Children are more infested with these worms than adults. There are several types of intestinal worms. The most common of these are roundworms, pinworms, threadworms, hookworms, tapeworms and giardia.
Roundworms may give rise to inflammation of the intestine and lungs, nausea, vomiting, loss of weight, fever, nervousness and irritability. Pinworms and thread worms may bring on intense itching in the area around the rectum.
Threadworms may cause periodic bouts of diarrhea alternating with constipation, loss of weight, cough and fever. Hookworms may give rise to anemia and nutritional disorders. The presence of giardia may result in pain in the calves and weakness in the legs.
Hookworms enter the human body through the skin from infected water. The tapeworms are transmitted into the body through undercooked flesh foods or foods contaminated by dogs.
The real cause of intestinal worms is wrong feeding. The eggs of these worms, taken into the human body through food and water can breed in the intestines only if they find there are a suitable medium for their propagation. This medium is an intestinal tract clogged with morbid mater and systemic refuse due to wrong feeding habits.
