The concept of 'worms' described in Donguibogam can often be explained in modern medicine as 'protozoan infection'. In particular, if symptoms such as chronic diarrhea, abdominal distension, gas, and weight loss persist after traveling abroad, protozoan infections such as Giardia lamblia, Cryptosporidium parvum, and Entamoeba histolytica may be suspected.
These protozoa enter our bodies through contaminated water or food and adhere to or invade the mucosa of the small intestine or large intestine, inducing inflammation. Damage to the mucosa interferes with nutrient absorption and ultimately becomes the primary culprit causing chronic diarrhea and weight loss. The inflammatory response in the gut leads not only to alterations in intestinal motility but also to abdominal distension and gas formation, significantly lowering the patient's quality of life. Unlike simple bacterial enteritis, symptoms of protozoan infection can persist for weeks to months, and they often do not respond well to specific antibiotics or anthelmintics, making professional diagnosis and treatment essential.
Furthermore, gut health is not limited solely to digestive function. The gut is the front line of immunity where about 70% of our body's immune cells are concentrated, and it is called the second brain, where more than 90% of serotonin, known as the happiness hormone, is produced. When the intestinal mucosa is damaged and the balance of gut microbiota is disrupted by protozoan infection, it leads to decreased immunity and also affects neurotransmitter production, which can cause systemic fatigue, lethargy, and even depressive feelings. This situation negatively impacts the gut-brain axis, adversely affecting our mood and cognitive function. Therefore, do not overlook this as simple gut trouble; if symptoms persist for a long time, it is important to visit a clinic for an accurate diagnosis and treatment. Please remember that gut health is directly linked to the health of your entire body.
