Brief Answer:
Not to give solid food as he had recent vomiting episode

Detailed Answer:
Good day,

Noted your concern. Type 1 diabetes and Grave's disease are auto immune disorders. So your son is likely to have poly glandular auto immune disease.

In Grave's disease, the insulin metabolism is faster and diabetes gets uncontrolled.

If he had a severe vomiting episode, it is better not to feed him solid food now.
Best to give him some clear fluids first and wait. If he is not vomiting, then you may give liquids like soups. If he is tolerating that, then give solid food.

However, if he is drowsy or sugars persistently high, if dehydrated or if there is continuous vomiting, please take him to hospital. These may be signs of diabetic ketosis ( DKA).
