How to Diagnose Vagus Nerve Damage

• Nausea, vomiting, slow digestion, heartburn, low appetite, weight loss, and bloating are all symptoms of gastroparesis.
• Go to the doctor if you experience more than one symptom at once for more than a week. Gastroparesis can cause serious dehydration.
• Get an official diagnosis if necessary. Typically, this will involve an X-ray test or a gastric emptying study.

Gastroparesis Symptoms

Notice if it’s taking longer for food to go through your system. Gastroparesis prevents food from moving through your body at a regular pace. If you notice you’re not going to the bathroom as frequently, it could be a sign that you have gastroparesis.

Pay attention to nausea and vomiting. Nausea and vomiting are common symptoms of gastroparesis. Because your stomach is not emptying as it should, the food is just sitting there, which makes you nauseous. In fact, when you vomit, you may notice the food hasn't been digested at all. This symptom will likely be a daily occurrence.

Notice heartburn. Heartburn is also a common symptom of this disease. Heartburn is a burning sensation in the chest and throat, caused by acid coming back up from your stomach. You'll likely have this symptom regularly.

Check if your appetite is low. This disease can decrease your appetite, as the food you eat isn't being digested properly. That means that new food has nowhere to go, so you won't feel as hungry. In fact, you may feel full after a few bites when you do eat.

Watch for weight loss. Because you won't want to eat as much, you may lose weight. Plus, your stomach isn't digesting the food as it should, so you're not getting the nutrients you need to fuel your body and help you keep weight on.

Look for pain and bloating in your stomach. Because food sits in your stomach longer than it should, you may experience the feeling of being bloated. Similarly, this condition can also give you a stomachache.

Be aware in blood sugar changes if you're a diabetic. This disease is common in type 1 and type 2 diabetics. If you notice your blood sugar readings are more erratic than normal, that could also be a symptom of this issue.

Speaking to Your Doctor

Visit the doctor if you notice a combination of symptoms. Make an appointment to see your doctor if you notice these symptoms together for more than a week, as this disease can have serious complications. It can lead to you becoming dehydrated or malnourished, as your body isn't getting what it needs through digestion.

Make a list of your symptoms. Whenever you go to the doctor, it's a good idea to make a list of your symptoms. Write down the symptoms you've been having and when, so your doctor can get a good idea of what's going on with you. Plus, it will help you remember everything you need to when you get to the doctor's office.

Expect a physical examination and diagnostic tests. The doctor will ask you questions about your medical history, as well as give you a physical exam. They will likely feel your stomach and use a stethoscope to listen to the area. They may also do imaging studies to help figure out what’s causing your symptoms. Bring up any risk factors, which include diabetes and abdominal surgery. Other risk factors include hypothyroidism, infections, nerve disorders, and scleroderma.

Getting Tested

Be ready for an endoscopy or X-rays. The doctor will likely order these tests first to make sure you don't have a stomach blockage. A stomach blockage can cause symptoms that are similar to gastroparesis. For an endoscopy, your doctor will use a tiny camera on a flexible tube. You'll first be given a sedative and likely a throat-numbing spray. The tube will be threaded down the back of your throat and into your esophagus and upper digestive tract. The camera will help your doctor see what's going on more directly than they can with an X-ray. You may also receive a similar test called an esophageal manometry test to measure stomach contractions. In this case, the tube will be inserted through your nose and left in for 15 minutes.

Expect a gastric emptying study. If the doctor doesn't see a blockage in the other tests, they'll likely order this study. This test is a bit more interesting. You'll eat something (such as a an egg sandwich) that has a low dose of radiation. Then the doctor will look at how long it takes you to digest it by using an imaging machine. Typically, you'll get a diagnosis of gastroparesis if half the food is still in your stomach after an hour to an hour and a half.

Ask about an ultrasound. An ultrasound will help the doctor detect if some other issue is causing your symptoms. Particularly, they will look at how well your kidneys and gallbladder are functioning with this test.

Be ready for an electrogastrogram. If the doctor is having a hard time explaining your symptoms, you'll likely have this test done. Basically, it's a way of listening to your stomach for an hour. They'll put electrodes on the outside of your belly. You must have an empty stomach for this test.
