Can high blood pressure lead to kidney failure?

 


High blood pressure is a leading cause of renal diseases and kidney failure. High blood pressure can constrict and narrow the blood vessels, which eventually damages and weakens them throughout the body, including in the kidneys. The narrowing reduces blood flow.

If your kidneys’ blood vessels are damaged, they may no longer work properly. When this happens, the kidneys are not able to remove all wastes and extra fluid from your body. Extra fluid in the blood vessels can raise your blood pressure, even more, creating a dangerous cycle, and cause more damage leading to kidney failure.

 

Symptoms of High blood pressure and kidney diseases

Most people with high pressure have no symptoms. In rare cases can cause a headache. People may have CKD but not know it because they do not feel sick. A person's glomerular filtration rate (GFR) is a measure of how well the kidneys are filtering wastes from the blood. GFR is estimated from a routine measurement of creatinine in the blood.

Symptoms of advanced kidney disease can include:

·         loss of appetite, nausea, or vomiting
·         drowsiness, feeling tired, or sleep problems
·         headaches or trouble concentrating
·         increased or decreased urination
·         generalized itching or numbness, dry skin, or darkened skin
·         weight loss
·         muscle cramps
·         chest pain or shortness of breath

 

How Can Prevent Kidney Disease?

Many people can keep their blood pressure under control by making lifestyle changes. These changes include maintaining a healthy weight, limiting daily sodium intake, exercising, and limiting alcohol and caffeine consumption. For others, lifestyle changes are not enough to reduce blood pressure levels.
