The incomplete digestion of lactose by people who do not have enough lactase. Symptoms may or may not occur. A condition where symptoms such as gas, bloating and diarrhea occur after a standard lactose tolerance test. Lactose maldigestion is more common among adults of African, Asian, native North American or Oriental descent. The condition is rare in infants and less common in children than adults.
Some people can digest more lactose than others.
Some people can digest a glass of milk without any difficulty, especially when consumed with a meal, whereas others can have symptoms of maldigestion with much smaller amounts of milk. If it is temporary the body will be able to digest lactose again after it recovers. If you think you might have lactose maldigestion, ask your doctor to order tests for an accurate diagnosis. Because this test uses very large amounts of lactose it can make the problem appear to be worse than it is. So for taste and good nutrition, try to include milk and milk products in your daily diet.
