Several lifestyle and health-related factors can raise your risk of having a TIA. These include high blood pressure, high cholesterol, diabetes, obesity, and a sedentary lifestyle. Smoking, heavy alcohol use, and a diet high in saturated fats or sodium also contribute. Certain illicit drugs and some birth control pills can increase the likelihood of clot formation. Managing these risks — through diet, exercise, medication, and quitting smoking — is essential to lowering your chances of both a TIA and a full stroke.
