Too thin and too fat is due to the dysfunction of the spleen and stomach, which leads to the inability to distribute nutrients throughout the body, rather than ascaris in the stomach.

Whether there is ascaris can be checked by stool test. If there is a roundworm, it usually has the following manifestations:

A. Patients usually have symptoms such as loss of appetite, nausea, vomiting and intermittent periumbilical pain.

B. Urticaria, itchy skin, angioneurotic edema, conjunctivitis and other symptoms may occur.

C sudden colic in the right upper abdomen, radiating to the right shoulder, back and lower abdomen. The pain increases intermittently, accompanied by nausea and vomiting. If eggs are detected in the patient's feces, a diagnosis can be made. For those who can't find eggs in feces, but the clinical manifestations are suspected of ascariasis, anthelmintic therapy can be used for diagnosis and differentiation according to the worm morphology discharged by patients. Patients suspected to have allergic pneumonia caused by pulmonary ascariasis or ascaris larvae can be diagnosed by examining ascaris in sputum. Severe cases can cause malnutrition, mental and developmental disorders, and sometimes emotional anxiety, irritability, grinding teeth, itching and convulsions; Some patients may have allergic reactions, such as angioneurotic edema and intractable urticaria. Sometimes it can cause serious complications such as biliary ascariasis, ascaris intestinal obstruction, intestinal perforation and peritonitis.
