The outbreak of intestinal bacteria will not only cause indigestion, but may also cause 5 kinds of nervous system diseases! The microorganisms in the gut can maintain the normal physiological functions of the human body. They are known as the 2nd brain of human beings. The imbalance of microorganisms in the gut not only cause intestinal diseases, but also affect the brain function through immune inflammation, neuroendocrine and nerve signal transmission, and even cause degenerative diseases of the central nervous system.

1.Parkinson’s disease: Patients may experience non-motor symptoms, such as slow gastrointestinal function, constipation and others. These are the precursor symptoms of Parkinson’s disease. This is because the anti-inflammatory beneficial bacteria in
the stool and intestinal mucosa are significantly reduced, whereas the related bacteria that stimulated the inflammation are significantly increased.

2.Alzheimer’s disease: In 2017, the Taiwan National Institutes of Health had found in the animal experiments that the imbalance of microorganisms in the gut can cause brain nerve degradation and induce Alzheimer’s disease. The research team of Harvard University also published in scientific journal “Nature” in 2018 that the intestinal bacteria by-product can prevent cerebral neuropathy, which may help
Alzheimer’s disease.

3.Multiple sclerosis: It is an autoimmune disease. Dr. Gurumoorthy Krishnamoorthy of Max Planck Neurobiology said that the bacteria that cause multiple sclerosis are not pathogenic bacteria, but bacteria that are useful for digestion.

4.Depression: The research team of the Rega Medical Research Institute in Belgium ound that depression has a subtle relationship with the human intestinal flora. The intestinal flora can produce many substances that affect neuropsychological activities including emotions.

5.Autism: According to the US Department of Disease Control, long-term diarrhea or constipation in children with autism is 3.5 times that of normal children because of the abnormal imbalance of intestinal flora.
