Chronic Nausea and Vomiting in Northern Virginia

← Patient Education

Chronic nausea and vomiting is one of the more draining symptoms a person can live with, and in Northern Virginia, as everywhere, it often goes on longer than it should before anyone looks for the cause. A stomach bug or a bad meal passes in a day or two. Nausea that is still there a month later, or vomiting that keeps returning in waves, is a different situation with a different set of possible explanations. A 2024 review in American Family Physician, the journal of the American Academy of Family Physicians, defines acute nausea and vomiting as lasting up to 7 days and chronic nausea and vomiting as lasting 4 weeks or longer, and notes that the chronic form has a broad list of possible causes, inside and outside the digestive tract. This guide explains what that list includes, the warning signs that need prompt or emergency care, the patterns that point toward a particular cause, and what an evaluation with a gastroenterologist involves.

This article is general education, not medical advice. Ongoing nausea or vomiting should be evaluated by a physician who can consider your full history.

What counts as chronic nausea and vomiting

Nausea is the unpleasant sense that vomiting might happen. Vomiting is the forceful emptying of the stomach through the mouth. Both are common, and in the short term they are usually the body reacting to an infection, a food, motion, or a medication. The same AAFP review states that acute nausea and vomiting without alarm symptoms are typically treated for comfort without an extensive workup, because they usually resolve on their own.

The chronic form is defined by time: symptoms that persist for 4 weeks or longer. That threshold matters because it changes the likely causes. Infections become less likely. Slower processes, such as a stomach that empties too slowly, a medication taken every day, an ulcer, or a hormonal or metabolic problem, become more likely. The symptoms do not have to be constant to count. Nausea most mornings for six weeks is chronic. So is vomiting that arrives in severe episodes every few weeks with normal days in between.

A physician will also want to know whether what is happening is truly vomiting. The AAFP review separates vomiting from two things that are easily confused with it. Regurgitation is stomach contents moving back up into the esophagus or mouth without the heaving muscle contractions of vomiting, as can happen with reflux or a narrowing of the esophagus. Rumination is an effortless return of recently eaten food into the mouth, where it is often rechewed and swallowed. Each has a different evaluation, so describing the experience accurately is a useful first step.

Red flags: when chronic nausea and vomiting needs prompt care

Most ongoing nausea can be evaluated in an office visit. Some situations should not wait for one. The National Library of Medicine's MedlinePlus guide to nausea and vomiting in adults advises calling 911 or going to an emergency room for vomit that contains blood or dark material that looks like coffee grounds, or when poisoning is a possibility. It advises contacting a provider right away for:

• Vomiting that has lasted longer than 24 hours
• Being unable to keep any fluids down for 12 hours or more
• Vomiting 3 or more times in one day
• Severe stomach or belly pain
• Headache or a stiff neck
• Not urinating for 8 hours or more

Signs of dehydration, including a dry mouth, increased thirst, sunken eyes, dark yellow urine, or urinating less often, are a reason for prompt care on their own. For longer-running symptoms, the AAFP review lists alarm features that call for a more thorough workup rather than simple symptom relief. They include age over 55, unintended weight loss of more than 5 percent, difficulty swallowing that is getting worse, feeling full after only a few bites, a change in bowel habits, persistent vomiting, severe abdominal pain, vomit that smells like stool, yellowing of the skin or eyes, any sign of bleeding in the digestive tract, confusion, or new weakness or numbness. Chest pain with nausea deserves particular caution, because a heart attack can cause nausea and the AAFP lists it among the possible causes. New chest pain is a reason to seek emergency care, not to assume the problem is digestive.

Common digestive causes of chronic nausea and vomiting

The digestive tract is the most common source of these symptoms. The AAFP review notes that sudden symptoms most often come from an infection, an inflammatory condition, or a blockage, while motility disorders tend to come on gradually and persist. The conditions a gastroenterologist commonly considers include:

