Are lactic acid bacteria beneficial for enteritis

Lactic acid bacteria are usually beneficial for patients with enteritis, as they help regulate the balance of gut microbiota and alleviate inflammatory reactions. Enteritis may be caused by factors such as infection, immune abnormalities, and improper diet. Moderate supplementation of lactic acid bacteria can improve the intestinal microenvironment, inhibit the growth of harmful bacteria, enhance intestinal barrier function, regulate immune response, and promote mucosal repair.

1. Improving intestinal microenvironment

Lactic acid bacteria can ferment to produce short chain fatty acids such as lactic acid, reduce intestinal pH, and create an acidic environment that is not conducive to the survival of pathogenic bacteria. Patients with enteritis often have dysbiosis in their gut microbiota. Supplementing with lactic acid bacteria can increase the number of beneficial bacteria such as bifidobacteria, reduce the proportion of opportunistic pathogens such as Escherichia coli, and help restore the balance of gut microbiota.

2. Inhibition of harmful bacterial growth

Antibacterial substances such as bacteriocins and hydrogen peroxide secreted by lactic acid bacteria can directly inhibit the proliferation of intestinal pathogens such as Salmonella and Clostridium difficile. For infectious enteritis, lactic acid bacteria compete to occupy space and prevent pathogens from adhering to the intestinal mucosa, reducing the damage of bacterial toxins to the intestine.

3. Enhancing intestinal barrier

Lactic acid bacteria can promote the expression of tight junction proteins in intestinal epithelial cells, reduce intestinal mucosal permeability, and prevent endotoxin and pathogen translocation. Chronic enteritis patients often experience intestinal leakage, and supplementing with lactic acid bacteria can repair damaged physical barrier function and reduce the risk of systemic inflammatory response.

4. Regulating immune response

Lactic acid bacteria balance Th1/Th2 immune response and reduce the release of pro-inflammatory factors such as TNF - α by activating dendritic cells and regulatory T cells. For autoimmune intestinal diseases such as ulcerative colitis, specific strains can alleviate intestinal tissue damage caused by excessive immune activation.

5. Promote mucosal repair

Some lactic acid bacteria can stimulate intestinal epithelial cell proliferation, accelerate ulcer healing, and increase mucin secretion to protect the intestinal wall. Supplementing lactobacillus to patients with radiation enteritis or antibiotic associated enteritis can shorten mucosal repair time and improve symptoms such as diarrhea and abdominal pain.

When choosing lactobacillus products for enteritis patients, it is recommended to prioritize the use of clinically validated strains such as Bifidobacterium and Lactobacillus acidophilus, and avoid consuming them on an empty stomach to reduce the damage of gastric acid to live bacteria. Low calorie diet can be combined with daily life, and the intake of spicy and stimulating foods should be restricted. During acute attacks, it is necessary to follow medical advice and cooperate with medication treatment. Attention should be paid to taking live bacterial preparations and antibiotics with a two-hour interval to avoid strain inactivation. If symptoms such as rectal bleeding, persistent fever, or weight loss occur, seek medical attention promptly to investigate severe intestinal lesions.
