Your Digestive System and How It Works

An evidence based overview of how your digestive system works, from the NIDDK, and why gut health is foundational to overall wellness.

About This Resource

Understanding how your digestive system works is a foundational step in a root cause approach to health. This resource draws from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) to explain digestive function in clear, accessible terms.

Why We Share It

At Nepute Wellness, gut health is one of the first areas we assess because it influences far more than just digestion. This resource helps you understand the foundation that makes gut health so important.

Why Gut Health Is Foundational

At Nepute Wellness, gut health is one of the first areas we assess. Research consistently demonstrates that the digestive system influences far more than just digestion: it affects immune function, mental health through the gut brain axis, nutrient absorption, hormone balance, and inflammation throughout the body.

The NIDDK provides excellent foundational information about how the digestive system works, and we share this resource because understanding the basics helps you understand why we take gut health so seriously.

How Digestion Works

Digestion begins in the mouth and involves a coordinated process through the esophagus, stomach, small intestine, large intestine, and supporting organs (liver, pancreas, gallbladder). Each stage serves a specific purpose in breaking down food, absorbing nutrients, and eliminating waste.

The small intestine is where most nutrient absorption occurs. This is also where the gut microbiome is most concentrated and where disruptions may have the greatest impact on overall health.

The Root Cause Connection

Many patients come to Nepute Wellness with symptoms that seem unrelated to digestion: fatigue, brain fog, skin problems, hormonal imbalances, or chronic inflammation. Yet research published in Nature Reviews Gastroenterology and Hepatology has demonstrated that gut health may be a root cause factor in many of these conditions.

This is why “Test, Don’t Guess” often includes gut health assessment. Understanding what is happening in the digestive system may reveal root causes that would otherwise go unaddressed.

Supporting Your Digestive Health

The NIDDK recommends several foundational strategies: eating a balanced diet rich in fiber, staying hydrated, managing stress (which directly affects gut function), and working with healthcare providers to address persistent digestive concerns.

At Nepute Wellness, we build on these foundations with targeted approaches including microbiome testing, food sensitivity assessment, and personalized nutritional counseling.

Dr Nepute’s vitamins particularly the D3 and Zinc, have been life changing for me! My blood tests showed a D3 number of a #4…That’s unheard-of low. I took vitamins from Walmart and they did nothing. I took Dr.. Nepute’s vitamins for 2 years, and now my D3 number is a whopping #81. I feel so much better with so much more energy. Thanks Dr. Nepute!

Dr. Nepute Wellness Center is designed to be a diagnosis Center for the body. What I found to be especially unique is dr. Nepute is willing to cooperate and work with other doctors. In my son’s case, he is already working with a chiropractic specialists but does it have the other diagnostic tools. Dr. Nepute was able to get to the bottom of my son’s condition rather quickly and he prescribed a natural product that should start helping to solve the problem in my son’s body. Talk to the pool table leaves my son is suffering from leaky gut that has gone what is handed for many years. The products are moderately pricey but if these price will truly help my son get better than it’s worth it. I’ve spent about the same amount are viruses the past. But at least this time he’s only taking three products not 40 different vitamins. Some happy that it will be less of a burden on my son. I truly believe that if you have any kind of illness or if you have something that’s been playing you for a very long time you should go and see dr. Nepute and have him take a look. There initial patient see diagnostic check is relatively inexpensive. Go in have him check you out I’m sure you will be very happy to get started on a health and Wellness recovery.
