How to remedy a small fetal head? In order to remedy the small head of the fetus, we must first clarify the cause of the small head of the fetus. There are two main reasons for a small fetal head: physiological reasons: 1. measurement errors: ultrasound sometimes has measurement errors; 2. genetic predisposition: if the parents have a small head, it is also possible that the fetus has a small head; 3. poor nutrition: caused by malnutrition. Pathological causes: This condition requires a careful search for the cause to identify genetic factors, infections, perinatal asphyxia, exposure to toxic substances and metabolic disorders, among other causes. The focus should be on preventing the possibility of microcephaly. How to remedy: Remedy for physiological causes: If the head is not too small, the main thing is to observe, as long as this gap does not increase 1, measurement error: mainly through the review to correct the error 2, genetic predisposition: observation is the main thing, as long as the gap does not increase, it is fine. 3, poor nutrition: appropriate supplementation. Pay attention to calcium and protein supplementation. Pathological causes: Once the pathological factors are clearly identified, it is actually difficult to remedy them, and these factors are usually formed from the early stages of pregnancy. 1, genetic factors: If there are problems with chromosomes and other genetics, a comprehensive analysis should be made according to the size of the chromosomal problem, and if it is more serious, the fetus needs to be abandoned. 2, infection: according to the different types of infection for treatment to reduce the impact as much as possible 3, exposure to toxic substances and metabolic disorders: it is difficult to deal with.
