Chris Kresser har lagt upp en ny artikel om 5 orsaker till utmattning.
#1: Chronic infectionsSeveral studies have found that patients complaining of chronic fatigue have lab markers consistent with active pathogen activity and infection. (3) These include stimulation of lymphocytes (a type of white blood cell involved in fighting infections), abnormal patterns of CD4+ and CD8+ T cells (which are also involved in fighting infections), and lymphadenopathy (an enlargement of the lymph glands consistent with infection).
#2: Biotoxin illness (and Chronic Inflammatory Response Syndrome)A biotoxin is a poisonous substance produced by living organisms. They can be further classified into fungal biotoxins (e.g. mycotoxins), microbial biotoxins, plant biotoxins, short phytotoxins and animal biotoxins. These biotoxins are found in water-damaged buildings, marine or freshwater environments, and in microorganisms that infect humans.
Biotoxins are not a problem for most people. When we are exposed, the toxin is “tagged” and identified by the immune system and broken down and removed from the body by the liver.
#3: Impaired methylationIf you’ve been following my work for the past couple of years, you’re already familiar with methylation and its role in human health and disease. I’ve dedicated two podcast episodes to it thus far, and I’ll be writing and speaking about it more in the future.
Methylation is a complex biochemical process. Rather than dive deeply into how it works, I’m going to focus here on its role in chronic fatigue. If you’re new to methylation, listen to my Methylation 101 podcast (or read the transcript) to get some important background.
Defects in the methylation cycle can lead to both low levels of the active forms of folate and B12, and changes in folate and B12 metabolism. B12 and folate deficiency cause fatigue, and supplementation with B12 has been shown to have a positive effect in patients with fatigue. (11)
#4: Mitochondrial dysfunctionMitochondria are known as the “battery” or energy powerhouse of the cell. They are organelles inside of cells that take in nutrients, break them down, and create ATP (adenosine triphosphate), which is the fundamental energy unit of the cell.
In addition to their role in energy production, mitochondria are also involved in the production of reactive oxygen species (ROS), regulation of amino acids, metabolites, and enzyme co-factors, neurotransmitter synthesis, insulin secretion, and pyrimidine and lipid production.
Because of these numerous and important roles, any defect in the function of the mitochondria will have widespread consequences. Mitochondrial dysfunction has been linked not only to fatigue, but to a wide range of health conditions like cancer, diabetes, fibromyalgia, and serious mental disorders like schizophrenia and bipolar disease.
#5: Gut dysfunctionThere are numerous pathologies related to gut health that are associated with fatigue, including small intestinal bacterial overgrowth (SIBO), chronic infections (bacterial, viral, parasitic), dysbiosis and fungal overgrowth, intestinal permeability, and food intolerances—to name a few.
For example, one study showed that infection with a parasite called Giardia lamblia is associated with an increased risk of chronic fatigue that persists for at least 53 years after the infection has been treated. (17) Another study found that patients with chronic fatigue had abnormally elevated levels of a yeast called Candida albicans in their stool. (18) Finally, intolerance of gluten and other food antigens is associated with fatigue. (19)
