Once you are diagnosed the rest is down to you. The doctors will simply monitor your condition and if it gets worse will advise tablets or insulin. Most diabetics keep their diabetes under control with good diet and regular eating (every 4 hours). You can research this yourself on the internet. You can also buy blood sugar monitors from chemists. If you are diabetic you should also have regular eye examinations and also clean and treat cuts immediately to prevent infection. If you have any other medical treatment ie tooth extracted you should advise them you are diabetic.
