Hi, your mother is certainly diabetic on has been put on treatment. Treatment of diabetes, confirmed with high levels as she presented shall be taken for a lifetime. A strict follow up of physician s prescription shall be needed for her to maintain her blood sugar levels within normal levels to avert complications such as heart, nervous, eye and kidney complications. It shall be great if you motivate her to take her drugs regularly as prescribes by your family physician, respect the diet prescribed and do her routine control blood tests as prescribed, It could be advisable for you to screen her for hypertension since these diseases usually go together. Stopping treatment now because the blood sugar reduced is not an option to think of. Manipulation, changes in the dosages and drug types in her management most always be changed by her physician. Thanks and stay good, Luchuo, MD.
