Blood pressure and kidney health

The two-way connection

Persistently high pressure can injure the kidney's small blood vessels and filters. Damaged kidneys may retain sodium and fluid or alter hormone systems that regulate pressure, creating a cycle.

Blood-pressure management is also cardiovascular care because CKD increases the risk of heart disease and stroke.

A more reliable home reading

Bring the monitor to an appointment occasionally so technique and device accuracy can be checked.

• Avoid exercise, caffeine, and smoking for about 30 minutes beforehand when possible.
• Empty your bladder, sit quietly for five minutes, support your back and feet, and keep legs uncrossed.
• Use a validated upper-arm cuff of the correct size on bare skin, with the arm supported at heart level.
• Take the number of readings and follow the schedule agreed with your care team; record the time, symptoms, and missed doses.

Targets and medicines

Guidelines use standardized clinic measurements, which may not match a hurried office reading or an unstructured home reading. Your target may differ based on age, albuminuria, diabetes, dizziness, falls, pregnancy, other conditions, and treatment tolerance.

ACE inhibitors and ARBs are often used when CKD is accompanied by albuminuria, but they are not right for every person. Creatinine and potassium may be checked after starting or changing a dose. Do not combine, stop, or adjust them without clinical guidance.

When a reading needs urgent action

If a reading is unexpectedly high, sit quietly and repeat it using correct technique. Follow the urgent plan given by your care team.

A repeated reading around 180/120 mmHg or higher with chest pain, severe breathlessness, new weakness or numbness, difficulty speaking, confusion, vision change, or another severe symptom can be an emergency. Contact local emergency services rather than using ENKI for urgent care.
