I feel nauseous in the morning when I get up early.

Dry heaving upon waking up early in the morning may be caused by physiological factors or pathological conditions such as gastroesophageal reflux and chronic pharyngitis. It can be improved through general treatments or medication. Specific analyses are as follows:

I. Physiological Factors

For example, early pregnancy reaction: menstruating women who experience amenorrhea along with morning dry heaving may be experiencing symptoms of early pregnancy. In such cases, a urine pregnancy test can be performed, or blood tests and abdominal ultrasound examinations can be conducted at a hospital.

II. Pathological Factors

1. Gastroesophageal Reflux

When contents from the stomach or duodenum reflux into the esophagus, it may cause heartburn and damage nearby tissues such as those affected by reflux esophagitis, pharyngitis, or airways, leading to dry heaving. Under medical guidance, medications such as rabeprazole sodium enteric-coated capsules or omeprazole magnesium enteric-coated tablets may be used for treatment.

2. Chronic Pharyngitis

This commonly occurs during dry seasons like autumn and winter. Patients with chronic pharyngitis may feel irritation or a foreign body sensation in the throat upon waking up in the morning, and may even experience nausea and dry heaving. Treatment may include using compound borax mouthwash or compound chlorhexidine mouthwash under medical supervision.

Besides the above, dry heaving could also result from conditions such as chronic gastritis, gastric ulcer, or duodenal ulcer. It is important to seek timely medical attention, identify the underlying cause under the guidance of a qualified physician, and adopt appropriate treatment measures.
