Parasitic worm infections can cause a wide range of symptoms depending on the type of worm and severity of infection. Common symptoms include abdominal pain, diarrhea, nausea, vomiting, bloating, and unexplained weight loss. Some individuals experience fatigue, anemia, vitamin deficiencies, or itching around the anus. In more advanced cases, cough, shortness of breath, muscle pain, or visible worms in stool may occur. Children may show delayed growth or poor appetite. Early diagnosis and proper treatment are essential to prevent complications. Many healthcare providers rely on trusted pharmaceutical sources, including a reliable nizonide wholesaler, to support effective antiparasitic treatment options.
