What should I do if I wake up in the morning feeling nauseous and like vomiting?

The treatment for morning nausea and vomiting upon waking depends on the specific underlying cause, which may include sleep deprivation, low blood pressure, chronic pharyngitis, gastritis, or gastric ulcers.

1. Sleep Deprivation

Prolonged熬夜 leading to insufficient sleep can result in excessive physical fatigue and mental stress, irritating the gastrointestinal tract and allowing stomach acid to enter the esophagus, causing symptoms such as heartburn, nausea, and vomiting. It is recommended to create a good sleep environment and ensure adequate rest; symptoms will gradually improve with sufficient sleep.

2. Low Blood Pressure

When blood pressure falls below the normal range, blood flow to the brain may decrease, resulting in cerebral hypoperfusion. This is especially noticeable when transitioning from a lying position to sitting or standing, leading to symptoms such as nausea, dizziness, and the urge to vomit. Ensuring adequate sleep and rest, along with moderate exercise, can help improve heart health and circulation, thereby alleviating symptoms.

3. Chronic Pharyngitis

Chronic inflammation of the pharyngeal mucosa, submucosal tissue, and lymphoid tissues can lead to throat inflammation. Irritation of the pharyngeal mucosa may cause sore throat, nausea, and vomiting. It is recommended to take medications such as cytidine iodide tablets, menthol lozenges, or watermelon frost throat lozenges under medical guidance to relieve symptoms.

4. Gastritis

This condition may lead to increased gastric acid secretion or impair the protective barrier of the gastric mucosa, allowing stomach acid to reflux into the esophagus (acid reflux), irritating the gastric lining and causing symptoms such as vomiting, nausea, and stomach pain upon waking. Under medical supervision, medications such as bismuth potassium citrate capsules, hydrotalcite chewable tablets, or sucralfate tablets may be taken to protect the gastric mucosa and improve symptoms.

5. Gastric Ulcer

When ulcers or erosions develop in the gastric mucosa, gastric acid contacting the ulcerated areas can irritate the lining, causing stomach pain, nausea, and vomiting. Under medical guidance, medications such as famotidine tablets, ilaprazole enteric-coated tablets, or pantoprazole sodium enteric-coated tablets—used to suppress gastric acid secretion—can be taken to relieve symptoms.

It is recommended to seek medical attention at a hospital, undergo thorough evaluation under a doctor's guidance, and receive appropriate treatment to alleviate symptoms. During illness, prioritize adequate rest and avoid spicy or irritating foods; opt instead for light, easily digestible meals.
