B65-B83: Helminthiases

B81: Other intestinal helminthiases, not elsewhere classified

Other intestinal helminthiases, not elsewhere classified, is a group of conditions that involves infestation of the intestines by various types of parasitic worms (helminths) that are not classified under any other specific category. The infestation can occur in several ways, but it's commonly through ingestion of contaminated food or water, contact with contaminated soil, or through a vector like a mosquito. Common symptoms of these conditions include stomach or abdominal pains, nausea, weight loss, and in severe cases, malnutrition due to absorption issues caused by these parasites. Over time, if not treated, these conditions can lead to complications, impacting not just the digestive system but other bodily functions as well. Such conditions predominantly occur in regions with poor sanitation or hygiene practices.
