Article: Typically, if your blood sugar is out of control, you will feel thirsty constantly. You may be able to down a pitcher of water or tea without even thinking about it, for instance, when normally you'd only drink a glass or two. When the sugar concentration is high in your blood, your kidneys can't pull the sugar out anymore. Your body tries to dilute that sugar by pulling in more water from your tissues, leaving you feeling dehydrated. This makes you feel the urge to drink more water, resulting in you urinating more often. If you're trying to lose weight, dropping pounds isn't a bad thing. However, if you haven't changed your eating or exercising habits recently, suddenly losing weight can be an indicator of diabetes. With type 2 diabetes, your insulin has trouble getting sugar from your blood for energy. Therefore, it starts drawing from your fat and muscle reserves for energy, causing you to lose weight. Keep in mind that not all early diabetics will lose weight. You may gain weight or see no change in your weight, even though you have diabetes. Uncontrolled diabetes can also cause extreme hunger. You may find yourself wanting to snack all the time and in large quantities. At the same time, you may still be losing weight. Typically, this is because your body is having trouble drawing energy from the glucose in your blood, so it's making you want to eat more. With diabetes, you'll have more trouble healing cuts than you normally do. For instance, you may notice that a cut just doesn't seem to be healing over, even after a week or two. You might also get gum or skin infections more often, as well as genital itching caused by fungus or sugar in your urine. Unstable glucose levels can affect your blood circulation, which is why healing takes longer. Uncontrolled blood sugar levels can make you feel tired all the time. This isn't just feeling tired after a long day of work; rather, it's a tiredness that you can't seem to shake no matter how much rest you get. Irritability is a related symptom, as not feeling yourself can make you irritable. Because unstable blood sugar can reduce your circulation, your blood can't get energy and oxygen to your cells. High blood sugar levels may cause changes in your eyes, leading to blurred vision. This symptom may go away if you get your blood sugar under control, but you definitely need to see a doctor. If you experience blurred vision, visit your doctor immediately for a medical evaluation.
