Lupus Nephritis or lupus kidney disease is one most complication of SLE. When Lupus causes the immune system to attack kidneys, blood pressure increases easily. If left alone, high blood pressure or hypertension will cause further kidney damage. Therefore, it is necessary to know how to control high blood pressure for Lupus Nephritis patients.
How does Lupus Nephritis cause the increase of blood pressure?
In addition to purifying blood, kidneys also play a vital part in balancing electrolyte and regulating blood pressure. However, when kidneys are damaged, they will fail to maintain normal blood pressure, and three conditions can lead to renal hypertension.
- Fluid and sodium retain in blood: It is reported that about 90% of renal hypertension is associated with fluid and sodium retention, which can cause hypervolemia.
- Hormone disorders: Diseased kidneys are unable to produce enough renin and angiotensin that is another cause of high blood pressure.
- Poor blood flow: Lupus Nephritis leads to damage kidney filters, also known as glomeruli. Then, less blood flows into kidneys.
Medications to lower high blood pressure
People with Lupus Nephritis and high blood pressure may need to take anti-hypertensive agents, which can not only lower hypertension but also slow the progress of lupus kidney disease. Angiotensin-converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARBs) have been proven to have these two effects.
To reduce the side effects of medications and strengthen the pesticide effects, most of patients who have Lupus Nephritis and high blood pressure had better take two or more types of anti-hypertensive drugs, such as beta blockers, diuretics, calcium channel blockers, etc. As for which is suitable for you, you can ask help from your doctor or the online doctor.
Diet plan and exercise
Besides medical therapies, healthy diet and moderate exercise are also helpful for controlling high blood pressure. Restricting the intake of fluid and sodium is the basic requirement for these patients. Many other specific foods such as celery and cucumber also have an effect of lowering hypertension. Try to develop a healthy diet plan and exercise plan with doctor’s guidance.
