Feeling dizzy, nauseous, and having the urge to vomit upon waking up in the morning can be caused by various factors.

1. Hypoglycemia: Prolonged fasting can lead to decreased blood sugar levels, a condition more commonly seen in individuals with diabetes. Hypoglycemia can cause dizziness and nausea.

2. Dehydration: Fluids are lost overnight through breathing and perspiration. If adequate hydration is not maintained before sleep, one may feel dehydrated in the morning, which can lead to dizziness and nausea.

3. Inner ear problems: The inner ear is responsible for maintaining body balance. Conditions such as Ménière's disease or vestibular neuritis can cause dizziness and nausea, especially when changing head positions.

4. Abnormal blood pressure: Both high and low blood pressure can lead to dizziness. Changes in blood pressure upon waking up in the morning may cause discomfort in some individuals.

5. Anxiety or stress: Psychological status has a direct impact on the body. Excessive anxiety or stress can manifest as physical symptoms, including dizziness and nausea.

For these symptoms, it is recommended to seek medical attention promptly. Additionally, maintaining good sleep habits, sufficient rest, a balanced diet, and appropriate exercise can help prevent and alleviate these symptoms.
