Type 2 diabetes may be a chronic condition that affects the way your body metabolizes sugar (glucose) — a crucial source of fuel for your body.
With type 2 diabetes, your body either resists the consequences of insulin — a hormone that regulates the movement of sugar into your cells — or doesn’t produce enough insulin to take care of normal glucose levels.
Type 2 diabetes wont to be referred to as type II diabetes , but today more children are being diagnosed with the disorder, probably thanks to the increase in childhood obesity. there is no cure for type 2 diabetes, but losing weight, eating well and exercising can help manage the disease. If diet and exercise aren’t enough to manage your blood glucose well, you’ll also need diabetes medications or insulin therapy.
Symptoms of Type 2 Diabetes
The symptoms of type 2 diabetes are often so mild that you simply don’t notice them. About 8 million people that have it do not know it. Symptoms include:
- Being very thirsty
- Peeing tons
- Blurry vision
- Being cranky
- Tingling or numbness i your hands or feet
- Fatigue/feeling wiped out
- Wounds that do not heal
- Yeast infections that keep returning
- Weight loss without trying
- Getting more infections
- Dark rashes around your neck or armpits (called acanthosis nigricans) that are often a symbol of insulin resistance
Causes of Type 2 Diabetes
Type 2 diabetes develops when the body becomes immune to insulin or when the pancreas is unable to supply enough insulin. Exactly why this happens is unknown, although genetics and environmental factors, like being overweight and inactive, seem to be contributing factors.
How insulin works
Insulin may be a hormone that comes from the gland situated behind and below the stomach (pancreas).
- The pancreas secretes insulin into the bloodstream.
- The insulin circulates, enabling sugar to enter your cells.
- Insulin lowers the quantity of sugar in your bloodstream.
- As your blood glucose level drops, so does the secretion of insulin from your pancreas.
- The role of glucose
Glucose — a sugar — may be a main source of energy for the cells that structure muscles and other tissues.
Glucose comes from two major sources: food and your liver.
- Sugar is absorbed into the bloodstream, where it enters cells with the assistance of insulin.
Your liver stores and makes glucose.
- When your glucose levels are low, like once you haven’t eaten during a while, the liver breaks down stored glycogen into glucose to stay your glucose level within a traditional range.
- In type 2 diabetes, this process doesn’t work well. rather than getting into your cells, sugar builds up in your bloodstream. As blood glucose levels increase, the insulin-producing beta cells within the pancreas release more insulin, but eventually these cells become impaired and can’t make enough insulin to satisfy the body’s demands.
In the much less common type 1 diabetes, the system mistakenly destroys the beta cells, leaving the body with little to no insulin.
