The patient drinks a beverage containing lactose and the breath is analyzed at regular intervals. If undigested lactose in the large intestine (colon) is fermented by bacteria, various gases are produced.
No, undigested food is not part of body cells. Undigested food consists of components that the body was unable to break down and absorb during the digestion process. The body processes undigested food differently, such as excreting it through feces.
When someone is lactose intolerant it means they don't produce any/enough lactase enzyme in the small intestine. Without the enzyme, lactase the lactose is not broken down and doesn't go into the bloodstream, it stays in the small intestine where bacteria respires, to try and break it down. The presence of undigested lactose increases water potential and therefore leads to diarrhoea.
That depends if you're lactose intolerant or not. If you are then you end up with undigested food in your gut, which may lead to nausea, diarrhea, or vomiting. If you're not intolerant, then you just get fat.
No don't drink milk.Even if you don't suffer from lactose intolerance, it might be a good idea to avoid dairy products for a while after suffering from a bout of diarrhea. Diarrhea can cause a lessening of the amount of the enzyme lactose. Lactose is needed in order for the body to digest lactose, the sugar found in dairy products. If this "milk sugar" goes undigested, it can result in further symptoms of gas, bloating, nausea and diarrhea. Here are some common lactose-containing foods:ButterCheeseIce creamMilk
Their body can't absorb lactose...There are enzymes in your small intestine which break down lactose called lactase. Lactase breaks down lactose into galactose and glucose so your body can then absorb it.
The elimination
undigested food
No, lactose does not spontaneously break down in water or alcohol. Lactose is broken down by the body. In those with lactose intolerance, it is not always broken down correctly and is expelled from the body.
Outside your body.
Large intestines.
