What are the common symptoms of parasites in humans?

The presence of parasites in humans causes numerous health problems, some of which are life-threatening if left untreated. Parasites usually enter the body through food or water that is ingested. When found in the digestive tract, symptoms of parasites in humans can include fatigue, irregular or excessive bowel movements, weight loss, nausea, and cramps. Other types of parasites can reside in the blood and skin and cause itching, muscle and joint pain, or anemia. These symptoms have many other possible causes, so parasites can be difficult to detect without an x-ray exam.

Larger parasites, such as roundworms and tapeworms, attach to the intestinal wall and extract nutrients that would otherwise travel through the body. In severe cases, this leads to general malnutrition and weight loss. In the large intestine, the largest worms can clog the inside of the intestine and prevent regular bowel movements. They also cause cramps and gas. Eating improperly cooked meat increases the chance of worm infection.

The symptoms of parasites in humans can also be confused with the flu. Blood parasites cause flu-like symptoms at first: fever, chills, vomiting, and diarrhea. Severe infection causes digestive problems and difficulty swallowing, as well as anemia. Bloodworms are usually spread when an infected insect, such as a mosquito, bites a human and leaves feces inside the bite. Severe inflammation, swelling, or pain around the bite area indicates a possible parasitic infection.

Fungal parasites depend on moisture to thrive. They can live and breed best in areas that are exposed to a lot of sweat or other moisture; The armpits, groin, feet, and inner thighs are the main problem areas. Constant itching, dry and flaky skin, or peeling off of dead skin are also symptoms of parasites in humans. Ringworm, another common fungal parasite, causes a circular skin rash in the area of ​​infection.

Taking preventative measures can stop parasite symptoms in humans and stop parasite infection altogether. Avoiding parasites requires observance of sanitary food preparation, and having pets dewormed regularly can also prevent worms. The use of insect repellant and covering the skin eliminates a method of access for blood parasites through mosquitoes. Removing excess moisture from the skin stops the growth of fungus such as athlete's foot. Anyone who believes they have a parasitic infection based on known symptoms should see a doctor as soon as possible for a full examination, because an untreated parasitic infection could be fatal.
