Milk Allergy Symptoms In Adults

Surprisingly many allergies of milk and dairy products. Symptoms and remedies

Milk allergy is a relatively large number among children’s food allergies, second only to egg allergy. 2.5% of children experience up to 1 year old, but it is said that 85 to 90% of them will heal up naturally by the age of 3 years. Also, in adults it is not so much, it is said to be seen at a rate of about 0.1 to 0.5%. However, caution milk allergy is prone to severe allergic symptoms such as anaphylactic shock, so caution is necessary.

Cause of milk allergy

Milk allergy is caused by various kinds of proteins contained in milk. Several kinds of proteins are involved in milk allergy, the main cause of which is a protein called “casein”.

Since this casein has the characteristic of being resistant to heat, the structure of the protein does not change even when heated, and even if it cooks it does not change the force which causes allergy. Therefore, if you are allergic to milk, you should also carefully avoid milk contained in cooking. Also, even if the milk is fermented, the ingredients of casein remain. Therefore, even if it is fermented like cheese or yoghurt, people with milk allergy must avoid them carefully.

Symptoms of milk allergy

Symptoms of cow’s milk allergy may appear in a matter of minutes after ingestion (immediate reaction), after several hours, or after several days (delayed response). Even when any reaction is observed, it is important to note that even if only a very small amount is ingested, it may cause a violent reaction.

The following symptoms are mainly observed in milk allergy.

  • Skin: Skin redness, itching, hives
  • Mouth, throat: Lips, tongue, mouth, throat discomfort and itching / swelling, stomatitis, voice withering
  • Digestive organ: Abdominal pain, diarrhea, nausea, vomiting, bloody stools
  • eye: Eye congestion, itching, tears, eyelid swelling
  • Respiratory organ: Runny nose, sneezing, stuffy nose, cough, wheezing (say sauce), dyspnea
  • Whole body (anaphylaxis): The symptoms above occur simultaneously and sometimes shock state (sudden drop in blood pressure, tachycardia, consciousness disturbance, incontinence)

Method for testing milk allergy

When suspected milk allergy, we will judge the presence or absence of allergy by blood test or skin examination or complete removal examination.

Blood test

Collect blood and check ingredients. Whether there is an antibody against a protein causing milk allergy, it is judged whether there is milk allergy.

Skin test

Apply a small scratch on a part of the skin, apply allergen extract of milk allergy and observe the change. Or patch patch impregnated with allergen extract is stuck on a soft part such as the inside of the arm and change is observed. In either case, if redness appears on the skin, we determine that there is milk allergy.

Complete removal inspection

Food containing either milk or dairy product is completely removed for 2 weeks. In the case of breastfeeding nutrition, mother also completely removes the food containing either milk or dairy product for 2 weeks. If symptoms and conditions (bad bad mood and bad crying) seen in the body are improved compared to before removal, we determine that there is milk allergy.

A lot different from Japanese “lactose intolerance” is a different thing

Among Japanese, there are not a few people with “lactose intolerance” such as having diarrhea when drinking milk. This is a reaction to milk, so it tends to be confused with milk allergy, but in reality it is a completely different thing.

Lactose intolerance is a symptom caused by lack of enzyme “lactase” which decomposes sugar called lactose (lactose) contained in milk. It is not an allergy that causes a specific reaction to milk, it is a reaction that occurs because milk can not be digested successfully, so it can not be thought of as the same thing.

Lactose intolerance is also called lactase deficiency. In addition to diarrhea, symptoms of gastrointestinal tract with frequent farts and stomach are seen. Also, when you ingest dairy products as well as milk, symptoms such as diarrhea and tightness of your stomach may be seen. It is a reaction that occurs during digestion, so symptoms frequently occur 30 minutes to 2 hours after eating instead of eating.

Emulsifier and soy milk are dairy products?

People with milk allergy must avoid not only milk but also those with “milk” such as dairy products and milk drinks. So, should emulsifier and soy milk be avoided by people with milk allergy?
“Emulsifier” “milk” is emulsified “milk”

When looking at seasonings such as dressing and mayonnaise and raw material notation of sweets, “emulsifier” is often described. This emulsifier is not related to milk or dairy products, as it refers to substances that are added to emulsify, that is to make a cloudy uniform material by mixing things that are difficult to mix in normal conditions. In general, substances derived from soybean or egg are often used as emulsifiers.

Meaning that soymilk’s “milk” resembles milk

Soy milk squeezed soybeans with boiling water. It is said that it became known as soy milk because its appearance is cloudy and its rich taste resembles milk. In other words, although this is also named “milk”, it has nothing to do with milk, so people with allergies to milk can drink safely.

Because the taste resembles milk, it is often used for dishes for people with milk allergy. You can use it for sweets such as pudding and ice cream, or you can drink instead of coffee instead of cafe au lait. People with milk allergy are ingredients that can be relieved with confidence, but as it is made of soybeans that are likely to have severe allergic symptoms as milk, as a matter of course, so as to avoid those who are allergic to soybean Please do it.

How to deal with milk allergy

The way to deal with milk allergy is as follows.

Avoid milk · dairy products

The most basic is that you do not ingest allergic reactions themselves. As Japanese diet has become westernized, milk and dairy products are hiding everywhere in everyday meals.

Besides generally well-known milk, cheese and yogurt, condensed milk, fresh cream, lactic acid bacteria drinks etc. cause allergies to milk. Cakes and puddings, chocolate confectionery, sweets such as ice cream and pasta of gratin and cream type are used in large quantities of dairy products, so it is necessary to be careful. In order to avoid it efficiently, pay particular attention to the following points.

1. Use alternative milk

Because milk protein is contained in commercially available powdered milk, infants who have allergies to milk may have allergic reactions. Let’s use milk substitute products such as “protein hydrolyzed milk” and “special milk” for allergic children.

2. Confirm raw material display well

Many processed foods use milk as a raw material. Also, not only foods and drinks, but also medicines may contain milk protein. Even when taking medicines, let’s check the raw material display firmly.

3. In case of breast milk, also note the mother’s meal

If mother ingests milk or dairy products, milk protein may migrate to breast milk. Mothers should consciously avoid milk and dairy products during the period of breast feeding to babies with allergies to milk. It is also good to stop mother’s milk feeding and use milk powder exclusively for milk allergy babies if mothers are concerned about removing dairy products from their diet.

■ Hyposensitization therapy

In order to prevent anaphylactic shock, which is a heavy allergic reaction, there is also “desensitization therapy” which takes milk little by little under the supervision of a doctor and habituates it to the body. However, if you try to get your body to milk based on your own standards, symptoms may become serious. Be sure to consult a doctor and do not take milk or dairy products at your own discretion.


Milk allergy often has a response as soon as ingestion, but there is also a characteristic that delayed type, which occurs slowly, also occurs. Therefore, it is not easy to understand that allergies are caused by milk and dairy products.

Also, it is known that about 90% of milk allergy develops within 3 months of age. Infants can not speak, so if constipation, diarrhea, bad mood, crying at night, etc. continue, it may be better to doubt cow’s milk allergy. If you continue breastfeeding mothers taking milk allergy but milk powder nutrition or dairy products, the symptoms may become even more severe. If you think that it is “strange” even a little, let’s consult a medical institution such as pediatric department.
