Nausea After Eating : Is It Your Head or Stomach?


Nausea after Eating is more or less a common occurrence and can be caused by many conditions; some of the causes are physiological, while some other ones are pathological.  Continue reading to find out about the various causes of nausea after eating.


Nausea is a general medical term that describes a discomfort to the upper part of the stomach, often accompanied by a particular sense of vomiting.

Nausea is a symptom and not a condition; it is prevalent and characterizes a large number of diseases.

The sense of vomit, which accompanies most of the episodes of nausea, may remain such or may result in actual vomiting.

Here are some of the most common causes of nausea after eating.

  • Food poisoning: it is among the leading reasons for admissions in the Emergency Room for nausea, and vomiting after eating. Symptoms usually appear just after ingestion of food contaminated with toxins or microorganisms that cause intoxication. Associated symptoms are vomiting, stomach cramps and diarrhea.
  • Gastroenteritis: it is a viral infection that affects the stomach and develops when the person consumes food contaminated by the virus or comes into contact with other sick people. Symptoms include nausea, vomiting, diarrhea and abdominal cramps.
  • Anxiety and stress: it is scientifically proven that emotions affect hormone production and the secretion of chemical mediators. If you eat under stress or worries, the creation of hormones and digestive enzymes may be altered, and manifest with nausea and poor digestion and intestinal problems.
  • Gastroesophageal reflux: due to the poor seal of the valve that separates the stomach and esophagus, part of the gastric juices can drain into the esophagus, causing belching and nausea after eating.
  • Indigestion: it’s the first thing you think about when you have nausea after eating. Excess food, fats or carbonated beverages can interfere with digestion, blocking it or just slowing it down. The first symptom is nausea.
  • Food allergies: some allergies to foods, chemicals or preservatives, may occur with nausea after eating.

Constant Nausea

Nausea after eating does not have a fixed duration, but usually, mainly if the person who suffers from nausea succeeds in vomiting tends to disappear in a short time. If nausea after eating turns into constant nausea the causes may be different from the food.

For example, it is possible to have constant nausea due to a hormonal overhang (a condition common to women during the menstrual cycle), or it could be a symptom of a severe problem of the stomach or digestive health.

Also, constant nausea can be a symptom of some cancers, such as brain tumor or can occur in the event of a severe migraine.

In cases of constant nausea, it is imperative to consult a doctor immediately.

Nausea After Eating

After-eating sickness is a widespread disorder in people, primarily when they have consumed a significant amount of food (much more than their average food ration) or something they have eaten has not been adequately assimilated by the body, triggering nausea after eating.

Multiple causes can trigger nausea after eating, and every symptom can be the principle of more severe problems. To think that it is all the fault of food when it comes to nausea after eating is a wrong approach because the food is just one of the various causes that can generate this disorder.

When we eat too much the walls of the stomach relax, the stomach expands to make us feel all that.

In this process, however, the produced gastric juices cannot act on the whole contents of the stomach.

Hence the feeling of heaviness, nausea, difficulty in digesting, drowsiness and malaise. There may, however, be other reasons why you feel nauseous after eating and are not always due to overeating.

Let’s find out more about the other causes and remedies of nausea after eating, and go deeper into what nausea is.

Mild Nausea After Eating

After-eating nausea can manifest itself in many ways and different intensities. Mild nausea after eating can be a passing disorder or the result of a meal that is too abundant. To prevent this disease it is important to try not to overeat food (especially in the evening) and to check the expiry dates of dairy products and eggs. Never consume these foods after the date of expiry.

In any case, it is essential not to underestimate mild nausea after eating because it is still a manifestation of a problem. You can use drugs, digestives (such as baking soda) or natural remedies to solve this type of after-eating nausea. If the trouble persists, consult a doctor.

Nausea After Eating Early Pregnancy

Nausea after eating early pregnancy occurs in the first (mainly for hormonal reasons) and the last (by stomach compression) trimester of pregnancy often happens nausea, after eating and at other times of the day and can be accompanied by vomiting.

Pregnancy nausea is not considered a pathological but a paraphysiological manifestation.

It can instead give some problems when it is so intense as to produce an excessive loss of fluids and nutrients with vomiting until the mother’s weight decreases (which in the first trimester should increase, even if only one or two kg). In these cases, especially when the nausea is accompanied by a sense of general malaise, it is good to seek medical attention.

