Connecting nausea and vomiting to my symptoms

Record the feeling of nausea and the actual number of times you vomited separately

Nausea is the feeling that you might throw up, and vomiting is the state where stomach contents have actually come out. It is helpful for identifying the cause if you can specify whether it happened before a meal or several hours after, when the vomited food was eaten, and whether headache, dizziness, or abdominal pain came first.

Seek medical attention immediately if you cannot keep down water or if blood is visible

Immediate evaluation is necessary if there is blood or coffee-ground-like material, green-colored vomit, severe abdominal or headache pain, or changes in consciousness. Do not wait if there is dehydration, characterized by decreased urine output, dry mouth, and dizziness. Post-meal nausea that recurs after the condition has stabilized will be treated during the consultation.

After vomiting, check the amount you can drink and your urination

Check if you can keep down a sip of water, the time and color of your last urination, and any dizziness or dry mouth. Record the frequency and contents of vomiting, the last meal or medication, the possibility of pregnancy, and the sequence of headache or abdominal pain. Blood or coffee-ground-like material, green-colored vomit, changes in consciousness, or severe dehydration require immediate medical attention. Also, report your body temperature and any recent travel or exposure to infections.
