Pregnancy after 40 – what are the risks?
Pregnancy imposes a great change in the anatomy and physiology of a woman. The growing fetus has high metabolic requirements and results in weight gain. Hormonal changes associated with pregnancy bring about hemodynamic changes. All organ systems are required to perform at their optimal levels of efficiency. Any major abnormality of organ function may threaten the pregnancy and increase the risk to the mother or the fetus. During young age, organ systems can easily adjust to the increased demands of pregnancy. Though the majority of healthy women after 40 have a normal outcome of pregnancy, with increasing age the capacity of the human body to take up such major stress reduces. Hence, late pregnancy after the age of 40 years is associated with health risks.

How to reduce risks associated with late pregnancy?
Though the risk of pregnancy-associated complications increases after the age of 40, the majority of healthy women deliver a healthy baby and lead normal life. A few steps may be taken to reduce the risk so as to have an uneventful pregnancy, delivery, and post-delivery recovery.
Regular antenatal care: Early weeks of pregnancy are crucial. Formation of organs takes place during the initial 8 to 12 weeks and thereafter growth continues. Antenatal care involves clinical check-up of mother, assessment of health parameters, education of mother, and provision of iron, vitamins including folic acid and calcium supplements. Intake of folic acid prevents birth defects involving the brain and spinal cord. Screening for birth defects is also done.
Post-natal care: After the delivery of the child, care is required so as to return to the pre-pregnancy level of fitness. Gradual build-up of exercise routine with nutrition is essential. Massage therapy also helps in the reduction of any swelling and improves muscle tone. During the lactation period, nutritional supplementation especially with calcium is required.
Balanced diet: Consume a healthy and wholesome diet. This should include plenty of fruits and vegetables. Milk and milk products are a good sources of calcium and protein especially during periods of lactation.
Weight changes during pregnancy: Women with normal weight gain about 12 to 15 kilograms till the completion of pregnancy. One should achieve the recommended weight gain during pregnancy and return to earlier levels in 2 to 3 months after delivery. With weight monitoring and a balanced diet, this is possible. Excessive weight gain increases the risk of hypertension and gestational diabetes.
Regular exercise: Special exercises during pregnancy and after delivery are recommended.
Stop smoking and alcohol absolutely. Consult your doctor before intake any medication including over-the-counter drugs and nutritional supplements.
Late pregnancy is a risk to the mother as well as to the growing baby. Though most of the time all goes well, there is an increased anticipated risk. Physician or midwife guidelines are always recommended to ensure a positive outcome.
