Today we are going to talk about something that worries many parents. That is the allergy that occurs when young children drink milk, or as we say in English, `` Milk Allergy ''. Sometimes you may have seen things like your baby getting sick after drinking milk, having difficulty breathing, etc. So let's see what this really is, why it happens, and what we should do. Don't worry, knowing these things properly can reduce many problems.
What exactly is a milk allergy?
Simply put, a milk allergy is when our immune system , the system that protects us from disease, overreacts to certain proteins in milk. Think of it like an army in our bodies, which we call the immune system . Its main job is to protect us from disease by fighting germs and viruses that enter our bodies.
However, when a person with a milk allergy ingests milk proteins, the immune system mistakenly thinks that these milk proteins are a dangerous, harmful invader. So, it starts to fight against that 'invader'. That's when an allergic reaction occurs. It's like our own defenses attacking the wrong person.
Milk is one of the most common food allergies among young children. But there is good news. Most children outgrow this milk allergy as they grow older. So there is hope.
What happens during an allergy? What are the symptoms?
When someone with a milk allergy eats or drinks milk or something containing milk, their body reacts to one or more of the proteins in milk. This is mainly caused by two types of proteins in milk. These are called casein and whey. Some people are allergic to casein only, while others are allergic to whey only. Others may be allergic to both.
So, when these proteins enter the body, the body releases chemicals like histamine. These chemicals are what cause each symptom. These symptoms can vary from person to person. Also, the symptoms that occur at each time can vary even for the same person. Some reactions are very mild, while others are a little more severe.
These are the symptoms that are often seen:
- Wheezing (a whistling sound coming from the chest)
- Difficulty breathing
- Cough
- Hoarseness of voice
- Feeling like your throat is constricted
- Stomach ache , stomach pain
- Vomiting
- Bloating ( diarrhea )
- Itchy eyes, watery eyes, swollen eyes
- Hives
- Body swelling
- Sudden drop in blood pressure, fainting, and loss of consciousness.
The most important thing: Sometimes, even someone who has had a mild reaction before can have a very severe reaction the next time. So you always have to be careful.
Anaphylaxis – the most dangerous condition
The most severe and dangerous reaction to milk allergy is called `anaphylaxis`. This is not something to be trifled with. `anaphylaxis` is a very rapid, life-threatening allergic reaction.
This may start with the same mild symptoms as mentioned earlier. But the condition can quickly get worse. You may not be able to breathe, lose consciousness, or affect more than one part of the body. Anaphylaxis can be fatal if not treated quickly. So you need to be very careful about this.
Isn't this lactose intolerance?
Many people confuse this milk allergy with a condition called lactose intolerance, because symptoms such as stomach pain and bloating can occur in both.
But these two are two completely different situations.
- Milk allergy is an immune system problem that can cause life-threatening reactions such as anaphylaxis.
- Lactose intolerance is a condition in which the body lacks the enzyme needed to digest lactose, a sugar found in milk. This can cause stomach upset, bloating, and diarrhea. However, it is not a life-threatening condition.
Therefore, it is very important not to confuse the two. If you have any doubts about this, it is best to ask a doctor for clarification.
How do you know for sure if you have a milk allergy?
If you think your child has a milk allergy, see a doctor. He or she may refer you to an allergist/allergy specialist for further testing.
This specialist will ask you things like:
- How common is an allergic reaction?
- How long does it take for symptoms to appear after eating a food?
- Does anyone in the family have other conditions such as allergies, eczema, or asthma?
Then it is possible to do tests like this:
1. Skin Test: In this test, a small amount of milk protein solution is applied to a small area of skin on the child's arm or back. After about 15-20 minutes, the area is checked for redness, swelling, and a small blister-like rash. If so, it can be assumed that there may be a milk allergy. Before doing this test, you will be asked to stop taking certain medications (e.g. antihistamines) for about 5 to 7 days. These medications can affect the results of the test.
2. Blood Test: Sometimes a blood test may be done along with the skin test. A small sample of blood is taken and sent to a lab. There, the blood is checked for the presence of `IgE antibodies` that have been formed against milk. `IgE antibodies` are a special type of protein that is associated with allergies. If there are enough of these in the blood, there is a high chance that you have a milk allergy.
3. Oral Food Challenge: If the above two tests are inconclusive, a specialist may decide to do this test. This is done very carefully, under medical supervision. The child is given milk in gradually increasing amounts and is carefully observed for any symptoms. This is the best way to confirm whether or not there is a milk allergy.
What to do if you have an allergy? What are the treatments?
It is essential for a child with a milk allergy to always carry two epinephrine injections. This is a life-saving medication in case of a severe allergic reaction, called anaphylaxis.
Epinephrine is a prescription medicine that you need to get from a doctor. It comes in a small, portable device (auto-injector). It is very easy to use. Your doctor will show you how to use it.
Why two doses of epinephrine? The idea is to keep two in case one doesn't work or if a second dose is needed.
Your doctor may also give you an Allergy Action Plan . This will clearly outline how to prepare for, recognize, and treat an allergic reaction. Share this plan with other people who will be caring for your child (e.g., relatives, babysitters, school teachers, sports coaches). If you are abroad, have your child wear a medical alert bracelet .
Every second counts in an allergic reaction. If your child has severe allergic symptoms, such as difficulty breathing or a feeling of tightness in the throat, use epinephrine immediately. Also, if symptoms occur in two different parts of the body at the same time (for example, skin rash and vomiting), use epinephrine. Then call 911 (the emergency ambulance service) immediately and take your child to a hospital. Sometimes, even when the worst of the symptoms seem to have passed, a second wave of severe symptoms can occur.
What else do we need to know as parents?
It is best not to give a child with a milk allergy anything containing milk or milk proteins. This is the most important thing.
So be careful about these things too:
- Read food labels carefully: Read the label of every food and drink you buy from the store. Teach your child to read labels when they are a little older. Look for words like “milk,” “milk powder,” “casein,” “whey,” and “lactose.”
- Hidden Milk: Sometimes, milk can be found in foods we don't even think about. For example, cured meats like sausages and ham, salad dressings, baked goods, some chocolates, and crackers can also contain milk.
- Be careful with “non-dairy” labels: Some foods may still contain milk proteins, even though they are labeled “non-dairy.” So be sure to check the ingredients list on the label.
- Be careful about cross-contamination: This is a bit complicated. Imagine if you make a dairy and a non-dairy food on the same machine, using the same equipment, could some milk get into the non-dairy food? That's what's called cross-contamination.
- Some food packages have warnings such as “May contain milk,” “Processed in a facility that also processes milk,” or “Manufactured on equipment also used for milk.” Avoid giving foods with these labels to your child.
- However, not all companies are required by law to put such warnings on the label. So if you are unsure about a food, it is safest to contact the company that makes it or check their website to find out if the food may have come into contact with milk.
Although these things may seem a bit annoying, they are very important for your child's safety. After a while, these things will become a habit for you.
Final Take-Home Message
Milk allergy is not something to be afraid of, but it is something to be careful about.
- If you suspect your child has a milk allergy, see a doctor immediately.
