Intestinal Worms Can Stay Hidden Despite Few or No Symptoms
Some people can have worms living in their intestines without feeling sick.
These worms usually do not live in the stomach, despite how people often describe the problem.
A small number of worms may cause no clear symptoms.
Larger or longer-lasting infections can cause stomach discomfort, diarrhoea, appetite changes or poor nutrition.
Hookworms can take blood from the intestine and may lead to anaemia and tiredness.
Blood tests can sometimes show clues, such as increased eosinophils.
A single stool test may miss an infection because worms do not always release eggs.
Doctors may therefore test several stool samples collected on different days.
People should seek medical advice instead of taking deworming medicine based only on assumptions.
Intestinal worms usually live in the intestines rather than the stomach.
Low parasite levels may cause no symptoms, allowing people to remain unaware of infection.
Possible warning signs include abdominal discomfort, diarrhoea, appetite changes, anaemia and fatigue.
Unexplained anaemia, eosinophilia and exposure to contaminated food, water or soil may warrant evaluation.
Doctors may recommend at least three stool samples on separate days because parasites are not shed consistently.
