Significant: This amount of weight loss is significant. You definitely need to see your doctor. There might be very different reason from hyperthyroid, diabetes, to cancer.

I understand the far reaching implications of stress. I can only recommend detailed history and examination with supportive laboratory to arrive at an answer.
