Causes, Symptoms, Treatment & Products. Lactose intolerance is the inability to completely digest lactose, the predominant sugar found in milk. If lactose is not absorbed properly, it ferments and this results in bloating, cramps, gas, flatulence, and diarrhoea amongst others. Lactose intolerance affects more than half of the world population. It may also the cause of baby colic. According to various studies, lactose intolerance accounts to more than half of wrongly diagnosed patients with irritable bowel syndrome (IBS). Lactose intolerance is the most common form of food intolerance; others include carbohydrate, fructose, and gluten. Lactose Intolerance can also be a side effect of gluten Intolerance. Lactose intolerance must not be confused with milk allergy, of which comparison details are listed below. What causes lactose intolerance? Milk contains lactose, a disaccharide made of two sugars joined together. Lactose is the carbohydrate naturally found in all kinds of milk, including human milk. It can also be used as an ingredient in some foods. Lactose intolerance, or dairy intolerance, is a digestive problem that means the body cannot digest sugars mainly found in milk called lactose. Dependable irritable bowel syndrome (IBS) causes, symptoms, support and treatment for digestive health sufferers, family and friends since 1987. Diet, Eating and IBS Symptoms. There are a variety of factors that affect IBS, and diet is just one of these. If other factors, such as stressors or hormonal changes. Diet for Lactose Intolerance What is lactose intolerance? Lactose (milk sugar) intolerance results from an inability to digest lactose in the small intestine. Our body is not able to absorb lactose unless it is broken down into two sugars. So to get around this lactase present in the lining of the small intestine splits lactose so it could be absorbed. This is fermented by the bacteria living in the large intestine resulting in excess gas, stomach rumbling and bloating. Severe intolerance leads to diarrhoea and other symptoms. Who can get lactose intolerance? Lactase activity is normally high in babies, although baby colic may be caused by temporarily lactase deficiency (see baby colic). After the ages of 5- 6 lactase production starts decreasing in many individuals but the rate varies from one person to another and also between races. From the table below one can conclude that the majority of people in the world are lactose intolerant. Lactose Intolerance Around the World. Human Group% Lactose Intolerance. Caucasians. 10- 2. Mediterranean. 40- 5. Oriental. 90%American Blacks. African. 50%Aborigines. However there are other people irrelevant of what race or age they are that may develop lactose intolerance: Coeliac disease: this condition causes damage to the lining of the small intestine hence lactase is not produced. Small intestine surgery: may become unable to produce lactase anymore. Antibiotic treatment: may cause diarrhoea which damages lining of the small intestine temporarily reducing lactase production. Treatment can be accelerated with probiotics containing life bacteria. What are the symptoms? You probably know someone with lactose intolerance. Maybe that person is a family member, a friend, or you. It’s most common among Asian Americans, African. Lactose left in our digestive system causes extraction of fluids (water) from the body into the guts (same as when drinking sea water) by a process called osmosis. The combination of fluids and lactose in the digestive system is an attractive combination for the bacteria living in the large intestine that will digest lactose producing gases associated with. This can, however, be tricky because most processed food contains hidden lactose. Abstaining from milk and dairy is a better solution but this can almost be impossible. The best treatment to avoid the symptoms is by supplements of lactase enzymes. There are many commercially available lactase enzymes, but the best by far is Prolactazyme Forte that when tested at foodreactions. It continues to work for several hours after intake and unlike many others the body never gets used to it. It is fully derived from plants and also suitable for vegans. This is now available world wide from foodreactions. Buy Prolactazyme Forte now> > > There is also lactase enzyme in the form of liquid. This is handy to turn normal milk into lactose free saving you a lot of money. It is suitable for babies to avoid baby colic and ideal for those who like to drink milk or putting milk with cereals, tea or coffee for the breakfast etc. This is now also available at Food. Reactions. org. See the Products section for today's offers. How can I test for lactose intolerance? Lactose intolerance — Comprehensive overview covers symptoms, causes, diet and self-care. Lactose intolerance is the inability to break down lactose, a natural sugar. Learn about signs and treatment. The most common tests used to measure the absorption of lactose in the digestive system are the lactose tolerance blood test, the hydrogen breath test, and the stool acidity test performed on babies. These tests are performed on an outpatient basis at a hospital, clinic, or doctor's office. However, one can do a Homepage self- test in which after fasting for 1. If symptoms develop one can be certain he/she has lactose intolerance. Milk allergy is caused when our immune system thinks proteins found in milk are harmful, hence an immune response is triggered causing symptoms related to food allergy, such as rash, hives, swelling etc. However, some symptoms such as vomiting and diarrhoea can be common for both so it is important to read and understand the difference for better diagnosis. Lactose Intolerance & Milk Allergy Comparison. Lactose Intolerance. Milk Allergy. Causenot enough enzymes to breakdown the sugars, such as lactose consumed in foods. Agestarts later in childhood but most common in adults, may be temporarily present in the form of colic in babies. Symptoms affect the digestive system only: diarrhoeaabdominal bloatinggas and windstomach cramps. Some may experience vomiting. The magnitude of the above symptoms are inversely related to the amount of enzyme produced. Some people can produce less than others. Lactose intolerance Causes - Mayo Clinic. Causes. By Mayo Clinic Staff. Lactose intolerance occurs when your small intestine doesn't produce enough of an enzyme (lactase) to digest milk sugar (lactose). Normally, lactase turns milk sugar into two simple sugars — glucose and galactose — which are absorbed into the bloodstream through the intestinal lining. If you're lactase deficient, lactose in your food moves into the colon instead of being processed and absorbed. In the colon, normal bacteria interact with undigested lactose, causing the signs and symptoms of lactose intolerance. There are three types of lactose intolerance. Different factors cause the lactase deficiency underlying each type. Primary lactose intolerance. This is the most common type of lactose intolerance. People who develop primary lactose intolerance start life producing plenty of lactase — a necessity for infants, who get all their nutrition from milk. As children replace milk with other foods, their lactase production normally decreases, but remains high enough to digest the amount of dairy in a typical adult diet. In primary lactose intolerance, lactase production falls off sharply, making milk products difficult to digest by adulthood. Primary lactose intolerance is genetically determined, occurring in a large proportion of people with African, Asian or Hispanic ancestry. The condition is also common among those of Mediterranean or Southern European descent. Secondary lactose intolerance. This form of lactose intolerance occurs when your small intestine decreases lactase production after an illness, injury or surgery involving your small intestine. Among the diseases associated with secondary lactose intolerance are celiac disease, bacterial overgrowth and Crohn's disease. Treatment of the underlying disorder may restore lactase levels and improve signs and symptoms, though it can take time. Congenital or developmental lactose intolerance. It's possible, but rare, for babies to be born with lactose intolerance caused by a complete absence of lactase activity. This disorder is passed from generation to generation in a pattern of inheritance called autosomal recessive, meaning that both the mother and the father must pass on the same gene variant for a child to be affected. Premature infants may also have lactose intolerance because of an insufficient lactase level. Sept. 0. 2, 2. 01. Feldman M, et al. Maldigestion and malabsorption.
