What Causes the Inability to Absorb Digested Nutrients?

Nutrient malabsorption is a critical yet often overlooked health issue that can seriously impact one’s overall well-being. When your body is unable to absorb digested nutrients effectively, it can lead to a cascade of health problems, ranging from fatigue and weight loss to more severe conditions such as anemia and osteoporosis. 

You can take all of the supplements, but they will simply pass through your body if the gut isn’t functioning properly.

At InSpero Medical, we use the latest functional medicine techniques to repair your gut and promote proper digestion. As you learn more about nutrient absorption, it’s important to understand the underlying causes and recognize a few of the most common symptoms. We hope that this blog article is informative in your journey to address your inability to absorb digested nutrients.

What Happens When You’re Unable to Absorb Digested Nutrients?

Nutrient malabsorption is a complex condition where the intestines demonstrate an inability to absorb essential nutrients from the food consumed. This can be caused by many factors, including intestinal damage, enzymatic deficiencies, or disorders affecting the gut’s microbiome. 

The immediate effects on the body are often noticeable and uncomfortable. Common symptoms include bloating, often a result of gas and fluid retention; diarrhea, which can occur when unabsorbed digested nutrients draw excess water into the intestines; fatigue, due to the lack of vital nutrients needed for energy production; and inexplicable weight changes, either gain or loss, depending on the body’s response to nutrient and calorie deficiency.

If these signs are overlooked and nutrient malabsorption persists, the long-term consequences can be severe. The body may begin to show deficiencies in specific vitamins and minerals, leading to more pronounced and diverse symptoms. Skin rashes or dry skin might appear as a result of vitamin deficiencies, such as those in vitamin A, B vitamins, and essential fatty acids. 

Weakening of the bones is another serious risk, typically resulting from insufficient calcium, vitamin D, and phosphate absorption, predisposing individuals to fractures and conditions such as osteoporosis. Moreover, a prolonged lack of adequate nutrient absorption can affect mental health, contributing to symptoms such as depression and anxiety, which may stem from inadequate levels of neurotransmitter precursors and other nutrient-based imbalances in the brain.

Addressing these issues early on can prevent the progression of symptoms and help maintain overall health and well-being.

Key Factors Contributing to Nutrient Malabsorption

We can see that many symptoms of nutrient malabsorption can be classified as “chronic.” Many people suffer for years without relief because conventional care isn’t able to pinpoint the root of the problem. However, as functional medicine doctors, we at InSpero Medical have noticed that patient symptoms are often due to the following causes:

  1. Leaky Gut

Also known as increased intestinal permeability, leaky gut occurs when the lining of the small intestine becomes damaged, allowing toxins, microbes, and undigested food particles to “leak” through into the bloodstream. This condition is closely linked to various autoimmune diseases and chronic gastrointestinal disorders, which can significantly hinder the body’s ability to absorb digested nutrients.

  1. Toxicity

High levels of toxins in the body from environmental sources, lifestyle choices, or poor water and air quality can impair organ function. The liver and kidneys, crucial for detoxifying the body, when overloaded, can impact digestion and, subsequently, nutrient absorption.

  1. Poor Diet

Consuming a diet low in vitamins, minerals, and other essential nutrients, or high in processed foods, can naturally lead to malabsorption. The gut needs a balance of nutrients to function optimally; a poor diet disrupts this balance, exacerbating absorption issues.

  1. Poor Mitochondrial Function

Mitochondria are the energy powerhouses of the cells. When they function poorly, often due to genetic factors, aging, or environmental stressors, they can affect how cells are able to absorb and use digested nutrients, leading to systemic health issues.

How Functional Medicine Can Help

Functional medicine offers a comprehensive approach to treating nutrient malabsorption by addressing its root causes rather than just alleviating symptoms. Here are some strategies to try when you find you have an inability to absorb digested nutrients:

  • Supplementation: Customized vitamin and mineral supplements can help rectify deficiencies and support overall gut health. Note that these supplements are meant to primarily restore gut function. While supplements can help in getting the body the nutrients it needs, we shouldn’t use them as Band-aids over the deeper problem of nutrient absorption.
  • Gut Restoration: Probiotics, prebiotics, and dietary changes can restore gut flora balance, enhancing the gut’s lining and improving nutrient uptake.
  • IV Therapy: Direct delivery of nutrients into the bloodstream via IV therapy ensures that nutrients bypass the digestive system completely, providing immediate benefits to those severely deficient.

These approaches, combined with lifestyle modifications, can dramatically improve nutrient absorption and enhance overall health.

