Chronic constipation
It is a much less common symptom of lactose intolerance. Constipation is characterised by the passage of hard stools, difficulty defecating, and a sensation of bowel exertion. Methane gas produced by microflora fermentation is a known constipation agent because it delays bowel emptying. Although not strictly related to lactose intolerance, this symptom has been reported.
Lactose intolerance and lactose malabsorption are commonly confounded. A proper diagnosis reveals that some individuals can adequately metabolise lactose, and that the issue is its intestinal absorption. The confusion is primarily caused by the fact that gastrointestinal symptoms are also classic indicators of other prevalent diseases, such as diabetes and bacterial infection, etc. In addition, they are frequently influenced by diet, and a number of other dietary components may cause reactions that are incorrectly attributed to lactose intolerance. As a result, it is essential to obtain a thorough laboratory diagnosis, as his clinical picture is quite confusing. Some individuals can tolerate a small amount of lactose content without developing severe symptoms, whereas others are lactose intolerant to a severe degree and develop severe signs of discomfort, upset stomach, and abdominal pain.
