One, Key points of differentiation
1, Different etiologies can lead to different patterns and different characteristics of feces. Generally, loose stools with milk clumps or food residue, with an acidic and foul smell, or like rotten eggs, are often caused by injury to the breast or food. Clear and thin stools with a light yellow color and not much smell are often caused by wind-cold. Watery or egg flower soup-like stools, with a large amount, a yellow-brown color, and a foul smell, or with a little mucus, with abdominal pain, are mostly caused by damp-heat. Loose or runny stools, light in color and odorless, occur more after eating, which is due to spleen deficiency. Clear and thin stools without undigested grains, light in color and odorless, mostly belong to deficiency of both the spleen and kidney.
2, The frequency of defecation is generally not more than 10 times, with good spirits, no vomiting, and adequate urine volume, which belongs to mild symptoms. If diarrhea is acute and severe, with frequent and large amounts, and the spirit is萎靡or restless, or there is vomiting, with short and little urine, it belongs to severe symptoms. If there are signs such as dry and withered skin, sunken fontanelle, crying without tears, little or no urine, pale complexion, and debilitated spirit, it indicates a critical and severe change in diarrhea.
3. Differentiating between deficiency and excess in diarrhea with a short course, urgent and violent diarrhea, large volume, abdominal pain, mostly belong to excess. Diarrhea for a long time, slow diarrhea, abdominal distension and preference for pressure, mostly belong to deficiency. Prolonged and difficult to recover, diarrhea is either urgent or slow, abdominal distension and pain is resistant to pressure, mostly belong to deficiency with excess.
Second, treatment principles
Treatment of diarrhea: The basic principle is to transform the spleen and drain dampness. For实证, the main treatment is to expel pathogenic factors, treating different patterns with eliminating food retention and promoting digestion, dispersing wind and cold, and clearing heat and promoting diuresis. For虚证, the main treatment is to reinforce the body's resistance, treating with invigorating the spleen and qi, and warming the spleen and kidney. For diarrhea with varying conditions, treat with invigorating qi and nourishing yin, acid-sweet retaining yin, protecting yin and reversing yang, and rescuing and consolidating. In addition to internal medication, external treatment, massage, acupuncture, and other methods are often used to treat this disease.
1. Diarrhea due to overeating
Syndrome: Loose stools with milk lumps or food residue, acid and foul smell, or like rotten eggs, abdominal distension, pain before defecation, pain reduces after defecation, abdominal pain is resistant to palpation, belching with sour smell, or vomiting, loss of appetite for milk and food, restless sleep at night, thick and greasy tongue coating, or slightly yellow.
Analysis: This syndrome often has a history of irregular milk and food intake. Irregular milk and food intake injures the spleen and stomach, causing malfunctions in transformation, hence the loose stools with undigested milk lumps or food residue. Food retention in the middle-jiao leads to qi stagnation, causing abdominal distension and abdominal pain; after defecation, the accumulation decreases, and the qi mechanism is temporarily unobstructed, hence the temporary relief of abdominal pain after defecation. Internal corruption of milk and food, turbid qi rising, the stomach loses its normal descending function, causing belching with sour smell, or vomiting. Thick and greasy tongue coating or slightly yellow, acid and foul stools, or like rotten eggs, loss of appetite for milk and food, restless sleep at night, are all signs of milk and food retention.

Wind-cold depression blocks the qi mechanism, causing intestinal rumbling and abdominal pain. Chills, fever, clear nasal discharge, cough, pale tongue, thin white coating are all signs of wind-cold invasion from the exterior.
