Good afternoon doctor My name is Francesca Joynt and I m not sure if I have diabetes or not but there are a few things I m worried about: I m fat, I m always yawning during the day, I have cravings for junk food and can t get through a day without some form of junk food/drink, I have a a strange yucky feeling in my mouth, I m not a very healthy person and I can get tired and exhausted very easily ( I do go to the gym but sometimes it s hard to motivate myself to go ) Can you give me some advice on what to do, can you help me.
