What causes cold rice-like lumps?

Generally, "cold rice lump," also known as post-meal lump, refers to a feeling of stomach discomfort and pain that occurs after eating, especially following the consumption of cold rice. This may be caused by factors such as food residue, indigestion, or acid reflux. The specific causes are analyzed as follows:

1. Food residue: Cold rice often develops uneven temperature distribution during refrigeration or reheating, which may lead to prolonged retention in the stomach. As a result, the stomach requires more time and energy to digest the food, potentially causing bloating and discomfort.

2. Indigestion: Some individuals may have intolerance to certain foods or ingredients, such as high-fat, spicy, or greasy foods, which can lead to indigestion and gastric discomfort.

3. Acid reflux: Acid reflux, also known as gastroesophageal reflux, occurs when stomach acid flows back into the esophagus. This may cause inflammation and irritation of the esophagus and stomach, resulting in discomfort and pain.

In addition to the above common factors, chronic gastritis could also be a possible cause. It is recommended to seek timely medical evaluation at a hospital to determine the underlying cause and receive targeted treatment. In daily life, maintain healthy habits and avoid consuming spicy or irritating foods to promote recovery.
