WHAT IS DIABETES?
The correct name for Diabetes is Diabetes Mellitus. Diabetes Mellitus is a group of metabolic diseases characterized by high blood sugar (glucose) levels that result from defects in insulin secretion, or its action, or both.
INSULIN SECRETIONInsulin secretion in beta cells is triggered by rising blood glucose levels. Starting with the uptake of glucose by the GLUT2 transporter, the glycolytic phosphorylation of glucose causes a rise in the ATP:ADP ratio. This rise inactivates the potassium channel that depolarizes the membrane, causing the calcium channel to open up allowing calcium ions to flow inward. The ensuing rise in levels of calcium leads to the exocytotic release of insulin from their storage granule.
Types of Diabetes
Pre-Diabetes/Impaired Glucose Tolerance
Type 1 Diabetes
Type 2 Diabetes
Gestational Diabetes
PRE-DIABETES/ IMPAIRED GLUCOSE
TOLERANCE
When persons have blood sugar levels that are higher than normal, but not high enough to be classified as diabetes, this is known as pre-diabetes, or impaired glucose tolerance. While people with pre-diabetes usually have no symptoms, it’s almost always present before a person develops type 2 diabetes. However, complications normally associated with diabetes, such as heart disease, can begin to develop even when a person has only pre-diabetic.
Type 1 Diabetes
Type 1 diabetes occurs because the insulin-producing cells of the pancreas (called beta cells) are destroyed by the immune system. People with type 1 diabetes produce no insulin and must use insulin injections to control their blood sugar. Type 1 diabetes most commonly starts in people under the age of 20, but may occur at any age.
Type 2 Diabetes
Type 2 diabetes, is when the body continues to produce insulin, although insulin production by the body may significantly decrease over time. The pancreas produces either not enough insulin, or the body is unable to recognize insulin and use it properly. When there isn't enough insulin or the insulin is not used as it should be, glucose can't get into the body's cells to be used as energy. This glucose then builds up in the blood.
Gestational Diabetes
Hormone changes during pregnancy can affect insulin's ability to work properly and may result in the condition Gestational Diabetes. The condition, called GESTATIONAL DIABETES, occurs in about 4% of all pregnancies.Pregnant women who have an increased risk of developing gestational diabetes are those who are over 25 years old, are above their normal body weight before pregnancy, have a family history of diabetes, or are Hispanic, black, Native American, or Asian.
CAUSES OF DIABETES
Production of defective insulin (which is uncommon),
Pregnancy (gestational diabetes).
The body not responding to the effects of insulin (this is TYPE 2 DIABETES.)
The body's failure to make insulin,( this condition is known as TYPE 1 DIABETES)
The Symptoms of Type 1 Diabetes
INCREASED THIRSTINCREASED HUNGER (ESPECIALLY
AFTER EATING)
DRY MOUTH
FREQUENT URINATION
UNEXPLAINED WEIGHT LOSS (EVEN THOUGH YOU ARE EATING AND FEEL HUNGRY)
FATIGUE (WEAK, TIRED FEELING)
BLURRED VISION
SLOW-HEALING SORES OR CUTS
ITCHING OF THE SKIN (USUALLY IN THE VAGINAL OR GROIN AREA)
YEAST INFECTIONS
RECENT WEIGHT GAIN
NUMBNESS OR TINGLING OF THE HANDS AND FEET
IMPOTENCE OR ERECTILE DYSFUNCTION
THE SYMPTOMS OF TYPE 2 DIABETES
How Is Diabetes Treated?
Diabetes can't be cured, but it can be treated and controlled.
Treating either type 1 diabetes or type 2 diabetes involves medicines, diet, and exercise to control blood sugar level.Getting better control over your blood sugar, cholesterol, and blood pressure levels helps reduce the risk of kidney disease, eye disease, nervous system disease, heart attack, and stroke.
DIABETES PREVENTION
Manage your weight.
Exercise regularly.
Eat a balanced, healthy diet.
Limit takeaway and processed foods.
Limit your alcohol intake.
Quit smoking.
Control your blood pressure
See your doctor for regular check-ups.
Reduce your risk of cardiovascular disease.
