Would it be obvious if I have diabetes?
Some of the symptoms of diabetes are things you might be able to detect yourself, such as thirst and frequent urination. However, to be officially diagnosed (or given a clean bill of health), you'll need to see a health professional. See the following links for more info:
Diabetes is considered as a metabolic disorder which affects the ability of body to use or make insulin. It raises blood sugar levels and causing many health problems in life. They are generally categorized in four stages i.e. pre-diabetes, type 1, type 2, and gestational. If you have symptoms like mentioned in this post http://chippewa.com/news/local/diabetes-warning-signs/article_d4c3849e-421b-11e0-94ce-001cc4c002e0.html then you have to go for diabetic test to confirm whether you have the disease or not.
