Signs of Abnormal Stool
When lactose is not properly absorbed in the small intestine, it can lead to abnormal stool. This can cause the stool to become loose and runny. It is important to note that abnormal stool may not be immediately produced after consuming lactose. In some cases, it may take a day for the effects to be noticeable. This can sometimes lead to misdiagnosis, as it may be mistaken for diarrhea caused by an infection. For example, consuming dairy products at night could result in abnormal stool the following day.
Painful Bowel Movements: A Possible Consequence of Lactose Intolerance
Individuals who suffer from lactose intolerance may experience painful bowel movements. When this condition becomes frequent and forceful, it can lead to irritation and soreness in the anal cavity. In some rare cases, the irritation can escalate to a point where the stool contains traces of blood and mucus. This symptom is particularly prevalent in individuals with severe lactose intolerance who have consumed a significant amount of dairy, as well as in infants.
