Insulin resistance does not directly cause fetal arrest, but there is a certain correlation with fetal arrest, itself insulin resistance or pay attention to medication regulation. The symptoms of insulin resistance will not directly cause fetal termination. Insulin resistance itself is not well controlled, may further lead to hyperglycemia; after the emergence of hyperglycemia, it is easy to cause intrauterine distress or fetal developmental abnormalities, which may further lead to the emergence of fetal termination, the corresponding conditions need to be controlled in advance, and some people need to apply insulin during pregnancy. If insulin resistance occurs and is accompanied by a significant rise in blood glucose, it is necessary to consult a doctor for timely observation, determine the specific pancreatic function through blood tests, and administer medication regularly under the guidance of the clinician.
