Abstract: In high risk women for fetal growth restriction，healthy diet and balanced energy and protein supplementation reduce the risk of small-for-gestational-age infant.Supplementation of multiple micronutrients in malnourished mothers may reduce the incidence of low-birth-weight and small-for-gestational-age infant.Low-dose aspirin can reduce the risk of fetal growth restriction.Whether low molecular heparin can prevent fetal growth restriction needs further study，but no serious adverse reactions of low molecular heparin have been observed.Once the diagnosis of fetal growth restriction is confirmed，no treatment will improve fetal growth.There is no evidence that bed rest，nutritional supplementation，oxygen therapy or volume expansion has therapeutic effect on fetal growth restriction，and there is no clear evidence that low molecular heparin plays a role in the treatment of fetal growth restriction；however，potential therapies aiming at improving poor uteroplacental perfusion are under research，such as nitrate supplementation，beta-agonists，sildenafil，hydrogen sulfide，statins and melatonin.
