If not managed properly, lactose intolerance may cause severe digestive problems. These symptoms may appear as quickly as 30–60 minutes after eating menu.
The most common symptoms are:
- bloating
- abdominal cramps
- gas
- diarrhea
- nausea
Some people also experience an urgent need to go to the toilet, vomiting, lower belly pain, and constipation. สมัคร UFABET
Diarrhea occurs due to undigested lactose in your small intestine, which causes water to move into your digestive tract.
Once it reaches your colon, the lactose is fermented by the bacteria in your gut. Forming short-chain fatty acids (SCFAs) and gas. This causes bloating, gas, and pain .
The severity of symptoms varies based on how much lactose you can tolerate and how much you’ve eaten.
Fortunately, these symptoms last only briefly. You’re also typically not affected unless you consume large amounts of lactose or have another condition. That’s worsened by the digestive irritation caused.

May cause digestive problems, including bloating, gas, abdominal cramps, and diarrhea.
Tests for lactose intolerance
Here are the ways that your doctor can test you for lactose intolerance :
- Hydrogen breath test. This test measures hydrogen in your breath after lactose intake. High amounts of hydrogen suggest digestive problems that may be related to lactose intolerance but also caused by other issues.
- Lactose tolerance test. This test measures your blood sugar after lactose ingestion. If you have lactose intolerance, your blood sugar levels won’t be affected because your body can’t break down lactose.
- Genetic test. This test checks for genetic causes, but people with secondary lactose intolerance may receive a false negative.
- Lactase activity at jejunal brush border. This invasive and expensive method requires a biopsy of the jejunal brush border, which is part of your small intestine, but is a definitive way to assess lactase activity.
- Stool acidity test. Often used for babies and infants, this test measures stool acid levels, which have a lower pH in cases.
