Hi, I did review your concern. Continuous vomiting in a diabetic is very concerning for either Diabetic ketoacidosis or Nontoxic hyperosmolar coma. I would recommend you to take him to nearby hospital and get his blood and urine evaluated for ketones and lactic acid and also glucose. This may be a fatal situation and earlier you take action better the eventual course is. I hope this helps you. Wish your son healthy life.
