Lying Flat Causes Nausea And Vomiting But Symptoms Disappear When Lying On One's Side: What Could Be The Reason?

Many people experience nausea or even vomiting when lying flat on their back, but find relief when switching to a side-lying position. This phenomenon may be linked to a common gastrointestinal condition known as chronic superficial gastritis.

Understanding Chronic Superficial Gastritis

Chronic superficial gastritis is a type of inflammation that affects the inner lining of the stomach. It often occurs due to factors such as exposure to cold temperatures, bacterial infections (especially Helicobacter pylori), or irregular eating habits. When the stomach lining becomes inflamed, it can lead to a variety of symptoms including loss of appetite, nausea, vomiting, bloating, acid reflux, and stomach pain.

Why Symptoms Improve When Lying On The Side

When a person lies flat on their back, stomach acid may more easily rise into the esophagus due to gravity, worsening symptoms like nausea and discomfort. However, lying on one's side—especially the left side—can help keep stomach acid from refluxing, thereby reducing nausea and providing relief.

Recommended Diagnosis And Treatment

If you frequently experience nausea when lying flat, it is important to consult a healthcare professional. A gastroscopy can help diagnose the condition accurately. Based on the results, a doctor may prescribe a combination of medications such as clarithromycin dispersible tablets, rabeprazole sodium enteric-coated tablets, and aluminum magnesium carbonate chewable tablets to manage symptoms and treat the underlying cause.

Importance Of Dietary And Lifestyle Changes

In addition to medical treatment, making lifestyle adjustments is crucial. Patients should maintain a regular eating schedule, avoid spicy, oily, or acidic foods, and reduce alcohol and caffeine intake. Eating smaller, more frequent meals and avoiding lying down immediately after eating can also help manage symptoms effectively.
