Hello,
Headache with
vomiting is indicative of
tension headache &
migraine. Other medical cause can be
dehydration, low BP, low glucose level, stress & anxiety.
If you all are sexually active take proper birth control precautions, you have not mentioned it here. Headache with vomiting may be a sign of
pregnancy if your girlfriend has delayed or missed periods.
Help her stay away from anxiety & stress, she should avoid oily, spicy food & exposure in bright light. Let her stay well hydrated, she can take ORS & soup, water or any other warm beverage to keep her body electrolyte system well balanced.
Get her clinically examined in ER, her vitals should be normal. She can take Advil or Motrin for pain & an anti emetic medicine to avoid vomiting.
She should avoid addictions if any, take food in small amount 4-5 times a day. Exercise regularly & take adequate sleep.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr. Nupur K
