3. Weight loss
is another symptom of giardia. People who lose weight when they have giardia may lose up to 15 pounds. It has been reported that only 66% of people with giardia have weight loss symptoms. Chronic diarrhea can cause weight loss as well. In children, if the symptoms last longer than a week, children can lose weight.
The reason for weight loss is because the person may not be able to eat any food. Every time food is ingested, a person just vomits. The more a person vomits and doesn’t eat, the more weight he or she will lose. It’s not good to vomit constantly because it could make abdominal pains even worse.
A medical professional would more than likely suggest foods that a person could eat until giardia clears up. It’s best to stay home from work or keep a child home from school until giardia is gone.
