Hello
I have gone through your question and understood your concern.
Gastroparesis is a condition that affects the normal spontaneous movement of the muscles in your stomach.
If you have gastroparesis, your stomach's motility is slowed down or doesn't work at all, preventing your stomach from emptying properly.
Diabetes is a major risc factor that increase the risc of gastroparesis.
Many people with gastroparesis don't have any noticeable signs and symptoms.
But depending to the cause ,the situation can aggravate and gastroparesis can produce lots of symptoms like nausea,vomiting,a feeling of fullness after eating just a few bites,
acid reflux,
lack of appetite,changes in blood sugar levels ,
weight loss and
malnutrition.
My answer for you is:Yes,there are two grades of gastroparesis.
Grade 1, or mild gastroparesis, is characterized by symptoms that come and go and can easily be controlled by dietary modification and by avoiding medications that slow gastric emptying.
Grade 2, is characterized by moderately severe symptoms.
Hope i have clarified all your doubts.
If you have other questions,feel free and ask.
Regards.
