Is It Possible To Develop Lactose Intolerance
Found in milk. Lactose is a large sugar molecule that is made up of two smaller sugar molecules, glucose and galactose. In order for lactose to be absorbed from the intestine and into the body, it must first be split into glucose and galactose. The glucose and galactose are then absorbed by the cells lining the small intestine. The enzyme that splits lactose into glucose ...Read more
Yes: Many adults cannot tolerate dairy products, and this trait is more common in some racial groups. ...Read more
Yes: When taken with meals containing milk sugar lactose, the enzyme lactase found in those pills helps to digest the milk sugar lactose into glucose and galactose. The pills need to be taken at the time of the meal, not before and not after- in order to work. Take in the directed amount based on the amount of milk in the food. ...Read moreSee 1 more doctor answer
2 choices: You treat this issue by #1 avoiding all products with lactose or #2 take supplemental lactase enzyme (lactaid and others).There are milk products available that have the enzyme added and there are milk substitutes (almond ; soy) that contain no lactose. Some milk based products (cheddar cheese ; yogurt) that are low enough in lactose content that they don't trigger symptoms. ...Read more
A forever problem: Lactose intolerance is genetically based (please see my earlier answer), & is "forever." of course, some people with the condition have higher threshold for tolerating at least a certain amount of lactose. Also, replacement of lactase (the enzyme that breaks lactose down) is over-the-counter, can permit better tolerance of ingested lactose. Minimize lactose-containing foods unless lactase is taken. ...Read more
Avoid dairy products: The simplest way is to eliminate all diary for one week: milk, ice cream, cheese, etc. And see if the symptoms go away. Then try adding a small amount of dairy products, such as a glass of milk each day for a week. If symptoms of abdominal pain, bloating and gas return, you may have lactose intolerance. Talk to your physician, to get more suggestions to evaluate or treat your symptoms. ...Read moreSee 1 more doctor answer
Dairy Products: The principal symptom of lactose intolerance is an adverse reaction to products containing lactose (primarily milk), including abdominal bloating and cramps, flatulence, diarrhea, nausea, borborygmi (rumbling stomach) and vomiting. These appear thirty minutes to two hours after consumption. Lactaid can help with this if you do have it. Some people develop it after a course of antibiotics. ...Read more
Avoidance: Lactose intolerance is the inability of the gut to digest the disaccharide lactose. There are replacement enzymes you can take orally. The effectiveness varies. Avoidance of lactose remains the primary treatment. In general, it takes a fair bit of lactose to induce symptoms. ...Read moreSee 1 more doctor answer
Yes, comes with age: The great majority of the world's population becomes lactose intolerant with age (except northern europeans), because people produce less and less lactase enzyme and will not be able to digest milk sugar. Lactose intolerance can come on more suddenly after diarrhea. Taking lactase (lactaid tablets) can help a lot. We humans are the only mammals who keep drinking milk after weaning off the breast. ...Read moreSee 1 more doctor answer
Sudden lactose intol: Defects in lactose absorption can be acquired (due to inflammatory conditions of the intestine*) or congenital. Adult lactase deficiency (hypolactasia) is autosomal recessive (ar) & present in >75% of non-caucasians & 20% of caucasians. Congenital lactase deficiency (ar) is acute watery diarrhea in infants. *see your doctor for evaluation if your lactose intolerance is indeed of sudden onset. ...Read more
