After taking blood pressure medication, why do my feet swell every night?

A patient with high blood pressure complained to the doctor that because he had high blood pressure, his feet were swollen every night and that it was difficult to put on shoes. I don't know why every day after waking up his feet and returning to the original state, he was worried that the swollen feet were a problem with his kidneys, so he went to the hospital to have a kidney function check, but after the examination, he found no problems. The doctor asked him what type of blood pressure medication he usually ate.

He said he himself had been taking an antihypertensive drug like Dipine. The doctor told him that the cause of your swollen feet has been established, and that the swelling of your lower limbs is caused by the *** of the diapine blood pressure medication. <>

The antihypertensive medication on which the patient was taking is a class of vasodilators that is pharmacologically classified as a "calcium channel blocker". The ions formed by calcium are "signaling molecules" that excite and then contract the smooth muscles of blood vessels. In patients with high blood pressure, the blood vessels respond very positively to the "signal molecules", so the blood vessels can easily constrict, and the blood pressure will rise unconsciously.

However, drugs like Dipine can prevent the ions formed by calcium from entering smooth muscle cells, meaning that they prevent "signaling molecules" from transmitting signals to smooth muscle cells, thus lowering blood pressure in dilated blood vessels. <>

Antihypertensive drugs can dilate blood vessels, but have varying degrees of dilation effect on arteries and veins. It works best on arterial dilation, but very weakly on venous and telangiectasia. The capillary network of the human body is like a "pool", with arteries as the "inlet tube" and veins as the "exit tube".

Usually, the inflow and outflow are balanced. When taking horizon drugs to dilate the arteries, it is equivalent to thickening the water inlet pipe and increasing the water inflow; If the veins do not expand, the water production does not change, so the water in the "pool" will gradually increase. <>

Edema caused by horizon medications is reversible and does not cause other harm to the body. Therefore, for mild edema, no intervention is required. In addition, the human body has a process of tolerance to the drug, and this process may resolve on its own as the drug continues.

But for severe edema, even affecting the shoes and pants worn, intervention is necessary.

This is the *** of antihypertensive drugs, which have the effect of dilating blood vessels, and also dilate arteries and veins, so it will cause your feet to be swollen. For mild edema, no intervention is required, and it is really not possible for the hospital to investigate the cause.

Taking blood pressure medicine will not cause swollen feet at night, this situation should be the blood pressure medicine you take, it is not very useful for your body, can not fully absorb this situation, it is recommended to find a professional doctor to prescribe other drugs for you.

It is because you have taken dipine antihypertensive drugs, and the *** of these antihypertensive drugs is that they can cause swelling of the lower limbs.

Analysis: Hello, according to the described situation, the use of antihypertensive drugs will cause edema on the surface of the feet, and timely medication is needed to prevent the further development of edema.

Suggestions: First of all, it is recommended that under the guidance of a doctor, look at the blood pressure control situation, change the drug **, edema may be the cause of nifedipine drugs, and use diuretic drugs as soon as possible. Hope it helps.

Analysis: Hello, according to your description, the patient experienced edema of the lower limbs after overdose of antihypertensive drugs, which may be caused by the kidneys or heart.

Suggestions: It is recommended that you go to the hospital in time to check the urine routine and kidney color ultrasound renal function measurement, rule out other diseases, pay attention to a low-salt and low-fat diet, monitor blood pressure, and adjust the dose of antihypertensive drugs at any time according to blood pressure.

Leg swelling is edema and edema of the lower limbs, and there are many causes of it. 1. Renal edema. In acute nephritis, chronic nephritis or kidney disease, due to the decrease of renal blood flow, sodium and water retention, increased capillary permeability, and too much protein loss in the urine, it will cause the plasma colloidal osmotic pressure to decrease, so that the interstitial space has accumulated and caused edema.

2. Cardiogenic edema. When right heart failure occurs in various heart diseases, the venous pressure rises due to the inability of venous blood to return smoothly, and body fluid leaks into the interstitial space, causing edema. 3. Hepatic edema.

Factors such as liver destruction in cirrhosis, obstruction of portal venous return, increased portal venous pressure, and low plasma albumin in liver failure can cause edema. 4. Dystrophic edema. 5. Localized edema of the lower limbs.

It is mostly caused by the obstruction of the veins and lymphatic vessels of the lower limbs, resulting in the entry of body fluids into the interstitial space, and the embolic phlebitis, lymphangitis, filariasis, pelvic or lower limb tumors compress the veins.

It can be seen that there are many causes of leg swelling, which can be a symptom of systemic diseases or one of the symptoms of local diseases of the lower limbs.

Analysis: Hello, according to the described situation, the use of antihypertensive drugs will cause edema on the surface of the feet, and timely medication is needed to prevent the further development of edema.

Suggestions: First of all, it is recommended to look at the control of blood pressure under the guidance of a doctor, change the ** of the drug, edema may be the cause of nifedipine drugs, and use diuretic drugs as soon as possible. Hope it helps.
