Nausea Explained: What Causes Vomiting After Eating?

Vomiting in Singapore after eating can be a distressing experience and can indicate various underlying health issues. Understanding the potential causes is essential for seeking appropriate treatment.

Common Causes of Vomiting After Eating

1. Food Poisoning

Consuming contaminated food can lead to food poisoning, causing symptoms like nausea, vomiting, diarrhoea, and gastric pain in Singapore. Bacteria like Salmonella and E. coli are common culprits. Food poisoning can occur if food is not cooked or stored properly. Symptoms usually appear within hours of consuming contaminated food and can last for several days. It’s crucial to stay hydrated and seek medical attention if symptoms are severe.

2. Gastroenteritis

Often referred to as the stomach flu, gastroenteritis is an inflammation of the stomach and intestines caused by viruses, bacteria, or parasites. Symptoms include nausea, vomiting, diarrhoea, and cramps. Viral gastroenteritis is highly contagious and spreads through close contact with an infected person or through contaminated food and water. Maintaining good hygiene practices can help prevent the spread of gastroenteritis.

3. Peptic Ulcers

Ulcers in the stomach lining or the upper part of the small intestine can cause nausea and vomiting after meals. These ulcers are often caused by H. pylori infection or long-term use of NSAIDs. Peptic ulcers can lead to complications like bleeding, perforation, and obstruction if left untreated. Treatment typically involves antibiotics to eradicate H. pylori and medications to reduce stomach acid.

4. Gallbladder Disease

Conditions like gallstones or cholecystitis can cause vomiting after eating, especially if the meal is high in fat. Symptoms also include pain in the upper right abdomen. Gallstones form when substances in bile, such as cholesterol, harden. If a gallstone blocks a bile duct, it can lead to inflammation and infection. Treatment may involve medication to dissolve the stones or surgery to remove the gallbladder.

5. Food Allergies

Allergic reactions to certain foods can cause nausea and vomiting. Common allergens include nuts, shellfish, dairy, and eggs. Food allergies occur when the immune system mistakenly identifies a harmless food protein as a threat. Symptoms can range from mild to severe and may include hives, swelling, and anaphylaxis. It’s important to identify and avoid trigger foods and carry an epinephrine auto-injector if prescribed.

6. Gastroparesis

This condition slows or stops the movement of food from the stomach to the small intestine, causing nausea, vomiting, and bloating. It’s often associated with diabetes. Gastroparesis can lead to malnutrition and severe dehydration if not managed properly. Treatment may include dietary changes, medications to stimulate stomach contractions, and, in severe cases, surgical interventions.

7. Psychological Factors

Stress, anxiety, and eating disorders like bulimia can trigger nausea and vomiting after meals. Psychological factors can affect the brain-gut connection, leading to digestive issues. Addressing underlying psychological conditions through therapy, medication, and lifestyle changes can help alleviate symptoms.

8. Motion Sickness

Sensitivity to certain movements, especially while travelling, can cause motion sickness, leading to vomiting after eating. Motion sickness occurs when there is a disconnect between what the eyes see and what the inner ears sense. Using over-the-counter medications, acupressure wristbands, and focusing on the horizon can help manage symptoms.

9. Medications

Some medications can irritate the stomach lining, causing nausea and vomiting as side effects. Common offenders include chemotherapy drugs and certain antibiotics. Taking medications with food, adjusting dosages, or switching to alternative drugs can help reduce gastrointestinal side effects. Always consult with a healthcare professional before making any changes to medication regimens.

10. Pregnancy

Morning sickness is common during pregnancy, especially in the first trimester, causing nausea and vomiting after meals. Hormonal changes, particularly increased levels of human chorionic gonadotropin (hCG), are believed to contribute to morning sickness. Eating small, frequent meals, staying hydrated, and avoiding triggers can help manage symptoms.

When to Seek Medical Attention

While occasional vomiting might not be a cause for concern, persistent vomiting can indicate a more severe condition that requires medical attention. You should consult a healthcare professional if you experience:

• Vomiting that lasts more than 24 hours
• Severe abdominal pain
• Blood in vomit
• High fever
• Dehydration symptoms, such as dry mouth, dizziness, or reduced urination

Conclusion

Persistent vomiting after eating can lead to dehydration and other serious complications, making it crucial to identify and address the underlying cause. Whether it’s due to food poisoning, gastroenteritis, peptic ulcers, gallbladder disease, food allergies, gastroparesis, psychological factors, motion sickness, medication side effects, or pregnancy, understanding these potential triggers is essential for effective treatment and prevention. By recognising the symptoms and seeking timely medical attention, individuals can manage their health more effectively.
