Intestinal Microbiota in Early Life: Latest Findings Regarding the Role of Probiotics as a Treatment Approach for...

The gut microbiota plays a crucial role in early-life development, influencing various aspects of health and disease. Dysbiosis, an imbalance in the gut microbiota, has been linked to multiple health conditions, including allergies, asthma, and obesity. In early life, the gut microbiota plays a key role in the development and maturation of the immune system. Probiotics, live microorganisms that confer health benefits when administered in adequate amounts, have emerged as a potential treatment approach for dysbiosis in early life. Dysbiosis can alter the resistance to pathogens, promoting atopic diseases, food sensitization, and infections such as necrotizing enterocolitis (NEC). Probiotics have been shown to modulate the composition and function of the gut microbiota in the perinatal and infant periods. They can increase the abundance of beneficial bacteria, such as Bifidobacteria and Lactobacilli, and reduce the levels of potentially harmful bacteria. Not all probiotics are created equal. The effects of probiotics can vary depending on the specific strain used. Probiotics have also been investigated for their potential benefits in other areas of infant health, such as reducing the risk of respiratory infections and improving growth and development. This review aims to analyze the current data in the literature and to evaluate the health benefits of probiotic administration in early life. Several studies have investigated the use of probiotics in preventing or treating allergic diseases, such as eczema and food allergies. While some studies have shown promising results, more research is needed to fully understand the benefits and risks of probiotics in early life. In conclusion, using probiotics to prevent dysbiosis-related conditions may be considered a method of 'programming' the individual for optimal health maintenance.
