Dear Aaru ,
A good question indeed.First,the patient must know what is sugar.when the food you eat is digested ,it must be converted into glucose and absorbed fully into the blood stream - when this does not happen , the excess glucose remains unabsorbed leading to diabetic.As such ,we must basically avoid overeating - we must eat only when it is needed.Especially once you are confirmed to be a diabetic , you must have total control over your intake.If you have control , you can even forego medicines and think of taking sweets to a limited extent.
next is , every diabetic must do physical exercise necessarily.Depending on the age , we must consult a good physician. In any case , it is advisable to go for brisk walking for 35 min.in the early morning ,without getting diverted - no deviation is allowed.In fact ,it is advisable that we sweat at the end of walking.We must drink lot of water.There must be discipline in food intake - both in quantity and quality.You can eat fresh vegetables , greens , fruits ., etc., Give up rice.Eat 3/4 idlies at 08-09a.m.,;4 chappathies with vegetables and some pieces of raw vegetable.Have a cup of tea at 5.00 p.m., with 2 biscuits. then take 3/4 chappathies/idlies or 2/3 doasa at 08.00 p.m.,Take half a cup of diluted milk.There must be a gap of min.2 hours from last intake and bed time.In acse you feel hungry , there is no harm in taking some pieces of apple or orange in between -never allow yourself to feel hungry - at the same time, donot overeat.
Apart from this , keep your sugar level always under control - get it checked once in a month.Also test your blood for the average sugar level once in 4 months (HbAlc) - this must be 6-8.
I suffered for 5 years and could not control sugar levels, as i didnot exercise control over food.But now for the past 6 months , my HbAlc is well within 6/7 only.It is not difficult at all to control your blood sugar levels.Also , last but not the least , you must avoid tension.
