(NEW YORK) – Diabetes is one of the most common chronic conditions in the U.S.. today, with almost 30.3 million people suffering from difficulties in managing their blood sugar.
It is the seventh leading cause of death, and the no. 1 leading cause of kidney failure, adult-onset blindness, and lower limb amputation.
Most people with diabetes have Type 2 diabetes, which is often associated with lifestyle choices and genetics. Insulin properly or can not make enough.
About 1.25 million suffer from Type 1 diabetes, which is due to autoimmune disorder. It's the result of the pancreases not making any insulin.
Both conditions result in a body's glucose or sugar levels, but due to very different reasons.
Since November is Diabetes Awareness Month, it is a good time to answer frequently asked questions about the disease.
What is diabetes?
So let's start with what happens in a normal person without diabetes. When you eat a meal, it begins to digest into protein, sugar and fat.
An organ called the pancreas senses the absorbed sugar and produces a hormone called insulin, which then pulls the sugar – or glucose – from the food you just ate and into different parts of your body so that it can be used for energy.
In diabetes, your body either does not make enough insulin or can not use it as well as it should. If you do not have enough insulin, too much glucose stays in the bloodstream, which can cause serious health problems over time, such as heart disease, kidney disease or vision loss.
What is the difference between Type 1 and Type 2 diabetes?
Type 1 diabetes
In patients with Type 1 diabetes (T1DM), their pancreas is unable to produce insulin at all, due to an autoimmune condition. People are more frequently diagnosed when they are children or young adults, and symptoms often develop quickly. They may report feeling very thirsty, going to the bathroom very often, losing weight even though they are normally, and feeling very exhausting.
People with T1DM need to take insulin every day, and currently, there is no known way to prevent or cure T1DM. They make up their blood glucose levels several times a day, at night, and give themselves multiple times a day.
Can I get T1DM?
T1DM has now been thought to be the only one of its kind in children and what has been described as "juvenile diabetes." It is not something contagious, or related to your lifestyle. Rather, it is due to an autoimmune condition, it is an autoimmune condition, and it is destroys the pancreas' ability to produce insulin.
Type 2 diabetes
In patients with Type 2 diabetes (T2DM), either the insulin or their pancreas is insulin. Their body has a hard time keeping the blood glucose at normal levels.
T2DM is not caused by eating sugar itself, but by a variety of lifestyle factors and genetics.
Can I get T2DM?
This is the common adult form of diabetes, and unfortunately, the numbers of affected people, including children, in the U.S., continues to rise. This type of diabetes is associated with obesity, high blood pressure, high cholesterol, or a family history of T2DM.
If you have any of these conditions, it is important to see your doctor.
Can I tell if I have diabetes? How is it diagnosed?
Most commonly, it is diagnosed with a blood test – or a high glucose level before you eat or something called a hemoglobin A1c, which is an average of your blood sugar over three months.
If your glucose level is high, you may feel symptoms like feeling thirsty all the time, urinating more than usual, weight loss, blurry vision or fatigue. Sometimes, people with Type 1 diabetes present, with something called diabetic ketoacidosis, due to not having enough insulin in their body.
This can be a deadly condition that requires hospitalization to help correct the condition.
Low blood sugar can result in sweating, shaking, uncharacteristic behavior, or disorientation. If it goes very low, it may even result in coma and death.
If you notice any of these symptoms, you should notify your doctor.
How do I treat diabetes? Is there a cure?
Unfortunately, diabetes is a chronic illness with no cure. For people with Type 1 diabetes, the only treatment is so far is insulin. For people with Type 2 diabetes, in addition to dietary changes, there are many options that vary from pills to injections.
Some types of bariatric surgery may be helpful in decreasing the amount of people with T2DM need to take. There are many novel technologies being developed to help improve the daily lives of people with diabetes.
Although Type 1 and Type 2 diabetes are invisible to people who do not have it, having a blood sugar that is too high or too low can be very dangerous. But with good control and continual improvement in medication and technology.
