Type 2 diabetes and medication


  1. Myth: People with Type 2 diabetes need insulin when they don’t look after themselves

Overtime the pancreas produces less insulin or the insulin just isn’t working properly in the body causing the blood glucose to rise. When this happens insulin injections are prescribed to help lower the blood glucose and improve your blood glucose levels. Insulin can also be prescribed when diagnosed with certain medical conditions or prescribed medication that is known to increase the blood glucose, for example taking steroids to treat an asthma attack.


  1. Myth: Insulin therapy makes you gain weight

Insulin per se does not cause weight gain it is the effect it has on the body. Insulin helps glucose enter the cells for energy, when this cannot happen the blood glucose levels rise and the kidneys remove the extra glucose into the urine. Glucose present in the urine means the urine contains calories, so you are flushing away both calories and fluid hence the weight loss. When insulin therapy is started this process is corrected, you begin to retain the calories and fluid and your weight increases. If you are concerned about your weight speak with your healthcare team, as you may need to make some dietary changes.


  1. Myth: Herbal supplements help Type 2 diabetes

Healthy eating, physical activity and maintaining a healthy weight are the first steps of managing diabetes. When these lifestyle measures are not enough to maintain your blood glucose levels medication is required. Along with these lifestyle measure and medication people with diabetes have tried herbs and supplements to improve their diabetes. However, there is currently only limited evidence of any benefit. Your healthcare team can help you decide which medications will work best for you.
