Nausea after eating – constant nausea and stomach ache

Constant nausea after eating

Nausea is that discomforting feeling which usually precedes a bout of vomiting.  Common characteristics of nausea is the feeling of being lightheaded or dizzy accompanied by an upset stomach.  Feeling sick after eating is frequently felt by many people immediately following food consumption.  While nausea usually occurs directly after meal ingestion, a nauseous event can also occur a while afterwards.

Most Common Causes of Nausea

There are many causes of being nauseated after eating.  The causes range from simple improper eating to food allergies; and from stomach flu to cancer.  The following is a list of conditions that could be the underlying cause of your chronic nausea:

food borne illness – the ingestion of food contaminated with bacteria. Nausea is a primary symptom of food poisoning. Other symptoms of food poisoning are similar to gastroenteritis and are described below.

food content — certain foods and food ingredients do not agree with some people’s digestive tracts.  The result is poor food digestion, nausea, and vomiting.  Rich and fatty foods are common culprits of nausea after eating.  A sensitivity to wheat or dairy products are also common culprits for constant nausea.  Wheat and dairy products are additions in many processed foods.  Try eliminating these from your diet and see if you experience any improvement with your symptoms.

Improper eating — eating food too quickly, eating too much, or not chewing your food enough can all leave you feeling nauseous.  Too frequent or too infrequent meal consumption are  common reasons for nausea after eating as well.  It is important to note that you may actually be experiencing indigestion, which is heartburn coinciding with nausea.

Indigestion – Nausea can also be associated with dyspepsia (commonly referred to as indigestion). Other symptoms of dyspepsia are bloating, stomach pain, burping, and gas.

Acute gastroenteritis — gastroenteritis is an illness characterized by nausea, diarrhea, and vomiting.  These bouts of stomach flu are bacterial, viral, or parasitic in origin.  Another type of gastroenteritis is called eosinophilic gastroenteritis which is a gastric mucosal malady where nausea and vomiting are present.

Gastroesophageal reflux disease (GERD) — symptoms of GERD are heartburn, regurgitation, and dysphagia.  Individuals with GERD experience differing amounts of stomach acids mixed with undigested foods returning to the esophagus from their stomach.

peptic disease–  erosions in the lining of the esophagus, stomach, or duodenum. People who have a peptic disorder commonly experience mild nausea, reflux, and other digestive symptoms. Alcohol use, anti-inflammatory medications, smoking, and illness can all result in a peptic flare up—contributing to your nauseated feeling.

Rumination — the rumination syndrome is daily, effortless regurgitation of undigested food within minutes of starting or completely ingesting a meal.

Cyclic vomiting syndrome — disorder characterized by repeated episodes of nausea and vomiting that last for hours or days separated by differing periods with no symptoms at all.

Metabolic disturbances — diabetes, adrenal imbalance, hypercalcemia, or pregnancy can all be common causes of nausea after eating.


Psychological – sometimes worrying about problems in your everyday life can cause you to experience episodes of nausea. Also of importance to note is that some psychological disorders such as bulimia, even if you are no longer bulimic, can result in you experiencing nausea as the body has become accustomed to getting sick.

Appendicitis — feeling nauseous after eating could be a symptom of appendicitis.  Especially if it is accompanied by pain in the lower right quadrant of your body around your stomach.  Seek a physician immediately if your nausea is accompanied by this pain.

Gallstones — stomach pain which occurs higher than appendicitis pain. This is also accompanied by nausea, particularly in association with the consumption of greasy foods.


Viral gastroparesis.

Chronic idiopathic intestinal pseudo-obstruction

Acute non-G.I. infections, kidney or pneumonia.

hepatobiliary disease.

Pancreatic disease.

Gastric or ovarian cancer.

CNS (central nervous system) diseases — infections, tumors, multiple sclerosis.


As you can see, nausea after eating can be from something simple such as improper eating to viral gastroenteritis to cancer.  If you continue to experience nausea after eating despite medication and other treatment methods, a serious medical condition could be the underlying problem and you should seek treatment from a medical physician immediately.
