Worm infections can cause a wide range of symptoms depending on the type of parasite and severity of infection. Common signs include abdominal pain, diarrhea, nausea, vomiting, bloating, and unexplained weight loss. Some people experience itching around the anus, fatigue, anemia, or nutrient deficiencies. In children, worm infections may lead to poor growth, irritability, and difficulty concentrating. Skin rashes, coughing, or breathing issues can occur when larvae migrate through the body. Early diagnosis and treatment are important, and medications are widely available through trusted pharmaceutical channels, including nizonide wholesale suppliers for clinical and pharmacy needs.
