Lactose Intolerance

Lactose intolerance is the inability to digest certain sugars in milk and dairy products. In some people, this can cause mild to severe stomach upset.

343 Questions

What is lactose intolerance?

General meaning:

Lactose intolerance is results of an inability to digest or to metabolize lactose.

  • due to missing or defective enzymes (inborn error of metabolism)

Flow:

  1. ingested milk products
  2. buildup of dissacharides because deficiency of lactase in the intestinal villi.
  3. so, lactose cant be degraded to galactose and glucose
  4. cant be absorbed in to the bloodstream from the villi
  5. lactose will accumulated
  6. producing H2, CO2 and organic acids.
  7. digestive problems: bloating and diarrhea

Note that the common definition for "lactose intolerance" excludes infants. Virtually all human infants (indeed all mammal infants) are able to digest lactose, as it is a key ingredient in gaining sustenance from their mother. Infants not able to digest lactose are much more rare (and is a serious condition).

Normally, mammals lose the ability to digest lactose shortly after entering childhood (in humans, somewhere between 3 and 5). However, a mutation in certain human populations somewhere around 20,000 BCE enabled those people to continue to consume milk for their entire life. So, in reality, "lactose tolerance" is the genetic aberration (though, a beneficial one).

Which conditions and diseases cause lactose intolerance?

Following is a list of causes or underlying conditions that could possibly cause Lactose Intolerance: * Chronic digestive diseases * Crohn's disease * Coeliac's disease * Gastroenteritis * Inflammatory bowel diseases * Intestinal injury

What are the different types of baby formula available?

All baby formula attempt to replace breast milk. Some special kinds of formula are available if the baby has special dietary requirements. Basic milk based formulas are made from cow's milk. For those babies who are lactose intolerant, special cow's milk formulas are available. Soy milk formulas can be substituted both for lactose intolerant babies, or for babies who are raised to be vegan. The doctor may prescribe yet other specialty formulas for babies that do not tolerate soy or milk products.

Is Natasha Obama lactose intolerant?

There have been some blog posts making the claim that Sasha (she prefers to be called Sasha, rather than her birth name of Natasha) is lactose intolerant, but I have not seen any verification of this. However, if it were true, it would not be surprising. A number of African-Americans (but not all) suffer from some degree of lactose intolerance; Sasha may indeed be one of them.

What do pediatricians recommend when lactose intolerance is suspected in infants?

When lactose intolerance is suspected in infants and young children, many pediatricians recommend simply changing from cow's milk to soy formula and watching for improvement.

Why are most lactose intolerant individuals able to eat table sugar?

Most lactose intolerant individuals can consume table sugar because it is composed of glucose and fructose, which do not contain lactose, the sugar found in milk. Lactose intolerance is due to the inability to properly digest lactose due to a deficiency in lactase, the enzyme responsible for breaking it down. Since table sugar doesn't contain lactose, it can be safely consumed without causing digestive issues for those with lactose intolerance.

Why are asian's lactose intolerance?

When Asians were evolutionally developing, they mostly ate vegetables. So therefore, their metabolism is not as accustomed to processing high levels of protein, fat, and their glucose levels are eaiser to raise and drop. And in China, milk isn't as popular. So therefore, I assume, more Asians develop lactose intolerence.

By the way, an Asian wrote this. :)

And I'm not a dietician, but I'm just making a logical assumption.

Does lactose intolerance affects the brain?

Lactose intolerance primarily impacts the digestive system, causing symptoms like bloating and diarrhea when lactose-containing foods are consumed. While it does not directly affect brain function, the discomfort and distress from gastrointestinal symptoms can lead to mood changes, anxiety, or decreased quality of life. Additionally, some studies suggest that inflammation or gut health issues related to lactose intolerance could indirectly influence brain health, though more research is needed to fully understand this connection.

Is pesto lactose free?

Yes.

However if the pesto recipe has cheese which is classed as non-vegetarian i.e curdled from the stomach of an animal then strictly speaking no.

