Causes, Risk Factors, And Complications Of Giardiasis

Failure To Thrive

The chronic diarrhea that may occur with giardiasis could lead to malnutrition in children, and this might make it difficult for a child to maintain a healthy weight and normal growth development. Doctors refer to this as failure to thrive. Infants and children with failure to thrive might not reach developmental milestones such as sitting and walking at the expected ages. To diagnose failure to thrive, doctors obtain height and weight measurements for the patient over the course of at least six months to one year. In the case of possible parasitic infections like giardiasis, doctors may want to do blood tests to check for these conditions. To help in the diagnosis, parents who believe their child's condition might be caused by a parasite should mention any international travel, contact with untreated or unsafe drinking water, and visits to pools or water parks. If medical staff determine the patient is exhibiting failure to thrive, they will work with parents to improve the child's caloric intake and address other possible feeding issues.

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.
