Parasitic worm infections can cause a range of symptoms depending on the type of worm and the level of infestation. Common signs include abdominal pain, diarrhea, nausea, fatigue, and unexplained weight loss. Some people may experience itching around the anus, especially at night, or visible worms in stool. In severe cases, anemia and malnutrition can occur due to nutrient loss. Persistent cough or breathing problems may appear if the worms migrate to the lungs. It’s important to seek medical advice for proper diagnosis and treatment.
