Worm infections can cause a wide range of symptoms depending on the parasite type and infection severity. Common signs include abdominal pain, diarrhea, nausea, bloating, gas, and unexplained weight loss. Some people experience itching around the anus, especially at night, fatigue, anemia, or vitamin deficiencies. Children may show irritability, poor growth, or difficulty concentrating. In heavier infections, cough, fever, bowel obstruction, or visible worms in stool may occur. Early diagnosis and proper treatment are essential. When sourcing treatment, working with a reliable mebendazole supplier ensures access to quality medication and appropriate guidance for effective parasite control and improved patient outcomes.
