When the crops slowly dry up, we need to see if the land is dry. The damage of dry syndrome can be divided into “external manifestations” (withered crops) and “internal damage” (dry land). The external manifestation is the manifestation that the patient can feel/observe, which is the physical experience. Intrinsic damage, which is the damage to the internal organs of the disease, is often not easily felt/realized and easily ignored, so it is the key hidden problem that we focus on. External manifestations, including dry eyes, dry mouth, joint pain, etc., may also have skin lesions, constipation, dry reproductive tract, etc. (1) Dry mouth. It manifests as dry mouth, or the need to drink water frequently when speaking, or the need to drink water to deliver when eating solid food, or the need to get up to drink water at night, etc. Some patients have severe dental caries and tooth decay (saliva has the function of cleaning the mouth and moistening the gums), some patients have dry, dry and cracked tongue and increased mouth ulcers. Some patients have indigestion (saliva can help digestion). (2) Dry eyes. The eyes are dry and uncomfortable, or foreign body sensation, or few tears, or even “no tears to cry”, which can be followed by keratitis, conjunctivitis, corneal perforation, or even blindness. (3) Some people have vaginal dryness that affects their sex life, and some people have difficulty in passing stools due to dryness of the colon. (4) Some people have joint pain. However, it should be noted that we often encounter these patients being misdiagnosed as “rheumatoid arthritis” due to arthralgia, leading to deviations in treatment. (5) Skin manifestations. Some people have red spots on the skin, or bumps under the skin, or fingers that turn white and purple when they are cold. Internal hazards, including kidney, liver, lung, gastrointestinal, nervous system, blood cells, blood vessels, etc. Also easily overlooked are: psychic/psychological problems, “acidic body fluids”, susceptibility to cancer, etc. (1) Kidney: 40% of patients have kidney damage, which destroys the distal renal tubules and reduces the kidney’s ability to eliminate acidic substances, causing “acidic body fluids” while excreting important minerals such as calcium and potassium. This can lead to urinary stones, polyuria, excessive drinking, and increased nocturia. Some patients also develop proteinuria, hematuria, etc. The early and middle stages of renal lesions in this disease do not cause creatinine to rise, so normal renal function on physical examination does not equal no lesions in the kidneys. (2) Liver and gallbladder: there may be elevated transaminases and elevated globulin, and a small number of people may have cirrhosis of the liver and gallstones. (3) Lungs: may have dry cough, shortness of breath, pulmonary fibrosis (lungs are hardened and less elastic). (4) Gastrointestinal: may have atrophic gastritis, bloating, indigestion, chronic pancreatitis, etc. (5) Blood cells: some people have reduced platelets, reduced white blood cells, etc. (6) Mind/psychological problems. Because the “mind is chronically lack of internal fluid nourishment”, patients are prone to spiritual/psychological/personality problems. They may be impatient, irritable, suspicious, overly worried about everything, poor sleep, etc. Patients and family members often do not realize that this is the disease “at work”, or simply do not recognize it, or misinterpret it as “menopause”. According to our practice, it is not uncommon to see family conflicts and contradictions that are fuelled by this. (7) Acidic body fluids can cause the loss of calcium in the bones of patients (it is understood that experienced housewives will add vinegar to bone broth because acetic acid can help boil out the calcium in the bones), which will lead to osteoporosis over time, and in severe cases, people are prone to fracture (incredibly) at the slightest fall, and it is difficult to heal fractures. In addition, people with osteoporosis are more afraid of cold. (8) Cancer. Patients are prone to cancer, and malignant lymphoma is particularly common. These cancers often have some “first signs” before they occur, so physicians should conduct detailed examinations and analysis in order to detect and extinguish the “first signs” at an early stage.
