What to do with my high blood pressure at such a young age?

I am 21 years old, Male and am from India. I have a high blood pressure of 140/96. I weigh 93 kgs and am obese. I guess my cholesterol levels are also very high. What are the possible dangers I might face ? What corrective actions to take ? My parents also have BP but not very high.

I’ve just started swimming for around 1 hour (30 mts of actual swimming). Is that enough ? Is heart attack at such a young age possible ? Kindly advise.
