In addition to allergies, some people suffer from low gastrointestinal function. Eggs contain a large amount of protein and riboflavin, so eating eggs properly can replenish the nutrients needed by the body, but some people are allergic and will show an allergic reaction after ingesting protein, when the patient will experience nausea and vomiting. Although eggs are rich in nutrients, they are difficult to digest. People with low gastrointestinal function will experience nausea after eating eggs because the digestion time of eggs is relatively longer and the digestion process causes some stimulation to the stomach. Since eggs have a fishy taste, some people are not particularly adapted to these flavors and may experience nausea as a result of a nervous reaction after ingestion.
