How Do I Know If I Have Diabetes?
Your doctor may suspect you have diabetes if you have some risk factors for diabetes, or if you have high levels of blood sugar in your urine. Your blood sugar (also called blood glucose) levels may be high if your pencreas is producing little or no insulin (type 1 diabetes), or if the body is not responding normally to insulin (type 2 diabetes).
Getting diagnosed begins with one of three tests. in most cases, your doctor will want to repeat a test that is high in order to confirm the diagnosis:
A fasting glucose test is a test of your blood sugar levels taken in the morning before you have eaten. A level of 126 mg/dL or higher may mean that you have diabetes.
An oral glucose tolerance test (OGTT) entails drinking a beverage containing glucose and then having your blood glucose levels checked every 30 to 60 minutes for up to 3 hours. If the glucose level is 200 mg/dL or higher at 2 hours, then you might have diabetes.
The A1c testis a simple blood test that shows your average blood sugar levels for the past 2-3 months. An A1c level of 6.5% or higher may mean you have diabetes.
Diabetes Drugs
If you have type 1 diabetes, your pancreas no longer makes the insulin your body needs to use blood sugar for energy. You will need insulin in the form of injections or through use of a continuous pump. Learning to give injections to yourself or to your infant or child may at first seem the most daunting part of managing diabetes, but it is much easier that you think.
Some people with diabetes use a computerized pump -- called an insulin pump -- that gives insulin on a set basis. You and your doctor program the pump to deliver a certain amount of insulin throughout the day (the basal dose). Plus, you program the pump to deliver a certain amount of insulin based on your blood sugar level before you eat (bolus dose).
Injectable insulin comes in five types:
Rapid-acting (taking effect within a few minutes and lasting 2-4 hours)
Regular or short-acting (taking effect within 30 minutes and lasting 3-6 hours)
Intermediate-acting (taking effect in 1-2 hours and lasting up to 18 hours)
Long-acting (taking effect in 1-2 hours and lasting beyond 24 hours)
Ultra-long-acting (taking effect in 1-2 hours and lasting 42 hours)
A rapid-acting inhaled insulin (Afrezza) is also FDA-approved for use before meals. It must be used in combination with long-acting insulin in patients with type 1 diabetes and should not be used by those who smoke or have chronic lung disease. It comes as a single dose cartridge. Premixed insulin is also available for people who need to use more than one type of insulin.
Degludec (Tresiba) is a once-daily, long-acting insulin, providing a basal dose of insulin lasting beyond 42 hours. (It the only basal insulin approved for both type 1 and type 2 diabetes in patients as young as 1 year old.) It is also available in combination with rapid-acting insulin (Ryzodeg 70/30).
Each treatment plan is tailored for the person and can be adjusted based on what you eat and how much you exercise, as well as for times of stress and illness.
By checking your own blood sugar levels, you can track your body's changing needs for insulin and work with your doctor to figure out the best insulin dosage. People with diabetes check their blood sugar up to several times a day with an instrument called a glucometer. The glucometer measures glucose levels in a sample of your blood dabbed on a strip of treated paper. Also, there are now devices, called continuous glucose monitoring systems (CGMS), that can be attached to your body to measure your blood sugars every few minutes for up to a week at a time. But these machines check glucose levels from skin rather than blood, and they are less accurate than a traditional glucometer.
Your doctor may also suggest a zinc transporter 8 autoantibody (ZnT8Ab) test. This blood test -- along with other information and test results -- can help determine if a person has type 1 diabetes instead of another type. The goal of having the ZnT8Ab test is a prompt and accurate diagnosis and that can lead to timely treatment.
What Are the Treatments for Diabetes?
Diabetes is a serious disease that you cannot treat on your own. Your doctor will help you make a diabetes treatment plan that is right for you -- and that you can understand. You may also need other health care professionals on your diabetes treatment team, including a foot doctor, nutritionist, eye doctor, and a diabetes specialist (called an endocrinologist).
Treatment for diabetes requires keeping close watch over your blood sugar levels (and keeping them at a goal set by your doctor) with a combination of medications, exercise, and diet. By paying close attention to what and when you eat, you can minimize or avoid the "seesaw effect" of rapidly changing blood sugar levels, which can require quick changes in medication dosages, especially insulin.
For some people with type 2 diabetes, diet and exercise are enough to keep the disease under control. Other people need medication, which may include insulin and an oral drug.
Drugs for type 2 diabetes work in different ways to bring blood sugar levels back to normal. They include:
Drugs that increases insulin production by the pancreas, including chlorpropamide (Diabinese), glimepiride, (Amaryl), glipizide (Glucotrol), glyburide (Diabeta, Micronase), nateglinide (Starlix), and repaglinide (Prandin)
Drugs that decrease sugar absorption by the intestines, such as acarbose (Precose) and miglitol (Glyset)
Drugs that improve how the body uses insulin, such as pioglitazone (Actos) and rosiglitazone (Avandia)
Drugs that decrease sugar production by the liver and improve insulin resistance, like metformin (Glucophage)
Drugs that increase insulin production by the pancreas or its blood levels and/or reduce sugar production from the liver, including albiglutide (Tanzeum), alogliptin (Nesina), dulaglutide (Trulicity), linagliptin (Tradjenta), exenatide (Byetta, Bydureon), liraglutide (Victoza), lixisenatide (Adlyxin), saxagliptin (Onglyza), and sitagliptin (Januvia)
Drugs that block the reabsorption of glucose by the kidney and increase glucose excretions in urine, called sodium-glucose co-transporter 2 (SGLT2) inhibitors. They are canaglifozin (Invokana), dapagliflozin (Farxiga), and empagliflozin (Jardiance).
Pramlinitide (Symlin) is an injectable synthetic hormone. It helps lower blood sugar after meals in people with diabetes who use insulin.
Some pills contain more than one type of diabetes medication. They include the recently approved empagliflozin/linagliptin (Glyxambi). It combines a SGLT2 inhibitor that blocks reabsorption of glucose into the kidneys with a DPP-4 inhibitor which increases hormones to help the pancreas produce more insulin and the liver produce less glucose.
Nutrition and Meal Timing for Diabetes
Eating a balanced diet is vital for people who have diabetes, so work with your doctor or dietitian to set up a menu plan. If you have type 1 diabetes, the timing of your insulin dosage is determined by activity and diet. When you eat and how much you eat are just as important as what you eat. Usually, doctors recommend three small meals and three to four snacks every day to maintain the proper balance between sugar and insulin in the blood.
A healthy balance of carbohydrates, proteins, and fats in your diet will help keep your blood glucose on target. How much of each will depend on many factors, including your weight and your personal preferences. Watching your carbohydrates -- knowing how much you need and how many you are eating -- is key to blood sugar control. If you are overweight, either a low-carbohydrate, low-fat/low calorie, or Mediterranean diet may help you get your weight to goal. No more than 7% of your diet should come from saturated fat, and you should try to avoid trans fats altogether.
