HIGH BLOOD PRESSURE (HYPERTENSION) IN DOGS/CATS
WHAT THIS SYMPTOM USUALLY MEANS
Hypertension is often silent but can cause sudden blindness, strokes, kidney damage, heart strain, and neurological events. It is strongly associated with endocrine and kidney disease.
MOST COMMON CAUSES
MILD
• Stress during measurement (“white coat effect”)
• Pain temporarily raising blood pressure
MEDICAL
• Kidney disease
• Hyperthyroidism (cats)
• Cushing’s disease
• Diabetes
• Heart disease
• Obesity
• Chronic inflammation
EMERGENCY
• Acute blindness
• Seizures
• Collapse
• Retinal detachment
RED FLAGS
• Sudden vision loss
• Dilated pupils
• Jerky eye movements
• Nosebleeds
• If you’re unsure, treat it as urgent.
AT-HOME CARE
• Reduce stress
• Quiet environment
• Avoid salty foods
These steps do not replace urgent evaluation.
WHAT A VETERINARIAN WILL CHECK
• Blood pressure (Doppler or oscillometric)
• Kidney panel
• Thyroid panel (cats)
• Urinalysis
• Retinal exam
• Heart evaluation if indicated
MOST LIKELY DIAGNOSES
• Kidney disease
• Hyperthyroidism (cats)
• Cushing’s
• Heart disease
• Diabetes
RISK FACTORS
• Senior cats (very common)
• Senior dogs
• Pets with kidney or endocrine disease
WHEN TO SCHEDULE
• Immediately: vision changes
• 48 hrs: elevated BP on home/clinic check
EXPECTED RECOVERY
• Retinas may reattach if caught early
• BP control is typically long-term
LONGEVITY IMPACT
High blood pressure silently damages kidneys, eyes, and the brain—directly reducing lifespan.
LONGEVITY CONSULT
Ideal for pets with early kidney or endocrine disease needing integrated management.
