Shock could induce many different things to happen to the body. People that go through an traumatic event raises a persons blood pressure, if there is an underlining health problem it could induce: bph, seizure, vomiting, dizziness, stroke, and even a heart attack. So the answer is yes.

The upsetting stimuli would be processed by the higher centers of the central nervous system and relayed to the hypothalamus. The hypothalamus could suppress the vasomotor center of the medulla, resulting in fewer sympathetic impulses to peripheral blood vessels. This would cause a decrease in sympathetic tone in the smooth muscle of the blood vessels, resulting in vasodilation. The vasodilation would cause blood to pool in the extremities, decreasing the amount of blood returning to the heart and producing shock.
