The worms consuming qi and blood described in Donguibogam can be closely linked to parasitic infection in modern medicine. In particular, symptoms such as anemia, chronic fatigue, and abdominal pain can be classic signs of a parasitic infection stealing iron and nutrients from the body.
A prime example is intestinal parasite infection. There are diverse types, including roundworm, whipworm, hookworm, and Taenia solium, which primarily enter the body through contaminated food or water and settle in the intestines. Certain parasites, notably hookworm and Taenia solium, firmly attach to the intestinal barrier to feed directly on blood and take nutrients. This creates a state akin to countless tiny straws continuously drawing blood. Consequently, iron in the body gradually depletes, eventually leading to iron deficiency anemia.
Iron is a core component of hemoglobin, which carries oxygen throughout our body. When iron is deficient, hemoglobin production drops, preventing the blood from delivering sufficient oxygen to tissues and organs. Reduced oxygen delivery to the brain causes dizziness, impaired concentration, and memory impairment; insufficient oxygen to muscles and organs leads to severe fatigue, lethargy, and reduced exercise capacity. In severe cases, the heart works excessively to pump more blood, causing palpitations and shortness of breath. A pale face and lips also result from poor circulation and a lack of hemoglobin.
Furthermore, parasitic infection directly affects gut health. It damages the intestinal barrier and triggers inflammatory responses, leading to chronic abdominal pain, diarrhea, and constipation. It impairs nutrient absorption, potentially causing malnutrition regardless of food intake. As the immune system becomes excessively active fighting off parasites, generalized fatigue and poor physical condition frequently occur. In rare instances, parasites can migrate to the bile duct or other organs, causing more severe complications.
While parasitic infections are often thought to be rare in modern society, risks still remain due to international travel, increased intake of organic produce, and consumption of raw foods such as raw beef or raw fish. Therefore, if unexplained chronic fatigue, anemia, or abdominal pain persists, it is vital not to dismiss them merely as stress or overwork, but to consult a medical professional for accurate diagnosis and treatment. Maintaining a healthy body requires paying attention even to the tiny guests hidden within us.
