Why Does Milkshake Upset My Stomach? The Ultimate Guide.

Milkshake may normally upset your stomach due to the lactose content, which your body may find hard to digest. Milkshakes can be a great treat, especially on a hot day.

However, for some individuals, they can cause stomach upset, bloating, or fullness. This can be due to lactose intolerance, where the body does not produce enough lactase to break down lactose, the sugar found in milk. When lactose travels to the large intestine without being broken down properly, bacteria in your gut will ferment it leading to symptoms of discomfort.

Additionally, if the milk used to make the milkshake is spoiled or has not been stored correctly, bacteria growth may cause food poisoning leading to diarrhea and vomiting. In this article, we will explore various reasons why milkshakes upset your stomach and what you can do to avoid this.

Causes Of Stomach Upset After Drinking Milkshake

Have you ever experienced an upset stomach after drinking a milkshake? Well, you’re not alone. Milkshakes are a popular beverage worldwide, but they can cause stomach upset, especially when consumed in excess. We will discuss the different causes of stomach upset after drinking milkshakes.

Read on to learn more.

Lactose Intolerance – How This Is Connected To Milkshakes

Lactose intolerance is a widely known condition where an individual experiences gastrointestinal symptoms after consuming dairy products. When lactose, a sugar found in milk, is not digested correctly, it can cause gas, bloating, and diarrhea. Milkshakes, which contain milk as their primary ingredient, can cause stomach upset in people with lactose intolerance.

  • Milkshakes contain lactose, which some people can’t digest properly.
  • Lactose intolerance affects people differently with varying degrees of intolerance.

Dairy Allergy – And How It Affects People Who Consume Milkshakes

Dairy allergy is less common than lactose intolerance, occurring in only about 2. 5% of children and 1% of adults. People with dairy allergy have a hypersensitive reaction to proteins found in milk. Symptoms of dairy allergy can include digestive issues, hives, eczema, and anaphylaxis.

Those with dairy allergy should avoid milk-based drinks, including milkshakes.

  • Dairy allergy is an immune system reaction to milk proteins.
  • Symptoms of dairy allergy can be severe.

High Sugar Content – Why Milkshakes Can Cause Stomach Upset If Taken In Excess

Milkshakes are usually high in sugar content, which can cause stomach upset if consumed in excess. Overconsumption of sugar can lead to digestive symptoms such as bloating, gas, and diarrhea.

  • Milkshakes can contain high amounts of added sugar.
  • Excessive sugar intake can cause stomach upset.

Existence Of Thickeners And Additives In Milkshakes – And Their Possible Role In Stomach Upset

Milkshakes often contain additives and thickeners like xanthan gum, carrageenan, and corn syrup that could contribute to stomach upset. These additives can irritate the lining of the digestive tract, causing symptoms like nausea and stomach cramps.

  • Some milkshakes contain additives that can be hard for some people to tolerate.
  • Some additives found in milkshakes, such as carrageenan, have been linked to digestive problems.

Milkshakes can cause stomach upset due to lactose intolerance, dairy allergy, high sugar content, and additives and thickeners. If you experience stomach upset after consuming milkshakes, it may be best to limit your intake or avoid them altogether. Consider alternatives like non-dairy milk or lower sugar options to enjoy the taste of milkshakes without discomfort.
