Seems that they and their doctors merely tried the elimination diet and since the symptoms went away, they automatically assumed that they were indeed lactose intolerant. In many cases the doctors chose to test the patient for lactose intolerance by giving them a mixture of 50g of lactose in water to drink after fasting for at least 8 hours. This is like drinking a quart of milk on an empty stomach, something that would make those of us who are not lactose intolerant have a bad reaction to.

Newer testing techniques such as the breath hydrogen/methane test can be used to differentiate between what is known as a lactose maldigester and someone who is lactose intolerant. The typical maldigester can only absorb a certain amount of lactose but may never display any of the symptoms of someone who is lactose intolerant such as diarrhea or nausea.

The hydrogen/methane breath test makes use of the fact that the fermentation of carbohydrates by the colonic bacteria in the body should be the only source of hydrogen in the human body. Given this fact the hydrogen that is produced by the fermentation of lactose then enters the blood stream and finally ends up being expelled from the body through exhaling. Thus if the hydrogen level in the breath shows a significant rise after drinking a glass of milk following  fasting then the patient is more likely to suffer from lactose maldigestion rather than intolerance. This is significant in that if the test shows maldigestion but the symptoms of intolerance persist further testing needs to be done to find out the root cause of the symptoms.

However there are of course some foods that contain dairy that you can still eat and enjoy in small quantities that may not wreak havoc on your body. Research has found that many lactose intolerant people can eat fermented milk products such as cheese and yogurt without suffering the same symptoms that they get if they drink a glass of milk.

The reason behind this is that since these products are made from fermented milk they have different levels of lactose in them. For instance many yogurts contain a lactase enzyme in them that is a product of the bacterial cultures developed during the manufacturing process, be aware though that some brands of yogurt add milk solids back in after fermentation which totally negates the advantages of the lactase.

Cheese on the other hand while it is also a fermented milk product contains little or no lactose in it after fermentation so for many people who would otherwise be lactose intolerant, cheese can be very much on the menu and a good source of calcium.

Another very popular alternative to cow’s milk for those who are lactose intolerant is goat’s milk. While it still contains lactose, researchers think that because it is much easier to digest the intestines absorb it much more easily leaving behind little or no residue to ferment in the colon which is the chief cause of the symptoms associated with lactose intolerance.

Goat’s milk and goat’s milk products make an excellent substitute for anything that is made with cow’s milk, it contains plenty of calcium in fact it has 13% more calcium than cow’s milk along with 25% more vitamin B-6 and 47% more vitamin A and more of many other essential vitamins and minerals. Lastly there are no bovine growth hormones in goat’s milk making it the perfect alternative to cow’s milk for everyone.

If your doctor has suggested you have a hydrogen breath test there will be a few things you will need to do to prepare for this test. You may not have had a colonoscopy, barium enema, or any other test that requires a bowel prep to be done since this prep will cleanse the bacteria in the bowel. This bacteria must be present to do the hydrogen breath test, so you will need to wait 4 weeks after these procedures to have this test done.

During the 4 weeks prior to the tests you may also not have taken any antibiotics or Pepto Bismol. 24 hours prior to the test you should not smoke and the day of the test you should abstain from chewing gum, using mouthwash, or toothpaste and you will be asked to fast for 8 hours prior to the test as well.

In the case of lactose malabsorption testing basing readings of hydrogen levels are taken of the patient’s breath. The patient then drinks a liquid that is pure lactose, approximately 20 to 25 g. The patient’s breath is then measured every 15 to 30 minutes for about 3 hours.  Doctors are looking for levels of hydrogen that are 20ppm above the lowest preceding value at the beginning of the test. Levels above this mark will result in a diagnosis of lactose intolerance.

Methane levels are also measured, as some patients may produce exaggerated levels of methane rather than hydrogen and some patients may produce both gasses. With methane gasses any level that is 12 ppm higher than the original value is considered a positive diagnosis for lactose intolerance. For a patient that produces both gasses, the two values are added together and averaged, with 15 ppm being the number that most doctors are looking for, for this combined value.

Much of the research studying those with lactose intolerance and bone health has been conflicting, with some studies showing that decreased calcium intake from lactose intolerance may increase ones risk of osteoporosis with other studies showing that it does not. That being said, most experts agree that those with lactose intolerance show pay close attention to how much calcium they are getting in an effort to maintain healthy bones.

