A food allergy causes an immune system reaction that can cause serious symptoms throughout your body, such as throat swelling. Food intolerances are caused by an inability to break down a particular food and usually only cause symptoms that affect your digestive system. Normally, your small intestines produce an enzyme called lactase to break apart lactose molecules.
Although cow’s milk protein sensitivity and lactose intolerance are not the same thing, they can sometimes occur at the same types of arthritis time, since food allergy can cause secondary lactose intolerance. If your baby is sensitive to dairy products it is highly unlikely that the problem is lactose intolerance, although many people may tell you so.
If you have lactose intolerance, your body doesn’t produce enough of this enzyme to effectively break down the milk sugar when you consume dairy. If you reintroduce dairy into your diet and baby reacts, cut out dairy products again for at least another month.
If baby’s allergy to cow’s milk protein via breastmilk is severe, it’s best to wait at least 6 months before trying to reintroduce dairy. For allergic babies, avoiding the allergen makes it less likely that baby will develop a lifelong or life threatening allergy. If your baby is sensitive to dairy in your diet, it will not help to switch to lactose-free dairy products. Cooking dairy products may reduce but will not eliminate the allergens.
There are a number of lactose-free dairy products available to buy that are suitable for people with lactose intolerance. There are a number of alternative foods and drinks available in supermarkets to replace the milk and dairy products you need to avoid. It’s worth experimenting with different foods to find out if there are any dairy products you can eat, as they’re a good source of essential nutrients like calcium. Some people have lactose intolerance because they have a genetic difference that reduces the effectiveness of their body in being able to break down lactose. Your doctor can confirm a diagnosis of lactose intolerance with a clinical test.
