Pre Test Information:
No specific preconditions required
Lactose (Milk) intolerance is the inability to break down a type of natural sugar called lactose. Lactose is commonly found in dairy products, such as milk and yogurt. A person becomes lactose intolerant when his or her small intestine stops making enough of the enzyme lactase to digest and break down the lactose. When this happens, the undigested lactose moves into the large intestine. The bacteria that are normally present in the large intestine interact with the undigested lactose and cause symptoms such as bloating, gas, and diarrhea. The condition may also be called lactase deficiency.
Lactose intolerance usually causes gastrointestinal symptoms, such as gas, bloating, and diarrhea, about 30 minutes to two hours after ingesting milk or other dairy products containing lactose. People who are lactose intolerant may need to avoid eating these products or take medicines containing the lactase enzyme before doing so.
The signs and symptoms of lactose intolerance usually begin 30 minutes to two hours after eating or drinking foods that contain lactose. Common signs and symptoms include:
For milk allergy, you will be asked detail question about signs and symptoms, they ask you to keep a detail diary of food and to eliminate milk and again add back in diet to see the reaction.
Doctor generally recommend two test, a skin test and blood test. However blood test is more accurate than skin test. In skin test, your skin is pricked and exposed to small amounts of the proteins found in milk. If you're allergic, you develop a raised bump (hive) at the test location on your skin. While a blood test can measure your immune system's response to milk by measuring the amount of immunoglobulin E (IgE) antibodies in your blood.
A person can find that he/she has problem with milk or milk product if the symptoms are there within 30 minutes of milk consumption. Symptoms are abdominal bloating, pain or cramps, diarrhea, flatulence or gas, nausea which may accompanied by vomiting. Accurate diagnosis of lactose intolerance is through lab test suggested by doctors. .
Lactose intolerance is the inability to digest and absorb lactose, the natural sugar found in milk and milk products. All pure milk products like milk, yogurt, cream, butter, ice cream and cheese should be avoided depending on severity of the condition. Other food products in which milk is also used as an ingredient should also be avoided. For example breads and baked goods, pancake mixes, ready-to-eat breakfast cereals, instant soups, candy, cookies, salad dressings, deli meats etc.
Theoretically a person can become lactose intolerant at any stage of life. But it is commonly diagnose in early stage of life in teenage or in early adult hood. Lactose intolerance is caused by a deficiency in the enzyme lactase in the inner lining of the GI wall, which can develop at any stage of life. For this you should start tracking the food you consume and check what exactly cause the problem.
