Many times people are confused between the two. This is because the symptoms are very similar to each other, however Lactose Intolerance and IBS are completely different.

Today I will clarify the difference between the two, as well determine which from the two you are suffering from, if not both.

WHAT IS LACTOSE INTOLERANCE?cure-for-lactose-intolerance-step2

Lactose intolerance is a common digestive problem where the body is unable to digest lactose, a type of sugar mainly found in milk and dairy products. Symptoms of lactose intolerance include: flatulence (wind), diarrhea, constipation, stomach cramps and nausea.


A widespread condition involving recurrent abdominal pain and diarrhea or constipation, often associated with stress, depression, anxiety, or previous intestinal infection.


  • Lactose Intolerance

Well one can do a simple test. If you think you are lactose intolerant, begin with a dairy-free test. Avoid milk and other dairy products for a period of five days. If the symptoms of abdominal pain, constipation and diarrhea disappear completely, then you are most likely lactose intolerant. A Hydrogen Breathe Test is a definite way to determine if you are lactose intolerant or not. A Hydrogen Breathe Test looks for a higher than normal amount of hydrogen in the breath, caused by extra gases produced by bacteria fermenting the undigested lactose in the stomach. This simple diagnosis can be determined only by visiting your local doctor.treatment-for-lactose-intolerance

  • IBS

If the symptoms of abdominal pain, constipation and diarrhea do not stop after doing the dairy test, then you are not lactose intolerant. There is a high chance that you may suffer from IBS. An IBS test is not as straight forward as the lactose intolerance test. IBS tests include: Medical history and physical exam, a blood test for celiac disease, complete blood count (CBC), Sedimentation rate- a check for inflammation in the body and a stool analysis. Please  visit your local doctor for advise about these tests.

NB: It is possible to suffer from IBS and Lactose Intolerance. For further advice, contact your local doctor.

    I don’t know anyone with irritable bowel syndrome, but personally I am asian and it’s easy for us to be a little bit intolerant to lactose. It’s not like we get major allergic reactions or anything, we just get diarrhea when we drink milk on an empty stomach. Good information though. Thank you.

      Hi Win,

      Maybe Asians are not very stressed out people, hence do not suffer from IBS. Am glad you find the post informative. Hope you now know how to deal with the diarrhea caused by drinking milk.

      Kind Regards,

    I have always wondered what exactly lactose intolerance was. I don’t think I have that but. i have a strong dislike for milk. I cant remember the last time I drank milk. I can barely tolerate having it on my breakfast cereal.

      Hi Vic

      Thank you for your input. There many alternatives to milk such as soy, almond and coconut milk – if they are to your likings.
      Am glad you do know what lactose intolerance is.
