Yes, there is a fair chance you will have diabetes. Although diabetes has a genetic component, obesity also plays a major role. Insulin functions as a hormone that facilitates transport of glucose (sugar) into cells, and thereby, its usage. In obesity, insulin resistance is a complication hence sugar will remain in the blood, unable to get into cells. If left untreated, it will lead to diabetes; high levels of sugar in blood can lead to blockage of blood vessels in vital organs (kidneys, eyes, heart, brain, etc). Moderate exercise will help a lot in improving insulin resistance; if coupled with dietary modifications, the beneficial effects are numerous, which includes lowering of blood pressure. I do hope this helps and take care always.
