How is lactose intolerance measured in children?
To identify lactose intolerance in children and adults, the hydrogen breath test is used to measure the amount of hydrogen in the breath.
What does the breath testing for lactose intolerance involve?
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.
Does lactose intolerance cause bad breath?
no. as usually if not caused by gum disease, bad breath is caused by a gas from the stomach. someone who is lactose intolerant would have bad breath if consuming dairy produce as it would cause a stomach upset
How can you determine if your child is lactose intolerant?
To determine if your child is lactose intolerant, you can observe symptoms such as bloating, gas, diarrhea, or stomach cramps after consuming dairy products. You can also consult a healthcare provider for tests like a lactose intolerance breath test or a lactose tolerance test.
How can I determine if my child is lactose intolerant?
To determine if your child is lactose intolerant, observe if they experience symptoms like bloating, gas, diarrhea, or stomach cramps after consuming dairy products. You can also consult a healthcare provider for tests such as a lactose intolerance breath test or a lactose tolerance test.
How can parents determine if their child is lactose intolerant?
Parents can determine if their child is lactose intolerant by observing symptoms such as bloating, gas, diarrhea, or stomach pain after consuming dairy products. They can also consult a healthcare provider for tests like a lactose intolerance breath test or a stool acidity test.
What is the test used to check for hydrogen?
The test used to check for hydrogen is the hydrogen breath test. In this test, a person drinks a solution containing a specific sugar (e.g. lactose) and then breath samples are collected to measure the amount of hydrogen gas produced by bacteria in the intestines during the digestion process. Elevated levels of hydrogen gas can indicate malabsorption of the sugar.
How can you determine if your toddler is lactose intolerant?
To determine if your toddler is lactose intolerant, you can observe symptoms such as stomach pain, bloating, gas, diarrhea, or vomiting after consuming dairy products. You can also consult a pediatrician for further testing, such as a hydrogen breath test or stool acidity test.
where can i take a breathalyzer test before weight loss surgery?
I assume you are referring to a lactose breath hydrogen test? You will need to speak with your physician to see where you can get one done in your area, and if he feels it is necessary.
What is lactose intolerance and is it the same as a milk allergy?
Lactose intolerance is the inability to digest lactose, found in animal milk (including human milk, which, in fact, has about twice has much lactose as cow's milk). An enzyme called lactase is required to digest lactose. When this enzyme is missing, the following symptoms may occur: abdominal cramps, diarrhea, gas, a feeling of bloatedness. Symptoms may occur within an hour, or up to several days later. The intensity of symptoms varies widely. DIAGNOSIS Lactose intolerance can be self-diagnosed by eliminating milk and dairy products from your diet for two weeks, then reintroducing milk (a glass or two), and seeing what happens. Your doctor can administer a couple of tests to confirm lactose intolerance (basically involves drinking a sweet drink containing a lot of lactose on an empty stomach and monitoring blood levels of glucose -- no rise in glucose means the lactose is not being absorbed; the other involves checking breath levels of hydrogen). TREATMENT If you are diagnosed with lactose intolerance, you have a variety of options. Lactase is available by prescription (Lactaid), and can be added to milk (drops) or taken with food containing dairy products (tablets). Some people may have adverse reactions to this medication, however (in tablet form -- the reaction is believed to be allergic. Drops seem to be ok.). Lactose reduced milk and cheeses are available in some areas. Aged cheeses, yogurt and sour cream may be tolerable (most of the lactose has already been converted). You can find your level of lactose tolerance by either cutting out dairy products entirely and slowing working them back into your diet, or you can slowly eliminate them until you stop having difficulties. Tables indicating lactose content for milk and milk products are available. Some believe that lactose intolerance is, in fact, the human (and mammalian) norm, rather than an aberration, citing in support statistics that indicate most of the world's population is lactose intolerant (Europeans and those of European descent being the exceptions), and the tendency to lactose intolerance with increased age. MILK ALLERGY Milk allergy, on the other hand, involves an allergic reaction to one or more of the proteins in milk (casein, lactalbumin, lactoglobulins). An allergic reaction to milk may include: eczema, rash, mucous buildup, wheezing, asthma, rhinitis, pneumonia, anaphylaxis. The type and severity of symptoms varies widely. Because a true milk allergy may involve mast cells in the mouth and throat, it is possible to have an allergic