Answer:Sometimes STDs or other sicknesses, and the risk of getting pregnant if you are female .
Explanation:
-Obesity = more volume (fat) that must be supplied blood —> extra pressure on your heart to push blood further —> thickening of heart muscle
-Obesity is mostly caused by eating unhealthy foods whose main detriment to cardiovascular health is that these foods can turn into plaque that build up in the artieries in your heart (atherosclerosis; this usually is the cause of coronary artery disease)
-Another common health condition that can affect your cardiovascular health is a high salt diet. Since salt encourages the retaining of water in your blood, it increases the volume in your blood vessels, stretching them in much wider diameters than they would normally be able to handle
This in turn damages the inside of those blood vessels, and the tissue under the inside of the blood vessels likes to pick up chloesterol, which sticks to cholesterol, which can lead to blockages of plaque inside those arteries, potentially leading to the complete blockage of the artery. If this occurs in the heart, in can cause heart attack, as the heart will not receive enough oxygen from blocked blood flow and the heart cells will begin to die.
