Mitochondria’s Impact on Adrenal Gland Diseases – Part 1
The mitochondria in all our cells are the energy power plants or the engine block for our bodies. They produce a chemical called ATP, which is the body?s currency for energy. Mitochondria provide over 90 percent of the body?s energy. When someone is diagnosed with mitochondrial disease, it means that they are not functioning properly in the area of energy production. The resulting symptoms are varied and often mimic those suffering from adrenal gland diseases, making it difficult for many doctors to be able to distinguish between the two in order to make a proper diagnosis.
Medically, mitochondrial disease is a category of different diseases grouped together. These different diseases present in different forms and vary widely with no two patients presenting with the same symptoms.
The symptoms appear similar to quite a few diseases, including Alzheimer?s disease, autism, chronic fatigue, Lou Gehrig?s disease, muscular dystrophy, and Parkinson?s disease. Mitochondrial weakness at the sub-clinical state also mimics conditions such as liver sluggishness, extracellular matrix congestion, as well as the previously mentioned adrenal gland diseases like Adrenal Fatigue Syndrome (AFS).
When the mitochondrial system is malfunctioning then it can be fatal, such as Leigh?s disease. This affects one in 25,000. Most mitochondrial dysfunction are not fatal, but living a normal and vibrant lifestyle can be severely compromised. One in 2,500-3,000 people are affected in some way by mitochondrial disease.
Symptoms of Mitochondrial Disease
Each mitochondrion is an energy factory within the cell. Sugars and fats are imported, broken down, converted and exported as ATP. This highly complex process requires various special protein complexes at different stages for fruition. Mitochondrial diseases are caused by genetic mutations, resulting in deficiencies in one or more of the protein complexes required to make ATP. When a cell is filled with defective mitochondria, not only does it become deprived of ATP, but it can also accumulate a backlog of unused fuel molecules and oxygen. Potentially harmful byproducts such as lactic acid can accumulate. A state of lactic acidosis can result and symptoms can be mild to severe. They include muscle fatigue, aches, and cramps. Meanwhile, unused oxygen in the cells can be converted into highly destructive compounds called reactive oxygen species, including free radicals that cause oxidative stress.
ATP made from mitochondria provides the predominant source of power for muscle cells to contract and supports proper nerve cell firing. The combination of reduced energy availability with mitochondrial diseases and resulting free radical accumulation in these cells can also give rise to subtle signs and symptoms such as brain fog, joint pain of unknown origin, psoriasis, and fatigue.
When the mitochondrion fails, energy production slows down inside the cell, which is harmful and can even cause the cell to die off. Symptoms all depend on which cells in the body have the malfunctioning mitochondria. Diseases of the mitochondria appear to cause the most damage to cells of the brain, heart, liver, skeletal muscles, kidney and the endocrine and respiratory systems.
- Low energy state and fatigue, with low exercise tolerance level and fatigue on exertion.
- Low cardiac output, leading to congestive heart failure.
- Developmental delays below the normal growth curve
- Gastrointestinal disorders, such as leaky gut, irritable bowl, and constipation
- Lactic acidosis, with symptoms such as muscle soreness, pain and cramps.
- Liver disease and congestion, with symptoms such as brain fog, and an inability to tolerate medications or supplements
- Loss of motor control, coordination
- Neurological problems
- Susceptibility to infection
- Swallowing difficulties
- Poor thyroid function
Mitochondrial disease or adrenal gland diseases can make their appearance at any age. In many people, these diseases are not even diagnosed, as there is a lack of awareness in the medical community and in the public at large.
Mitochondria: Much More Than Energy Factories
There are as many as 3,000 genes that make up one single mitochondrion. In addition to energy production, mitochondria are what contain the rate-controlling enzymes for the biosynthesis of pyrimidine (dihydroorotate dehydrogenase) and the synthesis of heme (D-aminolevulinic acid synthase). In the liver, mitochondria work in a specialized manner to detoxify ammonia, which forms in the urea cycle. Mitochondria are also needed to metabolize cholesterol, for the synthesis of testosterone and estrogen, to metabolize neurotransmitters and for the production and detoxification of free radicals. They perform all of these functions as well as metabolizing or oxidizing the fat, carbohydrates and protein we consume.
Genocopies and Phenocopies
Since mitochondria are responsible for performing so many varied and different functions in all the different bodily tissues, there are hundreds of different kinds of mitochondrial diseases and disorders. Every single one has its own spectrum of abnormalities. This is very confusing to patients and physicians alike, especially when trying to diagnose the problem.
Because of the complexity of the interactions between the hundreds of cells and genes that all must work together to keep our metabolic systems running well, it is a feature of mitochondrial disease that the identical mtDNA mutations may not necessarily result in the same diseases. Genocopies are diseases caused by the identical mutation, but may not look identical clinically.
The opposite is also true: different DNA mutations can progress to the exact same diseases. These diseases are known in genetics as phenocopies. A solid example of this phenomenon is Leigh syndrome, a fatal disease that can actually be caused by perhaps a dozen very different genes.
Identifying Adrenal Gland Diseases and Mitochondrial Disease?
When considering a diagnosis of mitochondrial disease, patients must be evaluated very carefully for other diseases as well. Anytime anyone presents with fatigue and low energy state, a complete cardiac, hormonal, hematological, oncological and metabolic workup is needed. When the result is normal and out of the box a different diagnosis needs to be considered. They include adrenal gland diseases, like Adrenal Fatigue Syndrome, and mitochondrial disease.
Unfortunately, there isn?t a single test developed yet to diagnose mitochondrial disease in the majority of patients. In today?s medical environment oxidative phosphorylation (OXPHOS) enzymology alone is not sufficient for an accurate diagnosis.
Mitochondrial disease is diagnosed by using an integrated approach with multiple means and a detailed history, which would include:
- Brain imaging
- Clinical observations
- Evaluating laboratory results
- Muscle biopsies
An alert physician with experience in orthomolecular medicine is usually required for a proper diagnosis as it is rare that genetic testing would be adequate for an accurate diagnosis of the disease.
Tests Used for Diagnostic Purposes
There are three different categories of diagnostic criteria:
- Genetic testing of mitochondrial DNA (mtDNA) and nuclear DNA
- Metabolic markers of blood, urine and cerebral spinal fluid
- Muscle testing assessing liver respirometry, CoQ levels, and muscle pathology
Diagnosis is considered positive if two or more tests from two categories show abnormal results.
Defective mitochondria produce large quantities of oxygen free radicals. Comparing patients who have a mitochondrial disorder with healthy people, researchers have found that their blood glutathione level was significantly reduced in white blood cells from mitochondrial diseased patients. This indicates a low level of antioxidant defenses. Measuring blood glutathione levels can be used as a biomarker to monitor the mitochondrial disorders or adrenal gland diseases.

Dr. Lam’s Key Questions
How does having candida affect my adrenals?
When your body is stressed, the microbiome balance can become disturbed, and as a result, Candida may flair up.
