Have you ever wondered why some people get headaches or migraines more often than others? Scientists say the reason might be hidden deep in our genes — the instructions that shape how our bodies work.
A new study from Australia has found that the genes connected to headaches and migraines might also be related to how our bodies control blood sugar. This discovery could explain why some people are more likely to experience frequent headaches and may open new doors for prevention and treatment.
Migraines are not just bad headaches. They can cause strong, pulsing pain on one side of the head, along with nausea, sensitivity to light, and difficulty concentrating. Some people even experience visual changes before the pain starts.
A migraine attack can last for hours or even days and can completely disrupt daily life. Scientists estimate that around 1 in 7 people worldwide suffer from migraines, making them one of the most common neurological problems in the world.
For years, experts have tried to find out why migraines happen. Many triggers have been identified — such as stress, lack of sleep, hormonal changes, or even weather — but genetics seems to play a big part.
If one or both of your parents have migraines, your chances of getting them are much higher. That means something in your DNA can make you more likely to experience these painful attacks.
At the same time, our genes also influence how our bodies handle blood sugar — the main source of energy for our cells. When you eat food, your body breaks it down into glucose, which travels through your blood to feed your cells.
A hormone called insulin helps move this glucose into the cells. But if your body doesn’t make enough insulin or doesn’t use it properly, blood sugar can rise too high. Over time, this can lead to diabetes and other health problems. Even smaller imbalances in blood sugar can affect energy, mood, and brain function.
Interestingly, people who often get headaches or migraines sometimes notice that their symptoms appear when their blood sugar drops too low or spikes too high. This observation led researchers at Queensland University of Technology (QUT) to wonder whether there might be a deeper link between migraines, headaches, and blood sugar levels — not just coincidence.
To find out, the QUT team analyzed large sets of genetic data from hundreds of thousands of people. Some of these participants had frequent migraines or headaches, while others did not. The scientists compared their genetic patterns and looked for shared traits.
They discovered that many of the same genes involved in blood sugar regulation also appeared in people who suffer from migraines and headaches.
This means that the way our bodies process sugar might directly affect how likely we are to get headaches. For example, some people with genes that make it harder to regulate insulin might be more sensitive to changes in energy levels.
That sensitivity could trigger headaches or migraines when blood sugar rises or falls too quickly. The study even found that people who are genetically prone to migraines may also have a higher risk of developing diabetes or other blood sugar problems later in life.
These findings are exciting because they give doctors new ways to think about migraine treatment. Instead of only focusing on pain relief, doctors might one day help people manage their migraines by keeping blood sugar levels steady.
This could involve dietary changes, medication, or lifestyle habits that prevent big spikes and drops in glucose. Eating regular, balanced meals, staying hydrated, and avoiding too much processed sugar could help some people reduce the frequency or intensity of their headaches.
Of course, not every headache is linked to blood sugar or genetics. Migraines can have many different triggers, and everyone’s body is unique. That’s why it’s important to talk with a doctor before making major changes. Still, this study gives scientists an exciting clue that could help create more personalized treatments in the future.
This research also highlights how complex and connected our bodies are. The same genes that help us process food and energy can also influence how our brains respond to pain. As scientists continue to study these links, we may discover that many conditions share deeper genetic roots than we ever realized.
The study, published in the journal Human Genetics, represents an important step toward understanding how our genes shape both our physical and mental health — and how knowing that can help us live better, healthier lives.