• Gastroparesis. A stomach that empties too slowly without any physical blockage. Nausea, early fullness, bloating, and vomiting of food eaten hours earlier are typical. Diabetes is one of its most recognized causes. Our guide to gastroparesis in Northern Virginia covers the condition and the gastric emptying study that confirms it.
• Reflux and dyspepsia. GERD and functional dyspepsia, a recurring upper-abdominal discomfort without a visible cause, can both produce ongoing nausea. The AAFP notes that chronic nausea related to reflux or dyspepsia is often first treated with an acid-reducing medication, with further evaluation if symptoms continue.
• Gastritis and peptic ulcers. Inflammation of the stomach lining and open sores in the stomach or first part of the small intestine, frequently linked to H. pylori infection or regular use of anti-inflammatory pain relievers. See our pages on gastritis and peptic ulcers and H. pylori.
• Gallbladder and pancreas. Gallstones can cause episodes of upper-right abdominal pain with nausea, often after a fatty meal, and pancreatitis typically causes upper-abdominal pain that can spread to the back, with nausea and vomiting.
• Irritable bowel syndrome. The AAFP lists IBS among the common gastrointestinal causes, and nausea can accompany the cramping and altered bowel habits that define it. Our IBS guide explains the diagnosis.
• Alpha-gal syndrome. An allergy to red meat and other mammal products, linked in the United States to lone star tick bites, that can cause nausea, vomiting, and abdominal pain two to six hours after a meal, sometimes with no rash. See our page on alpha-gal syndrome.
• Blockage. A narrowing where the stomach empties into the small intestine, called gastric outlet obstruction, or a blockage further down the intestine can cause vomiting, sometimes of partly digested food or of green bile. Blockages are less common but important to rule out, and a sudden blockage is an emergency.

These conditions overlap heavily in how they feel, which is the main reason ongoing symptoms are better evaluated than self-diagnosed. The same week of symptoms can come from a slow stomach, an ulcer, or a medication, and each calls for a different plan. For a broader look at how abdominal symptoms are sorted, see our guide to chronic abdominal pain.

Medications and substances that cause ongoing nausea

A medication is one of the first things a physician looks for, because it is common and often correctable. The AAFP review notes that medications usually cause nausea within days of starting them, and names antibiotics, chemotherapy, nonsteroidal anti-inflammatory drugs such as ibuprofen and naproxen, opioid pain medications, metformin, estrogen-containing medications including oral contraceptives, and GLP-1 receptor agonists. That last group includes the injectable medications now widely prescribed for type 2 diabetes and weight management, and MedlinePlus lists them by name among the common causes of nausea and vomiting. Alcohol, both heavy use and withdrawal, belongs on the same list.

If you suspect a medication, do not stop a prescribed drug on your own. Some medications are dangerous to stop abruptly, and others can be adjusted, changed in dose, or timed differently. Bring a complete list of everything you take, including supplements and over-the-counter products, with doses and start dates, to any appointment about ongoing nausea. A medication started shortly before the symptoms began is one of the most useful clues a physician can have.

Cannabis is a separate and increasingly common cause, covered in its own section below.

Causes of chronic nausea and vomiting outside the digestive tract

Nausea and vomiting are controlled by the brain, which receives signals from the gut, the inner ear, the bloodstream, and emotional centers. That is why many causes of ongoing nausea are not digestive at all. The AAFP review groups them into several categories:

• Pregnancy. The most common hormonal cause. The review notes that up to 75 percent of pregnancies involve recurrent nausea and vomiting, and that hyperemesis gravidarum, severe persistent vomiting in pregnancy, occurs in 0.5 to 1 percent. A pregnancy test is a routine part of the evaluation for anyone who could be pregnant, and pregnancy-related symptoms are managed with an obstetric provider. Our page on digestive problems in pregnancy covers nausea in pregnancy and the signs that need a prompt call.
• Metabolic and hormonal conditions. Kidney disease, electrolyte imbalances such as high calcium or low sodium, thyroid, parathyroid, and adrenal disorders, and diabetic ketoacidosis, a diabetes emergency that can cause vomiting with confusion and a fruity breath odor.
• Neurologic and inner-ear causes. Migraine, motion sickness, vertigo disorders such as Meniere disease and benign positional vertigo, and, less commonly, conditions that raise pressure inside the skull. Vomiting with a severe headache, a stiff neck, or changes in vision or speech needs emergency care.
• Anxiety and depression. Both can cause ongoing nausea, and the review notes that habitual vomiting after meals can be associated with depression. This is a real physiological effect, not an imagined symptom, and it is treatable.
• Eating disorders. The review notes that vomiting related to an eating disorder is often not reported, and that affected patients may need care for its complications. A physician asks about this respectfully and without judgment.

A gastroenterologist evaluates chronic nausea and vomiting with all of these in mind, and coordinates with primary care, obstetrics, neurology, or behavioral health when the cause turns out to sit in one of those areas.

