Weakness is a common symptom of hepatitis patients, and its main causes are: 1, cholinesterase decrease: cholinesterase is the medium of excitation conduction between human nerve and muscle, produced by liver cells, when hepatitis, due to hepatocyte lesions, liver function decreases, cholinesterase synthesis is reduced; at the same time, when hepatitis, but only excretion is blocked, bile salt in the bile is retained in the body, and bile salt has the effect of inhibiting the body cholinesterase, cholinesterase Decrease can cause nerve-muscle conduction dysfunction, therefore, the patient will feel tired and weak; 2, sugar metabolism disorders: liver is the organ of synthesis of glycogen, hepatitis, the body lactic acid into glycogen process is slower than normal, the body lactic acid accumulation, can make the patient feel muscle swelling, fatigue; 3, vitamin E deficiency: liver is the main storage site of vitamin E, hepatitis due to abnormal bile excretion The vitamin E is a fat-soluble vitamin, so its absorption is also significantly reduced, and vitamin E has the role of regulating the body’s enzyme system, can reduce the oxygen consumption in the body tissues, which is conducive to enhance the tolerance of the body’s tissues to the low oxygen state, vitamin E deficiency increases muscle oxygen consumption, can cause muscle malnutrition and weakness; 4, hepatitis patients with vitamin B and protein deficiency, electrolyte disorders (such as low potassium, low sodium, etc.), ovarian or testicular hypofunction, can make patients appear weak. Therefore, hepatitis patients, especially patients with chronic hepatitis or cirrhosis, appropriate high-protein diet, oral vitamin E and B is very necessary.
