Congenital lactose intolerance

Congenital lactose intolerance: This is a disease different from congenital lactase deficiency and belongs to autosomal dominant inheritance. After the start of feeding, fulminant diarrhea, acidic stool with watery bubbles, and diarrhea. Can cause vomiting, dehydration, renal tubular acidosis, diglycosuria, amino acid urine, cataracts, liver and brain damage, which can cause death if diagnosed late. After stopping breastfeeding, diarrhea disappeared and lactose-free and amino aciduria disappeared. After the undecomposed and absorbed lactose enters the colon, it is fermented by the bacteria present in the intestine into small molecule organic acids such as acetic acid, propionic acid, butyric acid, etc., and produces some gases such as methane, H2, CO2, etc. Those who are reabsorbed by the colon, but not absorbed or lactose that has not been decomposed, can cause bowel sounds, bloating, abdominal pain, exhaust, discomfort, and diarrhea. Some people also have belching and nausea. These symptoms are called lactose intolerance. Symptoms of lactose intolerance vary widely. Severe lactose intolerance occurs more than 30 minutes to several hours after ingesting a certain amount of lactose. Lactose intolerance has a greater impact on infants and young children, and it is accompanied by diaper rash, vomiting, and stunted growth. Adults sometimes have nausea. The number and severity of intolerance symptoms are related to many factors, such as lactase activity in the small intestine, the amount of lactose consumed, and whether other types of food are consumed at the same time.
