Causes, Risk Factors, And Complications Of Giardiasis

Lactose Intolerance

Lactose intolerance is a common complication of giardiasis, and it may persist even after the parasitic infection has been successfully treated. Lactose intolerance is an inability to digest lactose, a type of sugar found in dairy products. Patients with this intolerance typically experience bloating, stomach cramps, and diarrhea after consuming lactose-containing products, and nausea and vomiting may occur for some patients. To diagnose lactose intolerance, patients can have a hydrogen breath test. If the test is positive, patients may still be able to eat small amounts of dairy products, or they may prefer to transition to a lactose-free diet if their symptoms are severe. Almond milk, rice milk, coconut milk, and oat milk are all suitable non-dairy substitutes. Lactase enzyme supplements, which help break down lactose, could provide relief for some individuals. These supplements are available in liquid and powder forms, and patients add them to products with lactose shortly before consumption. Patients with lactose intolerance should always consult their doctor if they experience new or worsening symptoms.
