Nausea after recovering from COVID-19

“Post-recovery from阳康” refers to the period after recovery from a novel coronavirus infection. If patients experience nausea during this phase, it may be caused by improper diet, incomplete physical recovery, chronic gastritis, or other factors. If the nausea results from dietary issues, adopting healthy lifestyle habits is usually sufficient. However, if it stems from incomplete recovery or conditions like chronic gastritis, further medical evaluation and treatment at a hospital are necessary.

1. Improper Diet

After recovery, patients' gastrointestinal systems remain relatively weak. Consuming raw, cold, or spicy foods—such as ice cream, chilled watermelon, green onions, or chili peppers—can irritate the gastrointestinal mucosa, causing intense contractions and leading to nausea. This condition is generally mild. It is recommended that patients avoid overeating, drink more warm water, and consume light, nutritious, easily digestible foods such as bone soup or steamed egg custard. Additionally, they should keep their stomach warm, avoid excessive fatigue, and ensure adequate sleep.

2. Incomplete Physical Recovery

After being invaded by the novel coronavirus, the body releases large amounts of toxins into the bloodstream, which can irritate the gastrointestinal mucosa and cause nausea. Patients are advised to take medications such as lansoprazole enteric-coated capsules or omeprazole enteric-coated capsules under medical guidance.

3. Chronic Gastritis

Patients with pre-existing chronic gastritis may experience increased gastric acid secretion, leading to spasms in the stomach's smooth muscle tissue. Since the novel coronavirus has certain irritating effects on the gastrointestinal tract, it may trigger or worsen symptoms such as nausea and vomiting. In such cases, patients may follow medical advice to take medications like cimetidine tablets or pantoprazole sodium enteric-coated tablets to suppress gastric acid secretion.
