(Ivanhoe Newswire) -- A new study finds people with migraines are more likely to have blood clots in their veins. Blood clots can cause swelling, pain and even death.
Researchers in Italy looked at 574 people who were at least 55 years old. They were interviewed to determine if they suffered from migraines and their medical records were reviewed to see if they suffered from blood clots. They also underwent ultrasounds to check for blood clots in their necks and thighs. Having blood clots is a condition called venous thrombosis or thromboembolism. These clots can be fatal if they dislodge from the vein and travel to the heart or lungs.

Study authors say 111 people had migraines in the study. A total of 21 people, or 19 percent with migraines also had one or more instance of venous thrombosis. In comparison, only 8 percent of those without migraines had blood clots.
Investigators say its unclear why those with migraines were more likely to have a blood clot. One theory is the blood of people who suffer from migraines may be more prone to clotting.
