Worm infections, also called intestinal parasitic infections, can cause a range of symptoms depending on the type and severity. Common signs include abdominal pain, diarrhea, nausea, vomiting, and unexplained weight loss. Some people may experience itching around the anus, especially at night, fatigue, or visible worms in stool. In children, symptoms can include irritability and poor growth. In more severe cases, anemia or nutritional deficiencies may develop. Proper hygiene and timely treatment are important.
