Why do migranes make you feel nauseous?

Answer 1

Well, I know that the part of your body that triggers throwing up and vomiting is located in the brain. ( The brain sends the signals to your diaphragm to initiate the sudden contractions which lead to regurgitation. During a migrane, the blood vessels expand to such a degree, pressure gets applied to essentially every part of the brain. That is why hearing is ultra-sensitve and why bright lights do you in. But on the same note, the enlargened blood vessels put pressure on that area of the brain too.

Answer 2

There are often symptoms which precede the attack by several hours or days manifested generally by emotional or mental disturbances, digestive upsets, and fluid imbalances. Neurologic manifestations may occur of a visual nature such as rainbows around lights, streaks or pings of light, but may also include loss of appetite, nausea and vomiting, and other neurologic features.

What Could cause the pain or nausea:

Migraine can be most easily explained as an allergy, the pain being caused by the release of chemical substances in the brain and other tissues following an allergic reaction. Foods responsible for the antigen:antibody reactions account for the presence in the tissues of the body of chemicals that cause the headache — noradrenaline, histamine, and other substances capable of irritating blood vessels.

Triggering Agents

A migraine headache may be caused by foods to whichone is allergic, but then precipitated by different triggering agents. As an example: the cause of a migraine may be cheese or perfume allergy, whereas the trigger may be an emotional upset. Other triggers may be various foods in addition to the cause (see below) such as chocolate or apples.

Low blood sugar (hypoglycemia), tension, depression, alcohol, tobacco, birth control pills, vasodilator drugs, salt, food additives, water retention, menstruation, wind exposure, and sun exposure are other triggering agents. There may also be multiple aggravating factors which may neither cause nor trigger an attack but make it worse once it occurs. The aggravating factors include poor air, constipation, chilling, noise, etc.
