Dairy sensitivity vs. lactose intolerance
Potential dairy sensitivity symptoms
Is it a dairy sensitivity, milk intolerance, or something else?
Written on October 26, 2022
Do you sometimes experience symptoms like abdominal bloating or stomach discomfort—and suspect dairy products are at fault? Dairy sensitivity is different from cow’s milk allergy, a dairy allergy, or any other food allergy. Milk or products made from milk may trigger a dairy sensitivity in some people, which might lead to a number of unpleasant symptoms.
Here, you’ll learn more about the potential signs and symptoms of a dairy sensitivity. But before we get to that, let’s discuss how a dairy sensitivity is different from lactose intolerance.
Dairy sensitivity vs. lactose intolerance
A dairy sensitivity isn’t the same as lactose intolerance. Knowing how these two are different can help you better understand your body’s response to dairy products—so you can take steps to reduce the symptoms you may be experiencing.
| Condition | What Causes It | How the Body Responds | Common Symptoms | Common Trigger Foods |
|---|---|---|---|---|
| Lactose Intolerance | Deficiency of lactase, the enzyme needed to digest lactose | Difficulty digesting the sugar lactose found in dairy products | Digestive discomfort, bloating, gas, and diarrhea after consuming dairy | Cow’s milk, cheese, ice cream, butter, yogurt, and foods containing lactose |
| Dairy Sensitivity | Immune response to milk antigens (milk proteins) | The immune system reacts to proteins found in milk or milk products | Symptoms may resemble lactose intolerance symptoms, though reactions can vary | Cow’s milk, cheese, ice cream, butter, yogurt, and foods containing milk proteins |
These are some common dairy food products which may trigger either an intolerance or sensitivity:
- Cow’s milk
- Cheese
- Ice cream
- Butter
- Yogurt
Certain foods like sauces, gravies, cookies, quiche, soups, breakfast cereal, and custards might also contain lactose. Milk and dairy products can also appear on food labels as whey, whey protein, milk casein, milk sugar, buttermilk, sour cream, milk byproducts, and more.
Potential dairy sensitivity symptoms
Stomach bloating
If you often feel bloated to the point of discomfort or experience excessive abdominal bloating or swelling, a food you regularly eat could be at fault. Dairy products—such as milk, cheese, and yogurt—are candidate foods to consider when trying to determine what foods cause bloating, since this is one possible dairy sensitivity symptom.
Stomach pain
Stomach pain and discomfort, including abdominal pain and cramping, may also be brought on by dairy sensitivity.
Headaches and migraines
Dairy could be a headache trigger. Headache and migraine frequency may also be connected to dairy products if you have a dairy sensitivity.
Is it a dairy sensitivity, milk intolerance, or something else?
Maybe you frequently experience one or more of the symptoms mentioned above. If that’s the case, how can you tell if the cause is a dairy sensitivity, milk intolerance, or some other food in your diet (like gluten)?
Try an elimination diet
Undergoing a two-part elimination diet is one of the best ways to see if your symptoms could be related to a specific kind of dairy product. Here’s how to do an elimination diet.
Take a food sensitivity test
What if your symptoms don’t seem to correspond with the presence or absence of dairy in your diet? Then it’s possible that some other food in your diet is contributing to your symptoms, and it’s worth considering an elimination diet to find the culprit (or culprits).
An elimination diet, however, can be a somewhat tedious and time-consuming process because it isn’t always easy to know what foods to temporarily eliminate first and then add back. Typically, you’d start by eliminating foods you suspect are behind your symptoms—but since most of us eat a varied diet made up of many different foods, your list of “suspect” foods could be pretty long. Where should you start in that case?
The Everlywell at-home Food Sensitivity Test may help guide your elimination diet and make it easier for you to determine if certain foods are at fault for your symptoms. This test tells you how your IgG antibodies react to 96 common foods. Foods that have a high IgG reactivity level are often targeted first in an elimination diet—an approach that’s commonly used to investigate symptoms potentially related to food.