Clues in the pattern of symptoms

How and when symptoms happen often narrows the possibilities before any test is ordered. The AAFP review summarizes several patterns that point toward particular causes:

• Vomiting more than an hour after meals, or of partly digested food. Suggests the stomach is not emptying normally, from gastroparesis or a blockage at the stomach outlet.
• Undigested food coming back up. Suggests a problem in the esophagus, such as a narrowing or a motility disorder, which is regurgitation rather than true vomiting. Our guide to difficulty swallowing covers these conditions.
• Vomiting before breakfast. Can be associated with pregnancy, alcohol use, kidney failure, or increased pressure in the skull.
• Green or bile-stained vomit, or vomit with a stool-like odor. Suggests an intestinal blockage and needs prompt evaluation.
• Symptoms that came on gradually. Point toward reflux, gastroparesis, a metabolic cause, or pregnancy.
• Vomiting during or soon after meals. Can be associated with an eating disorder.
• Severe episodes separated by weeks of feeling well. Suggest cyclic vomiting syndrome, described below.

No single pattern makes a diagnosis. Together with your history and an examination, though, the pattern tells a physician where to look first, which is why a written symptom record is worth bringing to the appointment.

Cyclic vomiting syndrome and cannabinoid hyperemesis syndrome

Some people do not have daily symptoms at all. Instead they have sudden, severe attacks of vomiting that last hours to days, followed by weeks or months of feeling normal. The National Institute of Diabetes and Digestive and Kidney Diseases describes this as cyclic vomiting syndrome, a functional gastrointestinal disorder in which episodes can be severe enough to require emergency care, and which can continue for years. NIDDK notes that experts believe it may be as common in adults as in children, and that migraine, a family history of migraine, a tendency toward motion sickness, and long-term marijuana use all raise the likelihood of having it.

NIDDK describes four phases. A prodrome of intense sweating, nausea, and sometimes abdominal pain signals that an episode is coming. The vomiting phase can involve vomiting several times an hour. A recovery phase follows as appetite and energy return, and then a well phase with no symptoms. Episodes in the same person tend to start at the same time of day, often early morning, and to last about the same length of time. For adults, NIDDK notes that physicians often suspect the syndrome when there have been three or more separate episodes in the past year and two in the past six months, at least a week apart, each lasting less than a week, with no other condition to explain them. Common triggers include stress, lack of sleep, infections, fasting, and menstrual periods.

Cannabis has become a central part of this conversation. In a 2019 population survey published in Clinical Gastroenterology and Hepatology, about 3 percent of U.S. adults met symptom criteria for one of the functional nausea and vomiting disorders, and 2 percent met criteria for cyclic vomiting syndrome, a higher rate than in Canada or the United Kingdom. Cannabinoid hyperemesis syndrome is a form of cyclic vomiting that occurs with long-term, frequent cannabis use. The American Gastroenterological Association's 2024 clinical practice update describes it as seen predominantly in people who have used cannabis daily or near-daily for years, and lists its diagnostic criteria as:

• Episodes of vomiting that resemble cyclic vomiting syndrome, occurring 3 or more times a year
• Cannabis use for more than 1 year before symptoms began, on average more than 4 times a week
• Symptoms that resolve after stopping cannabis for at least 6 months, or for at least as long as 3 of that person's typical vomiting cycles

That last criterion explains why the condition is so often missed. Many people use cannabis precisely because it seems to settle nausea, and a few weeks without it may not be long enough to show the difference. A distinctive clue is relief from long hot showers or baths. In the same 2019 survey, 44 percent of people with cyclic vomiting reported a compulsive need for hot water bathing during symptoms, and cannabis use strengthened that behavior. This is relevant locally: Virginia has allowed adults 21 and older to possess up to one ounce of marijuana since July 1, 2021, and the Virginia Cannabis Control Authority states that retail cannabis sales begin July 1, 2027. A physician asks about cannabis to find the cause, not to judge, and an accurate answer can save months of testing.

Chronic nausea vomiting syndrome, when no other cause is found

Some people have ongoing nausea and vomiting, without the on-off pattern of cyclic vomiting, and a thorough evaluation finds no structural, metabolic, or medication cause. The AAFP review explains that the Rome IV criteria, the international standard for disorders of gut-brain interaction, call this chronic nausea and vomiting syndrome. It requires bothersome symptoms at least weekly for at least 3 months, and it can be diagnosed only after an evaluation that includes an upper endoscopy and rules out an eating disorder and other medical or psychiatric causes.

