Most of the diarrhea is a yellowish green watery stool, sometimes like an egg pattern. Fungal infections can be foamy, loose, smelly, pus and bloody; staphylococcal infection can be yellow and green loose, 3 to 20 times a day, accompanied by abdominal distension, abdominal pain is generally not, vomiting and diarrhea can be accompanied by dehydration , electrolyte imbalance, blood urea nitrogen increased, blood pressure decreased.

3. Increased fecal gallbladder excretion in feces: one of the characteristics of jaundice. Astragalus refers to the yellow stain caused by bilirubin deposition in the skin, sclera and diuretic membrane. The normal serum total bilirubin concentration is 1.7~1.71. When one minute of bilirubin (both direct bilirubin) is lower than 3.4 umol/L, when the total bilirubin concentration is 34umol/L, the yellow value appears in clinical practice. When the concentration of bilirubin in the serum exceeds the normal range and the jaundice is not visible to the naked eye, it is called recessive jaundice.
