Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Methamphetamine is a dangerous substance that can harm a woman’s body and put her at risk for maternal complications. For example, women who abuse Methamphetamine tend to have a significantly lower body mass index (BMI). This can make her pregnancy riskier. One study found that lower BMI increased a woman’s chance for pregnancy complications, including more frequent hospitalizations and longer hospital stays. The anorectic effects of Methamphetamine can also result in intrauterine growth retardation (poor growth of the fetus in the womb). Using Methamphetamine during pregnancy can also reduce a woman’s placental blood flow. This can cause fetal hypoxia, an insufficient amount of oxygen to the fetus. Also can cause increased mortality in the mother and her child. Retinal defects. Cleft palate. Malformations of the ribs. Slowed physical growth. Delayed motor development. Stop it immediately. Take care. Hope my answer was helpful, if you have any other questions I ll be glad to help you.
