It is hard to say what is normal weight loss. If you are concerned about the amount of weight you are losing then it would be advisable to see your doctor, so he can weight and measure you, before deciding if it is significant enough to be a worry. There are some things which can cause you to lose weight, such as having high blood glucose levels for a long time or some medical conditions such as an overactive thyroid gland. I am sorry but we really can't say why you are losing weight or whether you should be concerned, but it is best just to check it out with your doctor to be sure.
