The primary kidney problem that leads to high blood pressure is that of a blockage of blood flow to one or more kidneys as well as kidney diseases. In response to a lack of adequate blood flow, the kidneys release angiotensin into the blood that causes constriction of the blood vessels and an increased blood pressure. The adrenal cortex also releases aldosterone when angiotensin is released.
To understand the kidney problem more easily, you need to understand how angiotensin is made. It is made by a precursor molecule called angiotensinogen. This is an alpha-2-globulin that is released by the liver. It is a protein made from 453 amino acids. The molecule, angiotensin I, is made by the action of renin (made by the kidneys when blood pressure is perceived to be low) on the protein angiotensinogen. Angiotensin I is simply a precursor to angiotensin II.
The kidney problem in high blood pressure gets worse when an enzyme called ACE (angiotensin converting enzyme) transforms angiotensin I to angiotensin II. The angiotensin II is what causes the blood pressure to rise. The molecule does degrade into angiotensin III and angiotensin IV that have lesser activity on blood pressure.
The primary kidney problem impacting high blood pressure is the constriction of the arteries and veins by angiotensin II. It also causes adhesion and the aggregation of platelets, promoting blood clots. In addition, it is possibly playing a role in the thickening and enlargement of the heart. Angiotensin II also increases the resorption of sodium by the kidneys, which also worsens the blood pressure. In an attempt to fix the low blood flow to the kidneys, the molecule also increases the rate at which blood flows through the kidneys.
In order to fix the kidney problem causing high blood pressure, there are medications now that help block the affects of the molecules involved. The most commonly used medication is called an ACE inhibitor and includes medications like Vasotec, Univasc, Prinivil and Zestril. They block the conversion of angiotensin I to angiotensin II. Newer medications block the receptor site for angiotensin II.
There is a relatively uncommon type of kidney problem causing high blood pressure. That condition is called renovascular hypertension. It is a condition to be examined for in cases of high blood pressure in teens and other young people. It occurs when there is a natural narrowing of one of the renal arteries leading to the kidneys. This causes an increase in the release of renin from the kidney and the cascade toward having high levels of angiotensin II is begun. The only good way to evaluate for this disease is to do an X-Ray dye study particularly one using a catheter into the renal arteries to check for narrowing.
Are you someone who has been diagnosed with high blood pressure? If so, you undoubtedly want to lower your high blood pressure through high blood pressure treatments. But there are many situations which will naturally push your ?buttons,? potentially leading to an increase in high blood pressure symptoms(http://www.mitamins.com/disease/High-Blood-Pressure.html). At those times, you need to be able to choose an immediate treatment of high blood pressure symptoms in order to keep yourself healthy.
Here, we'll look at some common causes of high blood pressure symptoms creating and what high blood pressure treatments are available in such scenarios.
1. Someone Makes You Angry
Maybe it's your spouse. Or your kids. Or your boss. Or your neighbor. Regardless, you're mad, and you can feel the blood throbbing in your veins. our heart is pounding, your face is red, and high blood pressure treatment is the last thing on your mind.
Stop!
Before you allow yourself to sabotage your health, know that you hold the key to the treatment of high blood pressure symptoms. And that secret weapon is relaxation.
First, when someone makes your blood boil, remove yourself from the situation as quickly as possible. Though it might take a few moments or seem awkward, escape from the room or the area. That way, you can calm yourself down, your high blood pressure will drop, and you'll be able to come back to the conversation (if you want) with a calmer presence.
2. You're Exercising Too Hard
Yes, sports can actually be a good high blood pressure treatment, but it can also be a problem if you're out-of-shape or if your blood pressure level has recently spiked to a dangerous point.
If you're starting out, make sure you exercise your body the right way. Warm up slowly, and try not to overdo it. If you feel like your heart is pounding, your head is throbbing, and/or you are going to pass out if you continue, cease all activity. If you must lie down, raise your legs above your heart, which will be less taxing for you. The best treatment of high blood pressure symptoms at this point is to simply allow your heart to return to its natural state. Otherwise, you could risk a heart attack or stroke.
Again, this isn't to suggest that activity is bad; it's certain not. In fact, it's one of the best things you can do to lower your high blood pressure(http://www.mitamins.com/disease/High-Blood-Pressure.html)! But it's important not to be a ?weekend warrior.? Know your limitations, and you'll be healthier and happier.
3. You've Gained Quite a Bit of Weight
You couldn't resist ordering cheesecake every night during your vacation and the buffets were just chock full of all sorts of goodies. Now, you're back home and it's obvious that you've gained at least ten pounds in the past month: not a good sign. You're definitely in need of some high blood pressure treatment(http://www.mitamins.com/disease/High-Blood-Pressure.html) options.
First, stop overeating. Avoid all high sugars, high fats, and salty foods. Yes, your taste buds might be screaming for sodium and butter, but your high blood pressure symptoms are telling a different story. Resist the temptation until your weight is under control; that way, you'll be treating your high blood pressure with the importance it deserves.
