Ongoing fatigue and low energy are frustrating symptoms that can originate from many complex underlying physiological issues. In this article, we will explore how specialized functional medicine testing provides a comprehensive analysis of potential factors contributing to the depletion of your energy reserves. By going far beyond standard lab screens, advanced functional blood panels allow our practitioners to uncover the root causes unique to your case so that individualized, precision treatment protocols can be developed based on your results.
Targeted treatments based on your results may include nutrient therapies, dietary changes, correcting deficiencies, hormone balancing, reducing inflammation and oxidative stress, improving sleep quality, healing the gut, and repairing metabolic function. The key is using advanced functional labs to pinpoint the root causes of what is draining your energy reserves so it can be effectively treated, and your natural vitality restored.
Symptoms and Health Impacts of Fatigue
Fatigue refers to an ongoing sense of tiredness, lack of energy, and feelings of exhaustion that persist despite adequate rest, with chronic fatigue being defined as fatigue lasting for over 6 months. The main symptom is severe exhaustion with physical or mental activity, but other symptoms may include widespread muscle and joint pain, headaches, poor sleep quality, difficulty concentrating, mood changes, dizziness, and frequent illnesses or infections.
Chronic fatigue can stem from a variety of underlying issues such as anemia, thyroid disorders, adrenal imbalance, chronic infections, autoimmunity, sleep apnea, and more. When the cause is unknown, it is termed chronic fatigue syndrome (CFS), which is a condition that is estimated to affect up to 2.5 million Americans. Ongoing fatigue can greatly reduce one's quality of life by making it challenging to get through daily activities, work productively, exercise, and fully participate in life. Severe fatigue has been associated with high rates of absenteeism and unemployment, and it can strain relationships, lead to social isolation, and negatively impact emotional health. Treating the root causes of fatigue through functional medicine testing and personalized care plans can help restore energy, improve daily function, and enhance overall well-being.
Potential Causes of Fatigue and Low Energy
Fatigue and low energy are unfortunately very common in today's fast-paced world. While fatigue may seem like a simple issue, there are often complex root causes behind it that require proper medical investigation. The good news is that with the right functional medicine testing, the factors draining your energy can be identified and corrected. Here are the common causes:
- Anemia - Low red blood cell count, often from iron or vitamin B12 deficiency, results in inadequate oxygen delivery to tissues.
- Hormonal Imbalances - Low thyroid, adrenal fatigue, or sex hormone dysregulation can disrupt metabolic processes.
- Nutritional Deficiencies - Lack of iron, vitamin D, B vitamins, magnesium, and amino acids are needed for energy production.
- Chronic Conditions - Diabetes, obesity, inflammation, and infections deplete energy reserves.
- Sleep Disorders - Insomnia, sleep apnea, and restless leg syndrome lead to non-restorative sleep.
- Medications - Certain prescription drugs can cause fatigue as a side effect.
- Stress - Chronic activation of stress response diverts energy from normal body processes.
If you are struggling with any of these symptoms, lab tests are designed to uncover the root cause of the issue to target it with personalized care. With comprehensive functional lab testing, our practitioners can get to the bottom of what is causing your ongoing fatigue.
Lab Tests to Identify Root Causes
Since fatigue has many potential causes, functional medicine practitioners use lab panels to pinpoint imbalances specific to each patient. Common lab tests include:
Complete Blood Count (CBC): The Complete Blood Count assesses anemia, blood cell abnormalities, and infections. It checks levels of hemoglobin, hematocrit, and red blood cell size and number. Low hemoglobin indicates anemia which reduces oxygen transport.
Iron Studies: Iron studies measure serum iron and ferritin (the storage form of iron). Low levels identify iron deficiency anemia, which is a major cause of fatigue. High ferritin may signal inflammation.
Thyroid Panel: The thyroid panel evaluates TSH, T4, and T3 hormones. Hypothyroidism is linked to fatigue, weight gain, hair loss, and irritability.
Adrenal Function: Cortisol and DHEA hormones reflect adrenal gland activity. Low cortisol indicates adrenal insufficiency while high cortisol is seen in chronic stress. Low DHEA is also associated with fatigue.
Comprehensive Metabolic Panel: The comprehensive metabolic panel assesses blood glucose, electrolytes, liver function, and kidney function. Diabetes and electrolyte/fluid imbalances can substantially lower energy levels. Kidney and liver disease are also fatiguing conditions.
Vitamin D: Vitamin D is critical for musculoskeletal health and regulating immune function. Deficiency is associated with fatigue, muscle pain, and risk of many diseases.
Vitamin B: B12 and folate are required for red blood cell formation and energy metabolism. Deficiencies in these vitamins cause fatigue and neurological symptoms.
Celiac Screen: The celiac screen measures TTG IgA, total IgA, and DGP IgA antibodies. Those with celiac disease often feel fatigued until gluten is eliminated from the diet.
Food Sensitivity Testing: Food sensitivity testing identifies immunoglobulin G (IgG) antibodies to different foods. Removing reactive foods reduces inflammation and gut problems contributing to fatigue.
While the lab tests mentioned provide critical information, functional medicine practitioners often run additional specialized tests based on symptoms and case history. For example, comprehensive hormone panels help identify hormonal imbalances related to the thyroid, adrenals, reproductive system, and growth hormone that can provoke fatigue. Testing cortisol, DHEA, testosterone, estrogen, and progesterone levels provide key insights.
Functional immunology and allergy testing, including a Celiac panel, food sensitivity testing, organic acid testing, and inflammatory marker assessment, can detect gluten reactions, issues with microbial balance, and hidden infections along with body-wide inflammation that exhausts the immune system. Evaluating the complete picture allows our practitioners to get to the root of your fatigue and address it effectively.
Interpreting Results and Developing a Treatment Plan
In summary, fatigue and low energy often result from complex underlying imbalances or deficiencies that require a functional medicine approach to properly identify and treat. Through comprehensive lab testing that goes beyond standard screens, we can gain insight into factors that may be draining your energy reserves, such as anemia, hormonal dysfunction, chronic inflammation, infections, micronutrient status, and food intolerances. Based on your unique test results, our practitioners at Internal Healing & Wellness MD develop a personalized protocol using diet changes, targeted nutritional support, herbal therapies, bioidentical hormones, lifestyle modifications, and other interventions to specifically correct the imbalances contributing to your fatigue.
The goal of functional medicine is to address the root causes of health issues in order to restore well-being long-term. If you are struggling with ongoing exhaustion, we can help uncover why through advanced testing and provide an individualized treatment plan to help resolve fatigue holistically.
