Headache is a common sign of kidney disease. Therefore, you should not neglect unexplained headache and delay the treatment. The condition in kidney disease is mainly attributable to the following causes.
1. Renal hypertension
Renal hypertension can cause headache in kidney disease. As the number of healthy nephrons reduces, more renin will be produced which is a hormone that can regulate blood pressure. With the progression of the disease, blood pressure will elevate persistently. It is very difficult to correct renal hypertension.
After kidneys are damaged, less EPO will be produced which can stimulate the production of red blood cells. Additionally, dangerous levels of uremic toxins build up in body, which can shorten the life span of platelet and red blood cells significantly. Therefore, anemia is very likely to occur in kidney disease, thus leading to anemic headache.
After kidneys are damaged seriously, a large amount of proteins will leak into urine through the filtering units in kidneys, resulting in hypoproteinemia. As proteins are antibodies in body, protein loss can lead to weak immunity. In addition, less urine output can lead to retention of metabolic toxins and metabolic disorder as well as acidosis.These conditions can attribute to headache in kidney disease.
The above are the major causes of headache in kidney disease. If the above conditions can be controlled, the headache will be relieved. However, as the underlying cause of headache in kidney disease is kidney impairment, the primary treatment goal is to treat kidney disease itself and restore the impaired kidneys.
