I am 81 years old, eat a healthy diet, exercise, and walk or run briskly every day.  Just after I took the Pfizer COVID-19 vaccines in March of this year (3/10/2021 and 3/31/2021) I started having the primary symptoms for gastroparesis, particularly the bloated feeling you immediately feel when starting to eat because food stays in your stomach for longer than it should. Before this I could eat as much as I want and never had this feeling. I hoped it would go away but it has not.  How could a condition as radical as this happen all of a sudden in such a short amount of time?  Diabetes is the most common known cause of gastroparesis. It can damage nerves including the vagus nerve which regulates your digestive system and certain cells in your stomach. But I do not have diabetes according to two blood tests I took after getting the COVID-19 vaccine. And to my knowledge I haven?t had possible causes of gastroparesis such as: Injury to my vagus nerve from surgery A lack of thyroid hormone (hypothyroidism) Viral stomach infections (gastroenteritis) Medications such as narcotics and some antidepressants Parkinson's disease Multiple sclerosis Rare conditions such as amyloidosis (deposits of protein fibers in tissues and organs) and scleroderma (a connective tissue disorder that affects your skin, blood vessels, skeletal muscles, and internal organs)  However, gastroparesis is a common symptom that may occur with peripheral neuropathy. So could the Pfizer COVID-19 vaccine produce a side effect similar to Type A Diabetes, but in this case the insulin receptor protein is only damaged on a specific type of cells, like nerve cells? Or could the peripheral neuropathy that produces gastroparesis be due to something else? Have conditions such as these been investigated?  Because my bloating feeling developed slowly it?s hard to put an exact date and time when the adverse event started. I wasn?t aware of any side effects when taking the two vaccinations and I didn?t notice the gastroparesis symptoms until about a month later. But that does not mean the symptoms were not there. My side effects could have developed slowly (e.g., slow damage to the vagus nerve) and my time and date that the adverse event started [04/2021, 12:00 PM] was an estimate. I got that from my first observation around 5/01/2021 when I was bloated without eating soon beforehand and worked backwards based on how fast my stomach condition was getting worse. But I may have even had the side effect after the first vaccination.  On 06/18/2021 I reported my condition to my doctor?s PA who said someone should test my GI tract. 09/20/2012 is the earliest appointment I could get with a gastroenterologist.  In the same vein my body weight has dropped during the same time period. Prior to this period my weight was 127 to 129 pounds depending on when I measured it. Now it is 121-123 pounds.  Although probably not related, around the same time as having gastroparesis symptoms my eyesight changed radically. For about 8 years before I got the vaccine my eyeglass distance prescription was right eye 2.75, left eye 2.25. But my vision is now better when I turn my eyeglasses upside down and reverse the magnification for each eye. The same holds true when I do the same for my reading glasses.  My eyes were examined on 5/25/2021 and had no physical problems. I am getting an eyeglass exam later in the year.  The COVID-19 Vaccine was developed in just one year. Have enough side effects been investigated, including the out-of-the ordinary ones?  Items 15, 16 and 17: The vaccines were given to many people by the clinic. Ask the clinic for the Lot number.  Item 21: I have seen that gastroparesis cannot be cured.
