People who often feel sick after eating are likely to suffer from acid reflux, which is associated with a chronic digestive disease called gastroesophageal reflux disease, according to Healthline. Foods with high fat content, peppermint, coffee, sodas, citrus fruits, tomatoes and alcohol are common causes of acid reflux.
Acid reflux occurs when a person has consumed food that is able to travel from the stomach back into the esophagus due to the malfunctioning of the individual's lower esophageal sphincter, explains Healthline. Stomach bile passes through this muscle along with undigested food and commonly causes feelings of nausea. Coughing and burping frequently accompany acid reflux queasiness. These symptoms can be combated by making simple lifestyle changes, such as eating smaller meals throughout the day to avoid overloading the stomach. People should also avoid tight clothing that places pressure on the stomach and refrain from lying down for at least two hours before bedtime.
It is crucial to stop smoking, as the nicotine present in cigarettes is known to weaken the LES between the stomach and the esophagus. Over-the-counter antacid tablets are available to counteract some of the nausea attributed to acid reflux. People can also try taking ginger supplements to minimize symptoms. If home remedies fail, Healthline recommends speaking with a doctor about the possibility of taking prescription medications.
