a. "Obesity increases the risk of atherosclerosis."
b. "Obesity increases the risk of hypertension."
c. "Obesity can reduce pumping action of the heart."
d. "Tissue perfusion is diminished by obesity."
D
It is a correct statement that obesity increases the risk of atherosclerosis, particularly if obesity results from excess sugar or saturated fat intake. Obesity does increase the risk of hypertension; even young children should be monitored for hypertension if they are obese. Fat builds up around the heart of obese individuals, resulting in reduced pumping action of the heart. In obesity, the workload of the heart is increased in an attempt to perfuse excess body tissue; however, tissue perfusion is not diminished until the heart is damaged and can no longer adequately perfuse the tissues.
