How Our Diets Affect Migraine
Many things can trigger a migraine attack, including what we eat and drink.
According to the Migraine Research Foundation, foods that trigger migraine may only do so when combined with other triggers. But this combination and any trigger in general is highly individualized, making research difficult.
Theres no such thing as a universal migraine trigger. But there are some common triggers that can cause or contribute to migraine episodes in some people.
But according to the American Migraine Foundation, caffeine can actually help stop oncoming migraine attacks. It can also offer headache relief with occasional use.
Foods and drinks with caffeine include:
one study , over 35% of the participants with migraine reported that alcohol was one of their common triggers.
Red wine in particular was reported as a trigger in over 77% of the participants who reported alcohol as a trigger.
Alcohol can cause dehydration, which is a significant contributor in developing headaches.
According to the American Migraine Foundation, chocolate is thought to be the second most common trigger for migraine attacks after alcohol. They say it affects an estimated 22 percent of people who experience migraine.
Chocolate contains both caffeine and beta-phenylethylamine, which may trigger headaches in some people.
Can I Have A Visual Migraine Without A Headache
Definitely. It is actually very common to have a visual migraine without any headache. The medical term for this is acephalgic migraine, which literally means migraine symptoms without headache.

What Does An Ocular Migraine Feel Like
An ocular migraine begins with a sparkling and shimmering area that has a jagged border and that gradually spreads outward. It causes a small blinding spot that enlarges and blocks your vision temporarily. The brightness begins at the edge of your field of vision and gradually spreads to your line of vision. Zigzag lines or stars may also be seen. It is almost like looking through a broken window. Scotoma is the area where vision is disrupted and the whole episode is called a positive aura.
An ocular migraine is often referred to differently by different experts. While many call it a visual migraine or a typical aura without headache, the International Headache Society classifies such a migraine as a silent or acephalgic migraine.
Though it seems serious since you lose your vision partially, the condition is usually harmless and will resolve on its own within 2030 minutes without any medical intervention. Complete visual darkness, or a negative aura, is not a symptom of an ocular migraine, but of some other underlying condition that needs to be investigated.2

Henry HoffmanThursday, September 27th, 2018
Today, migraines are considered the most common neurological disorder according to the Journal of Stroke, and, in the United States alone, about30 million people suffer from these debilitating headaches. Research has determined that all migraineurs are at a higher risk of suffering a stroke, and this risk factor is potentiallydoubled or tripled for individuals who suffer from migraines with visual disturbances collectively known as aura.
Unfortunately, migraines with aura exhibit similar symptoms to those associated with certain life-threatening conditions, namelytransient ischemic attacks and strokes. For this reason, many migraineurs may mistake early stroke warning signs for classic migraine symptoms. Telling the difference and recognizing a medical emergency for what it is can be difficult, but isnt impossible.

Migraines are less likely to cause “negative” symptoms of pure visual darkness. An episode of visual darkness typically requires additional evaluation for other conditions, including a mini-stroke .
What Triggers An Ocular Migraine
Ocular migraines can be triggered by a number of factors. Quite often, people are genetically predisposed to suffering more from migraines, especially women aged under 40. Otherwise, ocular migraines can be brought on by:
- Bending over or standing up quickly
- High altitude or changing weather
- Bright lights
- Consumption of certain foods, caffeine or alcohol
- Changes in hormone levels e.g. pregnancy or menopause

An aura is a temporary visual, auditory, motor, or other sensory change. Visual disturbances can be:

How Long Do Ocular Migraines Last
Most of the time, ocular migraines are relatively short-lived in duration. Sometimes, they last for as little as 20-30 minutes before disappearing completely. In other cases, especially if they are accompanied by more traditional migraine symptoms, ocular migraines may last longer. If your vision does not return within an hour, contact a doctor, or seek emergency care to ensure your migraine symptoms were not caused by something more serious.
What Causes Ocular And Visual Migraines
The exact cause of an ocular migraine can be difficult to pinpoint. But it’s believed they occur for the same things that cause migraine headaches.
Migraine headaches have a genetic basis, and some studies say that up to 70% of people who suffer from the disorder have a family history of migraine.
According to the World Health Organization , migraines are caused by the activation of a mechanism deep in the brain that leads to release of pain-producing inflammatory substances around the nerves and blood vessels of the head.
Studies have shown changes in blood flow to the brain during ocular migraines and migraine auras . But exactly why this happens remains unclear.
Common migraine “triggers” that can cause a person to have a migraine attack include:
Stress and lack of sleep also can trigger an ocular migraine or visual migraine.

What Are The Preventive Treatments For Migraine
Many patients with isolated visual migraines, without severe headaches, have relatively infrequent episodes that do not require specific preventive treatments. If a patient is aware of the particular triggers that seem to bring on an episode, then those triggers can be avoided.
In patients where the pattern of migraines includes frequent, severe headaches, it is very reasonable to consider additional preventive treatments. The main goal for any of these strategies is to reduce the overall frequency and severity of the headaches. None of the preventive treatments is a magic bullet that is 100% effective. For example, it would be considered successful if a preventive treatment helped reduce the number of severe headaches from 8 per month to 2-4 per month.
There are numerous medications that can be used as a preventive treatment for migraine. One medication that is used commonly, particularly because it has no side effects, is vitamin B2 . Approximately 100mg of riboflavin daily is thought to improve migraine headaches . One common side effect of riboflavin is that the urine turns bright yellow. Other herbal medications used to reduce migraine headaches include petasites and feverfew.
Can Poor Vision Trigger A Migraine
If you have poor vision, you may squint a lot or hold items up close or far away from your face in order to see them clearly. This can have a negative impact on your vision over time. You could also strain your eyes by reading in poor lighting. When your eyes are constantly straining to see properly, it could trigger a migraine. Having a comprehensive eye exam by a trusted eye doctor is one step you can take to make sure poor vision is one less thing that could trigger a migraine for you.
Additionally, there are eye conditions that can trigger migraines including glaucoma. Glaucoma causes the pressure to build up in the eye and damage the optic nerve. In order to relieve these migraines, the conditions must be treated.
