Signs And Symptoms Of Lactose Intolerance Causing Bloating

Signs And Symptoms Of Lactose Intolerance Causing Bloating

Lactose intolerance happens when your body can't break down lactose properly.  Not enough lactase causes bloating, gas, and diarrhea after dairy. Many people often ask, 'Can milk cause gas?' 

This is a key concern for those experiencing symptoms of lactose intolerance, as the undigested lactose moves into the colon where it is fermented by bacteria, leading to the production of gas and other byproducts.

This article explores the connection between lactose intolerance and bloating, provides a detailed look at the digestion process of lactose, and offers strategies for managing and minimizing the discomfort associated with this condition

Understanding lactose intolerance

When lactose from milk is not digested due to a lack of lactase, it can cause gas and bloating. Understanding this connection is crucial for those asking, 'Can milk cause gas?

Managing lactose intolerance involves identifying lactose-containing foods, reducing dairy intake, and possibly using lactose-digesting supplements.  Are you overwhelmed with bloating caused by lactose intolerance? Considering the Bye Bye Bloat from The Good Bug will be beneficial in supporting your gut health during this process.

The basics of lactose intolerance and related bloating

When consuming milk or dairy products, the enzyme lactase in the small intestine is typically responsible for breaking down milk sugar for absorption. However, in those with lactose intolerance, insufficient lactase production means that lactose remains unprocessed and travels to the colon. 

There, it ferments with bacteria, leading to uncomfortable symptoms like gas, bloating, and diarrhea. These symptoms are not harmful and can generally be managed through dietary changes.

  • Lactose and digestion:
  • Lactose is a disaccharide, made up of two smaller sugars, glucose and galactose.

    The enzyme lactase, produced in the small intestine, is crucial for breaking down lactose into these monosaccharides, which are then absorbed into the bloodstream.

  • Insufficient lactase production:
  • In people with lactose intolerance, the small intestine doesn't produce enough lactase.

    This deficiency means lactose remains undigested as it moves into the large intestine, or colon.

  • Fermentation in the colon:
  • In the colon, undigested lactose is fermented by bacteria.

    This fermentation process causes the generation of gases such as hydrogen, carbon dioxide, and methane.

    In essence, bloating in lactose intolerance results from the fermentation of undigested lactose by gut bacteria, leading to gas accumulation and various gastrointestinal discomforts.

    4 types of lactose intolerance

    lactose tolerance


    Lactose intolerance develops when the body produces insufficient lactase, the enzyme required to break down lactose, the sugar in milk. This condition can impact both children and adults, and it frequently has a familial pattern, indicating a genetic factor. Here are some typical causes:

    1. Primary lactose intolerance: This is the most typical form and occurs as lactase production declines naturally with age. It tends to start manifesting in the teenage or adult years.
    2. Secondary lactose intolerance: This form develops when the small intestine reduces lactase production due to an injury, disease, or infection that affects the intestine.
    3. Developmental lactose intolerance: Premature babies may temporarily lack sufficient lactase, but this usually resolves as their digestive system matures.
    4. Congenital lactose intolerance:  Some babies inherit a gene causing permanent lactose intolerance.

    These causes contribute to the inability to digest lactose properly, leading to various digestive symptoms when consuming dairy products.

    Risk factors for lactose intolerance

    The majority of adults worldwide (about 65%) lose the ability to produce enough lactase after infancy.

  • Age: Lactase production tends to decrease as you age.
  • Ethnicity: Higher risks are seen in individuals of African, Asian, Hispanic, or Native American descent.
  • Premature birth: Prematurely born babies may have less developed digestive systems.
  • Intestinal conditions: Conditions affecting the small intestine, such as Crohn's disease, celiac disease, or bacterial overgrowth, can contribute.
  • Cancer treatments: Treatments like radiation and chemotherapy can also affect lactase production in the gut.
  • Foods high in lactose

    Foods containing high levels of lactose include:
