Losing weight in early pregnancy might seem alarming but it's fairly common, particularly due to bouts of morning sickness. Often, this is nothing to worry about, especially if the weight loss is short-lived, minimal, and followed by the recommended weight gain. However, losing weight while pregnant is cause for concern if the weight loss is substantial, long-lasting, or occurs after the first trimester.
In those cases, losing weight while pregnant can be problematic, can cause health complications for you and your baby, and will need medical attention. Your medical provider will track your weight gain or loss at every prenatal check-up for this very reason. Below, we explore why pregnancy weight loss occurs, when to be concerned, and what to do about it.
