Causes of feeling nauseous after eating:
Feeling nauseous after eating is caused by innumerable causes. Let us look at all the possible causes of feeling sick after eating.
Inappropriate eating habits:
We need to eat very slowly and chew eat a bite of food for 32 times in order to incorporate the saliva and salivary enzymes in the food. This enables easy digestion of the food and prevents all the gastric troubles.
But, some people have the habit of eating very fast. They also chew the food very fast and less than the required number of times. This can lead to indigestion, which can, in turn, lead to feeling nauseous after eating.
Having long gaps between meals:
Many people have the habit of eating only once or twice in a day. During these meals, they tend to eat heavy meals. As these people have long gaps between the meals, acids accumulate in the stomach for prolonged periods.
When gastric acids accumulate for long periods, you will surely experience feeling sick after eating. In order to avoid such problems, make sure to have small gaps between your meals.
Eat number of meals frequently. But, make sure to eat only small quantities of food during these meals.
Mental stress and anxiety play a vital role in causing many diseases. Feeling nauseous after eating is no exception to that. If you are feeling very stressed, anxious or depressed, you tend to activate your sympathetic nervous system.
When the sympathetic nervous system is activated, the hormones or neurotransmitters like catecholamines (epinephrine and norepinephrine) are triggered. They lead to the fight or flight response.
During the fight or flight response, all the blood in the body is diverted to the muscles, heart, respiratory tract, etc. This makes you breathe fast, have rapid heartbeat or palpitations, etc.
Adequate blood is not supplied to your digestive tract. This makes you feel nauseous after eating.

Many drugs like NSAIDS or nonsteroidal anti-inflammatory drugs, eating spicy food can aggravate the peptic ulcers.
People suffering from peptic ulcer disease have pain behind the sternum or pain below the ribs, that is an epigastric pain. They also have reflux of acidic contents into the esophagus and mouth. In addition to these symptoms, they also feel nauseous after eating.
