Intestinal dysbiosis refers to a significant change in the ratio of normal intestinal bacteria and causes certain clinical symptoms. Under normal conditions, there is a relatively fixed ratio between various non-pathogenic bacteria in the intestinal tract, and they can decompose certain substances, produce certain vitamins needed by the body, and inhibit the reproduction of certain pathogenic bacteria, which are beneficial to maintain the normal physiological functions of the human digestive tract. However, if the body resistance is low, or due to chronic intestinal diseases, long-term application of a large number of antibiotics, can be a large number of kill or inhibit the normal flora and occur dysbiosis, can cause fungal or staphylococcal enteritis. Patients may have symptoms such as diarrhea, abdominal distension, and digestive tract dysfunction.
Early diagnosis of dysbiosis is a prerequisite for proper and effective treatment.
The diagnosis of dysbiosis consists of three parts: 1, the presence of dysbiosis.
2, the degree of dysbiosis.
3, the cause of dysbiosis.
Patients with dysbiosis often show severe diarrhea or chronic diarrhea, in the application of antibiotics, such as the sudden occurrence of diarrhea, or aggravation of the existing diarrhea, that may have occurred dysbiosis.
The degree of dysbiosis can be divided into three degrees: Ⅰ degree (mild) is reversible mild dysbiosis, can recover after removing the causative factors, the symptoms disappear, clinically seen in acute disease caused by intestinal dysfunction; Ⅱ degree (moderate) dysbiosis more serious, remove the cause often can not recover, more chronic intestinal symptoms; Ⅲ degree (severe) dysbiosis, manifested as alternating flora or dual infection.
Detailed knowledge of stool characteristics and laboratory tests can identify some specific causative flora disorders, such as Shigella, Salmonella, Campylobacter, Clostridium difficile and rotavirus infections.
