Regularity is central to our well-being. Everything starts in the gut, and if we can have our gut functioning well, we generally feel better. People who have ongoing gut issues often have worse performance when it comes to their ability to function optimally at home, at work, etc.
If the gut is working normally, then often many other parts of the body work normally as well. As an example, if the gut is having problems, it can have an effect on the central nervous system via the gut-brain axis, which may contribute to difficulties concentrating and mood changes, etc.
