Are there any side effects of vasodilators?

The main cause of vasodilator drugs is hypotension caused by vasodilation, which in turn causes a series of symptoms. Patients with mild symptoms may have symptoms such as dizziness, dark eyes, limb weakness, cold sweats, palpitations, and oliguria, and severe patients may present with syncope or shock. Exercise properly, have a regular life, and prevent excessive fatigue, because extreme fatigue will lower blood pressure.

It is necessary to maintain a good mental state, appropriately strengthen exercise, improve physical fitness, and improve the regulatory function of nerves and blood vessels. Caution must be exercised when using these drugs. The patient's age, gender, general condition, presence of hypertension, bleeding tendency, liver function, prothrombin time, coagulation time, and platelet count should be considered.

Vasodilator drugs are mainly to dilate vascular smooth muscle and dilate peripheral blood vessels, taking vasodilator drugs is easy to cause dizziness, palpitations, hypotension, etc., taking vasodilator drugs to consider age, gender, general condition, blood pressure, liver and kidney conditions, whether there is bleeding, prothrombin time, coagulation time, platelet count is normal, need to comprehensively consider whether vasodilators can be used, whether there are contraindications. Any drug has a certain amount of medicine, which will cause some harm to liver and kidney function, so the medication needs to be appropriate, especially within the accurate dosage range, and the drug that can not dilate the blood vessels excessively is easy to cause the patient to have symptoms of prostration, palpitation and dizziness in the early stage, so it is necessary to closely observe the patient's symptoms before using the drug, because some people are relatively large and the symptoms are more obvious.

It is a medicine with three points of poison, and any medicine has ***.

1. Low blood pressure, because vasodilators can dilate peripheral blood vessels, they can lower blood pressure, and when the drug is used excessively, it can cause blood pressure to drop too low.

2. Rapid heart rate, due to the decrease in blood pressure due to vasodilators, the heart rate can be reflexively increased, and when the heart rate increases significantly, it can also lead to the symptoms of palpitation.

There is no harm in reducing the probability of heart disease.

Nobel Laureate in Medicine, Dr. Luis Ignaro, proposed the "nitric oxide regimen". Dr. Ignaro and his colleagues discovered that "nitric oxide is a signaling molecule in the cardiovascular system" that makes contact with arterial muscle cells and relaxes them, dilatating blood vessels and unblocking blood flow. At the same time, it is also a powerful antioxidant, reducing oxidative stress in the body and reducing the probability of heart disease.

It can make the blood vessels weak and unable to withstand the pressure of the blood, which is very dangerous.

Vasodilation is harmful to people, and if you do not give nursing care for a long time after the occurrence of this disease, it is likely to weaken the blood vessel wall, resulting in blood vessel rupture or acute massive blood loss, causing shock, and even death.

Whether there are benefits or disadvantages to vasodilation cannot be generalized. If you have high blood pressure, there are only benefits to dilating blood vessels. Because of the current high blood pressure, the use of vasodilation and diuresis to ** high blood pressure.

If you do not dilate blood vessels, only simple diuresis to ** high blood pressure, then the effect of lowering blood pressure is very poor. Therefore, dilating blood vessels (of course, it should be appropriate, not excessive) is only good for patients with high blood pressure, and there is no harm. If the patient's blood pressure is normal or low, dilating the blood vessels lowers the blood pressure or lowers the already low blood pressure, causing damage to the patient.

Varicose veins refer to the tortuosity and dilation of veins due to factors such as blood stagnation and weak venous walls. Varicose veins can occur in many parts of the body, such as hemorrhoids are actually a kind of varicose veins, and clinical manifestations include esophageal and gastric varices, varicoceles and abdominal wall varices. Varicose veins most often occur in the lower extremities.

It is worth emphasizing that varicose veins are secondary manifestations of other lesions.

Quit smoking, because smoking can change the viscosity of the blood, and the blood becomes viscous and easy to stagnate.

There are many causes of varicose veins of the lower limbs, the most common is simple superficial varicose veins of the lower limbs, which is mainly due to the insufficiency of the femoral saphenous vein valve. Another important ** is seen in primary lower extremity deep vein valve insufficiency (PDVI), which is often associated with saphenous vein valve insufficiency, which often presents with tortuous dilation of superficial veins. In addition, post-deep vein thrombotic syndrome of the lower extremities, in which superficial veins compensate for tortuous dilation occur due to poor deep venous return; Lower extremity arteriovenous fistula and venous malformation hyperosteopathy syndrome can also have superficial varicose veins of the lower extremities; Obstruction of inferior vena cava return, such as Budd-Chiari syndrome, can also lead to varicose veins in the lower extremities.
