lactose intolerance: Inability to fully digest and absorb lactose due to limited or no lactase activity in the small intestine. Congenital intolerance is inherited following an autosomal recessive pattern but is rare. It is more often due to a gradual decline of lactase production in adulthood following the ingestion of fewer lactose-containing foods or secondary to an intestinal mucosal brush-border injury. Prevalence is highest among Asians, Native Americans and Africans. Clinical signs include abdominal cramping, bloating, flatulence and diarrhea following the dietary intake of lactose.

CodeWAS
↥CodeWAS is a tool for exploring the associations between an endpoint and all of the medical codes and drug codes.
This is a new tool, please reach out using the contact form for feedback and improvement ideas.
First, a cohort is built by matching controls to the endpoint cases using year of birth and sex. Then, a Fisher test is done for all the medical codes and drug codes between the cases and controls of this cohort. Codes are reported in the table below if they have −log10(p-value) ≥ 6.
