Worms are parasites that invade the intestinal tract and other parts of the body. They are highly contagious.

Symptoms and Types
Worm symptoms vary according to type. In general, worms may be associated with overall fatigue, flu-like symptoms, and vitamin and mineral deficiencies. Often there are intestinal symptoms, digestive symptoms such as gas and burping, fatigue, joint pains, lowered resistance, and even mood changes and depression.

Pinworms are characterized by itching around the anus, but sometimes there are no symptoms at all. Other symptoms can include abdominal pain, joint pain, insomnia, convulsions, and many other widely varying signs.

The whipworm can cause mild to severe abdominal pain and diarrhea, along with weight loss, anemia, appendicitis, and rectal prolapse in women and children.

Tapeworms can cause mild to severe abdominal symptoms, such as cramping, and abdominal obstruction. Other symptoms can include fever, coughing, wheezing, and, if the worms enter the lungs, there may also be severe lung problems. Adult tapeworms can also create problems in the appendix, liver, gallbladder, or pancreas.

Hookworms usually do not present symptoms. When they do, the most common symptoms are a rash at the site where they invaded the body, pulmonary problems, severe stomach pains, and/or anemia.

Worm infection can occur as a result of digestive enzyme deficiencies, nutrient deficiencies, poor hygiene, improper elimination of human waste, walking barefoot on contaminated soil, and eating improperly cooked meat.
