Unexplainable Weight Loss
This may sound like good news, but if you’ve recently dropped a significant amount of weight without trying — or perhaps even while eating more than usual — it may be a sign of diabetes. “Insulin resistance causes sugar to stay stuck in the bloodstream rather than being moved into cells for energy storage,” says Hartley. “With diabetes, your body also loses sugar through urination. Because sugar is a source of energy, or calories, this can lead to weight loss.”