reaction to milk or milk products before they are digested. It is possible to be both lactose intolerant AND allergic to milk. DIAGNOSIS The bad news is, diagnostic tests for milk allergy -- for food allergy in general -- are hit or miss. One source I have claims that a negative is accurate, but false positives are common. Another states that the extracts used in allergy tests tend to lose potency quickly so you might test negative on a test and STILL be allergic. Elimination diets are the best test you have available to you. If you suspect milk allergy, eliminate milk and milk products for two or more weeks, and see what happens. If you can convince your physician to conduct a double-blind test on you, you may be able to confirm the diagnosis. TREATMENT The worse news is, no cure is available -- avoidance, and symptom control via antihistamines, etc. are the best you can do. (For now, at least, this is true of all food allergy, at least according to the conservative medical community -- but research is ongoing. I have a reference to a study by the National Jewish Center for Immunology and Respiratory Medicine in Denver which claims successful desensitization to peanuts in people who had a life history of allergic reaction to them. There's a dim hope, at least.) [The National Jewish Center for Immunology and Respiratory Medicine in Denver has prepared a report about successful desensitization to peanuts in patients with a life history of allergic reaction to them. The address for that group is: National Jewish Center for Immunology and Respiratory Medicine, Public Affairs Department, 1400 Jackson Street, Denver, CO 80206 303-398-1079, 800-222-LUNG (5864)] Lactose intolerance is the inability to break down the sugar in milk, lactose. There are varying levels of lactose intolerance, based upon how much of the enzyme "Lactase" your body has. The more it has, the better the ability of your body to break down the sugar, and the more tolerance you have. Since cow milk is not a natural thing for humans to drink (nor any milk past age 2), it makes sense that people will develop primary lactose intolerance over their life time and it is not uncommon for adults to develop the symptoms of lactose intolerance which include but are not limited to; diarrhea, stomach cramps, bloating, gas and nausia. If a young child has any of these symptoms, contact their doctor, as it is possible to be born lacking lactase.

Lactose tolerance tests?
DefinitionLactose tolerance tests measure the ability of your intestines to break down lactose, a type of sugar found in milk and other dairy products.See also: Lactose intoleranceAlternative NamesHydrogen breath test for lactose toleranceHow the test is performedTwo common methods include:Lactose tolerance blood testHydrogen breath testThe hydrogen breath test is the preferred method. It measures the amount of hydrogen in the air you breathe out.You will be asked to breathe into a balloon-type container. Then, you will be asked to drink a flavored liquid containing lactose. Samples of your breath are collected at set time periods and the hydrogen level is checked. Normally, very little hydrogen is in your breath. But if your body has trouble breaking down and absorbing lactose, hydrogen levels increase.The lactose tolerance blood test looks for glucose in your blood. Your body creates glucose when lactose breaks down. For this test, several blood samples will be taken before and after you drink the lactose solution described above. For information on how a blood sample is obtained, see venipuncture.How to prepare for the testYou should not eat for 8 hours before the test. Avoid strenuous exercise for 8 hours before the test.How the test will feelThere should not be any pain or discomfort when giving a breath sample.When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.Why the test is performedYour doctor may order these tests if you have signs of lactose intolerance.Normal ValuesThe breath test is considered normal if the increase in hydrogen is less than 12 parts per million over your fasting (pre-test) level.The blood test is considered normal if your glucose level rises more than 30 mg/dL within 2 hours of drinking the lactose solution. A rise of 20-30 mg/dL is inconclusive.Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.What abnormal results meanAbnormal results may be a sign of lactose intolerance.A breath test result that shows a rise in hydrogen content of 12 parts per million (ppm) over your pre-test level is considered positive, and means you may have trouble breaking down lactose.The blood test is considered abnormal if your glucose level rises less than 20 mg/dL within 2 hours of drinking the lactose solution.An abnormal test should be followed by a glucose tolerance test to rule out a problem with the body's ability to absorb glucose.What the risks areVeins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.Other risks associated with having blood drawn are slight but may include:Excessive bleedingFainting or feeling light-headedHematoma (blood accumulating under the skin)Infection (a slight risk any time the skin is broken)ReferencesHogenauer C, Hammer HF.
