Glass of milk
Even though milk is not considered a trigger for acid reflux, the high fat content of cow milk might cause problems if you have reflux.

Milk is considered to be part of a balanced and healthy diet.

However, there are people who regularly experience chest pain after drinking milk or consuming other dairy products.

There are a number of conditions that could cause this chest discomfort, we list the most common ones below.

If you don’t know why milk causes you chest pain, it’s best to talk to your doctor to find out the root cause, as this will be a big help in correctly managing your condition.

What happens in your body when you drink milk?

Growing up, milk was always so hyped up. Adults always said, if you want strong bones, drink a glass of milk every day. But, what happens when you drink a glass of milk?

For starters, similar to other foods, milk stays in the stomach for a while waiting to be digested.

During this period, the enzymes in milk start to denature into proteins for easy absorption.

The result of this process is the production of gastric lipase whose size will depend on the fat content of the milk.

After the molecules are broken down, the enzymes go to the smaller intestine, and polypeptides and amino acids are absorbed.

If you are sensitive to milk, however, the process will be a bit different.

Because your body is unable to produce enough lactase, the enzymes from the milk won’t be fully broken down and will be passed to the lower digestive tract.

Of course, this isn’t where it’s supposed to be and that’s why you may experience stomach ache, diarrhea, or bloating.

Why does your chest or stomach hurt after drinking milk?

These are the most common reasons that could cause chest or tummy pain after drinking milk:

  • lactose intolerance, milk allergy
  • acid reflux
  • gallbladder problems

However, some other conditions can also make your chest hurt after milk.

For example, after drinking very cold or very hot milk, you might have a so-called esophageal spasm, which is the painful contraction of the esophagus. It will cause chest pain right after drinking.

Milk and lactose intolerance, milk allergy

There are a number of different names for seemingly the same condition: milk causes you chest or belly troubles.

While the symptoms might look similar, the underlying causes are different:

  • Milk allergy: It is an abnormal response of the immune system to the proteins in the milk.
  • Lactose intolerance: It is an abnormal response of the digestive system to the sugars (lactose) in the milk.

Stomach cramps, bloating, diarrhea, vomiting can be a symptom of both.

You can consume lactose-free products if you have lactose intolerance. However, you need to stay away from all dairy products if you have a milk allergy.

Milk allergy can have more severe symptoms, e.g. anaphylaxis, which require immediate medical attention.

Therefore it is important to find out whether you have a milk allergy or lactose intolerance. Consulting with an allergologist is recommended if milk or other dairy products are causing you stomach problems.

Does milk really trigger or remedy acid reflux?

Over the years, there has been no strong evidence linking milk as a trigger for acid reflux. However, high-fat foods have been known to digest slowly in the body and thus worsening acid reflux.

Also, certain ingredients that are often used with milk like chocolate or coffee ease the muscle between the esophagus and stomach. As a result, triggering acid reflux.

Low-fat or fat-free milk is somewhat easier to digest, because of the lower or no fat content. If you are prone to acid reflux but don’t have problems with lactose, such types of milk, or buttermilk might fit into your diet.

Acid reflux and lactose intolerance

As mentioned above, the medical community doesn’t consider dairy products as a cause of acid reflux.

If you are lactose intolerant, you may experience symptoms such as abdominal pain, bloating, and vomiting, which may seem a bit similar to those of acid reflux.

With that being said, you should also keep in mind that high-fat foods may worsen acid reflux.

The likes of full-fat cow milk should be avoided by people with lactose intolerance. A good alternative is a plant-based milk, such as the ones listed below.

Avoiding dairy products altogether isn’t such a good idea because you will be denying your body essential nutrients. You can try lactose-free products, maybe buttermilk is a heartburn-friendly alternative for you.

The bottom line is, despite milk not being considered an acid reflux trigger, if you experience side effects, you should avoid high-fat dairy products, and opt for alternatives that offer similar nutrients.

Gallbladder problems

The gallbladder helps in the process of digesting fat.

If you are drinking fatty milk and have issues with your gallbladder, like gallstones or infection, then the digestion process might become painful.

Besides stomach pain the common symptoms are:

  • vomiting
  • fever
  • brownish-colored urine
  • light-colored stool

If you are experiencing such symptoms, you need immediate medical help.

Full-fat cow milk vs goat milk vs plant-based milk

There are different types of milk, depending on the one you drink, the effects can vary. Let’s look at the three most common types of milk and their benefits.

Full fat cow milk

Cow

The calcium will ensure your bones are healthy, whereas the proteins will aid maintain lean muscle mass.

Goat milk

Goats, a baby and an adult

Unlike cow milk, goat milk contains less lactose. It is also more nutritionally dense.

With every cup of goat milk you take, you are downing 168 calories. This is a bit too high if you are on a low-calorie diet.

Nonetheless, it’s an excellent source of protein, carbs, calcium, vitamin D, and fat. Kindly note that the test of goat milk highly depends on the breed and processing.

Plant-based milk

Almonds and almond milk
Plant-based milks like almond milk can be a good alternative if you have either reflux or lactose intolerance.

These days plant-based milk is becoming more popular.

When you visit your favorite supermarket, you are likely to find a line-up of almond, soy, coconut, and cashew milk amongst others.

One of the reasons why you should consider plant-based milk is if you are lactose intolerant.

With these types of milk, you get nearly all the nutrients such as protein, calcium, and vitamins.

It’s imperative that you look at the nutrient content of plant-based milks before buying it. Because there are some which fall short regarding the availability of nutrients.

Final thoughts

If milk or other dairy products are causing you chest or stomach discomfort, you might do several things to manage your condition:

  • try low-fat or fat-free alternatives
  • switch to lactose-free alternatives
  • switch to plant-based alternatives and remove dairy products from your diet

If even lactose-free products are causing you symptoms, you should stop consuming everything that contains milk and see an allergologist, as you might have a milk allergy.

You also need to consider the possibility that it is not milk or dairy that is causing the symptoms, but some other ingredient. Fat, sugar, and caffeine are the most common triggers of gastric problems, maybe one of these is the reason for your chest pain and not dairy.
