Hello there, I understand your concern about your mother s sugar levels. Currently at 290 her sugar levels are definitely high. I assume you took the reading 2 hours after the meal you described which is quite loaded in carbohydrate. However the reading of 290 is not alarmingly high that it needs some urgent remedy. In my opinion try to reduce the carbohydrate content of her meals for now. More of vegetables and salads and proteins but less of carbohydrates. Try to discuss with your diabetologist about bringing her sugars to lower levels. It would have helped me to know your mother s age and if she has any other problems like high blood pressure, any heart related condition or kidney functions. The target sugar levels change with other problems that a patient may have. So for now do not worry, keep her well hydrated and try to include some diet changes. Hope this helps. Take care.
