How Is High Blood Pressure Associated with Lupus Nephritis

2012-10-11 16:43

High Blood Pressure Associated with Lupus NephritisHigh blood pressure is closely associated with Lupus Nephritis because once the disease attacks, his or her kidneys have been impaired already. Damaged kidneys often lead to elevated blood pressure from those two aspects.

Once blood pressure rises, the internal pressure of glomeruli also elevates. The high blood pressure forces glomeruli to function even harder than normal which would lead to their overwork and result in the damages in the end. Plus, hypertension accounts for the ischemia and anoxia of kidneys, all those factors contribute to your damaged kidneys.

Hypertension exists when Lupus Nephritis forms for a long time. Its clinical characteristics can be:

The incidence rate of elevated blood pressure increases gradually along with the duration of LN. Take this for example, only 30.5% of patients with LN suffer from rise in blood pressure within 3 years after their onset, but more than 46% of patients are complicated with hypertension when their course of disease exceeds 5 years.

To make things worse, if a patient develops Lupus Nephritis and has family history of elevated blood pressure, they are more prone to suffer from increased blood pressure than those without.

The extent of their proteinuria is also closely connected with the incidence rate of increased blood pressure.

For people with LN, what should they do about their high blood pressure?

Monitoring blood pressure ever day by blood pressure cuff can greatly help LN patients.

Diet modification should be adopted along with blood pressure monitoring. Be more exact, sodium is needed to cut down because overmuch salt intake contributes to high blood pressure.

For those who have already suffered from hypertension and Lupus Nephritis, taking a good rest and moving slowly so as to prevent faint from happening.

Once serious headache, nausea, vomiting or seizure etc, the patients should be taken to hospital as soon as possible.
