About type 2 diabetes

What is type 2 diabetes?

Type 2 diabetes is a health condition related to how your body deals with sugar. Sugar is broken down in the stomach and enters the blood. A hormone, insulin, is produced to store any extra sugar for later on.

Type 2 diabetes:

  • Is usually caused because the body no longer responds properly to insulin. Glucose (sugar) levels in the blood become too high. This can damage organs such as the heart, kidney, eyes and blood vessels
  • Is often linked to being overweight or inactive
  • Is a lifelong condition that usually gets worse over time. It can be managed at first through better diet and exercise and drugs such as metformin
  • Usually starts later in life, with the chance of getting it becoming much higher when you’re over 40. However, with the rise of obesity in children it is becoming a more common problem in young people
  • Does not always have symptoms at first. If it goes undiagnosed for over 5 years there are higher risks of further problems with the eyes, feet, hands, kidneys and heart. Which is why testing is so important

Am I having symptoms of type 2 diabetes?

The most common, early symptoms of type 2 diabetes are:

  • Wanting to drink more
  • Needing to pee more
  • Being hungry even after eating
  • Dry mouth
  • Losing weight unexpectedly
  • Getting more infections such as thrush or urinary tract infections (UTI)
  • Cuts/wounds take longer to heal
  • Feeling tired
  • Headaches
  • Eyesight problems such as blurred vision
  • Sweet smelling urine

What can cause type 2 diabetes?

Type 2 diabetes can affect anyone but usually affects people are over 40.

Other things that can increase your risk are:

  • Being Black-African, South-Asian or African-Caribbean. Diabetes can start earlier in these groups
  • Having a direct relative (such as a sibling or parent) who has diabetes increases your risk by 6 times
  • Having high blood pressure
  • Being overweight or obese, particularly having high body fat around your waste
  • Smoking and drinking

How do I get tested for treatment?

Early diagnosis is important for preventing damage to the body. You should be tested if you experience any symptoms or you’re one of those who has a higher risk of getting diabetes, and consider testing as part of a general health check.

You can get tested by ordering a home diabetes test kit. At Superdrug Online Doctor, we offer home testing for diabetes. You can order as long as you’re over 18 and you can check to see if you need to think about starting treatment, or if you want to see how well your current treatment is working. The way it works is, you take a pin-prick blood sample to test your blood sugar levels. You send both samples to our lab and your results will be ready, in your account, after 2-3 days, along with advice from a Superdrug online doctor.

Type 2 diabetes can often have no symptoms but still be causing damage to your body. If left undiagnosed it can result in complications that can seriously affect your health. So, it’s important to regularly get tested if you’re at risk.
