1. Why his BP fluctuates
Normal physiology – Everyone’s BP varies across the day (sleep, meals, stress, activity).
Hypertension not well-controlled – Since he takes Amlodipine only “as needed”, his BP control is erratic. BP meds are usually prescribed regularly, not on-and-off, otherwise you see spikes and dips.
Tobacco (Khaini) – Nicotine causes vasoconstriction + transient BP rise, followed by a drop, worsening fluctuations.
Age (44 yrs) – With age, blood vessels stiffen and the body’s ability to regulate sudden BP changes weakens.

2. Why dizziness after meals
This sounds like Postprandial Hypotension (PPH) – common in older adults and hypertensives.
After eating, blood is diverted to the digestive system.
Normally, the heart and vessels adjust by increasing heart rate and vascular tone.
In some people (especially with BP meds, autonomic dysfunction, or vessel stiffness), this adjustment fails → drop in BP → dizziness/lightheadedness after meals.

3. Red flags to consider
If dizziness is severe, associated with fainting, chest pain, palpitations, or shortness of breath → urgent evaluation.
Longstanding uncontrolled BP can affect heart, kidneys, and brain → so this needs regular follow-up, not just PRN medication.

4. What you should do
🔹 Medical review: He needs a physician/cardiologist to:
Check if he actually has sustained hypertension (24-hr ambulatory BP monitoring is best).
Decide if he should be on a regular daily antihypertensive, instead of PRN Amlodipine.
Rule out other causes of dizziness (anemia, arrhythmias,
diabetes with autonomic neuropathy, inner ear causes).
🔹 Lifestyle adjustments for post-meal dizziness:
Smaller, more frequent meals rather than large ones.
Limit high-carb meals (these drop BP faster).
Stay upright for 30–60 min after eating.
Adequate hydration.
Avoid alcohol and tobacco (khaini worsens vascular instability).

✅ Bottom line:
His symptoms are very likely due to post-meal blood pressure drops + irregular use of antihypertensives. With proper evaluation and regular BP management (plus stopping khaini), this can usually be controlled.
