Diabetes Mellitus: Defination, Symptoms & Treatment

Diabetes Mellitus: Symptoms & Treatment

What is diabetes mellitus?

diabetes mellitus

Diabetes mellitus is a disease that prevents your body from properly using the energy from the food you eat. Diabetes occurs in one of the following situations:

The pancreas (an organ behind your stomach) produces little insulin or no insulin at all. (Insulin is a naturally occurring hormone, produced by the beta cells of the pancreas, which helps the body use sugar for energy.)
-Or-

The pancreas makes insulin, but the insulin made does not work as it should. This condition is called insulin resistance.
To better understand diabetes, it helps to know more about how the body uses food for energy (a process called metabolism). Your body is made up of millions of cells.

To make energy, the cells need food in a very simple form. When you eat or drink, much of your food is broken down into a simple sugar called glucose. Glucose provides the energy your body needs for daily activities.

The blood vessels and blood are the highways that transport sugar from where it is either taken in (the stomach) or manufactured (in the liver) to the cells where it is used (muscles) or where it is stored (fat). Sugar cannot go into the cells by itself. The pancreas releases insulin into the blood, which serves as the helper, or the “key,” that lets sugar into the cells for use as energy.

When sugar leaves the bloodstream and enters the cells, the blood sugar level is lowered. Without insulin, or the “key,” sugar cannot get into the body’s cells for use as energy. This causes sugar to rise. Too much sugar in the blood is called “hyperglycemia” (high blood sugar) or diabetes.

What are the types of diabetes?

 

There are two main types of diabetes: Type 1 and Type 2:

Type 1 diabetes occurs because the insulin-producing cells of the pancreas (beta cells) are damaged. In Type 1 diabetes, the pancreas makes little or no insulin, so sugar cannot get into the body’s cells for use as energy. People with Type 1 diabetes must use insulin injections to control their blood glucose. Type 1 is the most common form of diabetes in people who are under age 30, but it can occur at any age. Ten percent of people with diabetes are diagnosed with Type 1.
In Type 2 diabetes, the pancreas makes insulin, but it either doesn’t produce enough, or the insulin does not work properly. Nine out of 10 people with diabetes have Type 2. This type occurs most often in people who are over 40 years old and overweight. Type 2 diabetes may sometimes be controlled with a combination of diet, weight management, and exercise. However, treatment also may include oral glucose-lowering medications (taken by mouth) or insulin injections (shots).
Other types of diabetes might result from pregnancy (gestational diabetes), surgery, use of certain medicines, various illnesses, and other specific causes.

What is gestational diabetes?

Gestational diabetes occurs when there is a high blood glucose level during pregnancy. As pregnancy progresses, the developing baby has a greater need for glucose. Hormone changes during pregnancy also affect the action of insulin, which brings about high blood glucose levels.

Pregnant women who have a greater risk of developing gestational diabetes include those who:

Are over 25 years old
Are above their desired body weight
Have a family history of diabetes
Are Hispanic, African-American, Native American, or Asian-American.
Blood glucose levels usually return to normal after childbirth. However, women who have had gestational diabetes have an increased risk of developing Type 2 diabetes later in life.

What causes diabetes?

The causes of diabetes are not known. The following factors may increase your chance of getting diabetes:

Family history of diabetes or inherited tendency
African-American, Hispanic, Native American, or Asian-American race, Pacific Islander or ethnic background
Being overweight (20 percent or more over your desired body weight)
Physical stress (such as surgery or illness)
Use of certain medications, including steroids and blood pressure medications
Injury to the pancreas (such as infection, tumor, surgery, or accident)
Autoimmune disease
High blood pressure
Abnormal blood cholesterol or triglyceride levels
Age (risk increases with age)
Alcohol (risk increases with years of heavy alcohol use)
Smoking
History of gestational diabetes or delivery of a baby weighing more than 9 pounds (4.1 Kg).
Pregnancy
It is important to note that sugar itself does not cause diabetes. Eating a lot of sugar can lead to tooth decay, but it does not cause diabetes.

What are the symptoms of diabetes?

The symptoms of diabetes include:

Increased thirst
Increased hunger (especially after eating)
Dry mouth
Frequent urination
Unexplained weight loss (even though you are eating and feel hungry)
Weak, tired feeling
Blurred vision
Numbness or tingling in the hands or feet
Slow-healing sores or cuts
Dry and itchy skin (usually in the vaginal or groin area)
Frequent yeast infections

What are the symptoms of low blood sugar?

Most people have symptoms of low blood sugar (hypoglycemia) when their blood sugar is less than 60 mg/dl. (Your health care provider will tell you how to test your blood sugar level.)

When your blood sugar is low, your body gives out signs that you need food. Different people have different symptoms. You will learn to know your symptoms.

Common early symptoms of low blood sugar include the following:

Feeling weak
Feeling dizzy
Feeling hungry
Trembling and feeling shaky
Sweating
Pounding heart
Pale skin
Feeling frightened or anxious
Late symptoms of low blood sugar include:

Feeling confused
Headache
Feeling cranky
Poor coordination
Bad dreams or nightmares
Being unable keep your mind on one subject
Numbness in your mouth and tongue
Passing out
