Gut Health Test Guide: What It Reveals & How It Helps
Your gut plays a crucial role in digestion, immune function, and overall well-being.
An imbalance in gut bacteria can lead to digestive issues, food intolerances, and even chronic health conditions.
A gut health test analyzes your microbiome, helping to identify imbalances, potential infections, and dietary adjustments needed for optimal gut function.
Understanding what a gut health test reveals and how it can benefit you is essential for improving digestion, boosting immunity, and enhancing overall wellness.
This guide explains the different types of gut tests, what they detect, and how the results can help you make informed health decisions.
