We are soaked in microbiota, both, externally and internally. The balance between harmful and beneficial keeps us healthy, however even slight imbalance in their ratio may make cause of ill health. Many of the species of Lactobacillus keeps the vagina healthy; even some species of Lactobacillus are troublesome to the vagina. Other pathogenic bacteria and fungus cause many diseases. Lactobacillus spp prevents harmful bacteria to infect the vagina; nevertheless their population varies due to various factors mentioned in the text. Because of this the woman suffers even with infertility, abortions etc.

Some of the causes of female infertility were work out in details however now we have understood the unexplained cause of infertility and that is the presence of microbiota in female reproductive tract. Like imbalance of gut microbiota causes health hazards in Hidden Reasons of Woman's Infertility: Microbiota Milieu

Microbiota is a life line for human being, however if the balance in interspecies of microbiota is disturb, it can cause not only serious diseases but can kill also. Collectively the microbiotal species act as epigenetic factor for humans. First exposure to microbiota is in utero. The whole health programming of the individuals stars even before birth. C-section or fed formula fed babies are immunologically weaker than that of normal delivered and beast fed babies. For the lifelong good health of babies, Mothers should opt for vaginal delivery and breastfeeding for healthy newborn

In the human body, practically all organs work in coordination in co-operation with other organs since they are regulated by neurological, hormonal, environmental signals. Scientists have lately found out another regulatory factor the intestinal microbiota. The quality and the quantity of microbiota are also dependent on many internal and external factors. The composition of the intestinal microbiota also affects those systems which are regulated by circadian rhythms, in other words, circadian rhythms and microbiota is a two-way street. In this review, we have discussed the cross-talk between these two regulators.

Short and Intermittent fasting brings many structural and functional changes in the GI tract.Now it has been shown that changes are beneficial in terms of postponing the onset of NCDs prolonging the healthage,That might be the reason for Ancient Indian saints todo fasting. These benefits have been described in a series of research papers by us and others. Change in microbiota due to fasting is a recent addition which explains the mechanism of many physiological processes taking place during fasting.Two other parameters namely, effect of long and short term fasting and.sexual dimorphism on microbiota also dealt with in this review.
