My son has special needs and is post gastrectomy. We noticed that he is waking up in the morning shaky and sweaty. I tested his blood sugars. About 45 minutes after eating his blood sugar is 260 and then drops by 2 hours to around 80. Is this diabetes?

Hi there.
Thank you for the question.
A person with Gastrectomy can actually have this presentation called ' dumping syndrome'- Late dumping syndrome. But having high sugars a short period following a meal is something to check for diabetes. He is having very much normal sugar at 2 hour post meal due to the late dumping syndrome. So you can actually check his fasting glucose, HbA1c and pre-meal sugars before lunch and dinner. This will give clear-cut idea what is happening. Sugar tests you can be done at home on glucometer. HbA1c test will be done in laboratory.
He feeling shaky and sweaty mostly to be due to hypoglycaemia from dumping syndrome.
Wait for reports from your side. Take care.
