1999 and was made FRANZCOG in 2005. In 2009, he was awarded his Doctorate in Medicine (MD), University of London, for his thesis entitled: “The management of pregnancies of unknown location and the development of new mathematical models to predict outcome”.

Condous has edited three books including the “Handbook of Early Pregnancy Care”, published over 100 papers in international journals and is internationally renowned for his work in Early Pregnancy. He is the Associate Editor for Gynaecologic Obstetric Investigation, which is a European based journal, as well as the Australasian Journal of Ultrasound in Medicine (AJUM). He is on the organising committee and is an invited speaker at the International Society of Ultrasound in Obstetrics and Gynaecology (ISUOG) Scientific meeting in Sydney 2013. His current research interests relate to the management of ectopic pregnancy, 1st trimester growth, PULs and miscarriage and the use of transvaginal ultrasound (in particular sonovaginography, to predict posterior compartment deep infiltrating rectovaginal endometriosis).Condous is also actively involved with post-graduate education including the annual running of the Early Pregnancy and Gynaecological Ultrasound Interactive Courses for Sonologists, Radiologists, Sonographers and Gynaecologists in Australia.