Some dairy sources may be easier to digest than others and because only rarely does a person’s body completely stop making lactase most people can tolerate small amounts of lactose at any given time. The trick is to choose the right types of dairy and to eat it in much smaller amounts broken up during the day, giving your body the opportunity to produce enough lactase to digest the lactose you consume. Dairy products you might try are yogurt, buttermilk, and aged cheeses such as cheddar or swiss these dairy products contain less lactose than milk and may be better tolerated.

While the best source of calcium is dairy, it is not the only source of dairy so if you need to limit your dairy intake. You can get your calcium from other sources such as dark leafy greens, oily fish with bones, and calcium fortified foods. You can also supplement your calcium with a good quality vitamin supplement; one that provides about 1000mg daily will provide you will the calcium that you need. Vitamin D is also important for bone health and should also be supplemented.

Bone health depends on careful monitoring of your calcium levels, and eating a healthy varied diet that includes plenty of other sources of calcium. A balanced approach, combine with sensible choices such as plenty of exercise and not smoking is the best defense for bone health.

There are several tests that can be used to diagnose a child with lactose intolerance many of them are the same tests used on adults but one is designed especially for infants and young children called the stool acidity test. In the stool acidity test a sample is tested to measure the amount of acid in the stools. Undigested lactose is fermented by bacteria in the large intestine; this creates lactic acid and other acids that can be detected in the stools. Doctors may also be able to detect glucose in the stools from the undigested lactose.

For older children the same tests that are used on adults may be used. These tests are not used on very young children because the higher amounts of lactose used to produce results may be harmful to small children. In the lactose tolerance test a child is given a liquid containing lactose, their blood is then tested to see if their blood glucose rises, if it does this means the small intestine is absorbing lactose, in lactose intolerant children the blood glucose level will not rise. This test requires several blood draws so it may not be ideal for young children.

A final test, the hydrogen breath test does not require blood draws so it may be a better choice for a younger child. In this test a child again drinks a lactose drink, after having the amount of hydrogen measured in their breath. The hydrogen level is then measured every fifteen minutes thereafter, to check for large increases in hydrogen levels which will indicate that the lactose did not digest properly.

Regardless of what test for lactose intolerance you child has if they test positive they will be placed on a lactose reduced or lactose free diet. A careful diet with plenty of calcium alternatives or supplements is the key to reducing your child’s symptoms and ensuring good health.

For most individuals the symptoms lactose intolerance will not be severe enough to have caused vitamin deficiencies nor will they need to reduce dairy intake enough to cause issues with their calcium intake but for those with severe lactose intolerance, supplementation with extra vitamins may be necessary to make sure you are getting proper nutrition.

The most important supplement for you to be concerned with of course is calcium, because your diet is restricted in dairy products chances are good that you may not be getting enough of this very important nutrient. Taking 500 – 1000 milligrams of calcium a day should be enough for anybody including post menopausal women. Calcium is essential for strong bones and will help to prevent osteoporosis.

The other vitamin you may not be getting enough of is Vitamin D, which is usually supplemented in the milk you drink, but if you are not drinking milk you may not be getting enough. Vitamin D deficiency is associated with muscle problems, heart disease, a loss of mental acuity, and fertility problems. Adults need a minimum of 400 international units per day.

If your lactose intolerance that is a secondary condition to another disease such as celiac disease you will need to ask your doctor to do blood test to check your vitamin B and iron levels as they may also be low.

Most people will benefit from a general multi-vitamin and if your lactose intolerance has been untreated for some time it is possible that the intestinal distress caused by chronic diarrhea may leave you vitamin deficient, in such cases a good multi vitamin and removing the offending foods will quickly remedy the problem.

There are a few things that you can try at home that may help you to better digest dairy for those days when you just have to have that glass of milk or bowl of ice cream. Cocoa has been found to reduce the symptoms of lactose intolerance, it is thought that cocoa will slow the stomachs emptying reducing the rate at which lactose reaches the colon. Non fat chocolate or cocoa is best, as the high fat content can aggravate the symptoms.

If you do not like chocolate milk you can try adding powdered lactase directly to your milk, let it sit overnight and in the morning your milk will have half the lactose it had the day before and your milk will have a pleasant sweet taste to it, since the lactase will break the lactose down into glucose.

Many people find that if they consume their dairy with a meal that there are little or no symptoms. Doctors believe one of the key factors in lactose intolerance is the rate at which the stomach empties; a full meal will slow that rate of emptying and thus slow the rate at which lactose enters the small intestine giving your intestine more time to digest the lactose.

