[ The necessity of diabetic knowledge ]

Diabetes is not curable, but it is controllable. It is a life time disease, so the patient must know about diabetes and how to treat it. For example, we should know how to maintain our car that we hope to use for a lifetime.
We should know about the oil change, the water levels in radiator etc., and the general knowledge of the car even if we are not the mechanic for the car. It is very useful if we know about the general information for diabetes, even if we are not a Doctor. We must not panic when we face an emergency situation.

One ordinary day, the patient eats more than recommended and then is tested by the Doctor and they increase the dosage of the medication. A few days later, the patient is on a good diet and the sugar level is still going down and they feel the reaction.
If the patient knows about the cause of the low sugar level symptom, they might reduce the dosage of medication. If they do not know then they keep taking the pill in the same dose and continue to feel a bad reaction and increase their problem.

The best method of controlling diabetes is a good diet. The patient should be well trained in this diet skill and use it comfortably. If the diet and exercise do not get control of the diabetes, then discuss with your Doctor about starting a medication.
It is easier to evaluate and understand if the patient has some knowledge about the medication.
