Symptoms of lactose intolerance in newborns

Neonatal lactose intolerance is mainly manifested as diarrhea, abdominal distension, abdominal pain, borygmus and other symptoms. 1. Diarrhea This is a common and prominent symptom of lactose intolerance. Due to insufficient or lack of lactase activity in the intestinal tract of newborns, lactose cannot be effectively decomposed. Lactose that has not been digested is fermented by bacteria in the intestinal tract, producing a large amount of gas and short-chain fatty acids, etc., resulting in increased osmotic pressure in the intestinal tract and a large amount of water entering the intestinal tract, thus causing diarrhea. The stool is usually yellow or green, thin paste or egg-flower soup, which may be accompanied by foam and sour smell. 2. Abdominal distension The gas produced by undigested lactose fermentation accumulates in the intestine, causing abdominal distension. The abdomen of the newborn may be significantly swollen and feel full. 3. Abdominal pain Abnormal fermentation and osmotic pressure changes in the intestine may stimulate the intestine and cause abdominal pain. Newborns may appear crying, irritability and other manifestations, especially after eating. 4. Intestinal sounds will be produced when the gas and liquid flow in the intestine, and the sound of purring in the stomach can be heard. When the above symptoms are found in newborns, they should seek medical attention in time, conduct relevant examinations to confirm diagnosis, and take corresponding treatment measures under the guidance of doctors, such as adjusting feeding methods, using lactase preparations, etc. At the same time, parents should pay attention to observe the changes in symptoms of newborns, keep the buttocks of newborns clean, and prevent complications such as red buttocks caused by diarrhea.