Consuming fermented dairy products such as yogurt, buttermilk and hard cheese tends to be much easier on the intestines than milk is, making it possible for the lactose intolerant to consume these dairy products. A good example is yogurt, since the organisms in yogurt produce lactase, they be much better tolerated by those that are lactose intolerant.

Lactose intolerance can be a miserable and painful condition but it is relatively harmless in its adult form. Caused by the decline of the enzyme lactase, this condition is actually quite common and considered a normal part of aging. Lactose intolerance symptoms include diarrhea, nausea, bloating and gas, all of which can be symptoms of any number of gastrointestinal diseases. In addition to this, lactose intolerance can be a secondary symptom of other diseases meaning that it can mask an underlying disease such as celiac disease.

One of the most common diseases that are confused to lactose intolerance is Irritable bowel syndrome.  IBS has the same symptoms as lactose intolerance and can be triggered by the foods you eat however there is a number of different foods that can trigger IBS and the treatments for Irritable bowel syndrome are different than the treatment for lactose intolerance.

It is important to check for food allergies as well when a problem with milk is discovered while most food allergies have some similar symptoms to lactose intolerance, milk allergies also usually have symptoms that affect the skin and respiratory system as well but this is not always the case. Because an allergy to milk is to a different substance in the milk than a lactose intolerance it is important to distinguish between the two, since avoiding lactose will not necessarily help you avoid casein which is the most common trigger of milk allergies.

Inflammatory bowel disease has also often been mistaken for lactose intolerance the symptoms again the same, but the inflammation caused by this disease can cause all sorts of problems such as weight loss, dehydration and malnutrition and cause severe complications with many different organs and body systems.

Most of these diseases can be easily diagnosed by your doctor including lactose intolerance. Getting tested will rule out more severe conditions but at the same time it will make sure you get the appropriate treatment for the condition you have.

Whether you will be lactose intolerant depends on your genes, either you have the gene that keeps lactase production turned on or you do not. This gene mutation as it has been described is fairly new in terms of human history first showing up about 9,000 years ago.

Another myth about lactose intolerance is that you do not need to be tested; you can tell if you have it or not by your symptoms.  Lactose intolerance symptoms are very similar to many other symptoms including milk allergies, celiac disease and other truly serious diseases. Self diagnosis is dangerous, if you think you may have lactose intolerance see a doctor and obtain a diagnosis so you know for sure.

There is no cure for lactose intolerance unless it is a secondary condition to a primary disease or infection. Primary lactose intolerance again is a normal state for an aging human body, increasing lactase production is just not possible.

The federal government requires labeling for lactose on food package is another myth, since lactose intolerance is not a life threatening serious disease; it seems the government simply does not take it very seriously. In addition to that the FDA has been quoted as saying that lactose intolerant consumers know how to avoid milk and milk products so do not need to be advised in labeling of the presences of lactose. Since most lactose intolerant consumers must measure and balance their consumption of lactose it becomes important for them to have some idea about the amount of lactose in a product.

Finally the last myth about lactose is that if a product states that it is 100% lactose reduced it is not always so, often these products still contain a small amount of lactose in these products, for those that are highly sensitive to lactose this can be a bad thing, but for most lactose intolerant individuals this is usually not a problem.

Lactose is the sugar in milk that needs the enzyme lactase to break it down so that it can be absorbed by the body. Babies usually produce this enzyme in abundance but after the age of weaning the production of lactase naturally declines as our dependence on milk declines. This is actually a normal process although many of us now possess a gene mutation that allows lactase production to continue past this time. Lactose intolerance while miserable for many is not a serious condition, but merely your body’s reaction to undigested food. Most people will experience diarrhea, bloating and gas as a response to undigested lactose.

Casein is one of the proteins found in milk and while one can be intolerant to casein, it is casein allergies that we hear about most. Casein allergies are more serious than lactose intolerances, and symptoms can be far more invasive than those of lactose intolerance. Symptoms can include eczema, hives, gastrointestinal symptoms similar to those of lactose intolerance, and asthma. Those that have an intolerance or allergy to casein are also at risk for anaphylactic reactions where the immune system floods the body with chemicals and the body can go into shock.

For those with lactose intolerance it is relatively simple to avoid lactose, the vast majority of people can tolerate small amounts of lactose, and only need to avoid things such as milk and possibly other dairy products. It is not necessary for those with lactose intolerance to avoid casein and most lactose intolerant people can consume milk with the lactose removed. Casein is much more difficult since it tends to be in more products and for those that have a casein sensitivity problem even small amounts of casein can cause issues. For these people no dairy product or byproduct is acceptable since it is likely to contain trace amounts of casein.
