Types Of Diabetes

In medical parlance, this disease is known as "diabetes mellitus" - diabetes from the Greek word for siphon, to illustrate the excessive thirst and urination, which is characteristic of this condition, and mellitus from the Latin word for honey - as urine of a diabetic person contains sugar and is sweet.

Commonly, this disease is called diabetes.

There are many types of diabetes, but the three most common are:

« Type 1 diabetes

« Type 2 diabetes

« Gestational diabetes

1. Type 1 diabetes (also known as insulin dependent diabetes):

This is an autoimmune disease where the body's own immune system attacks and destroys the insulin-producing beta cells in the pancreas. The pancreas then produces little or no insulin. It can appear at any age, although mostly under 30 (very often in childhood or during teens), and is caused by environmental factors such as viruses, diet or people genetically predisposed. This type of diabetes, is also known as juvenile-onset diabetes.

It is not really known what causes type 1 diabetes and it is not caused by eating too much sugar or sweets.

Symptoms of type 1 diabetes usually develop over a short period, although beta cell destruction can begin much earlier. Common symptoms include increased thirst and urination, constant hunger, weight loss, blurred vision, and extreme weakness. If not timely diagnosed and treated with insulin, a person with type 1 diabetes can go into life-threatening diabetic coma, also known as diabetic ketoacidosis.

2. Type 2 diabetes (non-insulin dependent diabetes):

This is the most common form of diabetes, affecting 85-90% of all diagnosed people. It is also known as late-onset diabetes, and is characterised by insulin resistance and relative insulin deficiency.

Type 2 diabetes is genetic in origin, but other factors such as excess weight, sedentary lifestyle, high blood pressure, ethnicity and faulty diet are its major risk factors. Symptoms may not show up for many years, and by the time they crop up, considerable harm may have been done to the body.

In this condition, the pancreas is usually producing enough insulin, but for reasons unknown, the body cannot use the insulin effectively - termed as insulin resistance. As a result, glucose builds up in the blood and the body cannot make proficient use of its main source of energy.

The symptoms of type 2 diabetes develop gradually. Symptoms include weakness, nausea, frequent urination, excess thirst, weight loss, blurred vision, frequent infections, and slow healing of wounds. Some people may show no symptoms.

Type 2 diabetes is a progressive, lifetime condition; and over time, it may be difficult to keep the blood glucose level in the target range. However, good diabetes care and management can prevent or delay the onset of complications.

One can do this by:

« Eating healthy meals and snacks

« Following regular physical activity

« Taking diabetes medications (including insulin), if prescribed.

3. Gestational diabetes:

Gestational diabetes develops only during pregnancy. In most cases, all diabetic symptoms disappear following delivery. Women who have had gestational diabetes have a 20 to 50 % chance of developing type 2 diabetes within 5 to 10 years, especially if they were overweight before the pregnancy.

Gestational diabetes is not caused by a lack of insulin, but by blocking effects of other hormones (estrogen, cortisol, and human placental lactogen) on the insulin that is produced, a condition referred to as insulin resistance. Normally, the pancreas is able to make additional insulin to overcome insulin resistance. However, when the production of insulin is not enough to overcome the effect of the placental hormones, gestational diabetes results.

Carbohydrate intolerance is diagnosed during pregnancy through an oral glucose tolerance test (OGTT). While the carbohydrate intolerance usually returns to normal level after delivery, the mother has a significant risk of developing permanent diabetes later on; while the baby is more likely to develop obesity and impaired glucose tolerance and/or diabetes later in life.

Risk factors include a family history of diabetes, increasing maternal age, obesity and being a member of a ethnic group with a high risk of developing type 2 diabetes.

The complications of gestational diabetes are usually manageable and preventable. The key to prevention is careful control of blood sugar levels as soon as the diagnosis of gestational diabetes is made.

Other types of diabetes -

4. Diabetes insipidus:

Diabetes insipidus is an uncommon condition, that occurs when the kidneys are unable to conserve water as they perform their function of filtering blood. The anti-diuretic hormone (ADH, also called vasopressin) controls the amount of water conserved. Diseases of the kidney (for example, polycystic kidney disease) and the effects of certain drugs may also cause nephrogenic diabetes insipidus.

The common symptoms are excessive ********* and extreme thirst.

5. Syndrome X:

Syndrome X, also known as the "metabolic syndrome" or "Insulin Resistance Syndrome", is a condition that is linked to an increased risk of diabetes and heart disease.

It is characterised by abdominal obesity, elevated levels of triglycerides, low levels of HDL (good) cholesterol, high blood pressure and high blood sugar levels. Other symptoms include smoking, high fat and calorie diet, pre-diabetes or Type 2 diabetes, polycystic ovary syndrome.

This is more common in older people than in younger people. In addition, women were more likely to have the syndrome than men.

Different Type of Diabetes

There are many types of diabetes, but the three most common are:

1. Type 1

2. Type 2

3. Gestational

These three types of Diabetes are same with some differences, everyone with diabetes has one thing in common and that is little or no ability to move glucose out of the blood into the cells, where it is converted into body's primary fuel. We all have glucose in our blood, whether or not we have diabetes. Main source for glucose is food which we eat. When we eat, the digestive system breaks down food into glucose, which is absorbed into the blood in the small intestine.

