Causes of Nausea After Eating

Mechanism of Nausea often varies on the real reason causing the condition. The list of causes behind the medical condition of nausea after eating is very long. However, here is a detailed list of common causes of Nausea after eating.

1. Pregnancy

Well, this condition is applicable for only half of the world’s population. Feeling nauseated soon after eating is an early sign of pregnancy. Change in the hormone levels can result in pregnancy nausea. This is often accompanied with uneasiness and a queasy feeling. Though, this condition is medically termed as ‘morning sickness,’ but nausea after eating can strike at any time of the day. Sometimes, even the fragrance of any food can also trigger nausea after eating. However, the condition is temporary and cannot harm your body, you can use home remedies to treat the same.

2. Stomach Virus

Stomach virus which is also termed as ‘stomach flu’ can affect a person’s intestines and can result in gastrointestinal symptoms such as vomiting, diarrhoea, and even nausea after eating. A person can catch stomach flu through contaminated food or water or by getting too close to an already infected person.

3. Food poisoning

Food that is not cooked with quality ingredients or not through a proper channel invites lots of virus, bacteria, and parasites. Consuming such food can lead to food poisoning which can further lead to nausea after eating, diarrhoea, and even cause nausea after eating.

4. Acid Reflux

A burning sensation behind the breastbone is known as heartburn which is often the main symptom of the gastroesophageal disease (GERD). This medical condition can also lead to nausea after eating. GERD is caused due to the malfunctioning of the muscular valve between the stomach and the oesophagus. This leads to leaking up of stomach acid into the oesophagus.

5. Irritable Bowel Syndrome

Irritable bowel syndrome can lead to diarrhoea, abdominal pain, and even constipation. Nausea after eating is also a common occurrence among people suffering from this irritable bowel syndrome.

6. Motion sickness

Many people are often sensitive to long hours of movement, especially after eating. People suffering from this condition may feel sick due to the vehicle moving. Moreover, eating just before the starting of the journey can make the situation worse.

7. Gallbladder disease

Gallbladder is an organ that is situated on the upper side of the abdomen and helps in digesting fats. However, gallbladder diseases can adversely affect a person’s ability to digest fats. This can consequently lead to nausea after you eat a rich diet.

8. Cancer treatment

Another major cause of nausea after eating is the chemotherapy session for a cancer patient. Nausea after eating is often considered as a side effect of chemotherapy.

9. Anxiety and Stress

Stress hurts both your emotional and well as physical well being. Feeling nauseated especially after eating is a major cause of high level of stress.

10. Food allergies 

Some food items can trigger allergies in your immune system. Some people are allergic to food items such as nuts, fish, or eggs. Eating these food items can lead to triggering a series of events which consequently result in releasing of histamine and other chemicals in your body. These allergies often cause nausea after eating.
