Nicotine can lead to vasoconstriction of uteroplacental vessels, reducing the delivery of both nutrients and oxygen to the fetus. [ 113 ] As a result, nutrition is re-distributed to prioritize vital organs, such as the heart and the brain, at the cost of less vital organs, such as the liver, kidneys, adrenal glands, and pancreas, leading to ...
The extent of vasoconstriction may be slight or severe depending on the substance or circumstance. Many vasoconstrictors also cause pupil dilation. Medications that cause vasoconstriction include: antihistamines, decongestants, and stimulants. Severe vasoconstriction may result in symptoms of intermittent claudication. [1]
Additionally, nicotine causes systemic vasoconstriction, including constriction of coronary arteries, which can reduce blood flow to the heart. Long-term exposure to nicotine may impair endothelial function, potentially contributing to atherosclerosis .
Even when marked, hypocapnia is normally well tolerated. Symptoms include tingling sensation (usually in the limbs), abnormal heartbeat, painful muscle cramps, and seizures. Acute hypocapnia causes hypocapnic alkalosis, which causes cerebral vasoconstriction leading to cerebral hypoxia, and this can cause transient dizziness, fainting, and ...
