Diabetes is a long-term health condition where the body cannot properly regulate your blood sugar (glucose) levels. Glucose comes from the food you eat (primarily from carbohydrates and foods with sugar), which is how your body powers your cells. The hormone insulin plays a vital role in this process by allowing glucose to enter your cells so that they can convert it to energy.
In most people, insulin is made in the pancreas and released when eating. However, people who have diabetes either fail to produce enough insulin for their cells to process glucose or their cells don’t respond to insulin properly. This malfunction can cause severe problems for the body, and people with diabetes must carefully manage their condition.
There are two types of diabetes, called type 1 diabetes and type 2 diabetes. Type 2 diabetes is far more common, and over 90% of people who have diabetes in the UK have type 2 diabetes. This resource will examine both types of diabetes, what causes these conditions, their symptoms, and treatments.
Type 1 diabetes is an autoimmune disorder, which means the body's immune system mistakenly attacks and destroys the insulin-producing cells in your pancreas. The destruction of these cells means the body can no longer produce the insulin it needs to regulate blood sugar levels, leading to increased glucose in the bloodstream.
The onset of Type 1 diabetes can be sudden, and people often have pronounced symptoms. These include:
Managing Type 1 diabetes involves a combination of lifestyle adjustments and medical interventions:
Type 2 diabetes is caused by insulin resistance, where the body's cells do not respond effectively to insulin. Unlike Type 1 diabetes, which is an autoimmune condition, Type 2 is more commonly associated with lifestyle factors and can often be managed with lifestyle changes and monitoring.
The symptoms of Type 2 diabetes can be more subtle and develop gradually, including:
Treatment for Type 2 diabetes typically involves:
For many, with lifestyle changes, such as losing weight and managing diet, it is possible to reduce blood sugar levels to normal, so the condition is in remission. Being in remission means it is possible to live without the need for medication or daily monitoring so long as the lifestyle changes are maintained.
If you think you are suffering from any of these symptoms, seeing a doctor as soon as possible is crucial. Untreated diabetes can cause serious health problems. You can register online here if you live in London and have not yet registered with a GP.
