If you haven’t had labs in a while, it may be time to check on your kidney and liver function. In addition, medication side effects need to be looked at. So, you should see your doctor to evaluate unexpected weight gain, especially if you are taking in low calories. A tumor is always possible but there are other possibilities that need to be explored as well. So, see your doctor. Good luck!