Receiving this diagnosis does not mean the symptoms are imagined or that nothing can be done. It means the problem lies in how the gut and brain communicate rather than in visible damage, the same framework used for IBS and functional dyspepsia. Treatment focuses on calming that signaling and improving daily function, and it is individualized.

How a gastroenterologist evaluates chronic nausea and vomiting

The evaluation starts with a detailed conversation, because history narrows the causes more than any single test. MedlinePlus lists the questions a provider typically asks: when the vomiting began, how long it lasts and how often it happens, whether it follows meals or occurs on an empty stomach, whether it includes undigested food, blood, or material that looks like coffee grounds, whether there is abdominal pain, fever, diarrhea, or headache, whether you have lost weight or traveled recently, what medications you take, whether you could be pregnant, and whether and how often you use marijuana. A physical examination checks for dehydration, abdominal tenderness, and other clues.

From there, testing is chosen based on what the history suggests. According to MedlinePlus and the AAFP review, it may include:

• Blood and urine tests. A blood count, electrolytes, and kidney and liver function, with thyroid testing, a pancreatic enzyme level, or a pregnancy test when relevant.
• Imaging. An abdominal ultrasound if gallstones are suspected, or a CT scan or X-ray if a blockage is possible.
• Upper endoscopy. A thin, flexible camera passed through the mouth to examine the esophagus, stomach, and first part of the small intestine for inflammation, ulcers, or a narrowing, with biopsies if needed. The AAFP notes it should be considered when an ulcer or reflux that does not respond to treatment is suspected, and it is a required step before diagnosing chronic nausea and vomiting syndrome. Our guide to upper endoscopy in Northern Virginia explains the procedure.
• Gastric emptying study. A scan that measures how quickly a small meal containing a tiny amount of tracer leaves the stomach. The AAFP notes it is used when no blockage or lining problem has been found and symptoms such as fullness after meals persist. The American Neurogastroenterology and Motility Society's 2019 guideline on cyclic vomiting syndrome in adults adds two practical cautions: the study should be done between episodes rather than during one, and both opioids and cannabis can slow stomach emptying and affect the result.

Not everyone needs every test. The purpose is to find the cause efficiently, starting with the most likely explanations and the ones that matter most to rule out.

Preparing for your visit

A short written record makes the first appointment far more productive. In the two weeks before the visit, if you can, note each day's symptoms, the time they started, what and when you last ate, whether you vomited and what it looked like, anything that helped (including hot showers), and anything that made it worse. Add your full medication and supplement list with start dates, any recent weight change, alcohol and cannabis use, and any family history of migraine. If you have had prior labs, imaging, or an endoscopy elsewhere, ask for the reports to be sent ahead.

If this is your first visit with a specialist, our guide to what to expect at a first gastroenterologist appointment walks through how it goes, and our guide to when to see a gastroenterologist covers when a referral makes sense.

General directions for managing chronic nausea and vomiting

Treatment depends on the cause, which is why the evaluation comes first. Once a cause is identified, treatment is aimed at it: healing an ulcer, treating H. pylori, managing reflux, adjusting a medication, addressing gastroparesis, or treating a metabolic or hormonal condition. While that work is underway, the AAFP review describes supportive measures that commonly help, including replacing fluids and electrolytes, eating small, frequent meals, and avoiding foods that trigger symptoms.

Anti-nausea medications can relieve symptoms, but the AAFP review notes that chronic symptoms are often harder to treat than acute ones and that these medications should be used for the shortest time necessary. Some carry specific limits. Metoclopramide, which is used for gastroparesis, is generally limited to 12 weeks because of the risk of involuntary movement disorders, according to the review. These are decisions to make with a physician who knows your history.

For cyclic vomiting syndrome, the ANMS guideline recommends a tricyclic antidepressant such as amitriptyline as a first-line preventive medication for adults with moderate to severe disease, used here to reduce the frequency of episodes rather than for depression, with other options available. It also recommends an individualized plan for treating acute attacks and screening for related conditions such as anxiety, migraine, sleep problems, and substance use. For cannabinoid hyperemesis syndrome, the AGA criteria make clear that sustained time without cannabis is both how the diagnosis is confirmed and the core of management.