Nausea Medicine During Pregnancy

Doctors do not recommend taking nauseous drugs for pregnancy and prefer to support healthy eating habits and the use of some natural remedies.

Here’s what to do to avoid taking nausea medicine for pregnancy:

  • Eating habits: eat little and often, to keep blood sugar high: choose foods such as biscuits, crackers or bread; prefer light foods such as bananas, pasta, and potatoes. Eliminate fried foods, fatty and spicy foods that increase nausea. Drink juices and smoothies, which maintain blood sugar levels, and avoid caffeine-rich beverages. Take ginger or ginger essential oil; it is a natural alternative to medicines.
  • Physical activity: it takes just 15 minutes of quick walk to encourage the production of endorphins by the body, to combat nausea.

Nausea Medicine

Many nausea medicines differ depending on the origin of the problem and more household and generic remedies, such as sodium bicarbonate, but many doctors recommend replacing the nausea medicine with natural resources, not to subject the body and stomach to stress further.

Remedies like ginger, cloves, lemon juice, peppermint and anise seeds are excellent nausea medicines that naturally cure the problem of nausea after eating.


A Headache and Nausea

A migraine is a severe form of a headache, and it is associated with certain symptoms, like a headache, nausea, flu, fever, body aches, chills, diarrhea and runny nose to mention just a few.  Despite the relationship between a headache and nausea, scientists are not clear yet about how a headache can lead to nausea.  Though, many theories have been propounded in this regard.

According to one of the theories, the condition is caused by serotonin and scientists are of the opinion that certain nerves in the brain can signal the blood vessels located in the brain. The blood vessels then get enlarged due to low serotonin. Low serotonin is equally responsible for nausea and motion sickness.

Aside from the theory described above, some other factors are also thought to link nausea with a headache.

Feeling Nauseous

Certain factors can make you feel nauseous, and we are going to enumerate some of the factors below:

First and foremost, you can feel nauseous if you are undergoing anxiety or stress. Either of these can affect your gut and make you feel nauseous. Stress may be a form of emotion, but it can still lead to nausea via a cascade physical change in the human body.  Stress leads to negative feelings in the body, and the gut is one part of the human body that is highly sensitive to such negative feelings.  The human gut has numerous nerves covering it and these nerves contact and expand the intestine and push the food downward in the digestive tract. You may not believe it, but this problem can be fixed by just drinking a lot of water. Also, taking foods, like bread, dried fruit, fresh fruit or fruit juice can also fix the problem effectively.

Morning Sickness

Other names for morning sickness are nausea and vomiting of pregnancy (NVP), pregnancy sickness, emesis gravidarum and nausea gravidarum.  It is one of the many symptoms of pregnancy, and it involves nausea and vomiting. Its name gives the impression that it occurs during the morning, but the pregnant woman can experience it at virtually any time of the day. In most instances, morning sickness takes place between week 4 and week 16 of pregnancy. It can also extend until the 20th week of pregnancy in about 10% of women.  Hyperemesis gravidarum is a more severe form of morning sickness, and it can lead to weight loss in the affected woman.  If not treated on time, the condition can lead to oesophageal rupture and Wernicke encephalopathy.  Researches are still on-going about the cause, but no specific cause had been detected for the condition yet.

Nausea and Vomiting After Eating Anything

Many conditions can make you feel like vomiting after a meal. It can be caused by pregnancy or food poisoning. Food allergies can be responsible for this condition. Examples of such foods are eggs, nuts, and shellfish. Such foods are also referred to as trigger foods. The immune response is stimulated and lead to the production of histamine, as well as several other chemicals. The chemicals lead to the production of allergy symptoms, like nausea, mouth swelling and hives.   Nausea and vomiting after eating anything can also be caused by food poisoning, stomach virus, pregnancy, acid reflux, anxiety and stress, cancer treatment, gallbladder disease, irritable bowel disease and morning sickness.

Nausea After Eating Gallbladder

Nausea after eating gallbladder can come up individuals that have gallbladder disease. The gallbladder is a unique organ in the human. It is located in the right upper quadrant of the human abdomen and involved in fat digestion. Individuals having gallbladder diseases, like gallstones, can face difficulty in fat digestion. As a result, they will end up with feelings of sickness to their stomachs; this usually happens after they have consumed meals rich in fat.  When you have a problem digesting fat, the body will automatically reject the food in your digestive tract; this will lead to a disorder in digestion, leading to feelings of vomiting. It must be noted that several factors, aside from gallbladder problem, can lead to nausea after eating.