I’m deeply grateful for the care and support I received from the incredible team at Inspero Medical. From the very beginning, I felt truly seen, heard, and cared for. While I’ve chosen to continue my wellness journey with a cardiologist to explore some more specific needs, that decision is not a reflection of any dissatisfaction—in fact, it’s quite the opposite. The Inspero team has played a meaningful and foundational role in helping me reach this next step, and I’ll always appreciate the heart, expertise, and encouragement they brought to every interaction. A special thank you to Dr. Tereza, Kirsten, Erin, and Heidi—each of you brought such compassion, insight, and genuine care to my experience. You’ve been an important part of my path, and I’m sincerely thankful. I wouldn’t be surprised—and would absolutely welcome it—if my journey brings me back to Inspero down the road.

Grateful for Inspero, Dr. Tereza, Kirsten, and the entire staff. All have hearts full of love, compassion and care. It shows in every detail. When I showed up for my initial appointment I was both physically and mentally broken. Conventional treatment was getting me nowhere. I saw many doctors and specialists. All unable to provide the help I desperately needed. With the help of Inspero, we were able to finally identify what ultimately contributed to the major decline in my health for the past 8 years. The knowledge, experience and the testing they provide finally got to the root cause of why my chronic condition was worsening year after year. Dr. Tereza helped me address, learn and heal the root causes of my illness through a variety of holistic modalities Inspero provides. You feel loved, cared for, peaceful and blessed. And best of all….I got my life back! Inspero will always be my home for wellness.

2024 I first reached out to Inspero Medical in Edwards, CO in the fall of 2020. I had seen 50 doctors over a 10-year period of time – including UCHealth in Denver and the Mayo Clinic in Minnesota – and no one could figure why I did not feel well. We did a Viral Load Blood Test at Inspero Medical, and there it was – I had been carrying Lyme Disease for a solid decade. Lyme is a simple problem of a blood infection from a bug bite, and it is in every state now – Lyme Testing should be a STANDARD TEST done once a year in any medical practice – and it will be a standard, routine test in the future. Inspero Medical is two brilliant Internal Medicine Traditional Medicine Doctors that are also Certified in Functional Medicine – so you get the benefits of both disciplines at Inspero Medical. In the three years that I have worked with them, they I have cleared up SO MANY health problems for me. The Testing in Functional Medicine is far advanced from everyday traditional Doctors in Standard Medicine, and that is a big part of diagnosing any condition. After clearing up one thing after another I can honestly say I am a new person. If you are looking for a Medical Practioners, that go far beyond the average Medical Experience of Standard Medicine – then Inspero Medical is for you. I even had my husband and our grown-up son work with them and they had the same, experience of in-depth testing and significant health improvement. Inspero Medical is truly the future of Medicine. I am forever Grateful to Inspero Medical for saving my life! Thank you with all my Heart!

Everyone at InSpero is exceptional — they are incredibly caring, organized, and knowledgeable. Before finding InSpero, I was jumping from doctor to doctor, unable to get clear answers or help for my many symptoms. When I became a patient at InSpero, they were finally able to pinpoint the root causes of my gastrointestinal, hormonal, and autoimmune issues. The doctors answer all of my questions during appointments, so I clearly understand what’s going on and the reason for the treatment plan, and they are very good at responding to messages through the patient portal. You can tell how much they care. It’s so rare to find such skilled and compassionate physicians. I am beyond grateful for everything they have done for me!

The team at Inspero has given me the highest quality healthcare experience I have ever experienced. Not only are the doctors incredibly knowledgeable on a comprehensive set of topics, but they understand how the body works together as one organism. They know medicine but also are curious, inquisitive and caring enough to not just prescribe a pill to mask symptoms, but to find and treat the root cause. Moreover, they are incredibly organized and even follow up with me to take care of maintenance to my health care! They care about their patients and actually want to help us, and they are great at explaining an issue to me when I have questions. I am so incredibly grateful to have found Inspero and know you will be, too, if you are ready to live your best and healthiest life while having it be an actually positive experience!

I’ve been working with the Doctors and staff at Inspero for five years on many different issues that my conventional Doctors did not have the capacity to address. The Doctors and staff are compassionate and supportive. The care and expertise which is cutting edge medicine, technology and education is beyond any other health care I’ve received related to my concerns. It’s empowering to be a participant with them in my health and I’ve not only had success in my treatments but have have learned so much from all of them. I look forward to my appts and being greeted by everyone with a smile and genuine concern and compassion. I highly recommend to anyone and especially those who feel they don’t know what to do next.