Can lactose intolerant people eat egg whites?

Yes, lactose intolerant people can eat egg whites because egg whites do not contain lactose. Lactose intolerance is specifically related to the inability to digest lactose, a sugar found in milk and dairy products. Therefore, egg whites are a safe protein source for those who are lactose intolerant.

Is there a particular age range for lactose intolerance?

Lactose intolerance can develop at any age, but it is most commonly diagnosed in adolescents and adults. Many individuals experience a decrease in lactase enzyme production after weaning, with symptoms often emerging in late childhood to early adulthood. However, some can remain tolerant to lactose into their teenage years or even adulthood. The prevalence of lactose intolerance varies widely among different ethnic groups and populations.

Is burning or sore muscles a symptom of lactose intolerance?

Burning or sore muscles are not typical symptoms of lactose intolerance. Lactose intolerance primarily causes gastrointestinal symptoms, such as bloating, gas, diarrhea, and abdominal pain after consuming lactose-containing foods. Muscle soreness may result from exercise, dehydration, or other factors, but it is not directly linked to lactose intolerance. If you experience muscle pain along with gastrointestinal issues, it may be worth consulting a healthcare professional for a proper evaluation.

What can be done to work against such prejudice and intolerance?

To combat prejudice and intolerance, it is essential to promote education and awareness about different cultures, identities, and experiences. Encouraging open dialogue and empathy can help individuals understand diverse perspectives and dismantle stereotypes. Community engagement initiatives that celebrate diversity and foster inclusion can also play a pivotal role in building connections among different groups. Finally, advocating for policies that protect marginalized communities and promote equality is crucial in creating a more just society.

Does candesartan contain lactose?

Candesartan does not contain lactose as an active ingredient. However, some formulations or generic versions of the medication may include lactose as an inactive ingredient or filler. If you have lactose intolerance or allergies, it's important to check the specific formulation or consult with a pharmacist or healthcare provider.

How lactose is formed from monosaccahrides?

Monsaccharides are a simple for a sugar and can have a sweet taste. They are usually colorless and water-soluble. Monosaccharide includes glucose and galactose. Lactose is made from both of those at its simplest forms.

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.

What are lactose intolerance symptoms?

People who are lactose intolerant are not able to process lactose in the body. Lactose is a substance that is commonly found in milk products. Older adults and people of certain ethnic groups are more prone to develop lactose intolerance. Symptoms for lactose intolerance include abdominal pain, abdominal bloating, gas, diarrhea. Those who experience any of the symptoms mentioned should consult with their doctor for further advice on dealing with and controlling lactose intolerance.

Is height and weight significant in lactose intolerance?

Adults need a particular enzyme in their stomach to tolerate lactose. Babies are born with that enzyme. It turns off automatically in a number of children when they get to be about six years old. As a result they become lactose intolerant. Height and weight have nothing to do with lactose intolerance but the lack of an enzyme. Some people lactose intolerant people drink milk with a bacterium added which adds that enzyme. Others eat milk in the form of cheese or yogurt.

I moved away and my lactose intolerance went away I could eat milk products now I am back home and it bothers me again why?

Sometimes stressful situations trigger reactions that wouldn't otherwise occur. You may be secreting different amounts of stomach fluids when you are home that don't react as well to milk.

Why are people lactose intolerent?

All mammals, including humans, are fed milk, by their mothers, when they are infants. all infants bodies produce an enzyme called lactase, that digests lactose, the kind of sugar found in milk. As they grow, animals and many people stop producing lactase and can no longer digest milk. they become lactose intolerant. people whose ancestors came from areas where dairy foods have long been part of the diet, such as northern and western Europe, are less likely to become lactose intolerant.

If your lactose intolerant and you drink milk on purpose to get skinny is that unhealthy?

If you are lactose intolerant and drink milk you will have diarrhea. Prolonged diarrhea causes dehydration. Thus the majority of weight loss will be only water weight.
