We have all experienced depression at some point in our lives. Depression is a disorder that affects more and more people. It affects emotions and assessment skills and compromises quality of life. Generally, depressed people may not always be able to concentrate. As a result, their performance in various fields, such as academic or professional, declines, leading to additional stress. In extreme cases, it can lead to severe depression and self-harm with thoughts of self-destruction and death.
Depression, stress and anxiety are interrelated, leading to changes in eating habits and sleep patterns. Stress and depression affect the release of cortisol (a stress hormone). Cortisol modifies the intestinal immune system, eventually altering the number of microorganisms in the gut. Causes significant changes in the intestinal microbiota based on the severity or decay of individual species. However, no introduction of different species or complete elimination of specific bacterial species has been observed.
Gut Bacteria And Depression
. In addition, depressed individuals experience a reduction in carbohydrate-metabolizing bacteria compared to healthy individuals. These include bifidobacteria, phobobacteria,

And Ruminococcus. Many other bacterial species, which play a key role in the metabolism of proteins and amino acids, continue to be overpopulated in depression. Such bacteria are Clostridium, Klebsiella, parabacteroids, and Streptococcus
Depression and intestinal dysbiosis are deeply related because the intestines and the brain share two-way communication. The reduced abundance and accumulation of microorganisms in our gastrointestinal tract affects our mood and mood. Small studies that have found a link between dysbiosis and behavioral abnormalities in neurodevelopmental disorders have shown such correlations.
In addition to digestion, fermentation and production of vitamins, the intestinal flora also serves as a source of neurotransmitters such as serotonin, gamma-aminobutyric acid (GABA), glutamate, dopamine and noradrenaline. These metabolites play an important role in maintaining intestinal immunity and preventing intestinal colonization by pathogens. Decreased levels of serotonin, noradrenaline, dopamine, and disorders of the glutamate-GABA system are closely related to depression and alter intestinal biology. In addition, GABA produces,
On the other hand, environmental factors, intestinal well-being, and the relative diversity of intestinal microorganisms actively modify the microorganisms that control the size of the neurotransmitter. If no other neurotransmitter metabolites of serotonin and tryptophan are used, allow blood to circulate.
New Evidence Links Specific Gut Bacteria To Depression
And it affects behavioral reactions. The intestinal microbiota indirectly modulates brain function through changes in inflammatory conditions and the immune status of the intestine.
Dietary fiber found in whole grains, fruits, vegetables, nuts, legumes and whole grains is indigestible. Our gut bacteria convert long edible fibers into short-chain fatty acids (SCFAs). These SCFAs play an important role in intestinal biology, acting as an energy source for intestinal cells and the intestinal microbiota. Interestingly, SCFA blocks enzymes that act as immunosuppressants and anti-inflammatory drugs.
Antidepressant agents. As a result, low SCFA levels contribute to impaired output energy and altered neurotransmission, leading to depression. SCFAs, which are produced by bacteria that are suitable for the gut, often pass through the systemic circulation and enter the brain through the blood-brain barrier via specialized transport. These SCFAs produce neurotransmitters, offer neuroprotection, and act as natural antidepressants.
In addition to carbohydrate metabolism, the intestinal flora participates in the metabolism of proteins and amino acids through fermentation or fermentation. However, excessive consumption of protein can lead to overproduction of toxic products such as ammonia, putresine and phenol, which can lead to stress and depression. In addition, dysbiosis, which causes low carbohydrate metabolism and high protein metabolism, is associated with intestinal inflammation leading to anxiety and depression.
Scientists Find A Possible Link Between Gut Bacteria And Depression
Intestinal bacteria, such as Bifidobacterium, which synthesize vitamins such as riboflavin, niacin, and folate, are less common in depressed people. Low levels of folate and thiamine have been found to be strongly associated with depression and inversely related to the severity of symptoms.
On the other hand, it is reasonable to believe that depression due to unhealthy eating or sleeping habits can lead to digestive problems and dysbiosis. Decreased ability to digest protein leads to the accumulation of residual protein in the colon, which stimulates the growth of the microorganisms that eat them. This eventually leads to high fermentation and inflammation of the intestines.
Many disorders associated with dysbiosis, irritable bowel syndrome (IBS), and inflammatory bowel disease (IBD) are also associated with depression. An overpopulation of pathogenic bacteria causes inflammation of the intestines, damaging the intestinal epithelium and endangering the permeability of the intestinal wall. In severe cases, bacterial or intestinal epithelial cells cross the blood-brain barrier, eventually leading to anxiety, depression, and related disorders.
Often, the activation of the vagus nerve, which regulates digestion, is responsible for controlling dysbiosis and our mental health. Pathogens in the intestinal flora affect the vascular nerve endings located in the intestine, causing subsequent pathological changes in the central nervous system and transmitting symptoms such as depression. In addition, serotonin activates the vagus nerve and bowel movements.
Gut Microbiome & Depression Pathophysiology|role Of Pre And Probiotics
Because the gut affects the mind, it makes sense to emphasize the role of food in managing depression. One way to maintain the integrity of the intestinal environment involves the intelligent consumption of polyunsaturated fatty acids (PUFAs). PUFA shares a link between the gut microbiome and our mood. Interestingly, the balance of PUFA plays an important role in the adhesion of bacteria to the intestinal mucosa. Omega-6 PUFA produces molecules that maintain the permeability of the intestinal mucosa and protect against inflammatory damage.
Probiotics help to improve the diversity of the gut microbiota and promote behaviors such as anxiety and depression. Fecal microbiota transplantation is another promise for treating depression.
Depression and intestinal flora are intertwined. Therefore, to get an idea of the true condition of your gut, it is crucial to do a “gut microbiome test”. The latest “DNA sequencing technology” and algorithm-based data retrieval can help identify individual microbiome signatures in fecal samples. Based on the results, a treatment plan has been developed that includes a combination of diet, lifestyle and probiotics. The resulting lifestyle will help you lead a depressed life.

Depression is one of the leading causes of disability, morbidity and mortality in the world. The functions of the brain-intestinal axis are impaired due to inadequacy of the brain, immune system, endocrine system and intestines. All traditional treatments for depression target the brain with various medications and / or psychotherapy. Unfortunately, most patients do not receive any treatment. Studies have shown that the gut microbiota can be a direct cause of this damage. Abnormal microbiota and disorders of microbial-intestinal-brain function can lead to mental disorders, while resolving these disorders can alleviate depression. Nowadays, the modulation of the intestinal microbiota has become a hot topic in the therapeutic research of mental disorders. Depression is closely related to the health of the brain-intestinal axis and maintains / restores the normal state of the intestinal microbiota to help prevent / treat mental disorders.
