Intestinal worm infections can remain silent, allowing people to feel completely healthy while parasites live in the intestines. Symptoms may be absent with a low parasite burden, while heavier infections can cause abdominal discomfort, diarrhoea, appetite changes or nutritional deficiencies. Hookworm infections can be particularly concerning because they may cause iron-deficiency anaemia, fatigue and reduced physical capacity. Subtle clues such as unexplained anaemia, increased eosinophils or persistent digestive problems may warrant further evaluation, especially after exposure to contaminated food, water or soil. Diagnosis commonly involves stool testing, and repeated samples may improve detection because parasite shedding can be intermittent. Rather than self-medicating, persistent symptoms should be discussed with a healthcare professional.
