Patients with lactose intolerance have high lactase activity
at birth, which deteriorations to low levels by adulthood. A lactose-intolerant
patient is likely to experience bloating, flatulence, and abdominal pain after drinking
milk products. This response happens due to the lack or deficiency of the
enzyme lactase, which is obligatory for the absorption of the carbohydrate
lactose. Pyrosis, or heartburn, is a burning sensation in the esophagus and
stomach due to the reflux of gastric acid. It is not produced by lactose intolerance.
Common reasons of constipation contain decreased physical activity, a low-fiber
regimen, insufficient consumption of water, and certain medicines. Lactose
intolerance is not the source of constipation.
