Digestive system Malfunctions

Lactose WhatintolerancePhysical Affects:

Lactose intolerance occurs when the small intestine doesn’t produce enough of the lactose (sugar) digesting enzyme, lactase, which results in an inability for this sugar to be broken down into glucose and galactose. Usually these sugars are absorbed by the microvilli that makes up the intestinal lining into the bloodstream, however in a person who is lactose intolerant, food containing lactose moves straight to the large intestine instead. Here in the colon, bacteria found here ferments the lactose, producing hydrogen, methane, and carbon dioxide gas. Hydrogen produced acidifies the small intestine, causing an increase in osmatic pressure which leads to diarrhoea and other symptoms.

Lactose intolerance:

There are 3 types of lactose intolerance caused by different underlying factors.

Primary Lactose Intolerance: People who develop primary lactose intolerance, the most common type, produce enough lactase enzymes at birth however once they begin to eat solid foods, lactase levels drop and continue to drop naturally although there is still meant to be enough to account for an adult diet. In primary lactose intolerance, lactase production reduces sharply by adulthood, making the digestion of dairy difficult.

Primary Lactose Intolerance: This from of lactose intolerance is caused by the small intestine decreasing lactase production after an illness, injury, or surgery. Diseases often include an intestinal infection, celiac disease, bacterial overgrowth, and crohn’s disease. Treatment usually involves cutting out dairy for around 8 weeks depending on issue.

Congenital or developmental lactose intolerance: It is rare but sometimes

Treatment/manag ement: There is no treatment for lactose intolerance however it can be managed through limited consumption of dairy, choosing lactose-reduced foods and over the
