Widening of blood vessels do occur that aren\u2019t due to underlying diseases. Examples include warm temperatures such as time spent in a hot spar, exercise, medication side effects, eating chili pepper or alcohol and so on.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Applying menthol and eucalyptus containing ointments like \u2018siddhalapaya\u2019 so popular in Sri Lanka, and Tiger balm, have the same effect of dilating the blood vessels.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Certain medications also open or dilate blood vessels. This is caused from preventing the muscles from tightening and the walls from narrowing. This results in blood flow more easily through these vessels, easing the strain on the heart to pump as hard, reduces blood pressure.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Examples of lung vasodilators include oxygen, nitric oxide, and nitroprusside.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">A vasodilator is a drug that causes vasodilation, a widening (opening) of blood vessels that results from relaxation of the smooth muscle of the vessels. What widens in vasodilation is the diameter of the interior (lumen) of the vessel. The opposite of vasodilation is vasoconstriction.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Angiotensin discussed when ACE inhibitors and ARBs in previous videos, has a constricting effect on blood vessels. ACE inhibitors through the action on angiotensin converting enzymes, dilate blood vessels and reduce blood pressure.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Similarly, ARBs i.e., angiotensin receptor blockers are also another type of medicine that enlarges blood vessels. They work by blocking angiotensin from attaching to the smooth muscles of blood vessels<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Nitrates are converted to nitric oxide, which activates another chemical that causes the veins and arteries to open.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Doctors give nitrates to treat angina or cardiac pain.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Sildenafil (Viagra), tadalafil (Cialis) increase the blood lowering effects of nitrates and may cause excessive blood pressure drop.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Patients taking a medicine that is a nitrate should not take sildenafil (Viagra), tadalafil (Cialis),<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">The calcium channel blocker (CCBs) was discussed in a previous video talk, used for lowering blood pressure by slowing the heart rate. Calcium causes the heart and arteries to contract more strongly, thereby increasing blood pressure. By blocking calcium, calcium channel blockers allow blood vessels to relax or dilate and open, thereby lowering the blood pressure.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">There are other drugs like Prazosin an adrenergic receptor blocker or called alpha blockers on the muscle cells that surround blood vessels can cause dilation of the blood vessels, and consequently decreases the resistance of blood flow.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">CGRP or Calcitonin Gene- related peptide: a novel neuropeptide from the calcitonin gene is the most potent vasodilator known.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Calcitonin gene has been shown to give rise to a peptide. Calcitonin gene related containing neurons in several vessels and vascular beds, including the skin and coronary circulation in humans have been reported as potent vasodilators. CGRP is primarily released from sensory nerves and thus is implicated in pain pathways.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Veggies that cause vasodilation of blood vessels<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Leafy greens like spinach and collard greens are high in nitrates, which your body converts into nitric oxide, a potent vasodilator. <\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Eating nitrate-rich foods may help improve circulation by dilating blood vessels, allowing your blood to flow more easily.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Other foods that cause vasodilatation include<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Cayenne Pepper cause vasodilatation and increase of blood flow by stimulating the release of nitric oxide and other vasodilators.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Pomegranate<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Onions<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Cinnamon<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Garlic- has sulfur compounds which includes allicin is a vasodilator.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Fatty fish<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Beets<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Turmeric<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Citrus fruits<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Walnuts<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Tomatoes<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Berries<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Ginger<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">This video talk emphasizes the importance of vasodilatation of blood vessels to increase and stimulate blood flow, and reduce the blood pressure and strain on the heart.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Leading a healthy lifestyle, staying active by daily exercising, maintaining a healthy weight and eating a well-rounded diet can boost your blood flow and overall health.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Hope this video talk was useful.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">My mission and vision is to see that all Sri Lankans and others world-wide, imparting a balanced, proved medical knowledge will benefit for better understanding of health issues.<\/span><br \/>\n<span style=\"font-size: 16px; color: #000000;\">Stay safe and goodbye for now.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #000000; font-size: 16px;\">Disclaimer:<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #000000; font-size: 16px;\">The information contained in this article is for general information purposes only, and whilst the author will endeavour to keep the information up to date and correct, eLanka makes no representations or warranties of any kind, express or implied, about the completeness, accuracy, reliability, suitability or availability with respect to the eLanka website or the information, products, services, or related graphics contained in this article for any purpose.
