- Large motor delays
- Failure to thrive, growth delays
- Low muscle tone
- Extreme fatigue
- Inability to regulate temperature
- Autistic symptoms
- Global muscle weakness
- Difficulty waking
Even if your child does not display any of the “classic” symptoms of mitochondrial dysfunction (listed above), your child may still be affected.
It is now believed by many research scientists and an increasing number of physicians that mitochondrial dysfunction may be a critical part of the underlying pathophysiology in the following health conditions:
- Bipolar disorder
- Parkinson’s disease
- Chronic fatigue syndrome
- Alzheimer’s disease
- Some gastronintestinal disorders, among others

What is mitochondrial dysfunction?
Mitochondria are the “power plants” of the body. They make the energy to power cells in every part of the body, including the major organs requiring significant amounts of energy to function properly.
The organs in the body that require the most energy are the brain, muscles, liver, kidneys, gastrointestinal tract, heart and lungs. Mitochondrial disease or mitochondrial dysfunction is what occurs when the mitochondria are not able to do their job due to genetic or environmental factors.
When the mitochondria are not working properly, a whole host of symptoms may appear. According to the UMDF (United Mitochondrial Disease Foundation), an affected individual may have:
- Gastrointestinal problems (reflux, vomiting, constipation, diarrhea)
- Swallowing difficulties
- Failure to thrive
- Heart and kidney problems
- Muscle failure
- Heat/cold intolerance
- Lactic acidosis
- Immune system problems
- Liver disease
An undiagnosed child may exhibit feeding problems, be unable to fight typical childhood infections or have repeated infections and fevers without a known origin. A “red flag” for mitochondrial disease is when a child has more than 3 organ systems with problems or when a “typical” disease exhibits atypical qualities.
How do I know if my child has mitochondrial dysfunction?
There are certain blood tests that may indicate that a child has mitochondrial dysfunction. Ask an integrative or holistic physician or practitioner to look for the following “red flags” in laboratory blood work:
- Elevated ammonia, alanine, alanine/lysine ration 3, glysine, proline, tyrosine, sarcosine, lactate/pyruvate ratio, acyl:free carnitine ratio, elevations suggesting disruptions in fatty acid oxidation
- Reduced free and total carnitine
- Irregular urine organic acid screening-TCA intermediates, ethylmalonate, 3-methylglutaconate, dicarboxylic acids, methylmalonic acid
OR consider seeing a geneticist who specializes in mitochondrial disease.
