What is diabetes?

Diabetes is a condition resulting from high levels of blood sugar which the body is unable to convert into energy. Type 1 diabetes occurs when there is no insulin, the hormone responsible for controlling blood sugar levels, produced in the pancreas. Type 2 diabetes – the most common form – develops when there is either not enough insulin produced or the body does not use the insulin correctly. If left untreated, diabetes can lead to more serious health problems, therefore early diagnosis is essential to effectively manage the condition. Diabetes can be detected by a blood glucose test, urine glucose test or an HbA1c test.

Symptoms of diabetes

The most common symptoms of both type 1 and type 2 diabetes include fatigue, increased thirst and frequent urination. Diabetes can also cause wounds to heal slower and vision may become blurred.

Who is likely to develop diabetes?

Type 1 diabetes is generally an inherited condition cause by problems with the immune system which prevent the pancreas from producing insulin. Type 2 diabetes most commonly effects people who are obese or overweight, are over 40 and of a particular ethnicity (such as South Asian, Chinese, African Caribbean or Middle Eastern).

Is it possible to prevent diabetes?

Type 1 diabetes cannot be prevented as it is a genetic condition not caused by controllable factors. However, it is possible to reduce the likelihood of developing type 2 diabetes by exercising regularly and eating a healthy, balanced diet low in sugar and fat.

What lifestyle changes will help control / reduce the risk of developing diabetes?

Making improvements to your diet, such as eating a more balanced diet with less sugar and reducing alcohol intake, will help to support the effectiveness of treatment. Stopping smoking, exercising regularly and losing weight if necessary can also help to manage diabetes.

What are the treatment options available?

Diabetes cannot be cured although there are long-term treatment options available. For those suffering from type 1 diabetes, it is necessary to manage this with regular injections of insulin. It is essential to support treatment with positive lifestyle changes to enhance effectiveness.

Type 2 diabetes can often be managed without medication if the recommended lifestyle changes are implemented. If it is necessary to treat type 2 diabetes with medication, Metformin is a tablet used to reduce blood sugar levels.

What side effects are associated with Metformin?

Treatment of type 2 diabetes using Metformin can cause patients to experience nausea, vomiting, diarrhoea and a loss of appetite. It can rarely produce other side effects such as skin rash, liver problems and low levels of vitamin B12.

Which side effects require medical attention?

Stop taking Metformin and seek medical attention if you experience serious side effects such as yellowing of the skin and eyes, numbness or tingling limbs, or liver problems.
