You didn't say what kind of stroke your mom had. What was your mom's health like when she had the stroke? In any event, high blood pressure is not a good thing at any age. Get it under control. Clean up your diet. Ask your doctor about an exercise program. Get your weight down if you need to. Drink a glass of milk every day, it helps.
Will it happen to you? It might. What's your health like today? What's your diet like? Do you exercise at least three times a week? Stress? Take a comprehensive look at yourself. What do you see? If you see issues, solve them. Don't depend on pills to fix bad habits. Take control now. It's your body.
My brother had a stroke due to a blood timing disorder. My grandfather had a stroke due to Alzheimers. My other grandfather had a stroke due to arrythmia problems, we were told at the time. I was told I was at a very high risk of having heart disease or a stroke through having complex sleep apnea. My father's blood timing disorder killed him at 38. It is important to get your blood pressure down. Alcohol will increase blood pressure. I don't drink but my blood pressure is starting to rise, so I will be drinking more water, and using stress relieving methods as much as possible. My friend's blood pressure rose when she was dehydrated and rushing around. I guess it comes down to one thing, stroke is caused by a lack of oxygen getting to the brain. Ask your doc for a sleep study test to see if you have sleep apnea.
