Beneficial Effects of Probiotics in Some of the Important Human Disorders: A narrative review

Probiotics were first proposed by Metchnikoff as contributing factors to health. These living microorganisms, which mainly belong to the microflora bacteria of the gastrointestinal tract, can have beneficial effects on human health if consumed in moderation. The most studied probiotics are lactic acid bacteria, which include Lactobacillus and Bifidobacteria. The present study is an overview of some studies conducted on the effects of using probiotics and their possible patterns in the prevention or reduction of certain human diseases and disorders. The available data suggest that probiotics can play a role in improving constipation and liver enzymes level and functions, and have significant effects on rooting and improving the symptoms of Helicobacter pylori. It was concluded that probiotics have positive effects in metabolic syndrome treatment, preventing gestational diabetes, and improving oral health. Since many probiotics are microorganisms familiar to the gastrointestinal tract, if consumed in moderation, there are no side effects for the host. Using them as complementary therapies for some diseases related to the gastrointestinal tract microflora bacteria can be an effective and low-cost approach to alleviating the annoying symptoms of such diseases.
