What is considered a relative contraindication to exercise during pregnancy?

In the context of exercise during pregnancy, relative contraindications refer to conditions under which exercise may still be permissible but must be approached with caution and close monitoring. Well-controlled type 1 diabetes is an example of a relative contraindication because, while there are potential risks associated with exercise during pregnancy, with proper management and oversight by a healthcare provider, many women with well-controlled diabetes can engage in physical activity safely. Exercise can actually help in managing blood glucose levels and can provide several health benefits during pregnancy.

In contrast, severe preeclampsia, placental abruption, and active preterm labor are classified as absolute contraindications to exercise, meaning that engaging in physical activity is strongly discouraged due to the significant risks they pose both to the mother and the fetus. Each of these conditions indicates a serious complication that could lead to adverse outcomes, thereby necessitating a cessation of exercise until the condition is resolved or closely monitored.
