What you experienced is quite common and usually does not mean you have severe hypertension. Blood pressure can fluctuate significantly within minutes due to several factors.
The readings you had were:
• 140/90 (first check)
• 173/113 (ER digital machine)
• 155/84 (automated arm device)
• 135/80 (manual reading)
The manual reading of 135/80 mmHg is generally considered more reliable, especially when taken properly by a trained person with a stethoscope. Automated machines can sometimes give higher readings due to anxiety, movement, wrong cuff size, or improper positioning.
A very common reason for sudden high readings in hospitals is White Coat Hypertension, where BP temporarily rises due to stress, anxiety, or the hospital environment.

Why the BP fluctuated?
Blood pressure can change because of:
• Anxiety or stress while in hospital
• Recent walking, talking, or movement before measurement
• Full bladder or dehydration
• Incorrect cuff size or arm position
• Different machines and measurement techniques
• Acid reflux discomfort, which can temporarily increase BP due to stress response
It is normal for BP to vary 10–30 mmHg within minutes depending on these factors.
Next Steps
Instead of relying on a single reading, doctors usually confirm hypertension using:
• Home BP monitoring for 5–7 days
• Measure BP twice daily (morning and evening)
• Sit quietly 5 minutes before measuring
• Record the average readings

Health Tips
• Avoid caffeine, smoking, or exercise 30 minutes before BP check.
• Sit with back supported, feet flat, arm at heart level.
• Use the same arm each time.
• Take 2 readings 1–2 minutes apart and average them.
Also, since you mentioned reflux symptoms, conditions like Gastroesophageal Reflux Disease can sometimes cause anxiety or chest discomfort that makes BP temporarily rise.

✅ Bottom line: Your manual BP of 135/80 is reassuring, and the fluctuations likely occurred due to stress or measurement differences.
