Modern medicine views cystitis, particularly acute cystitis common in women, primarily as an infection caused by bacteria, especially Escherichia coli, that have invaded the urethra and urinary bladder. Antibiotic therapy is the standard. Yet, there are so many people whose symptoms continually recur even after taking antibiotics. This is a signal that complex internal systems are intertwined beyond just a matter of bacteria.
Translating the concepts of deficiency cold and damp-heat from Donguibogam into modern science allows us to connect them to an **autonomic nervous system imbalance and immune system imbalance** in our body.
First, deficiency cold can signify a state of overall **decreased immunity**. When adrenal function drops and cortisol secretion is disrupted due to stress, chronic fatigue, and sleep deprivation, our body's immune cells cannot function properly. When the immune defense system of the bladder mucosa weakens, even a small amount of bacteria that usually causes no problems can easily trigger inflammation. In particular, a cold lower abdomen can mean that local immunity around the urinary bladder tissues has weakened due to poor blood circulation. Reduced blood flow hinders the supply of immune cells and antibodies while making waste elimination difficult, leaving the area vulnerable to inflammation.
Next, damp-heat can be linked to a **chronic inflammatory response** or **microbiome dysbiosis**. Modern individuals are prone to disrupted gut microbial environments due to processed food consumption, irregular eating patterns, and chronic stress. When gut health deteriorates, intestinal permeability increases, and inflammatory substances can spread throughout the body via the bloodstream, which may affect the bladder mucosa in the process to induce or worsen inflammation. This is also described as the gut-bladder axis. Moreover, excessive calorie intake or an inflammatory diet fosters inflammatory damp-heat in our body, sensitizing the bladder mucosa and increasing vulnerability to bacterial infection. Changes in urine pH or osmotic pressure can also influence bacterial proliferation.
Ultimately, the recurrence of cystitis suggests that beyond simply killing bacteria with antibiotics, a holistic approach is needed to **restore our body's overall immune balance, stabilize the autonomic nervous system, and cultivate a healthy microbiome environment**. Enhancing your body's natural healing capacity can be the true key to breaking free from the relentless cycle of cystitis.
