diabetes mellitus itself adversely affects patients' psychological states by changes in glusoce metabolism,blood and CSF osmolality ,needs for discipline and compliance,fear of long term complications and threat of hypoglycemic attacks and the possibility of dehydration and coma.
on the other hand,fasting during ramadhan has a tranquilizing effect on the mind,producing inner peace and decrease in anger and hostility.
fasting muslims realize that manifestations of anger may take away the blessings of fasting or even nullify them.
diabetics know that stress increases the blood glucose by increasing the catecholamine level and any tool to lower the stress ; ie.,biofeedback or relaxation improves diabetic control.
thus,Islamic fasting during Ramadhan should have a potentially beneficial effect with regard to diabetic control.
