High glycolic acid may indicate hepatobiliary disease or may be due to physiologic factors. Contraindications vary according to the cause. Generally, avoid overeating, avoid spicy, greasy, high-fat food. 1. Liver and gallbladder diseases: glycolic acid is mainly synthesized in the liver, and when liver cells are damaged, serum glycolic acid is elevated. Spicy, greasy and high-fat diet should be avoided, and overeating should be avoided. In addition, those with advanced liver cancer with poor liver function should limit protein intake; those with mild liver injury do not need to limit protein intake; patients with ascites should have less salt or salt-free diet; patients with esophagogastric fundal varices should abstain from eating fried foods, nuts and other hard foods. 2. Physiological factors: if pregnant women with elevated glycolic acid is a normal phenomenon, generally not more than 10mg / L, when abnormally high, need to be alert to intrahepatic cholestasis in pregnancy. When bile acid is high, you should consult a doctor in time to clarify the cause of the disease, and under the guidance of the doctor, adopt the dietary structure recommended by the doctor.
