In general, women live longer than men do because they have a lower risk of heart disease, but when women develop diabetes, their risk for heart disease skyrockets, and death by heart failure is more likely in women than in men. Another study also found that in people with diabetes, heart attacks are more often fatal for women than they are for men. Other examples of how diabetes affects women differently than men are:
Random blood sugar test. A blood sample will be taken at a random time. Blood sugar values are expressed in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). Regardless of when you last ate, a random blood sugar level of 200 mg/dL (11.1 mmol/L) or higher suggests diabetes, especially when coupled with any of the signs and symptoms of diabetes, such as frequent urination and extreme thirst.
In type 2 diabetes (formerly called non– insulin-dependent diabetes or adult-onset diabetes), the pancreas often continues to produce insulin, sometimes even at higher-than-normal levels, especially early in the disease. However, the body develops resistance to the effects of insulin, so there is not enough insulin to meet the body’s needs. As type 2 diabetes progresses, the insulin-producing ability of the pancreas decreases.
The amount of glucose in the bloodstream is tightly regulated by insulin and other hormones. Insulin is always being released in small amounts by the pancreas. When the amount of glucose in the blood rises to a certain level, the pancreas will release more insulin to push more glucose into the cells. This causes the glucose levels in the blood (blood glucose levels) to drop.
What medication is available for diabetes? Diabetes causes blood sugar levels to rise. The body may stop producing insulin, the hormone that regulates blood sugar, and this results in type 1 diabetes. In people with type 2 diabetes, insulin is not working effectively.

On behalf of the millions of Americans who live with or are at risk for diabetes, we are committed to helping you understand this chronic disease. Help us set the record straight and educate the world about diabetes and its risk factors by sharing the common questions and answers below. If you're new to type 2 diabetes, join our Living With Type 2 Diabetes program to get more facts.
A random blood sugar of greater than 11.1 mmol/l (200 mg/dl) in association with typical symptoms or a glycated hemoglobin (HbA1c) of ≥ 48 mmol/mol (≥ 6.5 DCCT %) is another method of diagnosing diabetes. In 2009 an International Expert Committee that included representatives of the American Diabetes Association (ADA), the International Diabetes Federation (IDF), and the European Association for the Study of Diabetes (EASD) recommended that a threshold of ≥ 48 mmol/mol (≥ 6.5 DCCT %) should be used to diagnose diabetes. This recommendation was adopted by the American Diabetes Association in 2010. Positive tests should be repeated unless the person presents with typical symptoms and blood sugars >11.1 mmol/l (>200 mg/dl).
Yet carbs are processed differently in the body based on their type: While simple carbs are digested and metabolized quickly, complex carbs take longer to go through this system, resulting in more stable blood sugar. “It comes down to their chemical forms: A simple carbohydrate has a simpler chemical makeup, so it doesn’t take as much for it to be digested, whereas the complex ones take a little longer,” Grieger explains.
In type 1 diabetes, other symptoms to watch for include unexplained weight loss, lethargy, drowsiness, and hunger. Symptoms sometimes occur after a viral illness. In some cases, a person may reach the point of diabetic ketoacidosis (DKA) before a type 1 diagnosis is made. DKA occurs when blood glucose is dangerously high and the body can't get nutrients into the cells because of the absence of insulin. The body then breaks down muscle and fat for energy, causing an accumulation of ketones in the blood and urine. Symptoms of DKA include a fruity odor on the breath; heavy, taxed breathing; and vomiting. If left untreated, DKA can result in stupor, unconsciousness, and even death.
Excessive thirst typically goes hand-in-hand with increased urination. As your body pulls water out of the tissues to dilute your blood and to rid your body of sugar through the urine, the urge to drink increases. Many people describe this thirst as an unquenchable one. To stay hydrated, you drink excessive amounts of liquids. And if those liquids contain simple sugars (soda, sweet iced tea, lemonade, or juice, for example) your sugars will skyrocket even higher.
If genetics has taught us anything about diabetes, it's that, for most people, genes aren't the whole story. True, a few rare kinds of diabetes—including those collectively called MODY for maturity-onset diabetes of the young—have been traced to defects in a single gene. But for other types of diabetes, hereditary factors are still not well understood.
How does high blood sugar (hyperglycemia) feel? To maintain the right amount of blood sugar, the body needs insulin, a hormone that delivers this sugar to the cells. When insulin is lacking, blood sugar builds up. We describe symptoms of high blood sugar, including fatigue, weight loss, and frequent urination. Learn who is at risk and when to see a doctor here.

Abnormal cholesterol and triglyceride levels. If you have low levels of high-density lipoprotein (HDL), or "good," cholesterol, your risk of type 2 diabetes is higher. Triglycerides are another type of fat carried in the blood. People with high levels of triglycerides have an increased risk of type 2 diabetes. Your doctor can let you know what your cholesterol and triglyceride levels are.
