Focusing on a patient case with recurrent ocular hyperemia and stomatitis: An interpretation of preclinical autoimmunity and the Korean medicine perspective

Hello. This is Baengnokdam Korean Medicine Clinic.

Puzzling, Unexplained Symptoms

Have you ever experienced something like this?

You wake up in the morning to find your eyes bloodshot, and your mouth is sore with ulcers. It stings every time you brush your teeth, and when you look in the mirror, you see small ulcers on your tongue. At first, you might think it's just a cold, but as this pattern keeps repeating, you start to realize that these aren't just temporary symptoms.

You go to the hospital and get a blood test, but the doctor tells you, "Your numbers are normal." And it ends with advice to take some supplements, as you might be lacking vitamins. But your body is clearly telling you something—that something is wrong.

Today's post is for exactly these people. We'll explore the true language of the body hidden behind recurrent ocular hyperemia and oral inflammation.

Recurring Symptoms, Not Detected by Tests

This is the story of someone I met in my clinic. She was a woman in her mid-30s. She had quite a lot of stress from work, frequent late nights, and sleep deprivation. But strangely, whenever she was tired, her mouth would get sore, and her eyes would become bloodshot.

She tried taking vitamins and used eye drops from an ophthalmologist, but after a few weeks, the same symptoms would recur. Greyish-white ulcers, 2-3mm in size, would appear in her mouth, and her eyes would be bloodshot and accompanied by a stinging sensation. However, her CBC (Complete Blood Count), liver enzyme levels, inflammatory markers, and autoimmune antibody tests were all normal.

"What exactly is wrong?"

The answer to that question was always the same.

"Numerically, there's no problem."

But that wasn't what her body was saying. The real message was already expressed through her eyes, mouth, and persistent fatigue.

The Eyes and Mouth are Connected: Anatomical Continuity and Shared Innervation

Let's start by asking this question. Why specifically the 'eyes' and 'mouth'? Why do these two areas have problems simultaneously?

From a modern anatomical perspective, the eyes, mouth, nose, pharynx, and trachea are all connected by a single mucous membrane pathway. Tears flow into the nose, the mouth and nose are connected via the pharynx, and below that, it connects to the trachea. What this means is that if inflammation or irritation occurs in one area, other areas along the same mucosal structure can easily be affected.

The conjunctiva of the eye, the oral mucosa of the mouth, and the pharyngeal mucosa of the throat are all part of 'MALT' (Mucosa-Associated Lymphoid Tissue), which shares immune surveillance. Another important connection is the nervous system. The eyes and mouth are connected sensorily through branches of the trigeminal nerve, and they also receive autonomic nervous system regulation. When the sympathetic nervous system is overactive due to stress, blood vessels in the eyes dilate and become congested, and the oral mucosa becomes dry, making it prone to developing small ulcers. In other words, the eyes and mouth aren't hurting separately; a single network is reacting simultaneously.

If the Numbers are Normal, Is It Not a Disease? The Gray Zone of Immunity

Let's go back to the original question. Why does the body feel sick even when blood tests are normal? This is a very important concept immunologically. Most autoimmune diseases in our body "develop gradually." That is, the body is quietly changing long before the "diagnosable point" when antibodies appear and tissue destruction begins. This is called 'preclinical autoimmunity'.

During this period, autoantibodies may be present at low levels, or only mucosal immunity may react locally, or autonomic nervous system dysregulation may begin first. A typical immune activation pattern is the Th17 pathway, which primarily triggers reactions in mucosal and integumentary systems like the eyes, mouth, intestines, and skin, through cytokines such as IL-17 and IL-22. As a result, nothing is detected in the blood, but the body is already expressing inflammation.

Do you know what patients like this often hear?

"It's psychosomatic." "You're just tired."

But this is neither psychosomatic nor "just" anything. This is the body's first expression before it becomes a full-blown illness.

How Does Korean Medicine Address This Gray Zone?

It is precisely at this point that the role of Korean medicine begins. For a long time, Korean medicine has referred to such conditions by names like 'Sangcho Yeol' (Heat in the Upper Burner), 'Ganhwa Sangyeom' (Ascending Liver Fire), 'Wi Yeol Sang Gong' (Ascending Stomach Heat), or 'Eumheo Hwadong' (Yin Deficiency with Heat Agitation).

For example, when under severe stress, Liver Fire may ascend, leading to symptoms like red eyes, oral ulcers, and a feeling of tightness in the chest. Overeating or overwork can cause Stomach Heat to rise, resulting in a swollen tongue, dry mouth, and a stinging sensation in the eyes. Or, a state where Yin and Blood are depleted and Deficiency Fire rises due to lack of sleep or chronic fatigue.

While these patterns are described in Western medicine as inflammation, autonomic nervous system dysfunction, and immune hypersensitivity reactions, Korean medicine assesses the direction and location of symptoms, even without numerical values, and initiates treatment. This means intervention is possible from the stage of 'signs' rather than a full-blown 'disease.' This is how Korean medicine has evolved over thousands of years, treating 'mibyeong' (pre-symptomatic or sub-health conditions).

Treatment Begins With Understanding the Depth of the Symptoms

When both the eyes and mouth are acting up, it's not just a problem with two separate organs. It's a sign that the body's overall immune balance, autonomic nervous system state, and mucosal function are simultaneously compromised. If you ignore this, in a few years, it could lead to autoimmune diseases like Sjögren's, Behçet's, or Lupus, or chronic syndromes such as chronic fatigue, gastroenteritis, dry eyes, and insomnia.

Therefore, it's crucial to take these minor symptoms seriously and to develop the skill to interpret signals that haven't yet been given a specific name.

The Body Is Always Speaking

We often only focus on the name of a disease, but the body is always communicating something before that. When your eyes are red and your mouth is sore, it's not just a minor discomfort, but a sign that the balance of your immune system, autonomic nervous system, and metabolism is disrupted. And if you can read those signs, you can stop the progression before it becomes a full-blown illness.

That's why we're having this discussion, and if there's a way to help with that, I believe Korean medicine must be there.
