effects of drugs on pregnet women
Pregnant women that smoke cigarettes on a daily basis can greatly harm their fetus. The Tobacco smoke in cigarettes greatly reduces fetal growth through the presence of nicotine, carbon monoxide, hydrogen cyanide, cadmium and various other aromatic hydrocarbons, but the two most dangerous chemicals that are found in cigarettes are nicotine and carbon monoxide. Nicotine causes the babies heart rate to speed up, reduces placental vascularisation, constricts the placental arteries, and thickens the endothelium of placental blood vessels. This creates a reduction in the placental blood flow, and further reductions in oxygen delivery. As well nicotine interferes with the ability of the placenta to feed the baby the nutrients it requires. Therefore the babies growth is slowed down. Carbon monoxide causes growing cells to be starved of oxygen, and effects the brain. This can lead to a low birth weight and higher chance of the baby dying at birth. Smoking is the single largest modifiable( changeable) risk factor in fetal growth retardation. Maternal smoking during pregnancy is also associated with genetic defects as well as an increased incidence of congenital malformations such as cleft palates, microcephalus, and clubfoot. Mothers who s
One type of medicine that pregnant woman should avoid is Benzodiazepines, which are anti anxiety medication. Benzodiazepines rapidly cross the placenta barrier and enter the fetal circulation. Blood levels in the fetus equal that of the mother's within one hour of taking the Benzodiazepine pill. Some Benzodiazepines may cause respiratory depression, hypotonia, lethargy, and poor feeding. Pregnant women should as well be aware of the medicines and medicinal drugs that they take during their pregnancy. Pregnant women should also try to stay away from high concentrations of organic solvents, and cleansers. These substances can greatly harm the fetus. Some common examples of organic solvents, and cleansers that should be avoided are household cleaners and gasoline. Volatile organic solvents have been shown to have teratogenic effects on the growing fetus, such as physical malformations or functional impairment.. Inhaled solvents reduce oxygen levels in the body tissue thus reducing oxygen supply to the fetal brain. If the pregnant mother inhales at high doses, then she can cause the death of the fetus. moke one pack a day during pregnancy have an 85% increased risk of having a child with mental retardation. Mothers that smoke during their pregnancy have double the chance of having a child with behavural problems. It is extremely important that pregnant women eat proper foods with essential nutrients and a well balanced diet. This is important becaus
