Nausea Specialist

You might get a little queasy on an airplane ride, or after eating something unfamiliar, but nausea isn’t something that should be a part of your daily life. At Los Angeles Gastroenterology Clinic in Santa Monica, California, gastroenterologist S. Radi Shamsi, MD, uses the most modern equipment to diagnose causes of nausea. You can feel confident that you have a doctor on your side who is dedicated to diagnosing your nausea, and getting you the treatment you need.

Nausea Q&A

When should I be concerned about nausea?

It’s normal to have occasional nausea, like if you’re sensitive to long car rides, or eat something unsettling. But if your nausea is frequent or is associated with other issues, it’s time to visit Dr. Shamsi. Get in right away if you:

  • Have nausea for more than a few days
  • Are dehydrated
  • Also have diarrhea or vomiting
  • See blood in your vomit
  • Have a bad headache
  • Have a stiff neck
  • Feel confused or lethargic
  • Notice a rapid heartbeat
  • Breathe heavily
  • Have severe abdominal pain

What might be causing my nausea?

Nausea is a symptom of so many different diseases and health conditions, so it might take some trial and error to get to the root of your problem. But rest assured, with Dr. Shamsi, you’re in expert, caring hands. He can determine if your nausea is caused by:

  • Gallbladder disease
  • Food poisoning or allergies
  • Bacterial or viral infections
  • Motion sickness
  • Overeating
  • Stomach ulcers
  • Delayed stomach emptying
  • Kidney problems
  • Environmental issues
  • Undiagnosed pain

How is the cause of nausea diagnosed?

Dr. Shamsi will need to get a full medical history from you, so it can be helpful to keep a journal for a few days before going in for your appointment. Make a note if something in your diet makes your nausea worse — or better — or if your nausea comes on during a certain time of day. The more details you can provide, the more efficient it’ll be for him to thoroughly diagnose you.

Because it’s not normal to have long bouts of nausea, Dr. Shamsi will want to find out exactly what’s causing it and treat the problem appropriately. He may need to get a look inside your gastrointestinal tract using specialized imaging.

Traditional X-rays and CT scans only show so much of what’s going on inside of you, often requiring you to need a more thorough type of imaging. Dr. Shamsi sometimes uses nuclear medicine tests to help diagnose digestive issues. This type of testing uses a small amount of radioactive material to help highlight tissues and organs. It allows Dr. Shamsi to get clear images of issues that might be causing your nausea, including gastric motility (gastroparesis), gallbladder motility (biliary dyskinesia), or tumors.
