Although nausea will often happen, you should visit your doctor if you constantly suffer from nausea after eating, or if it is accompanied by severe pain, fever or other symptoms.
Eating too much can cause nausea, as your body tries to cope with extra food. This can happen in anyone, especially those who have had some type of surgery that reduces the ability of the stomach to store food. Eat slowly and only until your body tells you it is satisfied.
Unfortunately, during pregnancy, nausea can occur at any time, because your body is suddenly increasing its production of hormones. Sometimes, eating certain foods can cause nausea, while not eating enough too. The Cleveland Clinic suggests eating small meals with simple foods that do not irritate the stomach.
Occasionally, food may be contaminated with infectious organisms or toxins, causing food poisoning. Food poisoning usually occurs with nausea, vomiting and / or diarrhea within hours after eating the contaminated food. Usually, the symptoms disappear on their own, but serious cases may require the attention of a doctor.
