It may be a gastrointestinal problem. There are 400 kinds of bacteria in the stomach of healthy people, and the beneficial bacteria are absolutely dominant. Once the harmful bacteria occupy the absolute advantage, the gastrointestinal flora will be seriously unbalanced, and harmful bacteria and their toxins will erode the gastrointestinal mucosa, leading to gastrointestinal diseases such as gastritis, peptic ulcer and colitis. \ x0d \ x0d \ Since gastrointestinal diseases are caused by harmful bacteria, it is reasonable to say that as long as harmful bacteria are eliminated, gastrointestinal diseases will be contained. As a result, antibiotic drugs came into being. However, antibiotics did not surprise the medical community for long: although patients with gastrointestinal diseases took a lot of antibacterial and anti-inflammatory drugs, they were also useful, and their condition became more and more serious, so that acute gastrointestinal diseases turned into chronic gastrointestinal diseases and even intractable gastrointestinal diseases. \x0d\ Probiotics are a kind of bacteria living in human intestines, with Bifidobacterium and Lactobacillus as the main representatives. Because they can form a biological barrier in the intestine, repel and inhibit harmful bacteria, produce substances beneficial to the human body, promote digestion and absorption and intestinal peristalsis, and enhance human immunity, they have won the reputation of "human friends". So, who needs to add nine concentrates? \x0d\ 1。 Caesarean babies, premature babies, low birth weight babies, artificially fed babies: These children have low immunity and catch a cold or enteritis every three days. \x0d\2。 For people with diarrhea or constipation, western medicine and traditional Chinese medicine have little effect. Whether it is infectious diarrhea caused by bacteria, viruses and protozoa or non-infectious diarrhea, there is intestinal flora imbalance. Nine strains can be effective! \x0d\3。 Cancer patients receiving chemotherapy or radiotherapy: Chemotherapy drugs and radiotherapy will kill probiotics and lead to intestinal flora imbalance. It is characterized by abdominal distension, constipation, nutrient loss and toxin absorption, which not only affects the recovery of patients, but also may force chemotherapy and radiotherapy to be interrupted. \x0d\4。 Patients with liver cirrhosis and peritonitis: There is not only flora imbalance, but also lipogenic endotoxemia with different severity. Supplementation of probiotics can inhibit the production of amine by spoilage bacteria in the intestine, reduce the acidity in the intestine and the endotoxin content in the blood. \x0d\5。 Enteritis patients: Although the cause of ulcerative colitis is not clear, probiotics supplementation can achieve a certain effect. \x0d\6。 Dyspepsia: Functional dyspepsia is characterized by recurrent or persistent symptoms, such as abdominal distension, anorexia and heartburn. And there are no diseases of stomach, liver, gallbladder and pancreas. Probiotics can promote digestion. Lactose intolerance ("milk allergy"): when lactase is deficient in nature or due to intestinal infection and malnutrition, \x0d\7. Lactose cannot be decomposed, leading to abdominal distension and diarrhea. Probiotics can help decompose lactose in milk and promote the absorption of nutrients in milk. \x0d\8。 People who lack physical activity for a long time need to supplement probiotics because of their small amount of activity and weak gastrointestinal peristalsis, which leads to indigestion, fatigue and intestinal discomfort. Of course, healthy people often supplement probiotics, which can promote the absorption capacity of the intestine and always maintain a balanced nutrition. \x0d\9 Middle-aged and elderly people: Probiotics such as Bifidobacterium in human intestine will decrease with age. Supplementing probiotics can be used as a health care way for the elderly.
