My blood sugar is 110 mg/dl, my blood pressure is 140/90, I do experience palpitations,nervousness and sometimes anxiety. I am also constipated most of the times. I urge to drink water and go to the restroom most of the time. And I feel like I'm always hungry. I also have a tingling sensation on my hands and feet,when I bend,my legs do have tremors. And I am just 21 years old. What is this all about? Thank you.
