Nausea and headache are signs that the body needs a timeout to help bring itself back to its normal state. Finding the cause is the first step to understand the treatment. Unfortunately, there are hundreds of reasons why a person can experience both nausea and headache. A person who is experiencing nausea should consult a physician if it lasts more than one week, and if there is a possibility of pregnancy. When trying to control nausea:
*Drink clear or ice-cold drinks.
*Eat light, bland foods (such as saltine crackers or plain bread).
*Avoid fried, greasy, or sweet foods.
*Eat slowly and eat smaller, more frequent meals.
*Do not mix hot and cold foods.
*Drink beverages slowly.
*Avoid activity after eating.
*Avoid brushing your teeth after eating.
*Choose foods from all the food groups as you can tolerate them to get adequate nutrition.
Treatment for vomiting (regardless of age or cause) includes: drinking gradually larger amounts of clear liquids; avoiding solid food until the vomiting episode has passed; resting; and temporarily discontinuing all oral medications, which can irritate the stomach and make vomiting worse.
