I am a 25 year old female who has recently been diagnosed with gastroparesis as a result of the x-ray 'boiled egg on wheat toast' test. However, I am 'too young' for the disease, am not diabetic, have not had any major viral infections, have had multiple negative ANAs (I also suffer from a butterfly rash, joint pain, and frequent headaches), and in all other ways 'shouldn't' have gastroparesis.
What are the symptomatic differences between gastroparesis and gastric cancer? By most lists I've been able to find on the web, the 'difference' seems to be that gastroparesis is common in diabetics and patients with an auto-immune or neurological condition. I know gastric cancer is extremely rare in the US, and my GI is hesitant to do an upper endoscopy given my history with anasthesia (20 minutes under for most people becomes 4 days for me.)
My symptoms include the vomiting of undigested food, premature fullness, severe pain under my left ribcage after eating (with dizziness and nausea when I haven't eaten), my blood sugar ranges from 40 to 180, seemingly independent of when I've last eaten (12 hour fasting blood sugar was 90, blood sugar 2 hours after lunch was 50), heartburn, gas, general discomfort and nausea, and skinniness. (I'm 5'6 and have never gotten above 105 pounds).
