Worm infections can cause a wide range of symptoms depending on the type and severity of infestation. Common signs include abdominal pain, diarrhea, nausea, vomiting, bloating, and unexplained weight loss. Some individuals experience fatigue, anemia, itching around the anus, or visible worms in stool. In children, worm infections may lead to poor growth, irritability, and difficulty concentrating. Chronic infections can weaken immunity and worsen nutritional deficiencies. Early diagnosis and treatment are important to prevent complications and transmission.