People who don't suffer from diabetes depend on insulin, a hormone made in the pancreas, to move glucose from the blood into the body's billions of cells. But people who suffer from diabetes either don't produce insulin or can't efficiently use the insulin produced in their body. Without insulin, glucose can’t move into blood cells. Scientists don't know the exact reason behind cause’s diabetes, but it seems to be a result from a combination of genetics and environmental factors, including viral infections, poor diet, and sedentary lifestyle. Till now, diabetes has no solution, but the good news is that the disease can be managed and treated. People with diabetes can live fulfilling, healthy lives.

Type 1

Diabetics with type 1 diabetes, also known as insulin-dependent diabetes mellitus or IDDM don't produce insulin and require regular supply of insulin to keep their blood glucose levels normal. Type 1 diabetes was known as juvenile-onset diabetes, but that name has been changed because type 1 diabetes also strikes young and older adults alike.

Risk factors



A family history of the diabetes increases risk for next generations.

Diabetes can happen in people of every society, but it's most common among whites.

Half of type 1 diabetics are under the age of 20. Being age 20 or younger increases the risk.



What causes it?

Most of the children, whose parents are diabetics, do not suffer from this disease, but scientists still believe that heredity plays a big role in Type 1 diabetes because it tends to run in families.

Researchers have researched on several genes that appear to increase risk of type 1 diabetes. But they haven't got a single gene that causes diabetes.

Type 1 diabetes has many hallmarks of an auto-immune condition. In auto-immune diseases, the immune system, this protects from disease by killing invading germs. In the case of type 1 diabetes, the immune system kills the cells in the pancreas that produces insulin.

Type 1 diabetes often occurs shortly after a viral infection, and doctors sometimes notice a sharp jump in type 1 diabetes diagnoses after viral epidemics.

Type 2

Approximately 95 % of diabetics suffer with type 2 diabetes which is also known as non-insulin-dependent diabetes mellitus or NIDDM. Type 2 Diabetics produces insulin, but the cells in their bodies are "insulin resistant" they can't respond properly to the hormone, so glucose is accumulated in their blood. Some people with type 2 diabetes inject insulin, but mostly can control the disease through a combination of weight loss, exercise, a prescription oral diabetes medication, and tight control.

Risk factors



Similar to Type 1, Type 2 disease also runs in families and increase the risk for upcoming generations.

Most of the diagnosed people with type 2 are above of age 30 or older. Half of all new cases lie between age 55 and older.

In comparison of whites and Asians, type 2 diabetes is more commonly found among Native Americans, African-Americans, Latinos, and Hispanics.

Insulin resistance results in increment of weight and decrement of physical activities. Most of the people suffering from type 2 diabetes have sedentary lifestyles and are obese; there weight increases at least 20 percent more than the recommended weight according to their height and build.

Less exercise, especially for those who are overweight, increases the risk for diabetes.

If a female developed gestational diabetes during pregnancy, she is at a higher risk of type 2 diabetes later.

Females who have given birth to babies weighing 9 pounds or more are at an increased risk of Type 2 Diabetes.



What causes it?



Scientists are not sure, but type 2 diabetes, like type 1 diabetes, flows from families to families, which shows some genetic connection. In fact, a genetic link in Type2 diabetes seems even stronger in comparison with type 1. Scientists have not yet found a single gene that causes the disease, but they are still in search for errors in several that may contribute to the disease. Researchers also have a doubt on genetic susceptibility to obesity.

Obesity is the only single most important cause of type 2 diabetes. There are different definitions for obesity, but in general, Obesity occurs if a person’s weight is at least 20 percent more than what's recommended according to their height and build. 75% of people with type 2 diabetes have problem of being overweight. That's why type 2 diabetes is usually linked with diet and exercise.

Less weight and good muscles helps the body use insulin more effectively. This is very important to know how much weight we should carry. People whose weight is above their hips have a greater risk of developing type 2 diabetes than those who carry it on their hips.

Age also plays an important role in type 2 diabetes. Most of the newly diagnosed are of age 55 and above, and around 11 percent of Americans ages 65 to 74 suffers from type 2 diabetes. However, it is not sure if age is a cause of type 2 diabetes or it is simply a reflection of the fact that people tend to gain weight and become less physically active as they grow older.

Gestational

Gestational diabetes affects only to pregnant ladies without any previous history of diabetes. Nearly 137,000 U.S. females develop gestational diabetes each year.

Typically, gestational diabetes is cleared up on its own after female’s delivery. But research shows that about 40% of females with gestational diabetes face type 2 diabetes within 15 years. All pregnant ladies should be tested for gestational diabetes between their 24th and 28th weeks of pregnancy.

Gestational diabetes and insulin resistance can be prevented by keeping a healthy weight, having healthy food and with the help of regular exercise.

Risk factors



Diabetes problem flows from generation to generation.

Increase in weight, increases insulin resistance.

Native Americans, African-Americans, and people of Hispanic or Latino descent are at increased risk. Whites and Asians have a lower risk.



What causes it?

Hormones may play an important role. Pregnant ladies produce various hormones important for their baby's growth. However, these hormones may interfere with the mother's body's ability to properly use insulin, causing insulin resistance.

Every pregnant lady has some degree of insulin resistance. But if this resistance becomes full-blown gestational diabetes, it usually appears around the 24th week of pregnancy. That's why all pregnant ladies should be screened for gestational diabetes at that time.
