Internal parasites, such as worms, are a common issue for both humans and animals. They are typically contracted by ingesting contaminated food or water, or through contact with an infected person or animal. In some cases, an individual may have an internal parasite without any symptoms. However, there are some common signs that may indicate the presence of an internal parasite.
The most common symptom of an internal parasite is digestive upset, such as abdominal pain, bloating, gas, nausea, and diarrhea. Other signs may include unexplained weight loss, fatigue, anemia, and skin rashes. In some cases, a person may experience fever, vomiting, coughing, or coughing up blood.
Individuals who suspect they may have an internal parasite should seek medical advice. A doctor may order a stool sample to check for the presence of parasites or eggs. Blood tests may also be ordered to look for signs of infection.
In some cases, a doctor may order an imaging test, such as an X-ray or CT scan, to detect parasites in the intestines or other organs. A doctor may also recommend a liver or spleen ultrasound to look for liver flukes.
To prevent the spread of internal parasites, individuals should practice good hygiene, such as washing hands after using the restroom and before handling food. People should also avoid drinking water from sources that may be contaminated, and should cook food thoroughly. In addition, individuals should wear protective footwear when walking in areas that may be contaminated with parasites.
